e-machine turns off and on

Specs: Windows XP
My computer turns on, runs for a couple of hours then the screen appears that says computer is shutting down. it then restarts and does this over and over again. I have replaced the power supply, changed the ram. Disconnected each component one at a time. All fans work. No visible blown capacitors.

If it's warning you before shutdown, then that's quite likely virus/malware issues---not hardware. It'd be a big help if you could post exactly what it states before shutdown...

It simply states windows is now shutting down, just as if I shut it down normally. Then it restarts. After several times it just shuts off and on with our fully booting.

Also, If you are not up on system maintenance, you might want to do some cleaning out. Clean out cookies, browser history, temp internet files etc. (manually through your browser's tools), then do a disk clean up (recovers that area plus others). Check add/remove programs for anything not yours or no longer needed. Do a disk defrag and then do a windows update. These things if you are behind enough on will effect your system to the point of triggering a restart, especially added together and it definitely will not hurt.

All of the above, disk clean ups and maintenance tasks, have been preformed. Windows update has also been done. Will a complete format and new install take care of a virus if one exists? Or do I need a new hard drive?

let us know if the format works for you - although to me this sounds like the computer is overheating, and shutting down to prevent damage (only certian computers do this)

If this is the case, just get a can of compressed air and blast the dust off of any heatsinks in the computer

I have already cleaned all components on the mother board to include the heatsink. Also removed cleaned off and applied new thermal paste to bottom of heatsink. I have a small spare hdd I am going to format and try first before I format the original one just to be sure.
