Question:

I’m encountering a persistent ‘no display’ issue with my computer setup, which includes a Gigabyte B760 Aorus Elite AX DDR5 5600 motherboard paired with an i5 13600K processor and an M.2 SSD. The system is powered by a Corsair RM750x V2 PSU from 2018. Upon booting, the computer powers on without any display signal, the motherboard’s LED lights remain off, and the keyboard momentarily flashes alongside some lightning effects.

Initially, the setup functioned flawlessly, but upon returning home, the ‘no display’ problem resurfaced. Notably, this PSU, which has been in use since 2019, has previously exhibited ‘no signal’ issues when used with a different configuration involving a Gigabyte Z590 UD AC motherboard and an i5 11600K CPU with DDR4 3200MHz 32GB RAM.

Could you provide insights into the potential causes of this issue and suggest troubleshooting steps to resolve it?”

Answer:

When faced with a ‘no display’ issue in a computer setup, it’s essential to approach the problem methodically to identify and resolve the underlying cause. The situation described involves a high-end PC build with a Gigabyte B760 Aorus Elite AX DDR5 5600 motherboard, an i5 13600K processor, and an M.2 SSD, all powered by a Corsair RM750x V2 PSU from 2018. Despite initially functioning without issues, the system now fails to display anything upon startup, with additional symptoms including non-responsive motherboard LED lights and a flashing keyboard.

Potential Causes

The ‘no display’ problem can stem from various sources, which may include:

1. Power Supply Unit (PSU) Issues: Given the PSU’s age and previous ‘no signal’ problems with another motherboard, it’s plausible that the PSU is failing to deliver stable power to the components, especially under load.

2. Motherboard Faults: The motherboard could have developed a fault, potentially in the BIOS, which may require resetting or updating.

3. Graphics Processing Unit (GPU) Errors: If a discrete GPU is in use, it could be improperly seated, or its power connectors might be loose or damaged.

4. RAM Incompatibility or Failure: The DDR5 5600 RAM might be incompatible with the motherboard’s current settings, or a RAM stick could have failed.

5. Peripheral Issues: Occasionally, peripherals like the keyboard can cause startup issues if they malfunction or short circuit.

Troubleshooting Steps

To address the ‘no display’ issue, consider the following troubleshooting steps:

1. Inspect the PSU: Test the PSU with a multimeter or a PSU tester to ensure it’s providing the correct voltages. If possible, try a different PSU to rule out power-related problems.

2. Check the Motherboard: Look for any visible damage on the motherboard. Clear the CMOS to reset the BIOS settings to default, which can sometimes resolve display issues.

3. Examine the GPU: If using a discrete GPU, reseat it and check all power connections. Test with another GPU if available.

4. Test the RAM: Try booting with one RAM stick at a time to identify a potential faulty module. Ensure the RAM is compatible with the motherboard’s specifications.

5. Disconnect Peripherals: Unplug all peripherals, including the keyboard, and try to boot the system to see if the issue persists.

6. Monitor and Cable Check: Verify that the monitor and cables are functioning correctly by connecting them to another computer.

If these steps do not resolve the issue, it may be necessary to consult with a professional technician or reach out to the component manufacturers for further assistance. Remember, when dealing with electronic components, always take appropriate safety precautions to avoid electrostatic discharge and other potential hazards.

In conclusion, a ‘no display’ issue can be frustrating, but by systematically checking each component and connection, you can often pinpoint the problem and find a solution. Good luck!
