win 8 upgrade.

[shiva]

ok guys I probably screwed this up so I need some help fixing it. I upgraded a i7 box to win 8. everything was going well and it was running. I had downloaded boinc and was getting drivers for the video card. I had left it and wet to do some other stuff. I turned around and win was restarting I didn't know why as the last I saw it was installing the video drivers. I went on and left it for about an hour and it was still trying to start. I finely shut it down and rebooted it. now it will not start. I can't even get it to do anything but light the mb up, nothing to the video. the only thing I have left to try is resetting the cmos. any other ideas.
thanks for any help

Can you yank the GPU and put in something else (or nothing, if you have onboard video)? I'd guess something screwed up with the driver.

sure can, will do that.

nope at least is is still no putting out any video. the post port debug led is continually running though. it never stops and I know it should.
