I have a Packard bell Easynote LJ65-AU-055UK i hvae tryed to upgrade the memory in the laptop from 4gig to 8gig. wich i have been told by packard bell that is the max ammout of memory that the board will handle but when i put the memory in it will show in the bios 8gig but when it come to boot the windows logo shows then stalls after further investergation with packard bell the said i should send the laptop to them at a charge of £55 just for them to have a look. The memory i baught is corsair ddr3 memory the funny thing is if i take out one module it boots fine i have even swoped them round so i know there isnt a problem with the ram. is there anything else im missing??
