What you need to do, my friend, is replace the CMOS battery as the one that's on your motherboard has lost it's ability to hold charge.
Unless you have a particularly old computer, and I don't believe that you do as your BIOS/CMOS date is resetting to 2005, the battery will most likely look like a large watch-type battery. (It will have a few letters and numbers inscribed on it. The most common ones have CR2032 inscribed on them, but some motherboard manufacturers MAY have used a different one.)
They're not expensive, and can be bought at just about any computer store.
