Why does Black Desert (Remastered) restart my Intel Core i9 13900K system?

I panicked when the screen went black during a final battle in the desert ruins. I tried replacing the 24-pin power cable, but the loose connection caused more issues. I then opened GamePP Resource Scheduler, setting the game priority to Real-time. Cinebench R23 showed voltage fluctuation dropped from 0.05V to 0.01V. AIDA64 recorded fan speed stable at 800-1000 RPM. After 4 hours, zero restarts occurred. This precise scheduling fix the underlying instability.
