Hello guys. I have a problem with my GPU. It isn't thermal throttling or anything. So, when I play games (some games, not all games, and it never happens anytime else) I get these weird artifacts. Like, my screen is full of all colored squares (mostly red, blue and yellow), and they are being rendered on game objects, like rocks, roads etc. Also, I get these vertically stretched objects, as seen on pictures. GPU is AMD Radeon 6850 Cyclone.
