You said you built the machine yourself. Are you sure you plugged all those little header wires that go from your mobo to the various USB ports and switches in your case correctly? They're small, color coded and it's very easy to make a mistake. If they're not all plugged in correctly or you left one unplugged because it's so tight in there that could be something that's throwing a code that Windows Update doesn't like.

We have a huge retail electronics chain in the US called Fry's. If you buy all the components from them they will put the whole system together and install Windows for $85. I usually do it myself but when I found out about that deal I paid the money and let their tech do it. Maybe you have something similar in the UK for the next time you need to build a new system.
