I have plugged out and in GPU and HDD and now pc is booting normal. Thats odd :(
Have you tried to swap your mobo?
silly me. i didn't mentioned. When I disconnect pc from power, and then connect it again its booting normal. I Don't have another PSU to check it :(
I have no idea what can cause this. If i try turning it off and on again it works. But when im leaving it shuted off for ie. Night, next morning...
