Blue Screen(PC)

A lot and lots of blue screen crashes. Seems to be happening randomly.
After the last blue screen crash, just last night, something worse happened. I cant resume the game any more as I used to… I can press the resume button and it makes clicking sound… but no loading up the game…

Hello @oddgeirb, welcome to the community!

Which specific GPU do you have in the 7900 series?

How much RAM do you have on your system?

Are you using updated drivers for your GPU and is your Windows up-to-date, optional updates included?
