I bought my 360 just before the new year, today it's started artifacting after about 30 minutes or so in PGR3, it's roasting round the back of the console too. It's well ventilated so I'm suspecting one of the fans may have died or something. Trouble is, I phoned Game who've told me that I have to go direct to Microsoft, I queried it with them and tried to insist that my contract was with them surely but she still insisted, I then tried Microsoft and after queueing was told that someone would call me back, which so far hasn't happened. Is there anything I can do?
