I have an ATI Radeon 9600XT 256mb. graphics card which I have recently purchased. Previously I had an ATI Radeon 9200 128mb card. I am running an Athlon XP3000+ processor with 512mb. of DDR memory. My problem is that since I have upgraded to this new graphics card I have had lockups in some of my games. Most notably Race Drive 1 and 2 and MotoGp 1 and 2. My lockups are occurring randomly, apart from that there is no problem at all. I have now gone back to my old 9200 card and everything works fine. I am also using the latest drivers, which I was also doing with the 9600XT. Do you have any idea of what the cause of my locking up would be?
