Troubleshooting help.

[msparish]

I have an older computer (Athlon XP 2500+, 1Gig Ram, etc.). Recently, it has been having some trouble booting up. It would boot for a few seconds, reset, stay on a few seconds, reset, and so on. Once it got into Windows it was stable. I had seen this problem before and it was the Power Supply.

Starting yesterday when I turn it on, it doesn't do anything. The fans turn on, but nothing comes on the monitor, no beeps, or anything. I tried switching out the Power Supply, but it did nothing to help.

Any other ideas on what the problem could be? I've been toying with getting a new rig, so if it's going to be too much trouble to troubleshoot/fix, I'll just do that. However, if I can easily figure this out, I can get a few more months out of this computer.

Thanks for any help!

Take it completely apart, except for PSU, processor, and one ram stick (obviously you'll want to keep the HSF). Try booting. If it works, gradually add components until it fails. Voila! You'll know what the culprit is. If it doesn't work at all, you know it's mobo, memory, processor, or PSU. that's when you need to borrow someone else's stuff and put it in to see what's wrong.
