Hello, I have been having this problem for 2 months now, I tried unplugging every component and nothing has helped I have a CX750M 750 WATT PSU so I dont think that would be the problem. But it keeps on doing the same thing, turning on for about a couple seconds then turning off, when I turn it on the second time it fully works and runs like it had no problem. I have randomly started to get this problem 2 months ago and I have been using the same specs since December and I have had no problems in the months before. If anyone knows what may be wrong please let me know! Thanks!
