Video card making my machine unbootable?

The other day, my desktop suddenly shut down. Pressing the power and reset buttons did nothing to make it start up again. Oddly, the power LED remained on. Yanked the plug, let it sit for a while, plugged it back in, and tried again. Nothing. Not even the fans came on. The motherboard light and the NIC light still come on when I plug it in, though. No power LED anymore, though.

Bought a new power supply today, thinking that was the problem. While hooking it up, I decided to test it with just the motherboard connected to the PSU. Fans came on right away. Unplugged it, hooked up everything else, then the same problem comes back. Decide to start unplugging one connection at a time to narrow it down; I tried the video card first. After disconnecting the video card from the PSU, fans came up as normal.

Is it really a bad video card causing my problems, or could it be something else?

For reference:

Motherboard: Intel DP35DP
CPU: Intel Core 2 Duo Q6600
Video card: GeForce 9800 GT
Old PSU: SilverStone DA650
New PSU: Corsair TX550M

(Yes, my machine is a few years old.)

Thanks!

I have had a couple cards go bad. From what I recall they didn't interfere with the fans spinning, but I guess it's possible, especially if all the fans are connect to the motherboard. It would also depend on where on the card the problem lies, I would imagine. Hopefully it is just the card, and not the slot. Most likely, it's just the card.

Well, I just hooked my old PSU back up with only the mobo connected, and the fans spun up, so at least my old one works as well as the new one. Now I know I can return the new one and put the money into a new video card.

Edit: Yeah, it was the video card. Got me a GTX 560 (at a nice discount thanks to Best Buy misspelling their price), and it's alive! ALIVE!!
