 * Place a supplement between the GPU Disipator and the keyboard metal, this will push the gpu to the systemboard, forcing a better contact. I placed about eight post-it's bended at the half. So far, so good. it works for me (eMaringolo). See it here: http://www.flickr.com/photos/emaringolo/373874916/

-Bad solder joint on graphics chip, which is in a ball grid array (BGA) package mounted to the system board. The problem is likely caused by an intermittent connection to the system board due to one or more bad or broken solder joints connecting the BGA to the system board. Thermal and/or mechanical movement breaks the connection, crashing the chip, yielding a blank screen or the BSOD.
