About a month ago I bought this computer, it works normally for a time, but then it freezes (mouse and keyboard with no response, sound or music enters in loop of 1s). All the time that this happens is during games (X-COM 2, Civilization V and others). I found some possible solutions on Internet and tried all of them:
-> update BIOS (was F5)
-> disable C6 in BIOS
-> disable IOMMU in BIOS
-> lower NorthBridge frequency in BIOS
-> check CPU temperature (never over 75ºC)
-> try another PSU (used Corsair CX-500W)
-> test memory (used Linux Memory test, all passed)
Can someone help? Is there any specific configuration that I should try?
If the only time your computer is freezing is during game play, then you're problem may not be the hardware.
Look into the software, Ubuntu has been know to be a little buggy when it comes to the latest games.
Update Ubuntu, the drivers, Steam, and Games.
I found an update for driver, I will install later and see what happens. I tried Steam OS too and the behavior is the same (guess is exact same driver).
Its first time that use Radeon GPU. I had another 3 PCs with Linux, AMD CPUs, but all with NVidia GPUs and never had problem like this.
