The average user usually cannot exactly say what the system interrupts of the processor are, since it is believed that this is something from the realm of fantasy. But now, when a process of the same name loading the system resources appears in the Task Manager, it comes time to think about how to fix the problem. But first, a little about what it is. An explanation of all these processes and methods for correcting the situation in the most accessible language for an unprepared user is offered.
What are system interrupts?
They can be interpreted not as a specific system process, but as a certain indicator in the form of a kind of litmus test, which indicates only that some kind of “iron” device is working incorrectly or does not work at all.
In other words, system interrupts in the same “Task Manager” are the process of checking computer components. Usually the processor load for this process (in the normal state of the computer) does not exceed five percent. If the load rises, we can consider this the first bell indicating that some device is out of order (the hard drive fell in, the RAM slots do not work, etc.). Sometimes system interrupts in Windows 10 or earlier versions of a system are associated with obsolescence, incorrect installation, or lack of device drivers. But this in most cases refers to increasing the load on resources indirectly.
Why do Windows 10 system interrupts load the processor?
Now a few words about the reasons for the increased load. In simple terms, it can be noted that in Windows 10 system interrupts load the processor only for the reason that when detecting functional failures in the health of a component, the processor takes on the execution of commands addressed to the failed devices, since they simply ignore or skip them.
Accordingly, if the device does not work, the CPU and RAM, as they say, drag it all on their own hump. However, you can get rid of this scourge. And it is not always advisable to replace equipment, although in most cases this is the root cause of increased loads.
Initial Equipment Inspection Steps
In order to find out exactly what exactly the failures are connected with, it is recommended to use third-party utilities, not Windows system tools.
However, you can first use this toolkit. In this situation, you must enter the “Device Manager” (devmgmt.msc in the Run console) and disconnect all devices in the list except for the computer, processor and system components, and then look at the CPU utilization level (you cannot disable these three components when under what circumstances, as this may lead to an abnormal termination of work and problems during the system reboot). Next, you just need to turn on the devices one at a time, figuring out which one affects the degree of load.
Interrupt Checker
Tracking system interrupts is much easier if you use the small portable utility DPC Latency Checker (it does not require installation).
To get started, just start the scan. The results will be shown in the field located at the bottom of the main window. There are also troubleshooting tips, but they are sent to the same “Device Manager” for diagnostics there. But only if it is connected with the processor itself or system devices, for a quick solution to the problem, you can try just reinstalling or updating the drivers of the corresponding components.
You can use programs like Driver Booster, which search for and install updates automatically (the user only needs to activate a scan and agree to install updates).
What could be more?
Sometimes the load of interrupts is also associated with some additional system settings. In particular, it is believed that the use of sound effects for old or integrated soundcards can cause excessive load. Indeed, this can also be.
Therefore, in the Windows sound settings on the improvements tab, disable the use of all effects.
Finally, some experts explain the increase in the load of interrupts as being outdated by the BIOS / UEFI primary input / output firmware. Exit - firmware update. With UEFI, this is quite simple, since the update file can be run directly in the operating system environment, after which the update will be installed upon reboot. In the BIOS, this procedure seems a bit more complicated. If there are update settings there, you can use them too, but in most systems you will have to download the desired file initially, and only then run the update, moreover, from the primary, and not the operating system. The procedure, I must say, is quite troublesome, and without special skills it’s better not to do such things, because the whole computer system can simply be completely unusable.
Conclusion
In conclusion, it remains to note that in the event of a RAM malfunction, the Memtest86 + program can be used for diagnostics or the failed brackets can be checked by removing them from the slots on the motherboard. As soon as a bad bar is detected and the system boots normally, the processor load in the form of an interrupt process will instantly and significantly decrease.
In general, each user should clearly understand that in the event of such a situation, the problem is most likely in the hardware, and not in the drivers. Although ... you never know what can happen. And these were only the main causes of failures and diagnostic methods. It is likely that for non-standard computer configurations, assembled manually, you will need to download and use diagnostic programs for each individual device. However, it is recommended to download such applications exclusively from the websites of equipment manufacturers or relevant developers in the form of support services. In the case of laptops, you can use the standard online diagnostic tools that are present on any online resource of a self-respecting manufacturer.
