So when I run AVA in full screen mode it flickers like hell. I can't CTRL+ALT+DEL or anything to stop it. I have to manually press the power button on my computer to restart it. I have a ATI Radeon HD 4200 graphics card. I tired everything to fix it, I just can't come up with a solution! Underclocking, Overclocking, updating drivers, roll-back drivers, called AMD support, I even slapped my dick on the monitor hoping it will work( well I didn't but I'll try it if I get no solution!) I'm going nuts. Hours and hours trying to fix this problem. Now I come to you guys for help. I'm sick of playing in window mode.
