I know that an Optical Mouse requires no cleaning because it has no Track-Ball as found on the more tradional models. However the Scroll-Wheel on my Optical Mouse no longer rolls smoothly -- it's very jerky now -- how would I go about fixing that? There's no obvious way to get into the innards of my mouse to clean it.
Help, my PC with Windows 10 won't shut down properly
Since upgrading to Windows 10 my computer won't shut down properly. I use the menu button shutdown and the screen goes blank, but the system does not fully shut down. The only way to get it to shut down is to hold the physical power button down till it shuts down. Any suggestions?
