What do you do if Setup hangs, shuts off your computer, or displays a STOP error (the infamous Blue Screen Of Death)? Here are a few suggestions:
Try again. Sometimes Setup is smart enough to avoid whatever it was that caused the problem in the first place.
Update your BIOS, or disable ACPI. As noted earlier, ACPI is Windows's advanced power-saving technology. To turn it off, at the beginning of text-mode setup, ignore the prompt to press F6 to install third-party storage drivers; press F5 instead, and then select Standard PC from the list that appears.
Try one of the Windows 2000 Help System's Troubleshooters. The Windows 2000 Help menu has some useful suggestions in its System Setup Troubleshooter. (At the desktop, press F1; in the Help window, click Contents; click Troubleshooting and Maintenance; click "Windows 2000 troubleshooters.") On the other hand, this tip is no help if you don't have access to an operating Windows 2000 machine.
Check the Knowledge Base. The definitive source for troubleshooting any Microsoft product is the Knowledge Base at http://search.support.microsoft.com (although once again, you'll need some functioning computer to get online).
