So my new motherboard doesn't have a ps/2 connector, so I bought a Microsoft natural keyboard 4000 to replace my old natural keyboard. But, some of the keys stopped working, so I bought another 4000... which then had different keys stop working.
I tried cleaning them out, but no go. My guess is some condensation or something fell on it and shorted it out... but if it is that easy to short out, I can't imagine how my old keyboard lasted for years. Did I just get unlucky or are newer keyboards more vulnerable? Any recommendations?
