My PC has been crashing since a while now. I ran a GPU test with FurMark and I saw temperatures soaring upto 82° before shutting down. Now I'm about check the psu with HWMonitor. Please tell me all the hardware I'll have to replace.
82C is not high enough to crash your system, there must be some other problem, like faulty psu, improper ram settings, any unstable overclock.
Have you changed any settings recently?
I'm not what you mean by gpu driver. Catalyst Control Center?
I'm getting this problem with only a few games. Dishonored works but Dead Island Riptide doesn't :/
Yes I mean catalyst control center. If you have problem with only a few games then there might be no problem with your card at all. Also AMD frequently releases application settings/profiles (or something similar) that is required to run a specific game.
You should consult websites like these for specific game errors
