As far as I can see for a first build budget PC components are compatible, though a little more information on your RAM choice would be helpful.
Is you look on this page, click here you will see in the left hand corner, CPU support list and memory QVL, these are lists that the motherboard has been tested using the listed CPU and RAM, your CPU is listed but I am not sure of your ram choice as you haven't given enough info.
RAM compatibility can be a problem, my latest build has given me a lot of problems but I also had a faulty mobo, which made things more difficult.
So check your RAM. If it is not listed that does not mean it isn't compatible with your board, but it is worth thinking about.
I am having a look at the graphics aspect and will post back later.
