[Solved] CPU Randomly Spikes to 100%

The CPU randomly spikes to 100% for no apparent reason.

The cpu spikes while gaming is a problem that has been present for a while. There are many fixes to solve the issue, but they vary depending on the game you’re playing.

If your machine is operating well, you may overlook the sudden increase in CPU use to 100% and then return to normal. Random CPU consumption is typical with Windows. However, something may be wrong if your computer slows or freezes. In this instance, you may be interested in learning how to resolve this vexing problem. I’ll teach you how to solve the problem in this article.

You have five options for resolving the “CPU randomly spikes to 100%” problem. You may try each one separately until your computer’s performance problem is fixed.

Method 1: Make sure your drivers are up to current. Method 2: Scan for viruses or malware. Method 3: Do a thorough boot cleaning. Method 4: Examine your power choices Update the BIOS (method 5)

Method 1: Make sure your drivers are up to current.

Your CPU may unexpectedly spike to 100% due to faulty or unauthorized drivers. You may try upgrading your drivers, particularly your graphics card drivers, to resolve the problem.

You may update the drivers manually or automatically. The most essential thing is to make sure you get the drivers from the manufacturer’s website, which has been validated by Microsoft.


If you don’t have the time or computer skills to manually update your drivers, you can do it using Driver Easy, which enables you to do so in just a few clicks. Driver Easy also installs drivers from the manufacturer’s website that have been validated by Microsoft.

Here’s how to update drivers using Driver Easy.

1) On your computer, download and install Driver Easy Free.

2) Open the program and choose Scan Now to identify any problematic drivers on your computer; you’ll then be presented with a list of drivers that may be updated.


3) Next to a driver, click the Update button, and the driver will be downloaded immediately. After the download is complete, follow the Driver Easy step-by-step instructions to install the driver (you can do this with the Free version). If you have the Pro version, you may use the Update All button to automatically update all drivers.


Method 2: Run a virus or malware scan on your computer.

If your computer is infected with a virus or malware, the CPU utilization on your computer may increase at unexpected times, causing lag. It is suggested that you perform a virus or malware scan on your computer to resolve the issue.

You may accomplish this by installing a decent antivirus or antimalware program. Run a thorough scan on your machine using the program to identify any viruses or malware. If you’re not sure what software to trust, the well-known MalwareBytes program may be your best bet.

Method 3: Do a thorough boot cleaning.

It’s quite possible that an application is running in the background, using the majority of your CPU, and you’re not even aware of it. You may try doing a clean boot to resolve the issue. A clean boot may assist you in determining if the problem is caused by a third-party application service or starting software. To do so, follow these steps:

1) To open the Run box, press Win+R (the Windows logo key and the R key) at the same time on your keyboard.

2) In the Run box, type “msconfig” and click OK. The System Configuration window will appear after that.


3) Select Selective startup from the General menu, then uncheck Load startup items.


4) Select Hide all Microsoft services from the Services menu and click Disable all.


5) Select Open Task Manager from the Startup menu.


6) Select the item you want to deactivate upon startup in Task Manager and click the Disable button. Rep this process until all starting items have been disabled.


7) Return to the System Configuration dialog box.

8) To save the changes, click Apply -> OK.

9) Check to see whether the high CPU problem is still present.

Third-party services or applications may be the source of the problem if it is addressed. You can then figure out which services or applications are causing the problem. Take the following steps:

1) Return to the System Configuration window.

2) Navigate to the Services tab.

3) At the same time, enable a number of non-Microsoft services (for example, five services as a group).

4) Check to see whether the issue still exists.

5) Go through Steps 3 and 4 again until you identify a set of services that are causing the problem. Then go through each one one by one until you identify the one that’s creating the problem.

If none of the services are the issue, repeat the procedures for Startup programs to determine which startup program is causing the problem.

Method 4: Examine your power choices

Make sure the High performance mode isn’t chosen in your power choices. To do so, follow these steps:

1) Re-open the Run box.

2) To enter the Power Options window, type “powercfg.cpl” into the Run box and press OK.


3) Determine what power plan your machine is currently utilizing. Make sure that the High performance option is turned off. If it’s enabled, you may choose between the Balanced and Power Saver modes.


Update the BIOS (method 5)

If none of the other ways work, updating the BIOS is your final option for resolving the problem.

1) Go to the manufacturer’s website for your motherboard.

2) Go to SUPPORT and look for your motherboard model (How do I know what motherboard model I have?).

3) Install the most recent BIOS on your machine.

4) Set up your BIOS. The procedures for installing BIOS varies based on the brand of device. If you’re unsure how to proceed, see the product handbook or contact the manufacturer for instructions.

IMPORTANT: Incorrect BIOS updates may result in severe system problems. Make sure you understand what you’re doing. If not, you may need to get help from a technical support team.

With the methods above, you should be able to resolve the “CPU randomly spikes to 100%” problem. Please leave a remark below if you have any queries. I’ll get back to you as soon as possible.
