PC shuts down while gaming
The PC stops during a game and does not restart on its own. Distinguish loss of power from a display that merely goes black. Power and cooling need investigation, but a shutdown alone does not prove a bad PSU.

See all the clues. Choose the one that matches what you observe.
External power is in question
Check only undamaged external cable and outlet; shutdown alone does not identify the PSU.
There are prior thermal signals
Use already available readings and model limits; do not run a workload to obtain them.
Started after hardware or performance changes
Distinguish configuration change, compatibility and power demand before blaming a component.
Diagnostic signals
- ObservationThe PC stays off
- If the game and audio continue and only video disappears, investigate the display path. Returning to the boot logo on its own is a restart.
- ObservationFailure follows a period of use
- A relationship with load or ventilation is a reason to check cooling, not a substitute for measurement or proof of a failed part.
- ObservationOne game versus several workloads
- Use existing observations: one game first points toward its workload/software pattern; several demanding programs broaden suspicion to the system, without proving the PSU.
Step-by-step solutions
Clear external airflow
Do not keep gaming to try to confirm overheating.
Stop the demanding workload and keep case air intakes and exhausts clear. Do not run the PC covered or enclosed.
With the PC off and unplugged, look for blocked vents from outside. Follow its manual for cleaning; do not insert objects or open the PSU.
Check external power
Rule out a damaged external cable or connection.
Turn the PC off and unplug it before checking the external power cord. Do not use a damaged cord or loose connector.
If there are no signs of damage, check with a known-working outlet or known-compatible external power cord. Ask a professional if the electrical installation is in doubt.
Advanced checks
Continue if the earlier steps did not help. Read each procedure’s precautions first.
Compare the correct metric without forcing load
If the PC remains stable at idle, use an already available official tool without adding load. Retain CPU, GPU, sensor name and whether the reading was at idle or in-game. A reading after restarting does not represent the temperature before shutdown.
Compare CPU readings with the exact processor specification and GPU readings with that card manufacturer’s specification. Core temperature, junction/hotspot and another model’s limit are not interchangeable. Reaching a limit can trigger throttling; it does not by itself prove it caused shutdown.
With already recorded abnormal readings, blocked ventilation or suspect cooling, prioritize thermal review. Without comparable data, keep the hypothesis open and request review instead of starting a stress test. If it shuts down at idle or coolant leaks, stop using it.
Review the prior change with recovery prepared
Record whether it began after changing GPU, RAM or CPU, or enabling XMP/EXPO, overclock or undervolt. Those profiles are not standard settings. If related, ask the manufacturer or technician to revert only the changed setting following the manual; do not load global BIOS defaults or try voltages.
If restoring the previous configuration leaves it stable during normal use, configuration/compatibility becomes more suspect; it does not necessarily identify faulty RAM or PSU. If it shuts down again, stop the workload and request assessment. Do not repeat games or stress tests to confirm.
Prepare a power review with useful data
From documentation, gather PSU model and age, CPU/GPU and recent upgrades. Shutdown across several workloads or after a new GPU justifies a technician reviewing capacity, connections and condition; printed wattage does not establish quality or condition.
In Event Viewer > Windows Logs > System, retain events near the already known time. Kernel-Power 41 confirms unclean shutdown, not a defective PSU. If WHEA-Logger appears, retain its details for support; an isolated corrected event does not automatically identify the part that caused shutdown.
Absence of WHEA does not exclude hardware: abrupt power loss may leave no useful record. If only one game fails, include its version and workload timing; if several fail, say so without running more. Avoid buying a PSU based only on that pattern.
Still not working?
If shutdowns recur, stop gaming and request review with the prior pattern, configuration, available readings and events. A next step must distinguish a specific hypothesis; repeating shutdown only exposes data and hardware.

PC restarts while gaming
The PC boots again on its own during a game. A Windows crash, instability or interrupted power can end in a restart; the symptom does not identify one component. If it stays off, use the gaming shutdown guide.

Pressing power produces a brief response, then the PC shuts off before it can boot. Start with external power and recent changes. If it stays on without video, use the no-display guide instead.
