4. Instruccions de funcionament
4.1 Encès inicial
After all components are securely installed and connected, ensure your power supply is switched on. Press the power button on your computer case. The system should initiate the boot process.
4.2 Accés a la BIOS/UEFI
During startup, repeatedly press the designated key (commonly DEL, F2, o F10) to enter the BIOS/UEFI setup utility. Here you can configure boot order, system time, and other hardware settings.
4.3 Instal·lació del controlador
After installing your operating system, install the necessary drivers for the chipset, LAN, and audio components. These drivers are typically provided on a support CD or available for download from the manufacturer's weblloc.
5. Manteniment
5.1 Neteja general
Netegeu regularment la pols de la caixa de l'ordinador i dels components de la placa base amb aire comprimit. Assegureu-vos que el sistema estigui apagat i desendollat abans de netejar-lo.
5.2 CMOS Reset
If you encounter system instability or boot issues, resetting the CMOS (Complementary Metal-Oxide-Semiconductor) can resolve problems by restoring BIOS settings to default. This can typically be done by removing the small coin-cell battery on the motherboard for a few minutes, or by using a dedicated CMOS clear jumper (refer to the motherboard layout for location).
5.3 Contact Cleaning
In cases of poor contact leading to issues, carefully remove and re-seat components such as RAM, CPU, and graphics card. The metal contacts on these components can be gently wiped with a clean, soft eraser to improve conductivity. Ensure the system is powered off and unplugged before handling internal components.
6. Solució De Problemes
If you experience issues such as no display, no power, no screen, or problems with the network or sound card after installation, consider the following steps:
- Comproveu les connexions d'alimentació: Ensure all power cables (24-pin ATX, CPU power) are securely connected to the motherboard and the power supply.
- Check Component Seating: Confirm that the CPU, RAM modules, and any installed graphics cards are correctly and fully seated in their respective slots.
- Restabliment del CMOS: Perform a CMOS reset as described in Section 5.2.
- Contactes nets: If issues persist, carefully remove and clean the metal contacts of the CPU, memory, and graphics card using a soft eraser, then re-install them.
- Prova amb components mínims: Try booting the system with only essential components installed (CPU, one RAM stick, power supply, and a display connected to the integrated or dedicated graphics).
- Check Peripherals: Ensure all external peripherals are correctly connected and functional.
