Hey guys i have opend the case of the rx570 and then the cooler i habe changed the thermal paste but i realized that someone else put not thermal paste on it ,it was something silver-based. I clean the most of it and then have i put normal thermal paste on it. I installed the cooler back and turned the pc on, but there is a black screen. Can someone help me. I looked for some defect on the plate of the gpu but i dont found really something.
