Aorus 15p XD problem with nvidia rtx 3070

I’m sorry if it’s not clear, I’m using Google Translate. I bought the aorus 15pxd a long time ago, I remember that after a day it started crashing in games. Bsods appeared with errors such as “clock wathdog timeout” or “machine web exception”. After analyzing the performance of the graphics card with msi afterburner, I concluded that the graphics card was either damaged at the factory or was performing thermal throttling but poorly. While playing, fps drops occur and the monitoring shows that the voltage decreases to 70-80 from 120 and the frequency increases to 1800-1900 from 1560, I really don’t know what could happen and I don’t want to think that I have to replace the entire board.
