OMG, you might actually have to pick up a phone and call them! I know this is onerous in this day and age, but...
All joking aside (sorry, I *had* to do it), remember that this is a user-to-user forum. There is no guarantee that Intel Customer Support will respond to or even read each individual posting. Regardless, no one here, even if they are from Intel, is going to set up a warranty replacement. Pick up your phone and make the call.
Phone numbers can be found here: Contact Intel Customer Support. If you're not in the U.S. or Canada, click on the world icon near the bottom of the page and you can specify your region and country and get the local number for calling Intel.
Thanks to you both for your replies. As Mr Pearson kindly suggested, I contacted Intel via online chat and they were actually very good. I have now arranged to have the unit returned and a new one shipped out (all free of charge, and they even collect the unit from my home via DHL).
For those interested, as soon as I mentioned the uncontrollable UNCORRECTABLE error (:)), Intel immediately offered a replacement. They said there is a known problem with an earlier version of the BIOS, which was not regulating the voltage properly. This causes a capacitor on the motherboard to blow. The only fix is to replace the unit. HDD and RAM are unaffected, fortunately.
I now look forward to receiving my replacement!!
