Well, since I'm new to here, I will post this here. It's hardware question after all...
Anyway, get to the point. I have one XBOX 360 Falcon unit. It just got struck by 3ROD, and i was panicked. I left it for a couple of hours and tried turning it on, then it worked. However, when i turned it off with a CD inside, and turned it on again, 3ROD happened again. I took the CD out and left it for a few hours again, it worked out. This happened about 2 times. So, should i just get it fixed or is there other solution to get it fixed without using money? (BTW, warranty is off)

thanks dwks. I wonder if they sell as5 silver thermal paste in malaysia though

To everyone- Take out the X-clamps (you can burn it and fry it after that- X-clamp is the main reason WHY your XBOX 360 get 3ROD) and reapply the thermal paste on both CPU and 2 GPU chips. After that, take the fan out, turn it on and let it overheat- same as tower trick, but even faster as there is no fan or heat pipe. (Don't put heatpipe either) It will resolder the connection with GPU chip, and after around 20 minutes, turn it off and cool it. Turn it on again after that, then you will be back to your XBOX 360 in no time.

Don't Ever Try TOWER TRICK. It's gonna fry the whole XBOX and you can't fix it afterwards if you do it a lot of times. Just send them to a game shop in this forum, they can fix it for 100 bucks, or you can fix it yourself.
