- Intermittent Power/System Instability:
- Ensure the PSU fan is spinning and not obstructed. Overheating can cause instability.
- Check for any loose internal connections.
- If possible, test the power supply with a PSU tester or by swapping with a known good unit to rule out other component failures.
- അസാധാരണമായ ശബ്ദങ്ങൾ:
- A grinding or buzzing noise from the PSU often indicates a failing fan. Clean the fan or consider replacement if the noise persists.
