My problems seemed to start last night. I had a "USB malfunction" which caused me to be unable to move my mouse. I switched to another port and all was fine. Then this morning I go to turn on my computer and it boots for a second, then it seems to turn on and off really quick. I can tell from my LED fans, they flicker on and off. I've tested different PSUs in this machine, none worked. Tested my PSU in another machine, it worked. I tried plugging it into another jack, no dice. I unplugged everything besides the CPU, RAM, video card and it still did the same thing. I've come to the conclusion that it must be the motherboard or the processor, but it seems like it would have to be the motherboard because the processor wouldn't cause the flickering. Did I leave anything out? I have a hard time believing that it would just randomly stop working on me. Any suggestions?
