Hi Folks, This is so weird I hardly know where to start. I logged off Saturday night and everything was fine. I logged on Sunday morning and all my files, pictures, music, wallpaper, etc. was just gone. I've since discovered that McAfee may have caused it. For those with similar problem; the McAfee Event Log says, "12-14-2008, 6:19AM- System Guard allowed a change to your computer". I logged around 9AM so I'm guessing this has something to do with it. McAfee's tech support was totally useless. So was ATT's and Dell's. In the meantime, a cool guy in one of Microsoft's Newsgroups told me about the "Run C:\Documents and Settings\Old_Username Folder" utility. It revealed a list of my missing documents so I know they're still on the Drive. Now, for the real dirty low down: System Restore keeps saying it can't restore my computer to any point before this thing happened. Wouldn't work in either Normal or Safe modes. (by the way, for those having trouble getting XP to go to Safe Mode I'll put something in a different thread about a solution to that) When I re-boot I keep getting "Primary Disk Drive not found, Secondary Disk Drive not found". I have to hit F1 which takes me back to this empty landscape wallpaper I never saw before this happened. Does anyone here know if using the Create New User Account, then Copy Old Data to New User Account utility will solve this? I have a Dell Optiplex GX240 running Windows XP Professional. I bought this machine second-hand so I don't have a Setup Disc or anything like that. And those clowns at Dell wouldn't send me a User Manual. Will really appreciate any help you can offer.
