I can just see it now -
User - Hello my new motherboard that i bought the other day for my PC is not working, it seems to overheat then switch off, the board looks warped, can i have an RMA number please.
Tech support - You dont need an RMA just yet, what we need to you to do is wrap it up in a towel so it is completely smothered, switch it on for half an hour and that should sort the issue.
User - Hello did I just ring PC world by mistake?
