I have had a few problems with my computer and I'm leaning towards it being the cmos battery. The first problem I had was that when I turned on my computer all the leds would come on, the mouse would light up, fans would power up, etc , but I would not actually boot. So what I had to do was let it do this for a while, kill the power, start it up again and it would boot. Now I have noticed that my clock is really off. So are these two problems both something that could be caused by a weak cmos battery?
