For the last couple of weeks my PC has begun restarting itself for no apparent reason after being on for a few hours or so. I shut it down and left it down (thinking it may be an overheating issue). Now the PC won't boot up. It runs POST and brings up the Windows loading screen and then restarts itself from there. The OS will not load and I'm not sure what the problem is.

Re: PC won't boot
When you can get it to start, go directly into the bios. Once there find hardware monitor. (if your bios supports that). If so, here you can monitor cpu & motherboard tempture. Just let it sit. If its a heat issue you will be able to see it in the bios. Also lets see if the pc restarts by itself. If no restart takes place I would guess this is a software issue. Possible virus/worm. Pull the system memory & reseat. Reinstall windows.

Your motherboard has a CrashFree Bios2 feature that only supports the VGA output (not DVI). If you connect your monitor to the VGA port and see nothing then you should disconnect power and move the Cmos Ram jumper to Clear position for a few seconds and then restore to the operating position. Then restore power and see if you can enter Bios Setup. If this restores you to a default bios, do not upgrade again until you are certain that the bios version is correct for your chipset, bios manufacturer, etc.
If you computer over heated, this could have caused the board or power supply to short. I would first start by trying a new power supply unit (since this is cheapest of the options). If that does not work then try replacing the motherboard and/or processor. Since you not getting any power, my guess is motherboard or power supply unit.
LEAVINGYOUR COMPUTER RUNING ALL THE TIME WILL NOT MATTER.

SHUT DOWN THE SYSTEM, MAKE SURE EVERYTHING IS SEATED, REMOVE THE MEMORY AND REINSTALL THEM, REMOVE THE CONNECTION FROM THE HHD AND MOTHERBOARD RE INSTALL THEM, REMOVE ADDITIONAL BOARD AND CARDS, UNPLUG MONITOR AND PLUG IT BACK IN, REMOVE ANY EXTRA USB CONNECTIONS UNTIL YOU TRY RESTART THE SYSTEM.
hi sunnyh, when you start up the PC start pressing the F8 key every 2 seconds. A dos like window will load. At the bottom of the list choose, last known good configuration. (win might load the last good configuration) it's worth the try.
If your PC still does not load windows than repeat the above, this time choose, Disable automatic restart on system failure.
This also might allow windows to load (hopefully).
A system that starts going into this restart loop happens for many different reasons. Most common reason was a program that was last installed just before PC was restarted. Second most common reason for restart loop. Added new hardware, bios changes & windows boot files corrupted. If you did install a program, uninstall it. If you were in your bios & made changes, reset the bios. If you flashed the bios, go back to the old bios version. If you added new hardware replace with older hardware.
To fix Windows you may have to reinstall it. Do not run format or you will loose all your data. Even system restore CD's allow for a win reinstall without a format, however if the cd does not allow you to reinstall win unless you do a format. Than windows startup files are too screwed up & you'll have no choice but to format.
All you can do is try the above & cross your fingers.
Unplug the the dsl & any other device except the keyboard & mouse. Double check the video cable at both ends monitor & PC. Boot up system. If the system starts shut down & connect 1 device. Boot the system. OK? continue to do this. On the dsl there is a reset button. With it unpluged from power use a pen & hold in the reset for about ten seconds. Reconnect the power & reconnect the Rj45 to the PC. Boot system.
