WELCOME TO THE FORUMS, MULL...
Have you gone to the Windows Update page and done all your updates?? There should be several updates there dealing with shutdown problems in Win 98...
You should also check and make sure you have all the latest drivers for you system and if all else fails, you can reload Win98 and see if that doesn't solve your problem...Good luck and keep us posted on how it goes...
Another possibility is to go to:
Programs>Accessories>System Tools>System Information>Tools>
System Config. Utility>Advanced>and Disable Fast Shutdown...
It may help and it may not...
Don't Give Up The Ship...
