My computer has no display.
My computer has no power.
My computer is dead.
Try the Online No Boot Wizard.
This page provides information on how to isolate/troubleshoot No Display issues.
Check if you have already tested the items below:
- Most recent change to the computer
- Inspect for physical damage
- Inspect the motherboard LED light
- Inspect the CPU fan
- Check for Processor issues
- Check for Motherboard issues
- Check for Power supply issues
- Check the Display card / on-board display device
- Check the display monitor
- Check the memory / RAM
- Perform BIOS Recovery
- Perform CMOS Battery procedure
1. Most recent change to the computer
If your computer was on a working state before,
check what was the most recent hardware or software change in your computer.
It might help if you can revert back to the past setting or configuration.
Hardware changes may be the latest hardware part you installed
e.g. display card, hard drive, power supply, sound card, etc.
Software changes may be the latest program you installed.
e.g. games, software applications, etc.
back to top  2. Inspect for physical damage
The optimum functionality of the Desktop board may be affected if it has physical damage/s.
If you see signs of physical damage/s on your desktop board, contact us immediately.

back to top 3. Inspect the motherboard LED light
Locate the Light Emitting Diode (LED) light on your Intel® desktop board.
Upon plugging the computer to the wall socket, you should see the LED light glowing
as indication that the board has power.
Do the following if the LED light still glows:
- Perform the BIOS Recovery if both LED light glows and CPU fan spins on POWER ON.
Do the following if the LED light does not glow:
- Check the computer’s power supply
- Motherboard may be faulty. A dead motherboard’s LED will not glow.
back to top 4. Inspect the CPU fan
Locate the CPU fan in your computer.
Upon turning the power ON, you should see the CPU fan spinning as an indication that
the board has power.
Do the following if the CPU fan still spins:
- Perform the BIOS Recovery if both LED light glows and CPU fan spins on POWER ON.
Do the following if the CPU fan does not spin:
- Check the CPU fan for dirt accumulation. Clean the fan.
- Check the computer’s power supply
- Motherboard may be faulty. A dead motherboard’s CPU fan will not spin.
back to top 5. Check for processor issues
A faulty processor may show the same symptom of “no display” during boot up. Check the following:
- Make sure that you are using a compatible processor for your motherboard.
- Try replacing the processor with a known good working processor, or try your processor on another known good working computer.

back to top 6. Check for motherboard issues
A faulty motherboard may show the “no display” symptom during boot up.
Replace the motherboard with a known good working motherboard.
Make sure that the test motherboard that you will use is of the same specification as your Intel Desktop Board.
In case you will use a third party motherboard for testing, consult the motherboard manufacturer for details.
back to top 7. Check for Power supply issues
7A. Make sure that you are using the correct power supply rating
Most computer systems today require at least 350Watts (and above) of power.
7B. Make sure the power is plugged to the wall socket
7C. Make sure the power supply is connected to the board
7D. Replace the power supply with a known good working unit.
back to top 8. Check the display card/ onboard display device
Identify whether you are using a display card or the on-board display device.
Some Intel Desktop Board models do not have the on-board display device.
To identify, trace where your monitor display jack is connected. The photos below will guide you:
Display jack plugged to on-board display.
Display jack plugged to a display card.
If connected to on-board display, you can try the following:
- The monitor jack may be loose. Secure connection.
- Try using a display device adapter card.
- Replace the motherboard.
If connected to a display device, you can try the following:
- The monitor jack may be loose. Secure connection.
- Replace the device with a known good working unit, or
- Test the device in a known good working computer system
back to top 9. Check the display monitor
Do the following tests to isolate if your monitor is causing the problem:
- Try another known working monitor, and check if display is back.
- Try your current monitor on another working computer system.
back to top 10. Check the memory / (Random Access Memory) RAM
Locate the memory on your computer and check the following:
- Ensure that you are using the supported and compatible memory for your Intel® Desktop Board. Refer to Tested Memory.
- Your memory module may be loose. Secure connection by reinserting the memory to the slot.
- Your memory may be faulty, swap with a known working memory.

back to top 11. Perform BIOS Recovery
We have actual reports that proves performing BIOS Recovery on dead motherboards
(as the last step in troubleshooting) fixes the no display issue.
To perform BIOS Recovery, you can either
- Follow the steps here
- Watch the BIOS Recovery video here
back to top 12. Perform CMOS Reset procedure
Follow the steps below to perform the CMOS Reset:
- Turn off all peripheral devices connected to the computer. Disconnect the computer’s power cord from the AC power source (wall outlet or power adapter).
- Remove the computer cover.
- Locate the battery on the board.
- With a medium flat-bladed screwdriver, gently pry the battery free from its connector.
Note the orientation of the “ ” and “-” on the battery.
- Leave the battery out for 15 minutes, for the CMOS to lose the settings.
- Replace the battery in the connector, orienting the “ ” and “-” correctly.
- Replace the computer cover.
- Connect the board's power supply to its AC power source.
- Turn the system back ON and check if display goes back.
