Why does Dead Space Remake cause sudden black screen reboots?

Every time I loaded massive resources in the space station, the system would black screen and reboot without warning, leaving me incredibly anxious. I tried disabling CPU Turbo Boost in the BIOS; while reboots decreased, my minimum FPS tanked from 70 to 45 per RTSS, which was a depressing trade-off. I used the GamePP Power Plan Switcher to set the system to High Performance and adjusted the motherboard load-line voltage to L2 mode. A multimeter check confirmed the 12V rail stabilized at 11.9V-12.1V, and GamePP Resource Scheduler showed GPU voltage steady at 0.9-1.1V.
