If your PC only crashes during gaming (not during normal use), the issue is almost always GPU, PSU, or thermal related. Here's how to pinpoint it.
Thermal CrashesDownload HWMonitor or MSI Afterburner. If GPU exceeds 95°C or CPU exceeds 100°C, thermal throttling causes crashes. Fix: clean fans, reapply thermal paste, ensure case has adequate airflow (intake + exhaust fans).
GPU Issues1. Driver crash: Screen goes black, then recovers with "Display driver has recovered" — update or clean-install GPU drivers using DDU 2. Artifacts: Colored pixels, lines, or screen tearing — GPU memory failing 3. Hard crash: PC reboots instantly — check GPU power cables and PSU wattage
PSU (Power Supply) IssuesUnderpowered PSU is a silent killer. A system that draws 450W on an 500W PSU has no headroom. Under gaming load, the PSU shuts down protectively. Use online PSU calculators and aim for 20–30% headroom.
RAM & SoftwareBad RAM causes random crashes. Run MemTest86 overnight. Also check: Windows is up to date, game files are verified (Steam → Properties → Verify), and no background recording/streaming software is conflicting.
