Have you tried call-centre support for companies like Dell, HP, etc? I know the words 'call centre' may not appeal to you, but this may be the only option for you to accumulate some experience. On the other hand you may be able to find a job in a small company in which two jobs are combined into one, so to say. Like an accounts person who also provides IT admin support when required. Something like that, so you can use the experience you already have. What is your non-IT field? If you would like to obtain some skills in PC troubleshooting and support, perhaps you should try the MS certified A+ qualification, which I think is more hardware orientated, or perhaps another one of the the MSCE qualifications that deal with software support. You could also consider the CCNA which would teach you the skills you need to support computer networks. What area of IT support are you interested in? You could also consider the server side of things. Hope this helped.
