unfortunately i am unsure of when the problem started to occur, seeing as it only arised in my newest copy of "world of warcraft". I'm almost 80% sure that this is a graphical error, but cannot seem to find the problem. my computer freezes, locks up, but the processor seems to continue to run, and i cannot do anything. ( this is only in games.) in world of warcraft, when i am loading a level, or sometimes rendering parts of the world, it occurs (specifically, and oddly, when i move into an instance and the loading bar at the bottom of the screen is loading, the program exits. Also, at random times, not specific, i may be flying on a mount or doing some arbitary travel, nothing graphically intensive, and the computer freezes as described above.) Another case where this is happened, is a downloded a doom program called doomsday kickstart, which allows me to choose either "opengl" or "direct3d". when i first started the program, and its default was set to "opengl", i would get the identical crash symptom as in world of warcraft, THE MOMENT i would step forward. (crashing has only occured during movement, i have never crashed when running word or anything either, the only times are with world of warcraft and doom, i mean who the hell crashes in doom?) BUT when i changed the settings to "direct3d" the problem dissappeared. THOUGH i am unsure whether the game crashes at random spots like world of warcraft, i havent played it for long enough. Specs. Amd Athlon XP 3000+ Radeon 9600 XT ( i have the latest catalyst.......) Sound Blaster Audigy Ls (i think, and i dont think the drivers are a problem here) hope i got enough here for someone to identify some sort of problem,. thank you
