Dear geekz,
Bro in law has a dell 640m which had a ram upgrade and vista installed about 2 months ago.
Core Duo 1.8/ 1g+ .5g ram/60G HD
Last few days it's had BSOD - something about memory ... and so i swapped old ram back to make it .5g + .5g and now it will not boot. the bios LED flashing codes it to be "no SODIMM" - the thing is, putting all sorts of "working ram" from other laptops does not make it work.
diagnosis? motherboard gone?
