I recently bought an xfx r9 290 card after upgrading from an nvidia card. For the first couple weeks after installing it everything was fine. Now I get frequent blackscreen crashes where my only option is to reboot the system.These crashes occur frequently in specific games like the new wolfenstein and sleeping dogs, but they also occur when I am just browsing the web. I also get an occasional bluescreen but it isn't as frequent. I downloaded furmark, and if I do a burn in test I consistently get a blackscreen crash doing the burn in test at around 90 degrees celsius. The first week I had my card it would reach a maximum of 94 degrees celsius during full load and experience no issues. What should I do? here are my specs
