CPU is the brain of a computer, so it must be kept in good shape.
CPU usage usually hovers around 3-5 percent, but there may be times when it creeps up at alarming levels. CPU usage gives a reflection of load on the system processor. Higher CPU usage means higher load on microprocessors and RAM, which might result in slow system performance, frequent system hangs and system crash.
Ways to Reduce CPU usage
Everything that’s executed within a system adds to the load of CPU (processor); programs, system processes all contribute to it. There are many unnecessary things that pile onto the CPU and overloads it. Here is how you can bring it down,
- Kill unnecessary system processes that’s not required, or consumes more memory and overloads the CPU. Press Ctrl>Shift>Esc to open Task Manager, select the process and end it. Be cautious in killing processes as you might, unknowingly stop any important system files from operating.
This should heavily bring down CPU usage. If not, execute the next step.
- Prevent programs to run at system startup. Except a few programs like system drivers and antivirus, there is no need to run most programs on system startup. Users can open it directly whenever required, no need to pre-fetch programs and store in cache for faster startup.
- If you’re CPU usage is still high then you need to take a closer look at if any Virus, Trojan, spyware or worm in there in the system. They’re designed to modify or destroy system data consuming bulk system resources. Keyloggers might have been installed to track your activities, which is a very heavy program. You can check this by updating antivirus, then running a scan and removing any potential dangers found by it.
- Update drivers, Switch off WiFi when not required, Remove useless stuff from desktop, manage desktop GUI etc to reduce load on CPU and minimize memory use. Also, keep system as cool as possible, avoid overheating.
