I recently had the exact same problem after doing a hard drive upgrade.
Turns out it was an incompatibility between the motherboard (shuttle) and
the new hard drive (ultra DMA-33).  I changed the motherboard (to a IWILL TX
chipset - Which by the way is fully supported by win98, not so with
win95b{needed patch}, and the problem went away.

Hope that helps.
