Thanks...sorry for the delay...I have a nvidia 8600gt...I plugged out the video card and plugged the monitor into the VGA port from my mother board and was able to get the monitor on. When the desktop powered up I got a 0xc0000411 hibernation error. I was able to then get to the log on screen and delete the hibernation file. However when I plug the video card back in I'm back to no response. It looks like maybe it's the video card and not the PSU...thoughts?
