After switching to Linux, I've had the annoying problem that my computer randomly freezes. At first I thought it only happened in Debian derived distributions, as it ran fine with 13.2, Mageia, and Mandriva. But now I'm getting freezes in Leap 42.1 as well.

The freezes are total, I can not move the cursor, or switch to a virtual console, or do REISUB. If there's any sound, it gets stuck in a BRZZZZ loop. It mostly happens in games, but can happen when watching videos or just during internet browsing as well.

I feel like I have checked everything, RAM is fine, temperatures are fine, I do not see any explanations in the logs (not that I know what to look for either). Only suspect is my SSD, which has two bad sectors, but can that really be it? Gnome Disks says it's OK.

Athlon II X3 460
Radeon HD 7770 (at first I ran with fglrx, after removing it again it seems to freeze less)

Any ideas are deeply appreciated.
