Here's a MS KB article on the subject which suggests a BIOS problem. Article ID: Q188308 http://support.microsoft.com/support/kb/articles/Q188/3/08.ASP?LNG=ENG&SA=PE R **************************************************************************** *********8 Subject: [PCBUILD] "Add new Hardware" problems Whenever I try to use "Add New Hardware" I get a "blue screen" and have to reboot the computer. This started happening after I had to remove an Adaptec AH154 card from the computer temporarily to install another card. The Adaptec card was for use by a CDR. Now I'm trying to reinstall the Adaptec card and this problem has begun. I can't even run "Add New Hardware" to detect ANYTHING now. I rerun WIN98SE install and still have the same problem.
