fixed (was Oh crap, help me w/a scrambled L7S7A2!)

[Cerb]

The board is an ECS L7S7A2. It was working until maybe half an hour ago. It has had the following video cards (in order):
Vanta
Radeon 9600XT
GF4 Ti 4200
GF4MX 420SE
Savage IX
Radeon 7?00 AIW

The search was for a card that would use its TV outs on boot. However, somewhere along the way, the motherboard got all confused. It now shows the Energy Star logo, mobo name, BIOS revision, and says "Checking NVRAM." It sopped giving POST beeps I think with the Savage.

I've reset the CMOS, reset the CMOS and hit power while in the reset position, tried a different PSU, different video cards. No other things than video card and RAM are plugged in. About half the time, it will boot like this with the HDD light on solid. It also attempts to reboot when I hold the power button to turn it off, so I actually have to turn off the PSU to do that.

Any ideas?

Sounds like you knocked an IDE cable half out of its socket. That's a pretty common accident when you keep plugging and unplugging other stuff.

While you're at it, check everything in sockets and slots for whether it's still properly seated too.

There were no IDE cables attached to the mobo.

Letting it boot with the AIW but without a video output got it to POST, eventually.

For a few months I had a similar problem. I would mess around in my case and then go to boot up resulting in the HDD light would staying on and no post. It was hit and miss too. Then by accident I found that my freakin power connector to the mobo was loose, and whenever I was I was messing around in the case, I was either pushing it in just enough or pulling it out just enough to make my day hell Snapped that sucker into place, no more probs. Sucha noob
