Today morning I started experiencing this weird problem,
*When trying to type something, if Left-Shift key is pressed the cursor goes left and if Right-Shift key is pressed the cursor goes right.
*If space bar is pressed, system volume gets lowered. *If NumLock is pressed, system volume gets raised.
*Num pad keys 1&4 working as Shift-Key.
Sticky keys is not running. OS: Windows 8.1.
Already tried re-plugging the keyboard and rebooting the system.
Any help would be appreciated!
