Glitches and poor performance

Hi guys,
Since booting up new pc I have problems with resolve, both on 19 and 20
I have either stuttering playback (the resolve doesn't says that i'm losing frames) or black and green glitches as seen in screenshot.
I tried many many thing and still nothing.
specs:
DR 20
intel core ultra 7 265KF
64GB RAM DDR5
RTX 5070- tried working on both types, studio and game ready, currently studio 576.52
MB Gigabyte B860M EAGLE
Win 11
SSD m2 Samsung and additional Lexar SATA SSD both have enough space.
