I was installing my 8800gts yesterday and after having a few issues with detecting my Raid array i finally figured out that I had accidentally unplugged the power to one of the hdd's. Anyways, I plugged that back in along with my gts and powered on. It worked fine initially and made into bios, where my mobo was able to detect my raid array. Assuming myself done with tinkering, I closed my case up (put the side on), and at about the instant I put it into place, my computer lost power and died, and would not power up again. At first I thought maybe I jostled some power connection, but this doesn't seem to be the case. When I plug in the power cord and turn on the PSU, everything flashes on and off for a splitsecond, including my CPU fan and gts, but this has happened for as long as I've had the computer. I tested the PSU and that still works fine, and so does the CPU. I'm pretty sure the RAM isn't the issue, and it definitely isn't the card. I thought the power button might have gotten disconnected but I don't think that's it either. I'm pretty sure my mobo just died flat out, I just wanted some way to confirm this before I go out and buy a new one.
Oh, and also when I plug in the power cord and turn on the PSU the little green light on the mobo turns on.
