[quote name='rly723']bad news lol
it happened again...red circle and screen wont load, just get a clicking sound and the screen to contact cust support. after a couple hours it got back to working with no problem, but i have no idea whats wrong with it and expect it to happen again. i dl'd some roster update for nba2k6 and mvp 2005 and transferred them from an action replay memory card to the xbox hard disk. could their be a corrupt file that could be causing this or a hardware problem?[/QUOTE]
OK, so it worked again after a few hours of just sitting there, right?
Sounds to me like the fan on the video card is dying, causing your unit to overheat and lock up.
Wish I had a work-around for you, but I'm not a modder and wouldn't begin to know how to remedy this.
Do a search for a new internal fan for the Xbox and maybe you'll be able to pull something up?
