Why does No Rest for the Wicked crash during high-load Boss battles?

I've had enough! Every time I reach a critical moment in a Boss fight, the system just crashes; my luck is abysmal. I tried enabling Auto-Overclocking in the BIOS, but temps hit 95℃ per AIDA64 and it still crashed, which left me absolutely furious. I used the GamePP BIOS Load-Line Voltage Adjustment Wizard to raise LLC to Level 5 and added a 0.07V Vcore offset. OCCT tests showed voltage stabilized at 1.20-1.24V, with AIDA64 reporting 80-84℃.
