WOTLK Client crashing

I recently got a new PC and for some reason I cannot run wotlk warmane. at random times (within 1-20mins) my game black screens and forces me to turn off pc. I can hear in game noises but i cant do anything. I can run wow retail and other games such as counterstrike perfectly with no issue at all but for some reason I black screen when trying to play wotlk private server.

my computer specs are
Processor AMD Ryzen 5 1400 Processor
Operating System Windows 10 Home 64-bit English
Memory 8GB DDR4 2400MHz (8GBx1)
Graphics P1: AMD RX 570 4GB DDR5
Storage 1TB (64MB Cache) 7200 RPM SATA
Media Card Reader Media Card Reader, USB 3.0, 2.0, Type-C
Wireless Connectivity 802.11ac (2x2) + Bluetooth 4.1

im not very computer savvy but i'm aware of basic knowledge and i can't seem to understand why this is happening, my last pc was win7 and a gtx 750ti and ran decently and no problems like this.
