I would like to contact Intel Customer Support, so that I can have my mobo replaced/repaired.
I can't contact them through the website as the mobo has been marked EOIS but is still in warranty.
Here is the full address:

Branded Products Support Centre
Intel Corporation (UK), Ltd.
Pipers Way
Swindon, Wiltshire
England SN3 1RJ

Here is their non-geographical number: 0870 607 2439

In response to Jim_H's post today (to be merged with this thread) I just called Intel on 01793 403 000, prefixed with 141, and asked for spare parts.  The operator started saying that there was a different number but only got through the first couple of words before she said she will put me through and did. Probably the 141 prefix did the trick.

By the way, I was ready to tell them that I was calling from abroad but it did not come to it.
