I have run into a very interesting, not to mention frustrating issue when trying to start up windows. It all started when I was transporting my pc in the back seat of my car. It may have gotten bumped around a little. Now when I try to start it up, it goes through the bios ok and will allow me to enter setup. When I continue through to start windows, it will display the windows loading screen, then when it should load windows the screen just goes blank. The monitor displays the "no input source" message and the green light turns orange (on the monitor). My pc will continue to run, and I even will continue to hear activity coming from the hard drive. Right when this issue happens I hear a humming that is a little louder than usual coming from either the hard drive or the video card (I think it is the video card). One thing that worries me is that even though the fan on the video card is still operative, the video card is very hot to the touch. I fear that there must be some problem with my video card. Does anyone have any ideas why it might be overheating? Any other ideas? Thank you for the help.
