I just got my new system with a 7800 GT CO installed. Yesterday I was playing Half-Life 2 when I got a BSOD saying the file nv4_disp.dll was the problem and it was beginning a memory dump. So, I tried playing HL2 again, this time keeping an eye on the GPU temp. It was getting to about 70C. Since I am havent been into graphics cards for a while, is this too high or what may have caused the problem? Also, I've noticed people complain that their fan gets very loud - I can barely hear mine with the case cover off and I don't hear a change in fan speed when starting a graphics intensive app like HL2. Anyone's thoughts would be greatly appreciated. Thanks!
