So I've had laser issues for nearly a year now, but they were normally held off by cleaning the laser every few months. However, last time I cleaned the laser it still refused to work. My dad then cleaned it later that day, still no joy.

Basically, it wont acknowledge that disks are in the tray. If a game wouldn't actually work, it would say the disk was unreadable during the game. However, I have to keep opening and closing the tray 100+ times to get games to work. And when they do, there's at least a 70% chance it says "Disk unreadable" before the game actually fires up.

The strange thing is, however, that Halo 4 and Skyrim will work about 70% of the time, rarely saying "Open tray" or "Unreadable", but the rest of my games wont read.

Skyrim I've had for nearly two years, so there's a touch of wear-and-tear on the disk, but no more than my other games. And Halo 4 is in fine condition.

But the games that wouldn't play I took to a friends house to try them out, and they all worked fine (except for Dragon Age: Origins which actually does have a big scratch).

So, a new laser will apparently cost ￡35. But what I don't get is why does my XBOX seem to pick favourites with Skyrim and Halo? Lucky for me they're my two favourite games but still, it's strange.

And ideas?

Are your other discs dirty? How have you cleaned the laser? One of those cleaning disks or compressed air? Try both if you have not yet.
