Witcher 3 monitor flashes then crashes game


Thread Starter
Jun 13, 2021
When playing Witcher 3, the Asus ROG PG258Q 240 hz monitor begins flashing certain colour blocks and then freezes while the dialogue keeps going for a few seconds then closes out the game and goes to the windows screen. We updated the Nvdia drivers, windows drivers, and validated the game integrity files. This is still happening. We have a custom built PC, with a 1080ti graphics card. Is this a software or hardware issue do you know?

Not a lot to go on really.

Can you provide the following details:
CPU make and model
motherboard make and model
PSU make, model and wattage
RAM make, model and amount.

Can you also download and run the TSG System info utility, link below in my signature.

It could be hardware and/or software, a little hard to say at this stage.
