I believe my previous system uses a z390 Asus motherboard (not sure as to the exact one). I borrowed parts from friends and swapped out the HDDs, added a sound card, tried a different mobo, tried a different PSU, tried different ram, did a bios reset, tried updating the bios, tried different OSes, all of which didn't seem to fix my weird stutter problem (audio would stutter, video would have weird stutters, the mouse would sometimes skip). I suspected it was the cpu as that was the only part I didn't touch
