Wanting to upgrade PC for ~$1800.

Hello, my current build is a partial upgrade from my previous (and first) build. I'm fairly certain the power supply is dying (it's ~13 years old) as my PC has been blue screening frequently the past few months.

Would someone be able to recommend a new build primarily for gaming but also capable of audio engineering work? Here's a similar build to one I found on YouTube, I'd love suggestions!
