I have been having a problem for the past year or so with my keyboard. It happens about once a week. I will be typing, and all the sudden, it will not work. The mouse works, but the keyboard will not. The only keys that work when this happens are the 'control' 'alt' 'delete. None of the other keys work. If I log off and log back on, everything works again. I have tried reloading and rteinstalling the driver. That didnt help. Has anyone seen a similar problem before? At this point its just more of a nuisance than anything else and Im curious whats causing it. Thanks.
