MSI 8850 Stop Errors IN XP



I recently updated my bios to the nvidia refrence bios by suggestion of the old msi forum as a fix to get the tv-out to work in XP. Now that i have done that i recieve stop errors constatnly in windows XP. I was wondering if anyone had a copy of MSI 8850 bios, which will hopefully rectify this situation. I have tried updating my MB bios, as well as all my drivers, but that has been no help. Thanks in advance.
