Hey guys, I've just changed changed the PSU and the GPU in a computer and now if I try to boot up the PC, every fan spin (idk about the psu tho') and there is even the little light on the mobo, but, nothing appears on the screen, why? If i remember, I have these specs.

X4 880k
GT 520
300 watts (should be enough tho')
Asus M4A77D
4Go of RAM


What should I check? Thanks in advance!

Check your ram and turn off your pc for few minutes and remove the ram and after doing this put the ram back in its place and start your pc.
