System Interrupts are operating system processes that function as an alert system for the CPU. So whenever a scenario needs the attention of the CPU, it alerts the CPU about it. In turn, the CPU suspends what it is doing, saves it, and then takes care of that important job and once that job is completed, it resumes back to what it was doing. This indicates that although System Interrupts appears as a process, it’s actually not. As a matter of fact, it is like a manager that reports to the CPU about all interrupts that happen on a hardware level, e.g. hardware interrupts. And if there are lots of interrupts, this means that there might be various errors occurring on a hardware level. As a result, it may take a lot of system resources. And if you consider disabling System Interrupts, stop right there as your computer will almost become useless without it.
So if you see System Interrupts consuming high CPU usage in your Windows 10 computer, you can fix it without having to disable it and cause more problems. If System Interrupts takes up more than 5 to 10% of CPU, then you definitely have a problem. This could be happening due to some hardware or driver issue. The first thing you can do is to try rebooting your computer once and see if the issue comes back or not.
High CPU usage of System Interrupts is a huge backlog for the CPU and it stays in the loop. If a simple system restart didn’t fix this issue, here are some suggestions you can try.
As stated, the problem might have something to do with hardware drivers so you can try to update these drivers and see if it works.
Note: On the other hand, if a recent update has caused the System Interrupts high CPU usage, then you might want to roll back your hardware drivers to their previous versions.
You can check with the Windows Update History to check out any recent updates as well as the previous ones.
A lot of users reported that they were able to fix the problem by disconnecting and reconnecting cables and hardware like scanners, printers, cameras can help in fixing the problem. In addition, you can also boot your computer in a Clean Boot State so that you can find the problematic hardware by hit and trial method. Refer to the steps below to do so:
If you do not want to remove hardware, you can just disable them using the Device Manager. Note that this can also be applied to the internal hardware.
Note: Make sure that you disable one device at a time and then give it a couple of minutes and check if there are any changes in the CPU usage to pinpoint the hardware. And if there is no change, you need to enable the device you’ve just disabled and then proceed to disable the next hardware device. If there are changes, then it’s probably the culprit. Just keep in mind that you must no disable any device that is needed to keep your system up and running.
Updating the BIOS/UEFI can help you fix the high CPU usage of System Interrupts but as you know, BIOS is a sensitive part of a computer. Even though it is a software component, the functioning of the hardware depends on it largely. Thus, you must be careful when modifying something in the BIOS. So if you don’t know much about it, it’s best if you skip on this option and try the other ones instead. However, if you are well-versed in navigating the BIOS, then follow the steps below.

"An unknown error has occurred. 0x80040600"If this is the primary source of your communication in the office, then this error can cause you a great deal of inconvenience as it may prevent you from running important business errands via your Outlook account efficiently. Therefore, when you experience the 0x80040600 error on your PC, it is advisable to fix it immediately.
Code 39 is a device driver error code that pops up when the Windows operating system cannot load the driver for the hardware you want to use.
This hampers your ability to use the hardware properly. The error code is almost always presented in the following format:
“Windows cannot load the device driver for this hardware. The driver may be corrupted or missing.” Code 39
A device driver is a software program that tells the operating system how to control a particular hardware device. Each hardware device has a different driver.
There are separate device drivers for printers, CD-ROM readers, and keyboards, to name a few.
Many device drivers are already built into the operating system. But sometimes you will need to install a new device driver when you want to use a new piece of hardware device that the operating system is not familiar with, or does not anticipate.
Regardless of whether or not the drivers are already integrated into the operating system, you may still experience code 39, typically because of the corrupted or outdated drivers.
Outdated and corrupted drivers cause hardware malfunction and failure, which trigger device driver error codes like code 39. Other causes include incorrect registry values.
Below are some of the easiest and most effective methods to resolve Device Manager error code 39 on your PC.
To follow and implement these methods, you don’t require any technical knowledge or expertise. Simply follow these instructions to fix the error right away.
There is a possibility that the error code 39 is caused by some fluke within the Device Manager or your BIOS.
If that’s the reason, then a simple PC reboot can resolve the issue immediately. Therefore, before you try anything, it is advisable to restart your system.
If it works, then that is great, but if it doesn’t, then don’t worry, try other methods given below to fix this problem successfully.
If the error code 39 is generated due to faulty or outdated drivers, then simply uninstall and remove them and then reinstall new driver versions. There are two ways to remove faulty drivers.
This method, although effective in resolving error code 39, can be time-consuming. To avoid the hassle and save time, try method 3.
