I had 2x1GB installed on my laptop i then recently received 2x2GB of ram from newegg. First of all when i installed both of them i could immediately tell one of the sticks were bad because my laptop would load up then get a blank crazy looking picture. So im sending it back for a different one. So now at this point i installed the one good working 2GB with my old 1GB which gives me 3GB. Keep in mind i stayed with the same brand, model, etc. Anyways so with 3GB installed i go to view system specs and it showing that i only have 2.25GB installed why is that? Is something wrong? I know my laptop can hold up to 4GB so i dont know what the problem is. Any help will be greatly appreciated.
