Keyboard doesn't work!!! :(?

Do you have another keyboard? or do you have the cd for the one you have now? if so install it again. or unplug it shut down computer and plug it in and restart your computer. some keyboards like mine have refresh, power,sleep,wake up ETC, ETC Im just hoping it works for you this has happened to me before i keep messing with it till it finally runs again. Id consider a new keyboard hey Walmart is open all night if you cant get it going and it sucks when you gotta mess with it over and over. I wish you the best i have faith in you, you will get it. Thanks And Star. ps. just trying to help as im far from an expert with computers. xo
