I had 4 gb of ram initially, and then I had purchased a 8gb ram stick. Once I installed that, I was still only able to use 3gb of the ram

I'm not exactly sure what to do, so please help

What happens when you remove the 4gb module and only have the 8GB module installed? If it doesn't work.. then it sounds like you might have bought bad ram. Do both of them have the same timings... did you remember to doublecheck from your BIOS?
