If the above methods are not helpful enough, here are some more alternatives that you might want to have a try:
1) Uninstall antivirus programs. Check to see if some of your antivirus program is causing this problem. Users have reported that the problem is gone when they uninstall Norton and AVG. You should check if this is help.
2) Change BIOS settings. Some users report that by changing the SATA controller to AHCI on BIOS settings do the trick. But please do not attempt to use this method unless you are well aware of what you are doing since faulty changes in BIOS settings could cause revocable errors to your computer.
