So yeah I got them
This is annoying because I understood that the 360 has had some teething problems (hardware wise) and so I read some blogs/reviews and followed their advice of keeping it verticle (spelling?) and in a well ventilated area to try and remove the chance of getting hardware problems but I guess it means nothing.
I was wondering if anyone else has had this problem and if they had managed to fix it without breaking waranty or sending the console back to MS?
