You won't void the warranty or anything like that though. When your computer is booting up, get into the BIOS menu. Look for something called Native SATA. I don't know which menu it's in though. This problem occured about 6 months ago, but if it is enabled then disable it. If it is disabled, then enable it.

Hope this works for you, it worked for me.
