Sounds virussy. Are you able to boot up in safe mode to run a virus check? \n\n(Hit F8 repeatedly during the boot to get the boot menu, and choose safe mode)

Sounds mostly like you will have to flash the bios and/or update it. After wards try it again, it should work fine. Also, I read that someone told you there could be a problem with your USB; THEY'RE WRONG! That will not cause your PC to shut down, it will simply not work properly or not work at all. Good luck.

Hit f8 continually in startup. If you get an option to restore system to previous time accept it. starting up in safe mode should work.

Have you done the regular maintenance stuff? Delete temp files (disc cleanup) and defrag? I would do that first. \nThen I would do another check by going to my computer, right click on C drive, click on tools, then check error checking check now. It won't do it until you restart. If that does not fix your computer then I would do the system restore.\n\nI would also run a spyware program to make sure you are not full of cookies.\n\nGood luck!

Mine did this _ Problem was I hade a card reader hooked up to my USB port and it stopped the computer from finishing the boot - check your USB plug-ins - Hope this helps!

Press the power button for 10 seconds.  That will shut it down hard.   Then restart.   If you have the same problem, trying starting it in safe mode.

Somethings to do will be;\n\nOpen the computer and check all cables and connections\nRemove the CMOS battery to reset the Bios\nDisconnect any hardware that you don't need to boot up\nTake the Ram out and then put it back in\n\nIf none of this helps then it is either a power supply problem or the CPU is blown and the only way to find out which one is to remove it and test it with a working one.

What do you mean by "not start up"? You could try hitting f 8 when booting up (keep hitting f 8). that will take you to a screen where you can start in safe mode. uninstall the video card driver and reboot into normal mode. Then reinstall your driver

Good information to help you resolve this would be:  new or used computer?  It could be shutting down for a multitude of reasons...  The first to come to mind is temperature.  Most motherboards shut down a few degrees before the processor's thermal breakdown point.  You may want to see that your heatsink is seated on the processor properly, and that any and all fans are functioning.\n\nAnother common culprit would be a virus.  Look for a free program that will let you do a boot time scan of your system.

My Computer \nProperties \nAdvanced \nStart Up and Recovery \n-Settings button. \nuncheck "Restart on System failure"\n\nThis will mean that you get a BSOD with an error code - which help identify the cause of the problem

when you first turn on your computer start hitting f1 over and over before it boots up you have to be quick or you will miss the window for the bios setup menu if you do shut down and try again good luck

shutdown the computer by holding in the power button about 30 seconds. there are gears that control the movement of the tray of the cd rom, if it doesnt work after restarting just buy a new one they are not economical to repair

Hmm you might want to do a system restore. It sounds like you got a corrupted drive.\n\nTry going to START then RUN then type msconfig and hit enter. Go to the STARTUP tab. Then you might want to get rid of some startup programs thats conflicting with your computer that loads when your computer boots up. Try and download http://www.avast.com and do a scan on your computer to see whats wrong.\n\nAlso click on My computer and then right click on your C drive and choose the scan option and do a scan on your computer to see what errors might need fixing.\n\nThen just reboot and see if the errors stopped.

You may need to clean it up; try:\nDeleting temp and history.\nRunning clean disk\nRunning Defrag\nClearing your recent files\nEditting the programs that run at start up.

Sounds like a memory problem.\n\nIf you have more than one stick then take them all out in order.\nPlace No2 stick only in slot one and boot, if the problem is still there, then take that stick out and put No one stick only in slot one and boot again.  If at any stage one of these sticks work correctly then the remaining stick was at fault and is the bad one that needs to be replaced.\n\nAlso it could be down to the CPU overheating, try removing the computer case side panels and see if that helps\n...Can you boot into safe mode at all...e-mail me if you can and I will try and continue to help you.\n\nHope this helps you.\n\nGood Luck.\n\nRay
