Hi everyone! It's months I'm struggling with the problem in title and I've not found a solution yet. When I play, whatever game it is, after a while, the pc freeze or the amd driver crashes. I've got a sapphire r9 290x tri-x 4gb oc edition and these are the following steps I tried: unistalled-reinstalled gpu driver, installed an older one, removed broken registry keys with cccleaner, bought new case fans for a better airflow, changed gpu thermal paste with a high quality one, undervolted gpu, formatted. I've also changed mobo, ram and cpu. I've tried some benchmarks and gpu temp never go over 80°C but the tests last only few minutes. Psu is 750w. The only thing I noticed is that if my case panel is open the freezes and crashes need a bit more time to happen.
Maybe still a temp problem? Or gpu is broken? Thanks for any help
