PC Troubleshooting

This page is to help you with basic troubleshooting of your computer, notebook, and other devices, but only applies to major system problems, for specific problems like HDD or SSD not showing up there's special pages.

The steps should be pretty comprehensive, but the solution and problem can vary from system to system and the entry points can be completely different.

The full entry points are "System can't boot", "System can boot" and "System not lighting up".

You should go through the lists top to bottom, all checks should be done in order, and you should test after a couple checks.
