Last week my cd-rom wouldn't work if windows was loaded. Next my monitor wouldn't work in windows. I gave up and deleted win.com and reinstalled windows98. It worked fine for about a week and now my 3.5 won't work unless I boot up with a 3.5 disk or hit F8 and select command prompt only. Windows device manager and all else says everything is fine but when you go to dos or my computer and try to access drive "A", the 3.5, you get a device not ready error or in dos (through windows) you get a device not found error. Microsoft had no solution. Also my virus checker, Dr. Solomon, doesn't work either. All this may be related.
