Fix 3: Pay attention to motherboard beep sounds

A series of beep sounds may come from your motherboard when you try to power on the PC. You can identify these sounds to diagnose and solve the problem. A single beep sound means everything is working perfectly. Whereas, long and continuous beeps indicate a critical fault with the power supply.

If you do not have the PC’s manual, you can find the necessary information to troubleshoot the issue on the computer manufacturer’s website.

Fix 4: Check your motherboard for error codes

Modern motherboards come with digital displays, showing error codes depicting what process went wrong. You can note the code and search the web to learn how to fix it.

Fix 5: Ensure there is no problem with the power button

A damaged or problematic power button can be the reason your computer fan is running but the device is not turning on. Hence, you can try turning on the onboard button of the motherboard. Since all motherboards are different, you may need to go through your motherboard’s manual to locate the power button.

If you cannot see anything on the computer screen despite the device seeming to be running, there can be a problem with the monitor. Hence, make sure that the monitor is switched on and connected to the PC.

Moreover, ensure the monitor brightness is not accidentally turned down to zero. If possible, you can plug the PC into another display to check if it fixes the CPU not turning on issue.

Fix 7: Let your computer cool down

If you perform a lot of gaming or other resource-intensive tasks, overheating is among the top reasons your CPU is not powering on. Hence, you can wait for the device to cool down before starting it again. Moreover, you can use the best CPU temperature monitor tools to prevent overheating in the future.

Fix 8: Unplug the unnecessary USB devices

USB devices and ports can conflict with the computer, resulting in problems like the CPU not turning on. Hence, you can disconnect all the USB devices and ensure ports are empty when you boot the PC.

Fix 9: Check the BIOS settings

Basic Input/Output System or the BIOS is a low-level program that controls your computer’s hardware. Any issue with the BIOS settings can be a reason the CPU does not power on. Hence, you can follow the below directions to check and correct the BIOS settings.

  • To begin with, press your computer’s power button while holding down the F2/F11/F8/Del key.
  • Secondly, wait until your PC enters BIOS.
  • Now, navigate to the boot menu.
  • Confirm and set your OS drive as your boot drive.

Note: Windows 11 users need to enable secure boot mode and UEFI. You can follow the path Boot tab> Configure (if you have UEFI as the boot mode). If your boot mode is not UEFI, change the mode to UEFI and save the new settings.

Now, you can enable the Secure Boot mode by navigating to the Security tab and switching the mode from Disabled to Enabled. Lastly, save the changed settings and reboot the computer.

Fix 10: Try reinstalling the CMOS battery

You can try to remove and reinstall the CMOS battery to solve your problem. However, ensure you know the battery’s direction (generally, the engraved side has the face-up orientation) before following the below directions to get it reinstalled.

  • To begin with, ensure your computer is off.
  • Secondly, remove all the cords and disconnect all the power sources.
  • Now, open your computer’s cover to view the hardware present inside.
