Got this machine that I used to never have any problems with. I would have it running 24/7. Suddenly, about a month ago, the machine would shut itself down after an hour of use.

So what did I do? I checked to see if all fans were running but that wasn't the issue. After doing that, I checked to see if it were some settings. I haven't cleaned the machine in awhile so I decided to just do a format and get to a clean state since I wasn't sure if I had tinkered with some setting beforehand.

By the way, when I say shut down, the machine itself doesn't just turn off. The discs continue to run but Windows isn't in hibernation / standby mode. I have to manually turn it off. I decided to just check temps in BIOS but nothing is out of the ordinary. I also checked to see if it was some power management issue but I have everything set to "never" because I use this machine to store movies, games, etc. I also don't have hibernation mode enabled.

At this point, I don't know what else to do. If you have any ideas, please let me know. Thank you for your time.

Could be the power supply. Try swapping it out if you have another one laying around.

Is the computer an E-Machine by any chance? I've seen that same sort of situation twice before on E-Machine desktops I was working on and both times it was the motherboard. It seems to be a fairly common and well known issue with them. They had a bad series of motherboards they used for some time (years?) and basically the motherboard has to be replaced.

A motherobard problem is often a hard problem to pinpoint because short of installing a new mobo, there isn't much you can do to figure it out. It is a very time consuming and even costly process to replace every single piece of hardware one piece at a time to determine what is causing the problem.

From my experience, without looking at it myself, I'd say a power supply, motherboard or the processor over heating would my first guess. Then again, you can't rule out a bad stick of RAM but it's pretty easily tested.
