Computer not detecting all my RAM [Anwsered]

Computer not detecting all my RAM

Please forgive me, I don't know much about computers so I won't understand any terms that are too technical, or instructions to do something without details as to how to go about it.
So please don't be annoyed if I ask you to clarify.

I'm pretty sure that my computer (ir's new, I just bought it and everything was factory installed) isn't detecting all of my RAM.
I paid for 8GB but in the middle of a lot of installations (my latest frustration is with the WoW installer) it'll just stop short.
I ran a memtest and didn't come up with any errors.
What's going on? All my installations are slow or don't install at all.
Every so often I get the memory_management BSoD, but unfortunately it's rare enough that I don't have the whole thing for you.
I've
also gotten the IRQL_NOT_GREATER_OR_EQUAL  one a couple times.
I'm really at my wits end and don't know what to do - I paid thousands of dollars for a gaming computer that does not work, apparently.
Anyone have any ideas?
