Its something with redhat does it do a hardware scan like windows does?
Well JayCnrs claims there's some 'kudzu' thingy...I guess you could check that out. The problem is that if this is linux related, you'll need to boot linux to fix it.
So have you tried to boot with a linux bootdisk? Get a minimum linux boot disk and boot into single user mode. This way, many of the stuff will probably not be started. if that doesn't work, get a linux boot disk with a kernel installed (such as tomsrtbt floppy) and see if you can boot a minimum linux (you can mount the HD afterward). if even this does not work, look for a hardware problem/conflict.
BTW, JayCnrs : color and HUGE fonts are bad. They hurt your eyes and make you squeal. I've always tried to persuade by content instead of flashy looks. But then, I'm just cr@zy.
