So 2 days ago while playing War Thunder on high settings my monitor suddenly turned gray, actually gray vertical stripes.
I'm sure the problem here is my graphics card, i've had it for 3 years now Radeon HD 7800, worked well till 2 days ago.
Yesterday I installed the newest drivers and it stopped showing anything at all and the screen is just black but the graphics card's fans are still working.
It only works in safe mode or while the drivers are uninstalled but still i can't play any games, because it says i have only 30MB of memory on my card.
Please help! :(

Unfortunately none of that worked :( Do you have any other ideas?
