It is a program that restarts your computer. It sounds like you may have a corrupted program on your computer that is causing the problem. This happens for many reasons . It happens most often during reloading of programs and may have happened at the factory. No way of knowing for sure.
I would suggest doing a systems restore. This should be already on your computer.
If you do not know how, contact your ISP or computer manufacturer and hey will instruct you on what to do. Your computer should me under warrantee and while it is this service should be free.
ANSWER:
Let's ask a few questions before we can isolate the issue. First, how long have you owned your computer? (Is it new? Have you had it for a few years? Have you been doing your updates as they come in?) Second, did you add new hardware? (if you did, was it a communications device? IE: network card, wireless card, modem.) And further, did you use a PCI slot that wasn't the last in the chain? (The very bottom of the board, or close to the video card?) And lastly, did you install a new memory stick?
Now, let's address each of these things.
The most current updates that can, and have regularly, caused the issue you describe are the service updates, or "service packs" for Windows XP Pro or Home. (Mostly SP2) The registry and MBR (Master Boot Record) are not re activated correctly due to a bad downloaded .EXE) In this case, there is only one thing to do. You must remove or uninstall the service pack. Both, SP2 and SP3 have an uninstall program, and it can be performed through the "Add/Remove" tab in the "Control Panel" Since the computer won't boot beyond the initial bios start-up, then you will need to keep your finger at the ready to hit F8 so you can enter "safe mode" (pressing the F8 key on your keyboard repeatedly during the bios startup.) If you are successful, then navigate your way to the Control Panel and then to the Add/Remove tab. simply remove the service pack, and reboot the computer. The original condition should be achieved at this point, and you can try to let the Update site try again, or, you could just go to the Microsoft website and download the service pack manually. Because of the length of the instructions, go to: http://support.microsoft.com/kb/875350 Here you will find the instructions to help you remove the SP in several different ways. (I recommend you go straight to the last one since you can't boot into windows.)
In summery, there are several things that could cause the issues you have described. Check each one, and see if any of the suggestions mentioned here, could be a resolution. At the last ends, take your computer to a qualified technician, and have them fix it for you.
It could be sevral diffrent things.. such as corrupted driver or software... the most common cause i have found is a bad expansion card (usually PCI),, or check your RAM.
If you are talking about computer fans, then BIOS should have it. To get to BIOS, you must restart your computer, then before windows starts up (during POST) press 'Del' repeatedly.
You restart your computer and press f8 before windows boots.Select "safe mode".Once your in safe mode find or type your username and password.Your docs should be in your user account.
go to control panel. --> network connections... --> remove windows logon from there.. and restart the computer
You can usually fix the 9c47 error code by uninstalling IE, restart the computer, and download IE from Microsoft. Disconnect the Internet before you run the installer file. Once installed, restart the computer.
A good way to check to make sure the computer registry was restored is to restart the computer. If the registry was restored, the computer will restart with no problems. If the computer shows a screen that offers the user a choice of options like restart normally or restart in safe mode, there could be a problem in the registry that the computer needs to fix before restarting.
You have to restart the computer, before Windows starts press F8 - the best technique is to press F8 repeatedly. You should get a menu including an option to boot in safe mode.
turn on your firewall before connecting to the internet. That should fix the problem. It's an old virus
Restart your computer and a soon as Windows starts loading, press F8. There should be numerous options including one that says something like, "Safe Mode with Command Prompt." Arrow down to that option and press enter.
you must keep trying or restart your computer. (It happened to me before)
Restart your computer and start pressing the F8 key on your keyboard. You need to press F8 before the Windows logo appears. If the Windows logo appears, you need to try again by waiting until the Windows logon prompt appears, and then shutting down and restarting your computer. Note: On a computer that is configured for booting to multiple operating systems, you can press the F8 key when the Boot Menu appears
restart your computer
Hold down the Windows key on your keyboard and tap the R key. This opens the Run box. Type in "cmd" and hit Enter. This opens the Command Line window. Type in "shutdown -r -t 00". Your computer will restart immediately. Leave off the "-t 00" if you want it to wait 30 seconds before restarting. Use "shutdown -s" to shutdown fully instead of just restart. Or you can use the "shutdown -l" option to logoff.
