I see you're having problems with your wireless keyboard, a few things to
try as I used to get this as well. If you have a decent make/model search
for the latest drivers if you haven't already. Change the batteries as they
may be getting low or recharge if they're that type. Go into Control Panel
and select the keyboard icon, double click it and play about with the
settings to see if that improves things. Can you try it on another PC? Also
what anti-virus software are you running if any? as it maybe causing the
problem. Try disabling that for a few mins to see what happens. Make sure
your wireless receiver for the keyboard is not being blocked or if you can
move it closer. Clean the keys may help. Have you any other wireless
devices? i.e. Router, cordless telephone etc, it could be causing a slight
interference. If none of that works then I'd suspect the boards on it's way
out or it was a cheap crappy one to start with. The one I had was a cheapo
from Tesco, traded it in for a nice Microsoft one.
