What to Do When Computer Won’t Turn On But Has Power

If your computer won’t turn on but has power, it can be frustrating. You may feel like you’re doing everything wrong and may not know what to do. If you are facing such an issue, don’t panic! There are a few things you can do to try and fix it.

In this blog post, we will help walk you through some of the most common reasons why your computer isn’t turning on and how to fix it. We will also provide some tips to help prevent this from happening in the future.

Why Won’t Computer Turn On Despite Having Power?

There can be a few reasons why your computer won’t turn on even though it has power. Here are the most common ones:

  • Not enough power: Your computer may not be receiving enough power to start up. Make sure the outlet you are plugged into is working and that all of your cables are secure and properly connected.
  • Faulty hardware: The components inside your computer, such as RAM or hard disk, can sometimes fail, causing it to not start up properly.
  • Software conflicts: If your computer’s software is corrupted or there are conflicts between programs, it may not be able to start up properly.
  • Corrupt operating system: This can be caused by a virus, malware, or recent changes to your OS. You may need to reinstall the OS or reset it using recovery tools.
  • Discharged CMOS battery: The CMOS battery is the small, round battery inside your computer that stores information about BIOS settings. If it has run out of charge, then your computer won’t be able to start up.
  • Overheating: If your computer is overheating, it may be preventing it from starting up. Make sure your fans are running and that there is good airflow in the area you are using the computer.
  • Incompatible peripherals: If you are using external devices such as a printer or USB drive, they may be preventing your computer from starting up.

Fix 3: Check the Motherboard Functioning


If the computer has power, but you won’t see it turning on, then it could be due to a faulty motherboard. To verify if that is the case, you can disconnect all the cables and power sources from your computer and then hold down the power button for a few seconds. If nothing happens, it could mean that your motherboard is not functioning properly.

Fix 4: Check the RAM and Processor


If your computer won’t start up, it could be due to a RAM or processor issue. To check this, you can take out the RAM and power cycle your computer by unplugging it and then plugging it back in. Other than that, you can also take out the processor and try to start it up again. If that doesn’t work, you may need to replace the RAM or processor.

Fix 5: Reset BIOS Settings

If there are conflicts between software programs or if your OS is corrupt, you may need to reset your BIOS settings. This can usually be done by pressing the F2 or Del keys while your computer is booting up. You’ll then need to enter the BIOS setup screen and find the option for resetting all settings to their default values.

1. Press and hold down the F8 key while your computer is starting up.

2. When you get to an options screen, select the “Enable Safe Mode with Networking” option by using your arrow keys.

3. Your computer will then be booted into Safe Mode, where you can troubleshoot further.

Fix 7: Check Your Monitor Screen

If your computer is not displaying anything, it could be due to a faulty monitor or monitor cable. To check this, you can try connecting the monitor to another computer and see if it works. You can also try unplugging the monitor from your computer and plugging it back in.

Other than that, it is also possible that the monitor cable is damaged, so you should check the condition of the cable before taking any other steps.

Fix 8: Pay Attention to Beeps

If your computer is beeping, it could be due to a variety of issues, such as loose RAM, a damaged video card, or a motherboard. If you can identify the type and number of beeps it is making, you may be able to pinpoint the problem. The pattern of beeps can usually indicate which component needs to be replaced in order for your computer to work. To decipher the beep pattern, it is advised to contact a professional.
