hey there. ok first off i gotta say sorry to you because i'm in the same boat i get the same errors and i think you'll find if you do a stock install of windows xp(format and reinstall) go straight onto sp1 you'll get the win32k.sys error as welll, the bsod fields you are getting are obviously 0x0000008E, 0x0000000a, and 0x00000050 ... And your comp after you restart it problem comes up with the send error report and microsoft gives you the device driver issue but they havent a clue what it is...

ok basicly the device driver for your 6800GT isn't working, with the kernal (which is the heart of the OS ie the IRQL list) This is a known error no user action can be taken until nvidia release the latest drivers although i am running beta drivers 67.02 now these take the IRQL error pfn list corrupt and the other one away but your just left with the win32k.sys error not so bad this one if you uninstall all related network drivers but don't bother as its a rare Blue screen anyway that ones the 0x00000050. The only action i can possibly gather from all the forums i've been to update your bios for your motherboard (INSTALL THIS ONLY IN ENABLE VGA MODE DO NOT ATTEMPT TO INSTALL IT IN NORMAL MODE I PLEA WITH YOU IF YOU HIT THE BSOD WHILE MID INSTALL YOU WILL PAPERWEIGHT YOUR COMPUTER but it can be reset )

To enable vga mode

After download the bios update, restart your computer
Hit F8 every second , ie 1..2..3..4..5..6
Enable vga mode (vga mode only uses windowsxp display drivers a little like safemode but with more drivers allowed)
Install your bios stuff following the onscreen instructions

now go to your new bios somethings may have changed, disable all shadowing and cacheing for graphics card as it does it its self as well as with xp commands to it. if you get the win32k.sys error copy the number down and search at microsoft.com as best as you can for what your symtoms are it will probbly say its an error with your display drivers and net******* if its in your services (control pannel-> admin tools-> services) right click it, hit properties then in one of the tabs change it to "take no action" if and if you get erros back with that do the f8 thing again and go to safemode back into services and put it on what it was before or a different setting. some links below to the beta drivers
