Well, have you ever cleaned out the dust inside your computer? I have to ask this becuase a lot of people don't know you have to do this every once in a while. Dust can cause overheating problems, and other issues. If your PC is clean on the inside, then I would check out your RAM. It is possible to have a stick going bad, or bad and causing it to freeze up. Next would be the condition of your HDD where your OS is.

Does your PC run slow when it is working? Have you defraged it lately? Maybe run a scan disk on it. It is possible for a HDD to start having issues and causing your computer to act up. I had a system running 98SE and I forgot to clean out the dust for almost 9 months, so after it was on for about 30+min it would start to act up, lock up on me, and even reboot. It was the HDD had to much dust in and around it. I was lucky, I cleaned it, and saved my drive.

That's about all I know of right now. Good luck.
