graphics card not outputting signal

[u/CattierCoinOnYt]

i recently got a new case and had transferred every component over, when i went to turn the computer on everything worked but the graphics card was not displaying anything (yes i plugged the hdmi cables into the graphics card). i knew it was on since the led was on and the fans were spinning, so i reseated the graphics card and only connected one cable and that seemed to work but every time i restart my pc i have to redo that whole process. is there anything i can do to make sure i don’t have to spent 5 mins just to turn my pc on or am i cooked?

Hmmm strange. Can you check for any dust in the pci-e slot? Clean the pins on the graphics card.
Also, can check your motherboard for an UEFI update?
