Why does Elden Ring crash during high-load Boss battles?

I've had enough! Every time I reach a critical Boss, the system crashes, which is the worst luck imaginable. I first tried enabling Auto-Overclocking in the BIOS, but temperatures spiked to 92℃ and crashes continued, making me furious. I used the GamePP BIOS Load-Line Voltage Adjustment Wizard to increase LLC from Level 2 to Level 4 and added a 0.03V Vcore offset. Voltage stabilized to 1.05-1.12V per Cinebench, Vcore drop was fixed via GamePP, and CPU temps stayed at 78-85℃ per AIDA64.
