Hi, This involves a Pent 4 1.8 GHz Dell PC that is running W2K. When you power up, if the monitor warms up in time, you see the "DOS" screen (ASCII Text) what shows the B&W progress bar at the bottom that says "Windows starting".
Then the normal Windows spash screen shows telling you that Windows is starting up. Normally at this point I would expect the screen to change and a message box to show that displays various things that the OS is doing as it starts up. However on this system what happens (and just started happening this AM) is that the middle of the Windows Starting Up splash screen turns into a sort of DOS window and some messages show that inform you that the "Type of File System is Fat32" and that is is going to check the file structure on the C: drive in 10 seconds.
If I let it run its course it does a chkdisk on the drive and then continues to boot in a normal manner until it gives you the blue screen of death.
If I hit a key during the chkdisk countdown, thus preventing it, it'll boot normally and it'll be useable.
I've checked the BIOS menu and there wasn't anything that mentioned the type of file system on the PC.
PS Would you believe it? Next week I'm scheduled to go to a week long class on supporting W2K PCs/Servers...
