Windows 98 Startup Problem - Explorer has performed an illegal operation

Hello,
A friend (not local) is having problems booting up into Windows.  He is running Windows 98 and when his computer is first booting into Windows he is receiving an illegal operation error with Explorer (Explorer itself, not IE).  Once he acknowledges that error it just goes to the green background with no icons or anything.  He is unable to boot into Safe mode.  He does have a boot disk that can boot him into DOS with CD-Rom support.  He is a very novice computer user so step by step directions would be needed.  Thanks!

Thanks!  I will get him to try this.
Hi Adrian,

If ScanReg doesn't work then his best bet would be to reinstall Windows 98 over the top of his current installation.

It's easy, you just boot off the CD-ROM into Windows setup and choose the option not to format.

It'll replace pretty much the entire contents of the C:\Winodws directory and it wont touch the registry or uninstall any of his programs.

With Windows 98 this is usually the best option.

-Edit
It  may be necessary to rename win.com to win.old before he can reinstall over top (the file is in c:\windows).

this is guaranteed to clear his system to he lowest possibile level , even the fat tables that arent cleared by normal format
NOTE to 2000/XP users: command exists but those oses dont allow hardware writes so you will get an error at the end
Thanks everyone!  I will have him try out all these potential issues and get back to you.  I (and he!) appreciate it!
