Bad Playback and Performance

Hello, I need help with my use of Premiere Pro. I just got a new PC and I was sure that this would be just as good if not better than my laptop. But the playback speed and performance of my laptop were still better, even on an older version of the software. Only, on this system, the playback takes almost a half minute to register its spot from when I moved across the timeline. There are even times when I open or switch to a different window and the playback does the same thing there. I'm not sure if it's my specs or anything because I have looked at all the methods and alterations (Switch to Mercury Playback Engine Acceleration GPU (CUDA), bring resolution to 1/4, Default Input to None, Clearing Media Cache, and reserve majority of RAM to Premiere) to increase performance on Premiere Pro specifically but I have found no change in activity. 

My Specs:

Processor AMD Ryzen 7 5700 3.70 GHz
Installed RAM 16.0 GB (15.9 GB usable)
System type 64-bit operating system, x64-based processor
