Rule of thumb for myself, and seems to work for myself, and that is doing a BIOS update/upgrade. Usually when a new BIOS comes out, it usually (99.999%) gives your PC new features that were not enabled when the computer was released into the retail chain. To update your BIOS, just go into your BIOS, and there will be a feature that tell you to "Upgrade your B.I.O.S." and it is a button, just click it, and watch the magic. BTW, you have to be connected online, and during the BIOS upgrade, you should be on your knees praying that there isn't a power outage. NOT KIDDING: has happened to me in the past, and those BIOS weren't self healing, and the whole motherboard had to be replaced, BIOS chip was soldered on.
