I don' know when it happened. I was havin trouble defragmenting and i fixed that by trying a few things from microsoft support, which included deleting folders in applog & Quick launch toolbar and then defragmenting in safe modeThat worked and i did'nt notice right away untill i tried to read a cd something was wrong. I went to control panel no more e or d drive Ican't even reinstall cd writer because it will not read. in the systems configuration utility start up not much is checked but i don't see anything that says e or d drive. we also had a power outage when i was on. can i restore what has been elimated without using a recovery disk? I am a real novice at all of this. So please give insructions like you are talking to an idiot. i have a compaq fs740 with win98.
