I'm trying to upgrade my laptop's hard drive and ram. Is there place i can look to see what's compatible with my laptop? I would appreciate it if someone could point me in the right direction. I currently have 6gb or ddr3 ram installed and i wat to upgrade to 8gb and also possible upgrade my hard drive from 640gb to 1 tb. I'm looking at a few parts online but i would like to know if they'll be compatible with my laptop.
