i have been playing gta4 since i got it about once every three days, and the time periods were from 30mins - 6 hours and today when i went to play a multiplayer game where u and your team have to smuggle drugs or something and it just crashed.
so i turned it off and then turned it on and it was on the loading screen and crashed again!.

so i left it for about 5 mins and tried again and it actually loaded my profile and then it crashed again.

what i can see by the screen is that it has a fuzzy image and blurred out, and it just makes a screeching sound when it has crashed.

if it happens again i will take a picture this time.

at the moment i have left the xbox 360 core edition console and all its bits next to a fan, and im gonna leave it there for 30 mins.

i bought it from Game and it was pre-owned.
