I recently built a desktop and when everything had been plugged into place the first time I pressed the power button it showed life for half a second and then turned off. I have tried reseating my CPU, changing the location of my ram, using 1 stick of ram, and reseating cables on my motherboard. If I unplug my CPU power cable from my motherboard the computer will turn on and stay on but is unusable. Is there a quick fix to this problem and if not what steps should I take to minimize the cost of repairing/replacing?
