What to do when CPU usage is unstable, high or low

First we open Task Manager, and then switch to the CPU ranks, the CPU to occupy the program one by one, to see which CPU program occupied by the CPU suddenly high and low situation. Find a process that takes up CPU instability to end it (not the system process), and if the system process does not end when it is discovered, then the system becomes problematic.

Computer knowledge

System problems include the driver installation is not normal, or the system is the virus Trojan intrusion situation, there is also a situation is the anti-virus software to monitor the computer to occupy a large number of CPU caused by instability.

Solution: First use anti-virus software to kill poison, it is best to reinstall a genuine system, so there will be no system caused by the use of CPU instability. Then in reducing the boot start item, click "Start-run-msconfig-boot", turn off unnecessary startup items, reboot. Now in view there will not be a large amount of CPU and instability suddenly high and low situation.

Of course, there may be a hardware failure, but this possibility is not very large, which also includes hardware drivers, hard drive bad road, and other reasons, it is recommended to install the Driver Wizard to detect all the computer drivers, and then the computer using MHDD scan hard disk to see if the hard drive is bad.
