PC won’t boot except Safe Mode

I have a Quantex Celeron 500 running Win98SE that will not boot except to safe mode. A normal boot will just freeze after a few seconds. The interesting thing is that I have tried several hard drives that have Win95, and they exhibit the same behavior, even the bootlog.txt looks the same. I have removed the network card and modem and put in a different video card without help. Reloading 98 didn’t work either.
