I have an xbox360 slim. Last year I had to replace the original power brick; the fan stopped working, and it overheated in about 30 mins. Instead of cleaning the dust out of it, I went online and bought another one with the serial: X803215-002. I think is an after market ac adapter. I was playing Boarderlands 2 a couple nights ago and it just randomly turned off. I tapped to power on button on the xbox it and the fan on the brick turned on for a half a second, and they died again. The light on the brick blinks on and off. When I unplug the brick from the xbox, the thing blinks a couple of times and then stays lit in standby mode. Now neither the fan nor the xbox will turn on. I think its a clogged fan again. any suggestions?
