Radeon 9250 AGP setting problems

Ok, so i have an AGP graphics card (radeon 9250). Whats bugging me is that everytime i play this game called Battlefield. it randomly crashes to my desktop (If i recall correctly, it has been like this every since i got it. I'm beginning to think that its my graphics card problem.

Using EVEREST HOME, i found that the AGP BUS Setting was OFF was some reason (I believe it was on before). In the BIOS, AGP is enabled (something above it, i forgot, was set to AUTO but i could not change it)

Everytime i go in the catalyst to enable AGP speed (which is currently at 0), it always ask to restart so SMART..w/e can test. Everytime i restart, it switches back to original settings

I hope someone can help w/ this problem

Thanks
