Err Msg: While initializing device….

I have a Micron Millenia running Win95. When booting the machine I get this error “While initializing device a windows protection error occurred, you need to restart your computer”. When I reboot the PC the second time, no matter what configurationI boot into, I can boot into safe mode. In safe mode I have checked devices – no conflicts or errors. I have been told however that some scanner drivers can cause this and to remove existing scanner drivers. The machine has had Pagekeeper Standard3.0 loaded, but i uninstalled the program and am still getting the error. Ideas regarding the true nature of this problem and ways to troubleshoot would be greatly appreciated.
