    Download memtest86 and try to boot from it and run the test overnight. If you get any red bars on the screen you've got a bad stick of RAM.

    Otherwise, make sure the speed and size of the RAM stick is compatible with that particular laptop. You've pretty much narrowed down that RAM stick as the culprit based on what you've posted, there is a very slim chance that anything else is at fault.

    Have you tried swapping the memory sticks between the slots? It's mostly the memory being incompatible or damaged.
