@joroje: After pila ka days, I decided to play with my Xbox360. I was testing out Enemy Territory Quake Wars for about 10 mins when I noticed some 'black snow' in the background when the game is in training or campaign mode, so I decided to test another game. I turned it off first w/o turning off the power supply so that blower beneath the X360 would still be on (as per your instruction). When I turned the main unit on, I got the (1RL - Error code E74).
Need you to fix my X360 again.
Update: I googled for "e74 xbox360 error fix" and one of the results matched my situation...

apparently this problem happened to me also. I knew something was wrong when the screen during GTA turned all blockish. But i thought it was probably this disk because in the dashboard everything was fine along with Halo and COD. So i reset the xbox and i got the message. I talked to xbox support and they said my warranty will cover it (i bought the elite on 1/16/08 just a month after MS changed its warranty length) If you bought an xbox from any time after december of 2008, you should be covered for the next year or so.
