I bought a used r9 270x a week or so ago. It couldnt boot into Windows but i managed to install the drivers through safe mode. Installed a few games alongside with heaven benchmark, which went on extreme preset without any hiccups or arfitacts, and the score was more than i expected. CSGO and LOL were also stable around 300 and 140 fps respectively. When i went to the Witcher 3 and clicked on new game before lowering my settings to medium, the computrer instantly froze showing nothing but a giant artifact on the screen. Now i can't boot to Windows with a driver installed. Update mobo and gpu bioses to the latest and also tried Legacy drivers. Got any ideas to why it is like this? Could it be the issue with my HDD rather than my GPU?
