Win 2000 Boot Problems

Need advice on troubleshooting Win2000

Running a PC dualbooting 98 and 2000

Just after installing 2000 and motherboard drivers, installed, and add-on component (it's only 0.1 MB to install) will supports Fronpage extensions and other web basedapplication. off the cd

then 2000 began hanging during startup. It will boot right up in safe mode.

I need some suggestions for diagnosing and solving the problem short of Reinstalling 2000 (which takes too long!)
