Freezing Issue Manifested after upgraded video card

[shustermds]

Hi,

I upgraded my video card from Nvidia Geforce 7300 to XFX GEforce 9500 GT. I updated to the latest drivers and am running the latest 1.65 patch of King's Bounty. I aligned my screen resolution and the resolution of the game (to 1280x76.

KB now fatally freezes (requiring a hard restart) after between 1 and 4 minutes of play. I've restored all the previous video settings that I'd been successfully running (about 7 hours of gameplay) with under my old video card, but to no avail.

I use windows XP media edition with service pack 3 and 3 GB RAM. Does anyone have any advise or do I need to re-install my old card for this game?
