Custom Computer Problem

[Falcon]

When i start up my custom computer that ive had running for over a year now, it turns on, all the fans start up and everything and then a few seconds later it just shuts off. What hardware is causing this. Is there any way to narrow down to what i need to do. any suggestions would help. thanks

Have you checked your case and motherboard to make sure they're not touching somewhere, thus causing a short? You could also take the parts out of the case and put it together on a piece of cardboard or something to make sure that that's not the problem.

If you have another PSU, you can throw that in and see if it works.

After that, you could unplug everything down to barebones (CPU+RAM+somethingIdontremember, I think anyway) and then hook it back up one at a time.

Well, i bought a new power supply and everything seems to be working for now. We'll see how long this one lasts. Thanks for your help.
