Just recently, I encountered my first error with my 360 unit. It kept freezing and then it just died. Three red lights around the power circle kept blinking. Luckily, my warranty was extended and I was able to get my 360 repaired free of cost. When/If you have to send in your 360 to Microsoft, be sure to constantly call them about it. It took me a week and a half just for them to send a box for my 360. I bought a NYKO Intercooler and havn’t experienced a problem with my 360 yet. I also noticed that it doesn’t overrev like it used to before i bought it. Just thought I’d throw this info. out for you guys!
