Just wanted to post this in the thread in case someone has the same issue as I did:
After doing some research and scans, I found out that any Razer application, especially Razer Cortex and Synapze, was causing the DPC Watchdog error. If you're using any Razer applications with a NVidia audio driver, remove the Razer application from the computer. It seems as though Razer produced these drivers without realizing their code isn't compatible with NVidia's. Since removing these Razer applications about a week ago, my computer hasn't had a single BSOD or any other issue as well.
Feel free to message or comment below!
