Computer Does Not Start and Emits a Beep Code

What to do when beep codes occur?

A beep code usually means a basic function was unable to start. A basic function might be reading memory, displaying video, or being able to send information to a hard drive. The most common problems that cause beep codes are memory and heat-related failures caused by a build-up of dust in critical cooling areas.
Use the beep code tables in this document to help find what hardware component is causing the issue. This might reduce the time required to find the hardware component that needs adjusted, reseated, or replaced.
Step 1: Remove dust from cooling areas
Step 1: Remove dust from cooling areas
If your computer is new and has never been used before, you can skip this step.
Over time, dust can collect in the cooling vents of your computer. Too much dust can block airflow, causing sensitive components to overheat and fail. Before troubleshooting for startup codes, it is important to remove any dust that may have accumulated.
While wearing eye protection, use canned air or the end of a vacuum cleaner to remove dust from vents, preferrably outdoors.

If your computer does not start, first reset all power to device. Hopefully, the problem is temporary and can be fixed by performing the following steps:

    Disconnect all peripheral devices such as printers, USB storage devices and media cards.
    Disconnect the power cord from the computer.
    Press and hold the power button for at least 15 seconds until the power LED on the power supply is off.
    Reconnect the power cord, and press the Power button .
    Listen for sounds of drives and fans turning.
    If the computer still fails to start and emits beeping sounds, continue to the next section.

Step 3: Write down the LED or beep code
 

Use the following steps to write down the error conditions onto a piece of paper.

 -Press the power button to turn on the computer.
 -Listen to your computer for any loud beeping noises. If your computer makes a beeping noise, note the type and number of beeps between pauses. For example: two long beeps followed by one short beep.
 -On a piece of paper, write down what you have noted to remember the error when doing the next steps.

Step 4: Match the code to a suspected hardware component

 
Consult the Beep code descriptions section in this support document to try and find the component that is having a problem. You can use this information in the next step when performing the troubleshooting. Or, in the event your computer requires service, you can use this code and information when talking with the service personell.

Step 5: Isolate and fix the problem

 

-Turn on the computer.
-Check the system fan and power cable:
-Turn off the computer by holding the power button for five seconds.

- Disconnect the power cord and then disconnect all external cords from the computer.

-Remove the side panel to open the computer.

-If the system fan was not spinning, make sure the system fan power cable is connected to the correct pins on the motherboard. Replace the fan if it was making excessive noise or was not spinning.-

If you had to plug in or replace the fan, replace the side panel, plug in the power cord and turn on the computer. If the beeps continue, continue to the next step.

Disconnect the power cord and remove the side panel and perform each of the following tasks, in order, until the beeping stops:
Before starting each task, unplug the power cord and remove the side panel.
After completing a task, replace the side panel, connect the power cord, turn on the computer, and listen for a beep code.
   - Clean internal cooling components that have become clogged with dust. If beeping continues, continue to the next step.
   - Remove a memory module.
   - If the computer stops beeping, the memory module might be bad, is the wrong type of memory for the motherboard, or was not fully seated or connected. Reinsert the memory into the socket to see if a connection was the problem; otherwise replace the module.
    Remove each memory module, replacing the one that was previously removed. If beeping continues after checking all the memory modules, continue to the next step.
    If the computer has a graphics adapter, remove it.
    If the beep code changes or continues with the same beep pattern after removing the graphics adapter, the adapter might still be good. Reseat the graphics adapter into its socket and continue to the next step.
    -If the beep code goes away, the graphics adapter might be bad. Try reseating the graphics adapter, making sure it is fully locked into the connector on the motherboard. If problems continue, replace the adapter.
    -Remove a PCI card.
    -If the beep code goes away, the card might be bad. Try reseating the card into its connector on the motherboard. If problems continue, replace the card.
    -Remove each PCI card, replacing the one that was previously removed. After checking all cards, if beeping continues, continue to the next step.
   - Disconnect each hard drive and CD or DVD drive cable (IDE and ATA) from the motherboard socket. Disconnect each drive cable, replacing the one that was previously disconnected, until all cables have been checked.
    -If the beep code goes away, the cable or socket is probably bad. Look for bent pins inside the IDE socket on the motherboard and straighten any bent pins. Try reseating the cables into the connectors. If problems continue, the drive itself might be bad and might need replacing.
   - After checking all connections, if beeping continues, continue to the next step.
    -At this point, the problem is probably the motherboard or processor. Make sure any jumpers on the motherboard have not fallen off their pins and into the case. Make sure jumpers are set correctly. Otherwise, have the computer serviced by HP or by a qualified service center.

How to repair computer errors

When you have a computer error it can be very frustrating, especially if the error prevents software from running or your computer even starting. If you add the internet to the mix, your computer will get viruses, spyware, adware and other malicious software that will cause errors on your machine.Spyware is perhaps one of the most dangerous types of PC infections to date. If a computer gets infected with spyware, a person could keep track of your every keystroke, email, website visit and other confidential conversations you might partake in. So if you do things like online banking, a person could use the spyware to find out all of your information and do what illegal acts they want to with it.
The next internet threat is adware and isn’t as dangerous as spyware, but can be very annoying. I despise any company or individual who develops adware because it is intrusive and no better then spam. Adware is advertisement software that usually attaches to free software that most people download. And even if you are connected to the internet or not adware can show advertisements. It will also do this even if the original download is not running. Adware ads come in many different forms, like pop-ups, URL redirection and many other things that anyone would find annoying.
Most people use Windows, if you don’t then you can skip this part. If you do, then you should know that Windows uses registry files and these registry files could be causing errors for you. When registry files have invalid entries this can cause error messages and crashes. Also if you remove orphaned references in your registry you can increase your PC’s performance and stability.
Viruses are the main reason people have computer errors, especially if you are connected to the internet. If the computer does not have any internet connection, then a virus could have only gotten on their by someone inserting data that has been infected by a malicious virus.
A Trojan virus is the most common type of virus and you should know how it works to avoid it. A Trojan virus hides in a program that appears as something you may think is safe, but hidden inside is usually something harmful, like a virus. Trojans are so common because you may download a game or even a picture thinking it is harmless, but once you run the file, the virus gets let loose.
If this is the first time you have ever tried to remove these errors from your computer, then you can expect to find a lot. That is why I recommend you get a good computer error removal program and use it at least once a month.
With this knowledge of all the different types of computer errors, you should be able properly diagnose what is causing the errors on your computer and fix it. Do not be discouraged if all errors aren’t fixed right away, as it could be all of the above. If you do have every type of error, then you would have to take removal steps for each type of error.

Installing MATLAB: processor is missing the SSE2 instructions

.

 Enter the chroot environment:
Code:

dchroot -d


2. Several key packages may be missing which require installation:
Code:

sudo apt-get install libxp6 libxt6 libxtst6


3. Now insert the matlab cdrom, remount it and run the install:
Code:

sudo umount /media/cdrom sudo mount -t iso9660 /dev/cdrom /media/cdrom
sudo mkdir /opt/matlab7 cd /opt/matlab7 sudo sh
/media/cdrom/install_unix.sh -glnx86


4. The new chroot32 environment for some reason still considers itself
to be of ia64 architecture. So the matlab install script merrily churns
away, installs all the binaries to .../glnx86 directories and makes its
own scripts point to .../glnxa64 directories which don't exist. Very
annoying, so we simply symlink wherever necessary:
Code:

cd /opt/matlab7/bin sudo mv glnxa64 glnxa64.old sudo ln -s glnx86
glnxa64 cd /opt/matlab7/extern/lib sudo ln -s glnx86 glnxa64 cd
/opt/matlab7/sys/java/jre sudo ln -s glnx86 glnxa64 cd
/opt/matlab7/sys/java/jre/glnx86/jre1.4.2/lib sudo ln -s i386 amd64


5. The last step is because matlab can't access a terminal window. I'm
not sure how this works, but the /chroot/dev/pts directory is not
properly mounted. You need to remount this. So in a new terminal window
(not chroot) go:
Code:

sudo umount /chroot/dev sudo mount --rbind /dev /chroot/dev


6. Now finally to remove the oscheck error message, open up the
oscheck.sh file:
Code:

sudo gedit /chroot/opt/matlab7/bin/util/oscheck.sh

Goto line 150, comment it out and insert a version number so looks like
follows:
Code:

# ver=`/lib/libc.so.6 | head -n 1 | sed -e "s/^[^0-9]*//" -e "s/[
,].*$//"` ver=`objdump -x /lib/libc.so.6|egrep " GLIBC_"|tail -1|awk
-F_ '{print $2}'`


7. Now you can type "matlab" and it should work without any errors or
fuss.

How To Fix Xlive.dll Not Found or Missing Errors

Xlive.dll error messages might appear while using or installing certain programs, when Windows starts or shuts down, or maybe even during a Windows installation.

The context of the xlive.dll error is an important piece of information that will be helpful while solving the problem.
Cause of Xlive.dll Errors

Xlive.dll errors are caused by situations that lead to the removal or corruption of the xlive DLL file.

In some cases, xlive.dll errors could indicate a registry problem, a virus or malware issue or even a hardware failure.

How To Fix Xlive.dll Errors
Important: Do not download xlive.dll from a "DLL download" website. There are many reasons why downloading a DLL file is a bad idea. If you need a copy of xlive.dll, it's best to obtain it from its original, legitimate source.

Note: Start Windows in Safe Mode to complete any of the following steps if you're unable to access Windows normally due to the xlive.dll error.

    Download Games for Windows Live. The xlive.dll file is included in this download from Microsoft and installing it will likely replace the xlive.dll file, fixing this problem.

    Restore xlive.dll from the Recycle Bin. The easiest possible cause of a "missing" xlive.dll file is that you've mistakenly deleted it.

    If you suspect that you've accidentally deleted xlive.dll but you've already emptied the Recycle Bin, you may be able to recover xlive.dll with a free file recovery program.

    Important: Recovering a deleted copy of xlive.dll with a file recovery program is a smart idea only if you're confident you've deleted the file yourself and that it was working properly before you did that.

    Run a virus/malware scan of your entire system. Some xlive.dll errors could be related to a virus or other malware infection on your computer that has damaged the DLL file. It's even possible that the xlive.dll error you're seeing is related to a hostile program that's masquerading as the file.

    Use System Restore to undo recent system changes. If you suspect that the xlive.dll error was caused by a change made to an important file or configuration, a System Restore could solve the problem.

    Reinstall the program that uses the xlive.dll file. If the xlive.dll DLL error occurs when you use a particular program, reinstalling the program should replace the file.

    Important: Try your best to complete this step. Reinstalling the program that provides the xlive.dll file, if possible, is a likely solution to this DLL error.

    Update the drivers for hardware devices that might be related to xlive.dll. If, for example, you're receiving a "The file xlive.dll is missing" error when you play a 3D video game, try updating the drivers for your video card.

    Note: The xlive.dll file may or may not be related to video cards - this was just an example. The key here is to pay very close attention to the context of the error and troubleshoot accordingly.

    Roll back a driver to a previously installed version if xlive.dll errors began after updating a particular hardware device's driver.

    Run the sfc /scannow System File Checker command to replace a missing or corrupt copy of the xlive.dll file. If this DLL file is provided my Microsoft, the System File Checker tool should restore it.

    Install any available Windows updates. Many service packs and other patches replace or update some of the hundreds of Microsoft distributed DLL files on your computer. The xlive.dll file could be included in one of those updates.

    Test your memory and then test your hard drive. I've left the majority of hardware troubleshooting to the last step, but your computer's memory and hard drive are easy to test and are the most likely components that might cause xlive.dll errors as they fail.

    If the hardware fails any of your tests, replace the memory or replace the hard drive as soon as possible.

    Repair your installation of Windows. If the individual xlive.dll file troubleshooting advice above is unsuccessful, performing a startup repair or repair installation should restore all Windows DLL files to their working versions.

    Use a free registry cleaner to repair xlive.dll related issues in the registry. A free registry cleaner program may be able to help by removing invalid xlive.dll registry entries that might be causing the DLL error.

    Important: I rarely recommend the use of registry cleaners. I've included the option here as a "last resort" attempt before the destructive step coming up next.

    Perform a clean installation of Windows. A clean install of Windows will erase everything from the hard drive and install a fresh copy of Windows. If none of the steps above correct the xlive.dll error, this should be your next course of action.

    Important: All the information on your hard drive will be erased during a clean install. Make sure you've made the best attempt possible to fix the xlive.dll error using a troubleshooting step prior to this one.

    Troubleshoot for a hardware problem if any xlive.dll errors persist. After a clean install of Windows, your DLL problem can only be hardware related.

Applies To

The xlive.dll error message could apply to any program or system that might utilize the file on any of Microsoft's operating systems including Windows 7, Windows Vista, Windows XP, and Windows 2000.

The good news is that the large part of them are simple to locate and fix, even if, like most people, you are not a computer expert. In the paragraphs that follow, I'll let you in on how you can have the ability to quickly rid your computer of these irritating pc errors

I assume that since you've been using your computer, you must have already experienced various conflicts linked to the windows system. Regrettably, the majority of users don't realize the truth that in most cases one particular cause is responsible for all these problems - the windows registry. Without that key information, a lot of pc users dip into their wallets and spend too much time on unneeded and often ineffective solutions.

One thing that is required of you right away when your computer encounters Windows autorun exe errors is to investigate whether or not the registry is corrupted. This segment of your system has to monitor all your actions with respect to sw and hw installations, removals, and updates management. It catalogues, to name one function, the exact position of all exe files on your hard disk. The consequence of a damaged registry can be to name one potential problem, the inability of your windows program to locate the path of a specific executable and consequently you end up with annoying pop-up errors.

With your new understanding of what it means to get Windows autorun exe errors take the opportunity to get started on a "cure" before it bothers you again. Playing around with your windows registry independently is probably a too sophisticated process, but you can choose one of the following: either hire a technician (expensive) or installing a registry fix software. A well designed registry cleaning and repairing software from a maker you can trust will efficiently and simply repair your windows registry. I strongly encourage you to download and install one of these great tools and start scanning for free; there are very high chances that you can finally free your windows of this and other irritating and time-wasting issues in just a few minutes from now..

How To Troubleshoot a Computer That Turns On But Stops Booting During the POST

Troubleshoot the cause of the BIOS error message you see on the monitor. These errors during the POST are usually very specific so if you've been fortunate enough to receive one, your best course of action is to troubleshoot to the specific error you see.

If you don't fix the problem by working through the specific error during the POST, you can always return here and continue with the troubleshooting below.

Clear the CMOS. Clearing the BIOS memory on your motherboard will reset the BIOS settings to their factory default levels. A misconfigured BIOS is a common cause of a computer locking up during the POST.

Important: If clearing the CMOS does fix your problem, make any future settings changes in BIOS one at a time so if the problem returns, you'll know which change caused your issue.

Test your power supply. Just because your computer initially turns on does not mean that the power supply is working. The power supply is the cause of startup problems more than any other piece of hardware in a computer. It very well could be the cause of your problems during the POST.

Replace your power supply immediately if your tests show a problem with it.

Important: Do not skip a test of your PSU thinking that your problem can't be with the power supply because your computer is receiving power. Power supplies can, and often do, partially work and one that isn't fully functional must be replaced.

Reseat everything inside your computer case. Reseating will reestablish the the cable, card, and other connections inside your computer.

Try reseating the following and then see if your computer boots past the POST:

Note: Unplug and reattach your keyboard and mouse as well. There's little chance that the keyboard or mouse is causing your computer to freeze during the POST but just to be thorough, we should reconnect them while we're reseating other hardware.

Reseat the CPU only if you think that it may have come loose or might not have been properly installed.

Note: I separated out this task only because the chance of a CPU coming loose is slim and because reseating one could actually create a problem if you're not careful. There's no reason to worry as long as you appreciate how sensitive a CPU and its socket/slot on the motherboard is.

Triple check every hardware configuration if you're troubleshooting this problem after a new computer build or after installation of new hardware. Check every jumper and DIP switch, verify that the CPU, memory, and video card you're using is compatible with your motherboard, etc. Rebuild your PC from scratch if necessary.

Important: Do not assume that your motherboard supports certain hardware. Check your motherboard's manual to verify that the hardware you've purchased will work properly.

Note: If you haven't built your own PC or haven't made hardware changes then you can skip this step entirely.

Check for causes of electrical shorts inside your computer. This could be the cause of the problem if your computer freezes during the POST, especially if it does so without a BIOS error message.

Start your PC with essential hardware only. The purpose here is to remove as much hardware as possible while still maintaining your computer's ability to power on.

    If your computer starts normally with only essential hardware installed, proceed to Step 9.
    If your computer still isn't displaying anything on your monitor, proceed to Step 10.

Important: Starting your PC with its minimum necessary hardware is very easy to do, takes no special tools, and could provide you with valuable information. This isn't a step to skip if, after all the steps above, your computer is still freezing during the POST.

Reinstall each piece of hardware that you removed in Step 8, one piece at a time, testing your PC after each installation.

Since your computer powered on with only the essential hardware installed, those parts must working properly. This means that one of the hardware components you removed is causing your computer to not turn on properly. By installing each device back into your computer and testing each time, you'll eventually find the hardware that caused your problem.

Replace the nonfunctioning hardware once you've identified it. See these Hardware Installation Videos for help reinstalling your hardware.

Test your computer's hardware using a Power On Self Test card. If your computer is still freezing during the POST with nothing but essential computer hardware installed, a POST card will help identify which piece of remaining hardware is causing your computer to stop booting.

If you don't already own or are unwilling to buy a POST card, skip to Step 11.

Replace each piece of essential hardware in your PC with an identical or equivalent spare piece of hardware (that you know is working), one component at a time, to determine which piece is causing your computer to stop during the POST. Test after each hardware replacement to determine which component is faulty.

Note: The average computer owner doesn't have a set of working spare computer parts at home or work. If you don't either, my advice is to revisit Step 10. A POST card is very inexpensive and is, in general and in my opinion, a smarter approach than stocking spare computer parts.

Finally, if all else fails, you'll probably need to find professional help from a computer repair service or from your computer manufacturer's technical support.

If you don't have a POST card or spare parts to swap in and out, you're left not knowing which piece of your essential computer hardware is not working. In these cases, you'll have to rely on the help of individuals or companies that do have these tools and resources.
