My computer has 3 hard drives with 3 different OSs. My C drive is the one I'm having the problem with.
Anyhow, the other major problem is that my C drive with XP Pro won't boot. I rarely use this drive; usually only to burn CDs or make CD labels with a program I have installed on it. The other night when I did this it was running VERY slow; the printer even took several minutes to start up once I hit print and when it did the computer would almost freeze. I just figured it needed a reboot and it was the only time I had this problem. Well this morning I tried booting into XP Pro and after the initial screen that comes up that says Windows XP with the thing loading below it, the screen just went completely blank and the OS would not boot. After rebooting once or twice to no avail, I think I eventually got a blue screen with the error "Unmountable_boot_volume." I think it was here I first went into the recovery and replaced a few startup files. When this didn't work I went back and did a "CHKDISK /R" which would not go past 51%, though "CHKDISK /P" would finish. Anyhow, after this I try rebooting again and eventually get the message that my c:\windows\system32\config\system was somehow missing. I went to http://support.microsoft.com/kb/307545 and have followed those instructions several times. The first time I was able to boot using the recovery files but I did not have any backup registry files to use unfortunately, except one set from last September but it would not boot with them. The machine did boot after using the original registry recovery files the first time, but after switching to my saved copies of the existing ones and the one set I had backed up the machine would not boot. I then tried to boot it with the original registry files again and now it won't boot. I'm really at a loss here. I very rarely use this drive and don't know why it would out of the blue just stop working. I don't know where to go from here. I'm thinking it's not virus related but who knows (so sorry if this is in the wrong section); the sudden corruption of these files makes no sense to me. Any suggestions? Thanks!
