Why do my pc gets green screen while playing video games?

[OliverHun]

So the thing is , that my pc worked fine , but for now when i play games its randomly gets a green screen and the sound loops in the background. Sounds like a blue death with a green screen. After i restart the computer everything is good , but if i try to play again i get the same issue.

gpu: ati radeon r93xx series

Try reinstalling/ updating your GPU drivers.

Tried it , even downgrading it . Nothing worked .

Do you monitor your temperatures? It can be caused due to overheating.

 

[OliverHun]

Yeah, my card showed me 87 last time, i think its fine

It would be good if you could get the exact specs of your GPU, not just "radeon r93xx series".

How is your airflow in the case?
And when was the last time you cleaned your PC from dust? (including GPU)

 

[OliverHun]

Its a r9380 , the airflow should be okay , cause it worked before and i didnt had crashes ( the pc is laying on ther ground , not standing ) . When i got the crashes i cleaned the pc , even took out the gpu and placed it back. I think that day worked again everything perfect but , after it went back to the same problem

Few things to try:
Try with another GPU and see if problem exsists.
Try your GPU in another system and see if problem appears there too.

One another thing to try is to take a screenshot when you see that green screen.
If you take a photo you get what you see but when you take a screenshot in Windows, it takes all the data from the buffer. If the data there is corrupt, then the problem is likely on the driver end. While if it's not corrupt there but does show up bad it's quite likely either GPU or monitor.
