Elder Scrolls V Special Edition freezing; game audio still plays

[joeunderscoremorris]

I recently bought the RTX 2080 Gigabyte Gaming OC and when I play Skyrim on higher settings (anywhere from 4k medium to 4k ultra) the game will load up, and after a few seconds or so of playing and walking around it will freeze up unexpectedly and the game audio will still play. My PC riuns the game fine, with 4k ultra settings at 60+ fps before the freeze. But if I take the settings lower, like at 4k low or 1440p high, it runs just fine w/ no freezing. When it freezes, it sometimes will let me alt tab to the desktop to shut Skyrim down via task manager, and sometimes will not, so I have to restart the whole computer. I don't have any mods enabled whatsoever and my os is Windows 10 Pro.

System (to best of my knowledge, at school rn)
Corsair TX750M Gold 750W
Ryzen 5 1400 (yeah ik it's bottleneck; looking for an upgrade)
Crosshair VI Hero WiFi AC motherboard
1x 850 Pro 256gb Samsung ssd
5x 240gb Intel ssd (not sure what specific model)
Gigabyte RTX 2080 GAMING OC 8GB
16gb DDR4 Ballistix Sport
4k 60hz Samsung monitor
Arctic Freezer eSports Edition Dual Fan Cooler in Push Pull
Fractal Design Meshify C (2 corsair airflow and 1 thermaltake static pressure fans in front and 1 corsair airflow in back)

My PC has really great airflow, with 2 fans for the CPU cooler and 3 for the graphics card, plus the case fans, so I wouldn't think heat throttling is a problem. Both my cpu and gpu cooler fans don't ramp up while it runs, so it's probably <60 C, although I never checked.
