I'm getting BSODs whenever I play games, and when I try to power off

Above is the link to my zipped minidump files.

The computer is totally functional with no errors, up until I enter any videogame or try to power off. I'm hit within 5-10 minutes of starting a game.

The BSODs are usually:
IRQL_NOT_LESS_OR_EQUAL

DRIVER_VERIFIER_DETECTED_VIOLATION

SYSTEM_THREAD_EXCEPTION_NOT_HANDLED

My initial thought was that my CPU was overheating, so I replaced the thermal paste but this solved nothing. I ran a memcheck (4 passes) with no errors.
I checked my HDD and found that I had one uncorrectable sector, but I don't know what that means nor do I believe it is relevant to my bluescreens (even though I know I need to fix it).
I also reinstalled windows at some point.

OS: Windows 10
MoBo: Asus P8Z77-V LX
CPU: Intel i5-3550
GPU: Sapphire Radeon HD 6870
