CUSTOM GAMING PC HIGH-PERFORMANCE DESKTOP General Troubleshooting

Power Supply Unit (PSU) - 80+ Gold 850W

The PSU is likely failing to regulate voltage during the high-transient power draws characteristic of modern GPUs. When the internal voltage rails dip below the acceptable tolerance or trigger protection circuits (OCP/OPP), the motherboard initiates a hard reset to protect components. Replacing the unit with a higher-efficiency, higher-wattage model ensures stable DC output during peak load.

High-Performance Thermal Interface Material

Degraded thermal paste or pump failure in a liquid cooler can lead to rapid heat accumulation on the CPU heat spreader. If the sensor detects temperatures exceeding the safety limit (usually 100°C), the BIOS triggers a thermal shutdown or restart sequence to prevent silicon melting. Re-applying high-grade thermal compound restores the heat transfer coefficient between the chip and the heatsink.

DDR4/DDR5 Memory Module

Memory instability, often caused by failing DRAM cells or incompatible XMP/DOCP overclocking profiles, can cause system-level execution errors. While this often results in a BSOD, a total failure of a memory address during a gaming load can lead to a kernel-level hang and subsequent hardware restart. Replacing the modules ensures data integrity during high-speed caching operations.
