Had this computer for a few weeks put a gts450 in it when I got it. It was running fine no problems at all, now one day I try to turn it on and nothing. No beep no fans nothing. Only mobo led when psu plugged in. It was a very bad psu so I thought it was that, since then purchased a new 500w psu, after putting that in its the same , mobo led but nothing else, my next plan of action would be to test it out mobo CPU psu only on cardboard or something as I've tried it in the case with only CPU mobo and psu and its the same, I've also tried with a flathead to the power sw pins so I don't think it's the switch.

Mobo: asus p8h61m lx3 r2
CPU: i5 3470 ( I think )


If anyone can help me out that would be awesome
