4. Setup and Installation
Before beginning installation, ensure your system is powered off and unplugged. Wear an anti-static wrist strap to prevent electrostatic discharge (ESD) damage to components.
4.1. CPU Installation
- Locate the AM4 socket on the motherboard.
- Lift the retention arm on the CPU socket.
- Carefully align the triangular marker on your AMD Ryzen CPU with the corresponding marker on the socket. Gently place the CPU into the socket without forcing it.
- Lower the retention arm to secure the CPU.
- Install your CPU cooler according to its manufacturer's instructions.
4.2. RAM (DDR4) Installation
- Open the clips on both ends of the DDR4 DIMM slots.
- Align the notch on your DDR4 memory module with the key in the DIMM slot.
- Press down firmly on both ends of the memory module until the clips snap into place. Ensure both clips are fully engaged.
4.3. Storage Device Installation
- M.2 SSD: Locate the M.2 slots. Insert the M.2 SSD at an angle into the slot and then gently push it down. Secure it with the provided screw.
- SATA Drives: Connect SATA data cables from your storage drives (HDDs/SSDs) to the SATA ports on the motherboard. Connect SATA power cables from your power supply to the drives.
4.4. Expansion Card Installation (e.g., Graphics Card)
- Locate the PCIe x16 slot for your graphics card.
- Remove the corresponding expansion slot cover from your PC case.
- Align the graphics card with the PCIe slot and press down firmly until it is seated correctly and the retention clip locks.
- Secure the graphics card to the case with a screw.
- Connect any necessary PCIe power cables from your power supply to the graphics card.
4.5. Power Connections
- Connect the 24-pin ATX main power connector from your power supply to the motherboard.
- Connect the 8-pin (or 4+4-pin) ATX 12V CPU power connector to the motherboard.
4.6. Front Panel Connections
Connect the front panel cables (power button, reset button, USB ports, audio jacks, LED indicators) from your PC case to the corresponding headers on the motherboard. Refer to the motherboard's detailed manual for exact pin layouts.
5. Operating Instructions
5.1. Initial Boot and BIOS/UEFI Setup
- After assembling your PC, connect a monitor, keyboard, and mouse.
- Power on your system. During startup, repeatedly press the Del or F2 key to enter the BIOS/UEFI setup utility.
- In the BIOS/UEFI, you can configure boot order, system time, fan speeds, and other advanced settings. Save changes before exiting.
5.2. Driver Installation
After installing your operating system, install the necessary drivers for your motherboard components (chipset, audio, LAN, graphics, etc.). These can typically be found on the ASRock official website for your specific motherboard model.
5.3. BIOS/UEFI Updates
ASRock regularly releases BIOS/UEFI updates to improve compatibility, stability, and performance. Refer to the ASRock website for the latest BIOS version and detailed instructions on how to update it. Some users may need to update the BIOS for compatibility with newer AMD Ryzen processors.
6. Maintenance
- Dust Removal: Regularly clean dust from your PC components, especially fans and heatsinks, using compressed air. Dust accumulation can lead to overheating.
- Cable Management: Ensure cables are neatly managed to improve airflow and prevent obstruction.
- Software Updates: Keep your operating system, drivers, and BIOS/UEFI updated to ensure optimal performance and security.
- Component Checks: Periodically check all connections (power, data, expansion cards) to ensure they are secure.
7. Troubleshooting
7.1. No Display / System Fails to Post
- Check Power: Ensure all power cables (24-pin ATX, 8-pin CPU, PCIe for graphics card) are securely connected.
- Reseat Components: Try reseating the CPU, RAM modules, and graphics card.
- Clear CMOS: Refer to your motherboard manual for instructions on how to clear the CMOS (Complementary Metal-Oxide-Semiconductor) settings, which can resolve boot issues.
- Test with Minimal Components: Remove all non-essential components (extra storage drives, expansion cards) and try booting with only the CPU, one RAM stick, and the graphics card (if no integrated graphics).
- BIOS Update: If using a newer Ryzen CPU, ensure your BIOS is updated to a version that supports it.
7.2. System Instability / Crashes
- Check Temperatures: Monitor CPU and GPU temperatures. Overheating can cause instability. Ensure proper cooling.
- Update Drivers: Outdated or corrupted drivers can lead to system instability.
- Test RAM: Run memory diagnostic tools to check for faulty RAM modules.
- Power Supply: Ensure your power supply unit (PSU) provides sufficient and stable power to all components.
7.3. Peripheral Not Detected
- Check Connections: Ensure the peripheral is correctly plugged into the appropriate port.
- Install Drivers: Install the necessary drivers for the peripheral.
- Test on Another Port/System: Try connecting the peripheral to a different port or another computer to rule out a faulty peripheral.
