Hi! I'm at my wits end about this issue and I'm hoping after several long hours googling message boards and going through cryptic microsoft sites that someone can help me (I've found lots of similar issues but none quite like mine). My computer was running fine until today when I decided to try a repair install of xp to see if it would make my computer recognize both cores of my dual core (Apart from this my computer was running like a dream). After said repair install I now get a bsod every time I boot up the computer, just after the windows loading screen. It sais: "A problem has been detected and windows has been shut down to prevent damage to your computer. If this is the first time you've seen this Stop error screen, restart your computer. If this screen appears again, follow these steps: Check to be sure you have adequate disk space. If a driver is identified in the Stop message, disable the driver or check with the manufacturer for driver updates. Try chaging video adapters. Check with your hardware vendor for any BIOS updates. Disable BIOS memory options such as caching or shadowing. If you need to use Safe Mode to remove or disable components, restart your computer, press F8 to select Advanced Startup Options, and then select Safe Mode. Technical Information: *** STOP: 0x0000007e (0xC0000005, 0x00000000, 0xBAD03348, 0xBAD03044)" After this I've tried (to no avail): chkdsk /r new repair install (twice) safe mode reverting to last known configuration fiddling with various settings in the BIOS removing all USB devices I know my hardware is fine as my computer was running with no problems before my repair install. I'm figuring it must be something to do with a faulty driver or something else I haven't even thought of. Formatting and reinstalling isn't really an option because I'd rather drown than loose all my data and then go through the motions of reinstalling every single driver and program I have. I'm running (was running) a: Intel Core2 E8200 nVidia nForce 750i SLI FTW 8800gts (x2) XP Professional SP3 Any help would be greatly, vastly appreciated!
