Weird lag and audio reconnect

My PC has started to make a 2-7 second lag where it disconnects-reconnects my headphones. It happens after 45-60 min in idle or when gaming. It makes the sound as it does when it reads from a harddisk.

Specs: Asus B250-prime-m I7-7700 Geforce 1070 Recently upgraded from 16-32GB ram, the lag started before upgrade. Samsung SSD 250GB WD 1TB HDD Kingston NVMe 250GB and 1TB (1TB upgraded after lag started)

I've run diagnostics on CPU - no issues found Crystal disk on Harddrives all said 100% (HDD only said good, no percentage) SSD Life Pro which said my SSD (boot) is 100% fine and will live to 2029.

My last idea is it could be an error from my HDD which makes no sense since everything relevant is on my Samsung SSD.

In log event the closest I've gotten to finding error is a microsoft windows security auditing.

Any help is greatly appreciated.
