New PSU = no image

Hi forum
I recently updated my psu from 500 to 650 due to quietness reasons. Although I properly know how to change it something has happen that I can't explain.
The computer boots, with both CPU and gpu fans starting. Although sometimes it takes a 2-6 second "rest"(with everything turning off again) to then start, just a couple of seconds in the start, that has never happen before.
As it then starts there is no image on my screen, since I have a hd6970 that has a light that tells me if something is wrong, it's not the gpu. The USB ports doesn't seen to be responsiven since the keyboard dosnt light up, although my headset is showing that is being charged, so clearly power is going trough( I have tried all the USB ports and they all charge)
So now Im stuck I have no idea what to do
Please forum, help

Sincerely Adam
