I have a MS Natural Wireless Ergonomic Keyboard 7000. Recently I've noticed that there is a lag when I am typing. It is more pronounced at some times than others. I'm not sure what's causing it but what happens is when typing no letters will show up and then they will suddenly show up but not everything I've typed since the system was obviously not getting everything there are missing characters. Or there will be doubles of a bunch of letters in a row. This happens for no reason I can see. The problem is not a lack of resources this system is loaded. It's a 4770K CPU with 32GB of 2100MHz RAM I'm usually only using about a max of 30% RAM and 5-10% CPU Usage when this is happening.
