7. Otkrivanje problema
Ako naiđete na probleme s matičnom pločom, pogledajte sljedeće uobičajene korake za rješavanje problema:
- Nema napajanja:
- Check if the PSU is switched on and all power cables (24-pin ATX, 4-pin CPU) are securely connected.
- Provjerite je li kabel dugmeta za napajanje na prednjoj ploči ispravno spojen na konektor matične ploče.
- Bez prikaza:
- Verify that the monitor is connected to the correct video output (motherboard's VGA/HDMI or dedicated graphics card).
- Reseat the RAM modules. Try booting with only one RAM stick.
- If using a dedicated graphics card, ensure it is properly seated and has power.
- Clear CMOS (refer to motherboard manual for jumper location or remove/reinsert the CR2032L battery).
- Nestabilnost/Padovi sistema:
- Check CPU and GPU temperatures. Ensure coolers are properly installed and fans are spinning.
- Pokrenite alate za dijagnostiku memorije da biste provjerili da li postoji neispravan RAM.
- Provjerite da li su svi upravljački programi ažurirani.
- Check PSU wattage; it might be insufficient for your components.
- Periferni uređaj nije otkriven:
- Pokušajte spojiti periferni uređaj na drugi priključak.
- Provjerite jesu li instalirani upravljački programi perifernih uređaja.
