Ive built my computer about a year ago and have had no serious problems except for now. I was downloading the pictures from my digital camera to my computer when it just randomly shut down. After it shut down, i unplugged my camera and tried to boot it up but nothing happened at all. So i unplugged it from the wall and waited about 30 minutes and when i plugged it in again 2 of my fans start spinning even though the computer is turned off. I tested to see if it was a power supply problem by hooking up a different power supply, but when i do that, nothing happens, nothing works at all. I took my mobo out of the case to see if there was a short but i didnt see anything and i plugged in the mobo to both of the power supplies and all that happend is that when i pressed my power button, the cpu fan spun for 2 seconds then stopped and did nothing when i pressed the power button again. Any help would be greatly appreciated.
