Got it posting fine, loading into Windows 7 fine, all drivers installed etc etc.
with the onboard video
The moment I plug a card into the PCIe slot, it gives me no video. It appears to boot ok, the keyboard lights up and drives act like it's booting and then waiting for me to log in, but nothing. I have the latest Forceware drivers on the system, so it shouldn't be a weird driver issue.
The onboard video will not work either if there's another card plugged in.
I have tried forcing the video to default to onboard, no changes. VGA is disabled by default.
I've tried both my old video card and a new one.
Side note, even with this power supply, when I boot the PC there's a noticble drain on fans and lights in the case. I've seen other builds almost exactly like mine running 850w, I really didn't think power would be an option?
