As the title says, I just built a brand new high end system. It was up and running over a week then I got home from work one day and it was off. I turned it back on and it just went off again after about 5 minutes, then wouldn't come back on. I opened up the case and saw that when I pushed the power button, the fans and lights came on but no video and no post.
As I understand it, it's either the power supply (lack of power), bad motherboard or bad cpu. I don't have too many spare parts laying around so please advise how I can narrow down on what the problem is.
