I'll take it PM me.

There is this stuff called goo be-gone, I think you can buy it at home depot or lowe's. Use it to remove anything sticky, works like a charm.

You could alway get a flash drive as a back up if you don't think you will need a hard drive. Getting a 2 gig flash drive would alot cheap than a hard drive, as long as you don't download alot of stuff you should be ok but im no expert.

Don't draw too early. When you are in a duel wait till the opponent pulls his gun because if you mark your targets too early he will dodge and kill you so wait until you see him pull his gun a little then mark. Go for his gun or his head it should only take one bullet.

Check the AV cables maybe they're not set up right.

Have you sent your xbox in for repairs recently? You might have lost the license try redownloading them.
