I am running 64-bit Windows 8 with a 64-bit processor on a Dell Inspiron N5050. I just upgraded the ram from 3 GB to 7 GB by adding a 4 GB card. I looked online and this computer can support up to 8 GB of RAM. I looked up the system's specs under properties and it says I have 4 GB. Why is only 1 GB of my new RAM showing?

Sorry. I should have asked for specs. The principles of what I said still apply. you should be installing 2 x4GB. Try running just the 4GB where you were running the 3GB. By itself. See what your system shows.If that works leave the 4GB in the first slot and add the 3GB in the second and see what you get,

You have a dell. It is a proprietary board made to their standards, not to the standards used by other motherboard makers.
So not all memory will work correctly when Installed in a Dell Mobo. I know this from having and working on dell products.
This means you need to hunt for memory that is guaranteed to work in your mobo. You cannot expect just any ram to work.
If your board has 4 slots an will max out at 8GB likely you can put in 4x2GB.this would be two Matched sets or kits.
Your mobo may very well not be designed to accept a 4GB module. You cannot mix and match memory and expect it to work. Some people get lucky. So you should endeavor to place 4 x 2GB of 2 matched sets if not four of the same 2GB modules. In your board if it is like most dells with 4 slots to get the use of dual channel modules you can load 1x1GB,
2x2GB, 2X4GB. If not your memory will only run as single channel. If it runs correctly.
