Question Desktop freezing or rebooting - Kernel Power 41 (63), Bugcheckcode 278/281

[ranqrusu]

Hi everyone. Ever since about a week ago, my prebuilt Alienware Desktop that i use for gaming has started being a nuisance.
Everything worked fine beforehand, but in the last couple days my desktop either suddenly has a freeze of death and i have to hard reboot it, or the desktop freezes and after a couple seconds auto-restarts. I've been trying to troubleshoot myself and found a couple useful threads, but was unable to resolve the issue at hand. Those threads seem to suggest graphics card driver issues or power supply issues.

The crashes seem to happen unrelated to whether or not a game is running or the runtime, sometimes i have a streak of no crashes at all for hours, and worst-case my PC crashes 6 times over the course of 30 minutes and 8 times a day. I share the room with a roommate who also uses his notebook for gaming.

What i've tried:
Rollback Graphics card driver in devmanager, completely uninstall and reinstall graphics card driver manually
Install all Windows updates
Run System File Checker
Uncheck "Perform automatic reboot"
Monitor GPU heat (idling around 40, going to 80 when playing games)

My computer:
pre-built Alienware Area-51 R2 x64

Intel (R) Core(TM) i7-6900k CPU @ 3.20 GHz [01]: Intel64 Family 6 Model 79 Stepping 1 GenuineIntel ~3193 MHz
