Hello @ImA1M sorry you are having an issue with your system. Does the computer instantly turn off when you put the old GPU? If it does instantly turn off with the old graphic card, we'll get to the 3080 in a second; put the old card back in. Take out all of your RAM sticks and put 1 RAM stick in the first RAM slot closest to the cpu socket. Then unplug the power cord from the tower and hold in the power button for 30 seconds. Then plug the power cord back in and boot up your system. Let then see if it boots without instantly turning off. Let us know the results.
