You would get better results by listing your exact hardware. Not knowing whether you have a Geforce2 or 3 is a bit worrisome

There may be something specific about the config you're running that causes a problem.
This is the order I do things in and my system is quite stable:

2. FDISK and FORMAT hd.
2a.Install Win2k.
3. Copy driver cd to hd.
