Hi there. A friend of mine told me that he had some problems with some games crashing. I checked up his pc and noticed some small glitchs on some games, almost invisible. I tried to update the video drivers but it remained the same. I then tried the latest beta ATItool (b2) to check for artifacts. Well, it gives some errors from now and then, the strange part is that the error is allways the same. What could this mean, and could this lead to crashes/freeze but never a BSOD? I attached a screen with that error. The temps were never above 70ºC, as he has a VF700cu cooler. The rig is: Vista 32bits Conroe E6600 2G DDR2 800 Saphire ATI X1900XT 512Mb Asus P5B-E Deluxe Any of the components never had OC Tks for any reply or help.
