CPU occupancy 100% problem due to hard drive error

Believe that a lot of friends have encountered CPU occupancy rate of 100%, which will cause the system slow as a snail. Half an hour ago, the author is playing a game, the computer suddenly slow, open Task Manager, found that the CPU occupancy rate of 100%, and too much CPU process is not fixed, like a drum to send flowers in the process between the transfer.

My software Environment is: Windows XP SP3 system, open Thunder download, Jinshan poison PA Full defense, Super Rabbit Internet Wizard, two QQ, thousands of listening, the game "too GE aspire to preach Ⅴ".

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.

Summarize:

Computer malfunction, can not always be confused by appearances, as in this case, obviously the CPU occupancy rate continues to high, the problem is only in the disk error. Everyone later encountered similar breakdowns can refer to this article.
