Hi, My xbox is getting really bad with freezing issues which I take it are due to over heating! Some times when I have played it a while, and I switch it off then back on, the video signal will come back on scrambled (fuzzy lines across the screen) or even nothing at all(no picture will show on screen - no red circle on front of console). When I switch it off and leave it a while, then restart it will startup fine. So I was thinking of buying these from ebay.co.uk Item number: 180080603499 Has anyone installed these and do you think they will be any good?? Thanks for replies!
