Fix NT Kernel & System Process CPU Usage in Windows 7. I recently ran into a strange problem where a process called System (NT Kernel & System) was using about 1. CPU on my Windows 7 machine all the time. In the above screenshot, System is using 0 percent CPU, which is how it normally should be. The system process basically houses the kernel and driver code plus system threads and is an essential Windows process. Don’t try to kill the process or remove it. Before getting into any technical details, this problem is usually caused by a bad or outdated hardware driver in Windows. There are a couple of things you want to check immediately: New Hardware – Did you recently install any new hardware on your Windows 7 machine? Graphics card, hard drive, sound card, TV tuner card, etc? If so, you need to go to the manufacturers website and download the latest driver from there. If you only installed the driver from the CD that came with the new hardware, it may be out of date. ![]() Updated Driver – Did you recently update a driver and are seeing the higher CPU usage after the update? Sometimes the latest drivers may also cause problems. ![]() In this case, you should try to roll back the driver and see if that fixes the problem. In my case, I had installed a new graphics card on my PC and installed the driver from the CD. It wasn’t the latest driver and since it was a kernel mode driver, it was causing this spike in the System process. If you can’t figure out which driver is causing the issue, there is a more technical procedure that you can follow to find the exact problem driver. First, download a program called Kr. View (Kernrate Viewer), which is a free tool from Microsoft. It’s a command line tool, so open a command prompt and then just run the program without any arguments.

DLL is the driver for the Broadcom Net. Xtreme Gigabit Ethernet card. Now you just need to go and find the updated driver for the network card and hopefully the spike in the CPU will go away. Of course, the other solution in this type of case is to simply disable that piece of hardware or remove it from your system completely if you don’t need it or can’t find an updated driver. Why is my CPU running at 1. The average Windows PC is permanently busy, constantly juggling system resources between the 5. Sometimes, for no apparent reason, a rogue application will demand all your processor's attention, and before you know it the process is running your processor at 1.
