No boot means that the computer isn't functioning as expected and, while lights can be On or Off in the motherboard, no video is display on the screen. No display can also mean no lights (LED) on the motherboard or no video is being displayed to the monitor. Both terms are interchangeable and are used to describe issues in which the computer doesn't start.
If you encounter these issues, try following the tips below.
Click or the topic for details:
Try to clear the CMOS
- Start with the minimal hardware in your system, such as power supply, one DIMM of memory. Connect to internal graphics port (If your processor include the letter “F” in the product line suffix, you need to use external graphics card.)
- Clear the CMOS (complementary metal-oxide-semiconductor). Click instructions on how to clear the CMOS.
If the system worked before, revert changes
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, revert the changes.
If this a new processor, or new DRAM, ensure they are compatible with the motherboard
- If you have a new processor, make sure it's compatible with the motherboard. Refer to How to Find Compatible Motherboards for your CPU using the Intel® Product Compatibility Tool.
- The DRAM should also be compatible. Refer to your motherboard manufacturer's site and the product specification page (ARK) for the CPU to check memory compatibility.
Revert back the BIOS if the issue occurred after flashing it
- If you made any BIOS changes and your system stopped working, revert back to the working BIOS.
- Contact your motherboard vendor for information about reverting your BIOS.
Ensure the processor is installed properly
Ensure the fan heatsink (cooler) is installed properly
- Check if the fan heatsink is installed properly.
Ensure DRAM is seated properly
Other tips to consider
- To see if there's any POST or Beep code, refer to the motherboard manual for Beep code and POST interpretation details.
- Check for visibly bent or broken pins on the motherboard. Physical damage may affect optimum functionality of the processor.
- Check if front panel header connector is firmly plugged into the board.
- Check cable connections for: monitor, power supply, and fans.
- Check the monitor for video input selection: VGA, DVI, HDMI, or USB-C.
