PC & hardware
Start with what you can observe. Check connections before working inside your PC.

The PC shows signs of power, but the monitor has no usable picture. Check the monitor, selected input, cable and video output before moving on to internal components.

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.

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.
View solutionPC turns on then immediately shuts off
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.
