Your CPU sits underneath that FAN and those metallic fins under the fan(heat sink/cooler). You would need to take a flathead screwdriver and remove the CPU cooler to see the CPU. I don't mean to be rude, but you are going to really struggle badly to cobble together a machine if you don't have the necessary knowledge to even readily identify the parts inside a machine let alone be able to determine which ones are dead.
Perhaps going and reading up on Hardware a little could help. start with some easy sites like tomshardware or sharkeyextreme as they regularly have some build guides for new machines/hardware so you can at least learn some of the basics.
PS: if I am not mistaken I think that is a very old ASRock motherboard (they used to be crap), at best it would be DDR2 memory in it, but I think it may even be only a DDR motherboard, regardless their is unlikely to be anything worth salvaging off it.
