If your BIOS shows a facility named SMART, let that check the disk. If not, you need to take the hard disk out and slave it to another machine then run the Checkdisk facility.
Press your Windows key and R together then type in cmd and press Enter. At the Command Prompt, use the syntax
chkdsk x: /r
where x is the drive letter assigned by the computer to that disk. The /r switch gives you the chance of having any disk errors fixed.
