More Computer Stuff....

If your computer clock starts showing wrong times when you start the computer, that's usually a sign that your CMOS Battery on the motherboard is dying. This is a 3-volt lithium battery about the size of a nickel, but thicker. Usually, it's located near your CPU or between it and your RAM sockets. These usually last about five years, give or take, and you can change it yourself if you are careful. Turn off the power (unplug it from the wall), open the box, and look for a round watch-style battery in a shallow socket on the motherboard. It will probably have a number on it that shows CR2032. It will look like this.....

 Looking at that socket in the picture, there's a little spring-loaded tab at 3 o'clock. Push that outward, away from the battery, to release the battery. When it pops up, replace it, and press the new one down until the latch engages to hold it in place.

While you're in there, use your can of Ultra Duster to blow the dust and dirt out of the fins on the heat-sink on top of your Processor, below its fan. Don't take the fan off, just use the extension pipe on the duster can to reach between the blades, and blow out the dust. Then you can put the cover back on the box, and turn on the power. When first starting up, you'll see some info about your Bios, and it will likely say "Loading defaults.......Press F1 to continue...." So you press F1 and it finishes that, and then shows you your usual login screen. You're back in business again.
