For some odd reason, my computer will now no longer power on at all. When I push the power button, the motherboard beeps once and nothing turns on but the power led; not the fans or lights. This began to happen just today. For the last few weeks, my computer has been auto-shutting down because it gets hotter than the failsafe temp I have set in my BIOS. Today, I was on it for 15 min when it auto shut down again. I tried to boot it when the above happened. However, I was still able to boot it after a few tries. It then shut down again and then it wouldn't come back on.

I have tried everything I can think of. I unplugged all of the power cables and re-plugged them in. I pulled out the RAM and video card and put them back in. I tried a new power cord. I cannot figure out what the problem. I wanted to test different components so I could see what the problem is, but I unfortuneately don't have any extra parts to test it with. I was just wondering if anyone had any ideas what the problem is. Is one of my parts fried? Or, is there some easy solution I don't know of or can't figure out? Any help would be greatly apprectiated!

By the way, I have a GeForce 6800, a GB of RAM, 200 GB hard drive, and am running a duel boot with Windows Vista and Windows XP.
