Replaced a Pentium II 266MHz CPU with a secondhand Pentium II 400MHz on Supermicro P6SBA motherboard with 128MB PC100 RAM. Changed bus speed to 100MHz from 66MHz. Runs DOS programs OK, but keeps resetting when loading Windows 98. Ran DOS CPU and memory testing utilities, and both reported fault-free.
Old 266MHz processor works fine. Is there any reason why a CPU which works in DOS may not work in Windows?
