This sounds a lot like a corrupted save game file, rather than a video card driver issue. The usual suggestion is to start over with an older save game file.

This might be your only option to salvage those 20+ hours of game play. But I wouldn't be overly optimistic if it truly is a corrupted save game file, as they tend to crash at the same place no matter which machine they're played on.
