My keyboard suddenly started having trouble with the shift key. The caps lock works, but trying to capitalise letters with the shift key only works for some keys (Specifically, Not working means nothing is produced). The strange thing is that when keys work depends on if I am holding down the left or right shift.
No idea if this is a software or hardware problem.
I have tried different USB ports, restarting, and uninstalling and reinstalling the keyboard driver. All to no effect.
