Hi there. I just received my custom built OcUK machine and in it is the Asus GeForce RTX 2070 Super Dual EVO OC 8192MB GDDR6 graphics card. The other evening the display started showing green lines/artifacts across the screen and the writing on the screen was illegible. This was the same from the BIOS startup screen. I checked the cable and even outputted to another monitor using HDMI (rather than the DP cable) without resolution. In the end I removed the card, gave the connectors a quick clean and it finally (after a couple of attempts) started working again. Should I be worried about this or should I just put it down to a dirty/loose connection to the motherboard? I read elsewhere that green artifacts can be a sign of a failing card. Thanks in advance.
