Keyboard / Mouse Keyboard @ and" are transposed

Hi all,
I have an Acer Aspire Z5610 AIO computer.When I first bought it a few years back the @ and " were transposed.Hit the @ and " would come up and vice versa.At the time I contacted someone (can't remember who) and with their advice I was able to correct the problem.Due to age the PC was running v.slowly,painfully so.I decide to revert back to Factory default settings,unwisely it turns out,but the old problem of @ and " transposition is back.Has anyone out there got a solution to this problem.It is fixable as I have done it before,but how !!!
Thanks in advance,
Frank.

It's not really a problem particularly as you know which keys to press to get @ or ". This is one of the few differences between UK and US keyboard layouts. You can change the English language version from one of the options in Control Panel.
