Just after the warranty expired on my Mac computer, it decided it would only start after five minutes or so which was very frustrating,
one of the main reasons I bought a Mac was because I would not have to wait for it to boot up. I have had advice and computer services try to fix it over the years, but it was explained to me it was something I would have to put up with as there wasn't a fix for the problem. I contacted Iain and explained my problem, expecting him to confirm what I had already been told. He arranged to come and take a look anyway. We had a chat about this and that, while Iain pressed buttons, ran stuff through and did things like what computer people do to fix computers. Now surprisingly to me, but not to Iain my computer is just as it was when new.
Iain's service is second to none. He is both polite and professional and I would recommend him to any one. He is not only very knowledgeable, but he's a big chap as well, so that makes him not only a expert, but a expert who knows what he's on about who you shouldn't argue with. Just let him sort your problems out
Thanks again Iain

Iain and I met in classrooms years ago, during his school-days, since when he has become an expert in the mysterious world of computers, about which I know almost nothing, but - thanks to him - I don’t have to.
What I do know is that I have just completed a sixth novel using one. Each book takes at least three years to write and occupies about 85,000 words, together with a lot of research material, character studies and ideas, all of which are stored in a machine Iain maintains.
He is reliable, conscientious and highly competent, but more than that he offers me confidence that whatever foibles my machine may adopt Iain will sort them out.

I used iSG Computing in Retford for a repair to my desktop. The service was fast and efficient and I have had no issues with the computer since.
I would recommend iSG Computing to all who require their service.

We've had our Mac for about five years and Yahoo suddenly decided it wouldn't recognise our browser. Iain from ISG arrived promptly when contacted and soon diagnosed the problem - the Safari browser was outdated. He was able to sort that out very quickly, although it took so long for it to download that he took it away so he could monitor progress overnight. He and it were back the next day with ALL the software updated. I have found the service provided by ISG to be swift and effective and their staff very pleasant to work with.
