XFX R7770 1GB no display

Hey

In the following game my problem happends :
World of tanks, World of warplanes and APB Reloaded.

On world of tanks and world of warplanes it happends random and can take up to 1 time a day to 1 time a month.

i downloaded APB Reloaded to play with friends. but just 5 secs in game and my screen already goes black

Screen says no signal. PC needs a reboot and than display is back.

I tryed Latest drivers
Downgrading gpu drives
Opposite of overclocking ( dont know the name) Downclocking ? my card

is this because i use windows 8.1 when my motherboard doesnt have drivers for it ? since my GPU Does have them

Somehow AMD Autodetect isnt detecting my GPU

Forgotten to mention this only happends with some games, played 60-70 hours on BF4 and never did happen
Same goes for euro truck simulator played plenty of hours but never had it

run it and then find the mb vendor...if it amd or intel look at the chipset used.

if the chipset driver is not missing make sure the video cable on the gpu and not the mb.
use msi afterburner to check the gpu fan try maxing the fan out see if the fan spins up.
if msi cant see the gpu with the newest chipset drivers installed. may have a bad gpu card.

My card is working in my system for sure. runned a stress test for 5 hours long on furmark and didnt get pass the 70degree mark als i can change my fan speed

if it not a heat issue...check the gpu ram for a bad spot there few free gpu ram testers out there. the last would be a weak power supply. gpu spikes the power supply at game start and the power supply drops below atx spec causing pc to reset.

but BF4 is a way more asking game than ABP reloaded. why i runned 60 hours bf4 without any problem. and APB has within 5 secs on the beginning a no signal.

iFor APB its the same point losing signal
For World of tanks and warplanes it is completely random once a week or once a month its so random
