Hello TheCharly.
Usually the pink screen problem may occur on burned graphics cards. However I will do my best to rectify your situation.
1-)Please tell us, is this an on-board or a graphics card?
2-)Download the program named Furmark and share the test results with us. It will help you ensure that your card is rock solid/sick.
3-)Do you have the same problem with pink colors in other games? Also you can test it by opening a volcano picture or watching movie.
4-)After these steps, we can get something clear.
I'm waiting for your answer. Good luck. :y:
Thanx for your attention.
