Heard in a couple places that the K7VT4APro board has some voltage issues with it's AGP. From what I've been seeing when playing 3D graphic games is seeming to be true. Quite often getting screen flashing leading to screen/system freeze, adnormtormination of program, stop of display driver. The only thing I changed in my system recently has been the motherboard, with the last one there was no issues. But other then 3D gaming..or at lesat in one game there is no problems.
