Mine's now been RMA'd. DHL are picking it up today so hopefully they'll turn it around quickly. After 4 windows reinstall, updates, driver etc etc I came to the conclusion that it's actually broken. The problem was that I bought it from an eBay seller so am relying on the warranty condition that states the manufacture date will be the assumed warranty start date if I have no proof of purchase. Hopefully it'll all come back fixed or replaced next week.
