I was using my computer that i had built myself. It was just like all the other hundred days i had been using it, I had one the sides off my computer off when I to went to put it back on then, bam, the computer turned off and won't turn back on. I have tried several sockets around my house by it just won't turn back on. Please help! I have found that if I plug the power cable in then remove it after about 10 to 20 seconds the fan and lights flick on for less than a second! Please help me and thanks in advance any advice
