Oh, i know that problem. When this happens, press the start button. So manually shut off your computer. Then turn it on, this will stop it from occuring over and over.
Im not completely sure why windows 98 does this, but it happened alot to me. It only happened when i had to many applications going or something loaded wrong. So im pretty positive it only happens when your computer frezzes. But if it dont occur 90% of the time, related to why it happened to me, then call your Tech Support. yeah that should be fun, freaking tech support.
