Hello everyone . I have this problem with my graphics card , Ati radeon 4850 1gb 256 bit GDDR3 . I've recently changed it . at first everything was ok but then I realized that something is wrong . It was my power supply that wasn't able to handle it . I've changed it to Clacial Power 700 watt. It's a powerfull one . But I'm having this problem now Every game I launch starts for several minutes than my display just freezes and then I am thrown to desktop with a note that this program needs to close . I've tried to reinstall this drivers but it is useless . And I get this note that GRAPHICS DRIVER HAS STOPPED WORKING AND RECOVERED . My system is Core 2 Duo E7500 , RAM - 4GB DDR2 800Mhz . ASUS P5B (very old) , 2 HDDs MAXTOR 250 GB a d SEAGATE 250 GB and 3 coolers in the case are attached . Anyone can help ? I am already tired of trying it on my own . So a little help will be very helpful
