Need help

So basically i just bought this pre-built pc but the audio ain't working i tried installing realtek drivers but it didn't seem to help, so what should i do?

Optimal placement for reduced hot air?

So this is a slightly outdated picture of my setup, but what do y’all think about moving where my tower is? Where it currently is, on top of my desk, on the right side, with the back exhaust going behind my monitors (to the left), I get hot sitting at my desk, which means the cooling is working for the pc, but not for me lol. My desk is a corner desk and has to be in this corner for space reasons, but I can move the tower around. I’m thinking the hot air gets trapped in that corner and stays around the desk, so I’m considering moving it to the left side to push to the left away from the desk. Any ideas? Under the desk? Specific direction? I know I’m going to do some trial and error but I don’t want to spend all day plugging and unplugging, then moving and repeat if I can avoid some of it. Just looking for some general insight for those experience in airflow systems of basement computer terminals lol. Thanks in advance. Cheers mates.

When I applied too much thermal paste

Only one piece left to upgrade from a I7-8700, to a 12700k i found at a discount store. Funnily enough i actually ordered this thing BEFORE i found that CPU. I knew it was overkill for my 8700, But I was prepping ahead, as I had plans to upgrade to a 12700k anyway. Just gotta get me a MB now.

How do I fix this it used to be around 99 to 1
