Hi all, my daughter asked me to look at a fairly old (3-4 years) Compaq desktop I gave her. When the PC starts the monitor comes up with the Compaq logo splash screen but will not enter the Windows boot process. Even though the screen states you can enter F1 and F10 for setup and recovery respectively these keystrokes don't do anything, it does not seem to be entering the Windows boot process where (maybe) I might be able to troubleshoot. I removed the side panel, and cleaned the PC (the dust and cathair was incredible). I also tried exchanging the Lithium battery based on a suggestion I saw for a similar problem, still nothing. Any ideas where the problem might lie? Could this be the video card? I checked the keyboard on another PC so I know that is working, I assume since the monitor displays the Compaq logo that the problem isn't with that. Any ideas would be appreciated.
