I am working on a Dell Dimension 8400 running Windows XP. Earlier yesterday we were suddenly unable to access resources on this computer (shared files and folders) via our small peer-to-peer network. Upon re-booting the computer it would hang at the Windows XP logo screen, while the blue bar was scrolling across. After waiting a period of time, I powered the machine down by holding in the power button. Upon rebooting I hit F8 and selected "Safe Mode", and the computer stalls at the same point each time I try to boot to safe mode. It stalls at windows/system32/drivers/agpCPQ.sys.
From reading some of the posts to the Experts Exchange, I found out this file may or may not be the source of the problem. To my knowledge no new software has been installed recently and the computer had up-to-date virus definition files running.
One other point of interest, when I try to use the Windows XP Recovery Console, it seems it cannot find the Windows directory. Instead of getting a C:\Windows prompt, I simply get a C:\ prompt. Then I remembered that the Windows installation is on a 4 GB partition called G: (this is how it came from the factory). So when I try to go to the G:\Windows directory I get an error that the path does not exist. If a try to view the directory structure using 'Dir' I get an error that says "the directory stucture could not be enumerated"?? If anyone has any thoughts about how I can proceed here, my goal is to hopefully get this machine up and running withouth re-installing XP or re-formatting. Since you are probably wondering, yes...we have a good backup of the drive from the night before, but the software on this machine is a real pain to re-install.
