God owning a 360 is real hard work! My 360 got the three red lights again so I opened it up to fix it up and the motherboard was so warped under the GPU and CPU the damn board musta been a couple of centimeters down I had to loosen the GPU and CPU heatsink screws to straighten it out. I guess the clamp fix is out of the question if I tighten the screws even a little the damn thing warps like all hell it looks like the board is going to snap under the CPU and GPU so I loosened it and it got the 2 red lights. Only problem is now I've "progressed" to the 2 red lights and my 2 red lights error is funny instead of waiting to heat up as soon as I switch on my 360 it flashes the middle green light then gets to the 2 red lights error within maybe 5 seconds. It isn't very dusty and the fan spins up to full speed(before coming to a halt as the 2 red light error kicks in) so I don't think it's a dust or fan problem. Like I said I had to loosen up the CPU and GPU heatsink so I didn't put the little Torx 9 screws that hold the motherboard to the bottom of the case on incase I warped the motherboard so it may be that but I'm also purchasing some thermal paste, I just wanted to know if anybody had any ideas I could throw at the equation. By the way is this thermal paste suitable: http://www.maplin.co.uk/module.aspx?moduleno=32417 Thanks.
Sounds to me your <S><O><L>. The board being so warped, thermal paste wont work. The only thing you might be able to do, is literally turn the 360 on without the fans for about an hour. That should make the board kinda flimsy, then just tighten down the chips and let cool. Also make sure you use Artic Silver for the paste. Once cooled. Try to play. IF that dont work sell that thing on ebay for like 40 bucks, and then buy a new 360.
