so i have Gigabyte Geforce GTX 760 graphic card , i was opening overwatch like usual then i saw some small green lines scattered or over the screen , felt like something was really wrong with GPU then i got crashed and error said " rendering device lost " then when i rebooted my pc after windows load i get a black screen with white squares and lines then screen goes off into sleep and after i wake it up windows starts this also happens with every driver i install at the moment it activates the driver and when i go to device manager the GPU driver has a yellow exclamation mark , 0 VRAM in dxdiag and i have tried reinstalling and installing driver 234234 times different driver versions each time , SO does that mean my GPU is dead ?
these are the green lines i mentioned
