I have been trying to upgrade my Gateway M675 from 512MB to 2GB. The problem is when I do that my hard drive won't even turn after the initial screen. I am trying to use PNY 1GB DDR SODIMM N .
Yes. I have tried one at a time in each slot. I've tried using one new 1GB along with my old 512MB. It is the recommended memory. I had looked it up and had Best Buy verify before purchase.
