When I installed 64bit OS on my PC, I wanted to play Fortnite a lot. I installed it and then it opened. It ran pretty smooth until I got on a game. The screen started glitching out.
Some days pass, I wanted to play CS:GO (Free Edition), I installed it but when it said "Loading textures...", the screen started glitching out, again. I found out that the GPU is the problem but I want an answer. How do I fix it? Is my GPU "bad"? I've tried: Underclocking, Overclocking, Resetting, Switching OS (Win7 to Win8.1 Pro), Updating drivers, Downloading outdated drivers, etc.
CPU: Intel Pentium E5300 Dual-Core CPU @ 2.60 GHz
