CPU Footprint 100% What's the reason for the hardware analysis?

Experienced CPU occupancy rate of 100%, resulting in slow system. Open Task Manager, find CPU occupancy rate of 100%, and the process of excessive CPU consumption is not fixed, like a drum to pass the flowers in between the process.

Troubleshooting steps are as follows:

After killing, the system is not in the virus. Next, I will disconnect the network, with the ice blade will include Jinshan venom and Explorer.exe, including the non-system must process all shut down. At this point, you open Task Manager and discover that the number of CPUs following the System Idle process in the Processes tab beats around 90. Indicates that the CPU is idle at this time, but the computer is still slow and the CPU occupancy rate is still 100%.

Tip: System Idle process processes occupy high CPU resources, not clear friends don't worry, the process indicates that the CPU is idle, which means that it is the higher the better.

In the helpless, I suddenly think of a few months ago due to hard disk partition table failure to repartition system. Although the software test results show that my hard drive health is good, but for a 80GB hard disk, three years to download, delete more than 500GB of data, how many people do not trust it, so I did a reload system before the last effort ...

Because suspicion is the problem of hard disk, I first checked with the software, the conclusion is no bad way. Then click "Start" → "Run", type "cmd", enter, open a command Prompt window. And then a scan of the hard drive, since the D computer failed to run the program from the C, D, e three partitions, so I entered the "Chkdsk x: R" (where x represents the letter, the author needs to scan three partitions, so x for C, D and e) carriage return. The next two consecutive query options, select "N" and "Y" (pictured), restart the computer.

Tip: For the parameter "/R" that follows Chkdsk, it represents errors on the repair disk and looks for incorrect sectors and restores readable information. At the command prompt, for commands that are not clear to you, you can add the argument "/?" after the command. To view Help on this command.

Then the computer restarts, ScanDisk scan the disk after the end of the raid, again log on to the system, and found that the system is running flying.
