I just got a graphics card (Radeon 9250), and so far I know its working, but for one of the games, Gunbound, about 4/5 of the times I open it, I get a blue error screen and forces me to reboot.
This is generaly what is says:

Found a problem, must restart now to protect from damage
Check on any new software or hardway and make sure its installed correctly.
If problem continues disable, or remove any new hard/soft ware
or update the hard/soft ware.
Disable BIOS memory such as caching or shadowing.

Technical info:
*** STOP:0x000000BE (0x004400ZE, 0x053BD005, 0xB5BA7B7C, 0x0000000A)

Begining dump of physical memory
Dump complete.

Then when I boot up agian it says I have recovered from a serious error. I looked at the error report contents and it shows 2 files:

CDOCUME~1houseLOCALS~1TempWERf1a9.dir00Mini082906-01.dmp
CDOCUME~1houseLOCALS~1TempWERf1a9.dir00sysdata.xml

Im not sure if its my Graphics card or my comp, and all the other 3-d games are working just fine.

If it`s only happening with this one game, then I suspect it`s an issue with the game itself.

Try uninstalling and reinstalling the game. If that doesn`t help, go to the game manufacturers website and check for any patches that may be available.
