|Note||This guide only applies to the system installed on Intel® Boxed Desktop Processors.|
No boot means that the computer isn't functioning as expected and lights can be On or Off in the motherboard but still no video display on the screen. No display could mean no lights (LED) on the motherboard, or also means no video is being displayed to the monitor. Both terminologies are interchangeable and can describe no boot or no display issues on the computer.
Use the questions below to troubleshoot No Display or No Boot issues. If the problem persists, contact Intel Customer Support or your point of purchase to get a replacement.
Begin by restarting your system. Press the power button for a few seconds until the system reboots. Most motherboards power-on self-test (POST) or beep when there's a booting issue. If that is the case, refer to the motherboard manual to interpret.
Click or the topic for details:
Is your system new?
- If you're using a new system build, boot using the minimum number of components. For example, you might use one memory module and the processor.
- If you have a new processor, make sure it's compatible with the board.
- Check for visible bent or broken pins on the motherboard. Physical damage may affect the optimum functionality of the processor.
- Check if front panel header connector is firmly plugged to the board.
Did your system work before?
- Determine if there have been any recent changes. Often if a change is made, that recent change is the cause of the problem. If there were any hardware changes, reverse the changes.
- If you made any BIOS changes and your system stopped working, we recommend contacting the vendor of the motherboard.
Is the processor compatible with the motherboard?
- The Intel® Processors and Boards Compatibility Tool to make sure the new processor is compatible with your board. The compatibility tool also determines if the new processor requires a specific desktop board or BIOS version.
- That the memory sticks installed in your system are compatible with the board and the processor.
Is the LED light off, not visible on the motherboard, or outside the case near the power supply?
- All power cables. Ensure they're plugged into the outlet and into the computer.
- The power outlet to ensure it's working properly.
- That the power switch on the computer is on.
- Power supply issues.
Is the LED light on, visible on the motherboard, or outside the case near the power supply? Does it indicate power but show no display?
- All the fans are connected and spinning.
- All venting is clear of obstructions. If the processor overheats, the system doesn't boot.
- The monitor power cables are plugged in and the monitor is on.
- The video cable or cables are connected properly at the monitor and to the computer.
- The monitor for video input selection: VGA, DVI, HDMI, or USB-C.
Does your system still have no boot or no display?
- To see if there's any POST or Beep code. Refer to the motherboard manual for Beep code and POST interpretation details.
- And clear the CMOS (complementary metal-oxide-semiconductor). For no boot or no display issues, clearing CMOS may help recover the boards because it restores the BIOS default settings.
- You have any memory sticks seated properly. Start with one memory stick and insert it into the first channel. Refer to the motherboard manual for proper memory location.
- You have the processor seated properly. You may need to remove and reinstall the processor. Also check that you have the heatsink installed properly.
- You have properly applied thermal paste.
