No worries guys i fixed it anyways.
Even though i didnt get a reply
ill post my solution, incase anyone ends up in the same position as me.
This Pc was my first build so when i made it i didnt completely read all the instructions.
Yesterday i completely disassembled my rig and noticed i hadn't even put the riser screws in to elevate the motherboard from the backplate.
Im guessing when I changed the ram into different slots it pushed the MB back slightly and the back of the MB must've been touching the back plate where it shouldn't have been.
Another thing i noticed was that i had my PSU fan facing upwards, towards the inside of my computer when i should've had it facing downwards.
For new PC builders it is quite easy to make this mistake because naturally you'd want the stickers to face upwards so you could read them.
The reason you'd want it to face downwards is because it is usually an induction fan meaning it brings air into it instead of exhaling it.
Keep in mind though, that if your case doesnt have any holes in the bottom for your PSU fan you'd want it to face upwards as it needs to actually be able to breathe.
Even making sure your cable management is as tidy as it can be could help a s***load.
At least i've learned my lesson and im lucky it didnt do any damage where it could've.
Cheers for the great motherboard, mouse and GPU anyway Gigabyte, keep up the good work!
