Yep, I've got a problem with them. I'm using Windows XP SP2, Catalyst 8.8. Any time I run GPU-Z (0.2.7), with KIS (Kaspersky Internet Security ver 22.214.171.1245) protection enabled, it doesn't start. Just shows off the logo TechpowerUp GPU-Z and stay there until I terminate it by using Windows Task Manager. After that, every program that I attemp to run will not start, screen shows nothing, but visible Windows task manager . Then, I tried to exit KIS, but it wouldn't (can't kill it because of KIS's self-defense system >.< ) => tried to restart the computer but it wouldn't be restarted because it couldn't shutdown, just stop at "Goodbye screen" => pressed the power button in 5s I tried to add GPU-Z to KIS exclusions threats, but it still doesn't work Have to exit KIS before using GPU-Z. This could be a bug of KIS, but I think I should tell you, W1zz.. Thanks for reading.
