PC Turns On No Beep No Boot Fix – New Build Issue

I recently encountered a common issue with my new PC build – it turns on with no beep and no boot. This article will discuss how to fix this problem.

Understanding POST and Beep Codes

When your PC turns on but you don’t hear any beeps or see it booting up, it can be a frustrating issue with a new build. One possible reason for this could be a problem with the Power-on self-test (POST) process.

POST is a diagnostic testing sequence that your motherboard goes through when you turn on your computer to check if all the components are functioning correctly. If there is an issue, the motherboard usually sends out beep codes to indicate what the problem might be.

To troubleshoot this issue, it’s essential to understand these beep codes and what they mean. Different motherboard manufacturers like Asus may have different codes, so it’s important to refer to your specific motherboard manual for accurate information.

Look for any error messages on your computer monitor, and check if all the components like the CPU, RAM, and graphics card are properly seated. Make sure all power cords and connectors are secure, and try reseating the components if necessary.

If you’re still having trouble, consider using a test card to diagnose the issue further.

Troubleshooting Connection and Power Issues

  • Ensure power supply is properly connected to motherboard and components.
  • Check power supply switch is turned on.
  • Test power supply with a multimeter to ensure proper voltage output.

Inspect RAM

  • Reseat RAM sticks in their slots.
  • Try using one stick of RAM at a time to isolate faulty module.
  • Clean RAM contacts with rubbing alcohol and let dry before reinserting.

Check CPU

  • Ensure CPU is properly seated in the socket.
  • Check for bent pins on the CPU socket.
  • Apply thermal paste and reattach CPU cooler.

Testing and Reinstalling Hardware Components

Next, test the components: Start by removing all unnecessary hardware components, such as USB devices, extra RAM sticks, and additional hard drives. Power on the PC to see if the issue persists. If the PC turns on but still does not beep or boot, proceed to the next step.

Test each hardware component individually: Begin by testing the RAM sticks. Remove all but one and try booting the PC. If it does not work, try a different RAM stick in a different slot. Repeat this process for the graphics card, CPU, and any other hardware components.

Reinstall the hardware components: Once you have identified the faulty component, reinstall it properly. Ensure all connections are secure and that the component is seated correctly in its slot. Power on the PC to see if the issue has been resolved.

Resetting BIOS and Recovering Data

To reset the BIOS and potentially recover data on a PC that turns on with no beep and no boot, follow these steps:

1. Turn off the computer and unplug the power cord from the power supply unit.

2. Locate the CMOS battery on the motherboard – typically a round, silver battery.

3. Carefully remove the CMOS battery using a small tool or your fingers.

4. Wait for about 5-10 minutes to allow the BIOS settings to reset.

5. Reinsert the CMOS battery back into its slot on the motherboard.

6. Plug the power cord back into the power supply unit and turn on the computer.

If the issue persists after resetting the BIOS, it may be necessary to seek further troubleshooting or professional assistance to recover any data or resolve the boot problem.


Why is my computer not beeping when I start it?

Your computer is not beeping when you start it because there may be Power Supply Unit errors. Check the cords and PSU to ensure they are working properly and try disconnecting any unnecessary wires or UPS from the computer.

How do I fix my computer not beeping and turning on?

To fix a computer that is not beeping or turning on, you can try reseating the RAM and dusting the video card. Additionally, checking the PC to HDD connection and making any necessary changes may help resolve the issue.

Should a computer beep on startup?

A computer should beep on startup to provide the Power-On Self-Test (POST) result.

Is my computer supposed to beep?

Your computer is supposed to beep when it is booting normally. However, if you are hearing continuous beeping or a different pattern of beeps, it could indicate a problem with the memory or another hardware issue. Try resetting the BIOS to see if that resolves the issue, but if the problem continues, you may need to replace the memory.
