2. Specifications

3. Package Contents

The package typically includes:

• HP Pro 490 G1 G2 Desktop Motherboard MS-7933 V1.0 (as pictured)

Note: Additional accessories such as SATA cables, I/O shield, or manuals may not be included unless explicitly stated by the seller.

4. Setup and Installation

4.1 Safety Precautions

• Always disconnect the power supply from your computer before installing or removing any components.
• Wear an anti-static wrist strap or frequently touch a grounded metal object to discharge static electricity, which can damage electronic components.
• Handle the motherboard by its edges, avoiding contact with components and connectors.
• Ensure you are working in a well-lit and clean environment.

4.2 Motherboard Installation

1. Prepare the Case: Ensure your computer case is clean and has the necessary standoffs installed for the ATX form factor of this motherboard.
2. Install I/O Shield: If a new I/O shield is provided, install it into the rear opening of your computer case.
3. Install CPU:
   • Carefully open the CPU socket retention arm.
   • Align the CPU (LGA1150) with the socket, matching the gold triangle on the CPU with the triangle on the socket.
   • Gently place the CPU into the socket without forcing it.
   • Close the retention arm to secure the CPU.

   • 
4. Install CPU Cooler: Apply thermal paste (if not pre-applied) and install the CPU cooler according to its manufacturer's instructions. Connect the CPU fan cable to the 'CPUFAN' header on the motherboard.
5. Install RAM: Open the clips on the DDR3 DIMM slots. Align the RAM modules with the slots, ensuring the notch on the module matches the key in the slot. Press down firmly on both ends until the clips snap into place.
6. Mount Motherboard: Carefully place the motherboard into the case, aligning the screw holes with the standoffs. Secure the motherboard with screws.
7. Connect Power Supply: Connect the 24-pin ATX power connector and the 4-pin or 8-pin CPU power connector from your power supply to the corresponding ports on the motherboard.
8. Connect Storage Devices: Connect SATA data cables from your storage drives (HDD/SSD) to the SATA ports on the motherboard. Connect SATA power cables from your power supply to the drives.
9. Install Expansion Cards (Optional): If using a dedicated graphics card or other PCI-E/PCI cards, install them into the appropriate slots and secure them.
10. Connect Front Panel Cables: Connect the front panel headers (Power Button, Reset Button, HDD LED, Power LED, USB, Audio) to the corresponding pins on the motherboard. Refer to your case manual for specific pin assignments.
11. Connect Rear I/O: Connect peripherals such as keyboard, mouse, monitor, and network cable to the rear I/O ports.

5. Operating Instructions

5.1 First Boot

After completing the hardware installation, connect your monitor, keyboard, and mouse. Power on the system. The computer should perform a Power-On Self-Test (POST) and display the manufacturer's logo or system information.

5.2 Accessing BIOS/UEFI

To access the BIOS/UEFI setup utility, press the designated key during the POST process (typically DEL, F2, F10, or F12). Common settings you might adjust include:

• Boot Order: Configure the sequence of storage devices from which the system attempts to boot.
• Date and Time: Set the system clock.
• System Information: View details about your installed CPU, RAM, and other hardware.

6. Maintenance

• Keep Clean: Regularly clean your computer case and motherboard to prevent dust buildup, which can lead to overheating and component failure. Use compressed air to remove dust from fans and heatsinks.
• Avoid Liquids: Keep liquids away from your computer to prevent accidental spills and short circuits.
• Proper Handling: When handling the motherboard or other internal components, always follow anti-static precautions.
• BIOS Updates: Only update the BIOS if necessary and follow the instructions provided by HP or the motherboard manufacturer carefully. Incorrect BIOS updates can render the motherboard inoperable.

7. Troubleshooting

7.1 Common Issues

• No Power/No POST:
  • Check all power connections (24-pin ATX, 4/8-pin CPU).
  • Ensure the power supply is functioning correctly.
  • Reseat RAM modules. Try booting with only one RAM stick.
  • Reseat the CPU and check for bent pins (refer to Figure 2 for CPU socket caution).
  • Disconnect all non-essential peripherals.
• No Display:
  • Ensure the monitor is connected to the correct video output (onboard or dedicated GPU).
  • Reseat the graphics card (if applicable).
  • Test with a different monitor or cable.
• System Instability/Crashes:
  • Check CPU and GPU temperatures. Ensure coolers are properly installed and fans are spinning.
  • Verify RAM compatibility and stability using memory diagnostic tools.
  • Ensure your power supply unit (PSU) provides sufficient and stable power.
• Boot Device Not Found:
  • Check SATA data and power cable connections to your storage drives.
  • Verify the boot order in the BIOS/UEFI settings.
  • Ensure the operating system is properly installed on the selected boot drive.
• Peripheral Issues:
  • Ensure USB devices are connected to functional ports (refer to Figure 3 for I/O ports).
  • Install necessary drivers for new hardware.

7.2 Clearing CMOS

If you encounter persistent boot issues or incorrect BIOS settings, you may need to clear the CMOS (Complementary Metal-Oxide-Semiconductor) to reset BIOS settings to default. This is typically done by:

• Disconnecting power from the PC.
• Removing the small coin-cell battery (CMOS battery) from the motherboard for 5-10 minutes.
• Alternatively, using a 'Clear CMOS' jumper if available on the motherboard (refer to the motherboard diagram for location).

8. User Tips
