High CPU usage can be a symptom of a number of PC conditions, such as insufficient or bad memory, viruses or malware producing a lot of background activity, insufficient hardware capacity to run all the software you are trying to run simultaneously, or a highly fragmented or corrupt system elements. Whatever the reason, high CPU usage is usually an indication that computer maintenance is due.
This condition may be fixed with special software that repairs issues, tunes up system settings and optimizes CPU consumption.

Symptoms of high CPU usage

When CPU usage on a PC is getting close to 100%, there are normally many symptoms telling the user there is an issue. The PC will usually slow down considerably and may completely freeze for brief or even extended periods of time. The processor may start to overheat. Applications or the operating system itself may end up crashing and a reboot may be required.

Causes of high CPU usage

If CPU usage on a PC is getting close to 100%, it is an indication that there is something going on in the background that is consuming too much processing power. The background activity may be produced by a virus or malware, by hardware specs being too low for the resource-heavy software the user is trying to run, as well as by system elements having too many invalid entries and broken shortcuts. Such entries cause the system to produce too much activity if, for instance, an application or component is not found at the location pointed to by system entry, or if a key is corrupt and cannot be processed correctly.

Ways to repair high CPU usage

The first thing that needs to be checked is the amount of RAM a PC has, to exclude insufficient memory as a possible cause of high CPU usage. Scanning the PC with antivirus software will help eliminate virus activity as a potential reason for high CPU consumption. Once these factors have been ruled out, the next step is to check system elements and clean them up from invalid or corrupt entries. Advanced PC users may be able to edit system elements manually using the regedit tool in Windows administrative tools. However, since any manipulations with system elements carry a risk of rendering the operating system unbootable, whenever a user is in any doubt of their technical skills or knowledge, they may use special software that is meant to repair system elements without requiring any special skills.
