Computer Does not Boot correctly, Monitor is Black.
Very interesting...Might try the following...
- Video. Yes, almost garuntee that it is either the video card/onboard or the cable. Look at the cable and cable connectors and see if one of the pins has been shoved in. This is common. Often, one will replace the cable and still have the problem because a pin has been shoved in on the mother board.
- Power. Remove everything from your computer except the keyboard and the monitor (yes, even the mouse) to eliminate any power drain issues. If you can, remove the DVD drive (unplug power and data bus cable).
- BIOS. One beep is good. You should be able to get into the BIOS setup no mater what other problems you are having. The BIOS uses a generic text, video and keyboard driver. If you aren't able to see ANYTHING after the beep then it is definately the route from the motherboard through the video card or onboard video, through the cable to the screen. You seem to be going through the right steps to debug but just haven't found it yet because it is something that you have dismissed as working...like the pins on the video connector. Go through your path again, this time look at anything that you have assumed that was working and suspect it as the issue.
