Any ideas on something I might have missed would be appreciated Otherwise its time for a new motherboard Of course, I'm not too great with computers, so I feel I might be missing something obvious. I'm guessing there is something wrong with the motherboard. The next thing I tried was swapping the power supply with a known working one. the CPU fan would twitch, the power LED would come on. I then turned the computer on by shorting the power jumpers. The first thing I did was unplug everything from the motherboard, leaving only the CPU attached, the power LED wire, and of course the MB power connector and 12V CPU power connector. OK, so my first reaction was it had to be a problem with either the motherboard or power supply. This cycle of on/off/on/off will continue forever until I either hit the switch on the back of the power supply, OR if I hold down the power button for about 5 seconds. About 2 seconds after I hit the power button, the computer shuts off, and stays off for about 2-3 seconds then it will turn itself back on, but of course only for 2 seconds. Here is what happens when I hit the power switch: the computer starts to power up (power LED lights up, fans start spinning, hard drive starts spinning). My computer has been working wonderfully since I built it sometime in May, until yesterday, when I went to turn it on. I am having a problem with my computer, and while I'm pretty sure the motherboard is to blame, I thought I'd check for input before I buy a new one.
