Computer freezing every so often, brand new just built a couple days ago

[Aitchy]

Hey there I am having some trouble with my computer and I was hoping someone could find out what's wrong or a solution to fix this. Basically my computer is freezing every now and then and I can't seem to figure out how. It's mostly (not always) when I am using chrome. Everything will stop working and it takes about 30 seconds for it to fix and it will go back to normal. It never happens when I am playing games and my fps seems fine. But something tells me its my RAM. I bought Kingston Fury 8GB but I accidently bought it in the 1 stick module and not 2x4 GB. I know silly me. anyway I was hoping someone could help. Could it be that my computer does not have use of dual channel and only single? I am getting another stick when I have the money as dual channel is always quicker.
