Top Repair Guide: PC Crashes After Overclocking CPU

Is your PC crashing after overclocking the CPU? In this post on MiniTool Software, I will show you a couple of useful ways with detailed instructions to help you resolve the issue of PC crashes after overclocking CPU.

Is Your Computer Crashing After Overclocking CPU?

Overclocking a CPU usually indicates the process of increasing the CPU’s clock speed by modifying the BIOS settings or using specialized software. The purpose of this is to improve the computer’s performance, especially when running large game programs, video editing software, 3D rendering programs, etc. However, overclocking the CPU can sometimes have the opposite effect and even cause the computer to crash repeatedly.

PC crashes after overclocking the CPU may usually be related to insufficient voltage, computer overheating, outdated motherboard firmware, unstable memory, etc. You can take the following measures to solve this problem. If all other methods fail, you may need to reduce the overclocking settings or turn off overclocking.

How to Fix Computer Crashes After Overclocking CPU?

Fix 1. Increase the Voltage in BIOS

Insufficient voltage when the CPU is overclocked may cause the computer to crash or cause some other errors. If you are experienced enough, you can try to enter the BIOS, go to the OC (Overclock) or Advanced CPU Configuration section, and slightly increase the CPU Core Voltage or CPU Voltage parameters.

Fix 2. Make Sure the Computer Is Not Overheating

Overclocking the CPU will cause the CPU to generate more heat. If the computer overheats, it may crash or automatically restart. You can check if this is your case, if yes, you can take some measures to effectively increase the heat dissipation of the computer. For example, you can upgrade the CPU cooler, add case fans, lower the room temperature, etc.

Fix 3. Check for Memory Issues

Memory may also be one of the reasons for system crashes. You can use the Windows Memory Diagnostic Tool to check for the memory issues. If there are some errors with the memory, you can repair it according to the test result.

Step 1. Press the Windows R key combination to open Run.

Step 2. Type mdsched and click OK.

Step 3. When you see the following window, choose to restart now or the next time to check for memory issues.

Fix 4. Update BIOS

If the BIOS firmware is outdated, your motherboard may behave unstable when overclocked. This may cause the problem of PC crashes after overclocking CPU. In this case, you can choose to update the BIOS firmware to improve system stability.

Tips:

To avoid unexpected situations, it is recommended to back up important files with MiniTool ShadowMaker before updating BIOS. Moreover, you need to make sure that the power supply is stable during the BIOS update process.

To update BIOS, you need to download the BIOS update files from the official website of your motherboard and unzip it. Next, double-click the downloaded program file and follow the setup wizard to complete the BIOS update.

Fix 5. Turn off CPU Overclocking

If all the ways above fail to work, you can go to BIOS and reduce the overclocking settings to check whether it helps. If not, you may consider turning off the CPU overclocking completely. I will show you how to stop CPU overclocking without going to BIOS below:

Step 1. Open the Control Panel by using the Windows search box.

Step 2. Select Hardware and Sound > Power Options.

Step 3. Click Change plan settings next to the power mode that is selected. In the new window, hit Change advanced power settings.

Step 4. In the pop-up window, scroll down to double-click Processor power management > Minimum processor state. Next, change its setting percentage to 99%. Repeat this process to change the percentage for Maximum processor state to 99%.

Step 5. Click Apply and OK to save this change.

Step 6. Finally, it is recommended to uninstall any kind of overclocking software you’ve installed from the Control Panel to ensure that the overclocking is disabled completely.

Windows Data Recovery Software Recommended:

Repeated system crashes may cause some files to be lost. If you face this dilemma, MiniTool Power Data Recovery can be of great help. It is good at recovering deleted or existing files from various data loss scenarios. It is worth mentioning that its Bootable Edition supports recovering files from unbootable computers.

Bottom Line

If your PC crashes after overclocking CPU, you can implement the ways listed above. If any of these methods are difficult for you, you may need to seek help from a computer professional.
