5. Vianmääritys
5.1 Ei virtaa / Ei käynnistystä
- Verify all power cables (24-pin ATX, 8+4 pin CPU) are securely connected to the motherboard and power supply.
- Varmista, että virtakytkin on ON-asennossa.
- Tarkista etupaneelin virtapainikkeen liitännät.
- Testaa virtalähde toisella järjestelmällä tai virtalähdetesterillä.
5.2 Ei näyttöä
- Ensure the monitor is connected to the correct graphics output (either integrated graphics on APU or dedicated graphics card).
- Aseta näytönohjain ja muistimoduulit uudelleen paikoilleen.
- If using a dedicated graphics card, ensure it is properly powered.
- Kokeile käynnistää kone vain yhdellä RAM-muistitikulla.
5.3 Komponenttia ei havaittu
- Varastointi: Check SATA data and power cables. For M.2 drives, ensure they are properly seated and secured. Verify settings in BIOS/UEFI.
- RAM: Reseat modules. Ensure they are in the correct slots for dual-channel operation (refer to motherboard manual for specific slot configuration).
- Oheislaitteet: Try different USB ports. Ensure drivers are installed.
5.4 Järjestelmän epävakaus / kaatumiset
- Varmista, että kaikki ajurit ovat ajan tasalla.
- Tarkista suorittimen ja näytönohjaimen lämpötilat ylikuumenemisen estämiseksi.
- Suorita muistidiagnostiikkatyökalut tarkistaaksesi viallisen RAM-muistin.
- Jos ylikellotat, palauta oletusasetukset tarkistaaksesi vakauden.
