Why your PC overheats and shuts down
On this page
- Dust in the grilles and the fan: air no longer circulates.
- Dried-out thermal paste: the processor dissipates its heat poorly.
- Blocked or worn fan, often noisy before it fails.
- Faulty power supply: the PC shuts off without warning, even without getting hot.
- Motherboard or component fault in rarer cases.
The right steps
- Put a laptop on a hard, flat surface, not on a bed or on your lap.
- Avoid continuous use if the device is scorching hot.
- Do not blow with your mouth and do not use a vacuum cleaner on the components: static electricity can damage them.
If the device shuts off more and more often, have it examined: repeated overheating wears out the components.
What we do
- Free diagnosis: temperatures, fan, power supply.
- Full cleaning and replacement of the thermal paste: see computer cleaning in Brussels.
- Replacement of the fan or the power supply if needed.
- If the motherboard is affected, see the microsoldering.

Before you come to the workshop: what to know
For a quick diagnosis, bring the PC with its power supply or charger. Note in which situations it gets hot (gaming, video, simple browsing), since when the fan has been noisy and whether it shuts off suddenly. These details help us target the fault from the start.
Avoid using the device continuously while you wait: repeated overheating damages components and can make the repair more expensive.
Can’t come right away? Write to us on WhatsApp with a photo and a short description: we tell you whether it is worth coming in. The diagnosis remains free and carries no obligation, and the price is confirmed before any repair. Our workshop is in Schaerbeek and welcomes customers from Brussels and the neighbouring municipalities.
When your PC overheats, the first reflex is to check ventilation. If your PC overheats even at rest, the thermal paste or the fan is at fault. Your PC mostly overheats during heavy use, but the power supply matters too.
