Ok so heres the problem.....
I got GTAIV eager to play it and i put it in, started it up and then started playing it and it was fine, Then after a few hours it crashed. I thought "ok i heard this can happen it's alright" so i restarted the Xbox and started playing it again and the crashing became more frequent and more often to the point i had to get it replaced. Once i did i thought it would be fine now but soon enough it was playing up again crashing all the time and i can't work it out, My Xbox is less than a half a year old and in perfect condition and the disc hasn't got a scratch in sight so what's wrong?
All your ideas are welcome!
Jam it back in, in the dark.
