So i have a playstation3 that's not updating, (which makes my online games useless) And my ps3's clock keep resetting each time i turn it off. its been about a week and i still cant find a solution, at first i thought it was cause the clock battery was lose, and it was so i plugged it back in hopping to get better results, but the same thing happens again..... ANY HELP?
