Hello guys, i've recently decided to get a rig so i can Overclock and have fun (this rig will only be used for that)

i think i've plug everthing but when i plug in a monitor into the mobo hdmi socket nothing happens.. i also had to gfigure a way to create a powerbutton, so i took a 12v one and i think it works.. right now my cpu fans and my power supply seems to work but as i said i cannot know much more.

This is the first time i work with a pc and its componnents, i normaly uses Laptop for daily use.

Mobo : Asrock z97 anniversary
CPU : Pentium G3258
RAM : 2x 4g from kingston
