OT-WinXP the Ult. Evil since no discussions involving hell is complete without our friends at MS, I am seeking some serious advice from any XP users out there. Essentially, about 2 nights ago, I noticed that roughly 2 gigs, yes, gigs of space suddenly cleared. The system seemed to continue running fine, I did a virus scan, turned up one spybot, chkdsk, fixed some minor file problems, and couldn't determine what went missing (you'd think 2 gigs would be sorely missed!). Long story short, while trying to determine more of what happened today, lots of file instabilities of the type 'cannot find xyz.exe' even though the file could be found by search and was found on the c-drive. I decided to try a system restore, but again, 'windows can't find the file'...so, I found it manually, and chose 'run-as' and turned off the little security feature, and it opened, then promptly died due to, yup, not finding a dll that a file search did find. so, no system restore. so...how hosed am i? are we talking using restore disks back to pristine (reformat basically), or is there something I'm not finding or don't know (probably a whole bunch)? thanks to anyone who has an idea (and no, i can't buy a mac at this time!
