If it is still under warranty, take it in for repairs... if not maybe someone more techy can advise you. Have you run checkdisk? you click on where it says "computer" or "This PC", right click on your hard drive, left click on properties, select tools, then select to run check disk and repair errors. It will tell you that it needs to restart to do that. Restart. It will take 1-2 hours to run but MAY or may not fix your disk read error. If that doesn't work, a tech will have to help ya.
