First time installing Mackintosh. Need help

Specs for Reference:

ECS H61H2M17

4Gb G.Skill 1600mhz Ram running on 1333mhz

500gb 5400rpm HDD

Hey guys! i'm sorry if this has been posted before but i've got a few questions I can't really find or answer myself. I'm really new to this so sorry in advance.

First, I can only boot in safe mode. My first boot was in safe mode and my second boot was also in safe mode and something popped up saying a graphics card problem was detected but I don't recalling anything about installing a graphics card. I'm using integrated graphics.

Second, How do I boot normally without using safe mode? it always ends up in the black screen with he swirling thing. Am I just impatient or should I just wait for this?

Third, I don't have any sounds!! Is there any possible way to fix this? I'm using an HDMI cable because I intend to use this as an entertainment PC.

Anyways thanks guys hope you guys can help i'm literally lost. I downloaded this from Mackintosh.Zone.
