PC randomly restarts or shuts down during heavy gaming with NO blue screen
Computer instantly goes black and powers off or restarts under heavy graphics load without creating a BSOD minidump.
Internal desktop parts run on harmless 12V DC voltage and cannot shock you. Simply unplug the wall power cable first, then touch the unpainted metal case frame to ground static electricity.

Interactive Fix Checklist
0 of 4 steps completedSafety power-off and discharge
Shut down the PC, turn off the power supply rocker switch (O), and unplug the AC power cord from the wall outlet. Press the front power button once while unplugged to discharge residual capacitor energy before touching any internal components.
Use separate PCIe power cables instead of daisy-chained pigtail cables
Check power connectors. High-power graphics cards (RTX 3080/4080, RX 6800/7900) draw up to 350W+. Never use a single split 'pigtail' cable for two 8-pin ports. Run two or three separate individual cables directly from .
Test GPU power target or undervolt to tame transient spikes
In MSI Afterburner, reduce 'Power Limit' slider to 85% or apply a gentle undervolt. If the PC stops crashing during benchmarks, your is failing to handle microsecond power spikes.
Verify PSU wattage and 12V rail health
Check your rated wattage against total system draw. Modern GPUs have transient spikes up to 2x TDP lasting 10 milliseconds. Older PSUs shut down immediately to protect components.
