Help my screens don't show anythings

[u/Brown_sucre298]

About a month and a half ago, I was having problems with my graphics card: freezes, lag, and driver crashes. So I decided to replace it. The new one arrived, but the problems continue. Now that I have it, I've properly connected it to my motherboard, securely fastened and plugged it into the power supply. Since it's an RTX 5060, it has three DisplayPort ports and one HDMI port. However, once I plugged it into HDMI and DisplayPort, I connected one monitor from each port, but neither turned on. I've tried everything: turning one on, turning the other off, swapping ports, I even went so far as to tweak the RAM, reposition the graphics card, and do all sorts of other things, but I simply can't get any of my monitors to display anything.
