Hey i recently came into a bit of trouble with my graphics card, its an ASUS 770 2g ive had it for 2 years now and its worked perfectly fine, but everytime i go on a website or a game my display driver crashes and my screen flickers black and i have to use control panel to shut down the game or page im on, if i don't close it down quick enough the computer blue screens and restarts, ive tried updating my graphics drivers and uninstalling them i have come to no conclusion on how to fix the problem, the only thing that works is opening my GPU tweak and turning down the GPU clock and memory clock of my graphics card, this allows me to browse and play some games on varying levels but the framerate suffers and the card is practically useless, any idea's ?
