Ok, through the past 5 or so days i've been having trouble with my computer, it started with an update to SP3 from SP2 to fix a bug with a game (another story). After I did this, I got an unmountable boot volume crash, to check if my HDD was dead I installed linux, everything was working fine, I then installed XP SP3 again from disc, it works fine for the first day, then the 2nd day the PC suddenly becomes very sluggish and eventually I need to restart it. The first time I restarted I got a 7A BSOD and couldn't get back into the PC. So, I formatted and reinstalled again, then again it became sluggish and I eventually restarted, this time though I got an error saying System32/System is missing or corrupt. I'm now going to try and repair it through the recovery console and see what happens. I can't get the minidumps since I've formatted the computer since I couldn't get back into it. EDIT: Ok, the 2nd line of help from MS to recover the registry doesn't work, I'm meant to type "copy c:\windows\system32\config\system ", I get the response, "could not copy", great. Does anybody know what could cause these errors/what I could do to solve them?
