Computer Turns Off / Shuts Down Automatcially

At times your system may turn off without warning, with-in a few minutes after it’s turned on. You may also get a popup which will prompt you to run the chkdsk. This might be because of some corrupt files or hard disk.
Chkdsk is an utility that will help you verify and fix if there are any errors related to files / folders / hard drive. Every Windows user sould make it a regular habit to run the ChkDsk command line utility once every fortnight. This ensures that all your files are intact and also helps in improving the performance of your Windows based PC / Laptop.

At times, your system might turn off abruptly because of a power failure or a virus that shuts your system without you initiating the shut down process. In such cases, the system will auto run-the chkdsk process when the system restarts, and the process looks somewhat like this :
If you want to manually run chkdsk command, then follow these steps:

1> Click Start –> Run –> type cmd –> click OK

2> A command prompt opens, type in chkdsk c: /f /r . In the command, /f command will automatically fix the errors if there are any and /r command locates all the bad sectors and recovers readable information from there.

Once the chkdsk command is completed successfully, restart your system and your system will perform faster and better.
