I have bought refurbished DELL PC. It is quite good computer with Intel Pentium processor at 2.4 GHz, 512MB RAM and ATI RADEON 9600 video card. Programs work fine, but when I try to run some games I have a problem. In many games graphics is corrupted and I can not play them. Do you know what the problem here is?
It seems to me that you are using outdated video card driver, if this problem occurs with newer games. Go to ATI official web site and download appropriate driver for your video card. Do not forget to completely uninstall old driver before new driver installation. You can use DriverCleaner utility to be sure that every driver component is uninstalled.
