Lately I've been running into strange graphical glitches when playing different games. The most common things are white lines in textures, textures/objects stretching infinitely and especially in Dark Messiah, crashing/locking/rebooting/BSOD.
I assume this has something to do with the graphics card/driver but I'm not sure which is at fault and why.
Converting on of the minidumps from a crash yielded:
IMAGE_NAME: nv4_disp.dll
DEBUG_FLR_IMAGE_TIMESTAMP: 44dd4897
MODULE_NAME: nv4_disp
FAULTING_MODULE: bf9d4000 nv4_disp
DEFAULT_BUCKET_ID: GRAPHICS_DRIVER_FAULT
CUSTOMER_CRASH_COUNT: 2
BUGCHECK_STR: 0xEA
PROCESS_NAME: mm.exe
and a whole lot more of text...
What I've done so far:
Updated DX9c
Removed old drivers with Driver Cleaner and reinstalled latest drivers.
Checked temperature on the graphicscard, around 45 C (109 F, I think)
So if anyone wouldn't mind reading this entire post, which seems to get a bit lengthy and make a couple of suggestions on what might be wrong and maybe how to fix it, I'd be very happy. 
Oh, maybe some specs on the system might be of interest too... let me see...
AMD X2 3800+
EVGA GF7900 GT CO
Kingston KVR 1 gb
Audigy 2 platinum
ASUS A8N-E
Antec 450 W PSU
