I installed windows98 over win95 and it was running fine. Now when I try to boot to windows98 it gets to the desk top but will not load the icons. An error message comes up telling me that an illegal operation has been perfomed. I have tired to run a through scan disk from safe mode and it will only complete about 7% and then hangs. This happens every time. Also sometimes when I try to boot, cpu will check A drive and hang there. Any help would be appreciated.

Thanks
