No Video Signal

My PC just shut down. Then restarted with no video signal. I put in a new video card, a 8800 GT, and no video signal. Then, I put in a new power supply, still no signal.

What other reasons can a PC not put out a video signal? The monitor is fine. I'm using it right now.

I took off the hard drives, still no signal. I reseated, and even tried moving it to another PCI-E slot.

Would a broken CPU do this? Motherboard maybe?

are all power connectors to the video card plugged in?

Yep, power connectors are plugged in.

First PSU is a XION 600 Watt PSU

2nd PSU is a PC Power and Cooling Silencer 610 watts
 
The 8800 GT I bought today. I was for sure that it was the videocard that was broken. The same thing had happened a few months ago and it was the videcard that was the culprit.

Maybe I had just bought a bum card?
 
They were working, then all of a sudden, the system rebooted randomly and there was no video signal.

What PC parts would cause for no video signal other than a videocard?
 
I've seen bad: hard drives, optical drives, sound cards, modems, nics, cpu, mb all cause a rig to not output video. Components usually damaged by power surges or nearby lightning strikes. I've replaced a lot of parts for people over the years after thunder storms.
 
What's the basic I can boot up with a video signal to narrow it down? Would I get video signal if I booted without the RAM sticks?
 
You need: cpu (+hsf of course), 1 stick of ram, and vid card.

Also suggest assembling all of this outside of the case. Just momentarily short the 2 pins on the mb for the power switch to start it (wire, small screwdriver).
 
I bought another PSU.

No video signal.

Tried it on another motherboard.

No video signal.

So...it's narrowed down to the CPU.
