You don't know who made your computer and what model it is?
In will be on the box
OR Right click MyComputer and left click properties
duno like cs source and sumthin like that
I'm not gonna guess here???
Is it CS source or isn't it??
What other games do you have problems with?
With the above info you only supplied
I suggest that you try the later drives from Nvidia
Download and save them too desktop
DON'T Install them yet
http://www.nvidia.com/object/winxp_2k_84.21.htmlGo into add/remove programs and remove
NVIDIA Windows Display Drivers" OR "NVIDIA Drivers"
Whatever is listed
REboot the computer when prompted
If on startup you get new hardware found, just cancel it out
Double click to install the new driver you saved too desktop
Reboot again when prompted, see if that helps
