Xbox 360 freezes during start up... can't clear the cache
My son's Xbox 360 slim (core unit) all of a sudden started having a problem. Whenever we turn the machine on, it goes through it's normal swoosh routine, and then after that it gets to the screen where it's about to load the dashboard, and it just basically stays on that screen and you can't do anything.
I've been googling today trying to find out what to do, and a lot of the suggestions I get are to clear the cache. However, I can't get to the part where I can select system settings and clear cache, because it doesn't actually get to the point where the dashboard will load. It's before the dashboard has loaded.
Is there any way to clear the cache before the dashboard actually loads ?
Or any other suggestions ? ( it's out of warranty, and spending any $$$ to fix this is probably a bad idea. I'd probably just buy another 360 from Craigslist or something if it came down to it..)
