Think it is psu problem?

[SigGod]

Hello, when I power on my system all the case fans and LEDs light up cpu fan spins fine hdd light, lights up, but nothing on the display adn gpu fan is not spinning. Tried gpu in another comp and works fine, so its not that? Could it be psu even though it powers motherboard and cpu fine?

it sounds like it could be a motherboard/cpu issue....do you have another psu you can try to rule that out? you should remove all of the cables from your motherboard except for cpu and mobo power and keyboard and try to boot into the BIOS.....if that doesnt work it is either a cpu issue or a mobo issue. then if you can try putting the cpu in a different board and see if it works you can rule out either the mobo or the cpu

I had a 650i that blew capacitors a couple of years ago. Look a the capacitors and check to see if any are bulging...

You may be lucky as some of those boards used all solid caps...
