Despite trying all of the solutions listed here, nothing worked, so a new mobo has been purchased which I am pleased (and relieved) to say is now working (mostly, still having a problem with major monitor flickering!)
Anyway, thanks all for your help, it was much appreciated.

Should you need any help or just want to hang and chill with us [H]
