No output through cards

Hi, I've recently moved case and redone my loop, and now my graphics cards don't give any signal through their outputs, but the onboard works.

Well, I checked the bios but I couldn't find anything related to the enabling/disabling of discrete/onboard graphics. Also, I haven't changed anything there since I changed my case, and it worked before (same hardware apart from case/loop)

Right, new problem. It's leaking.

Leak is fixed, loop is now bluer thanks to more dye
I got a display on the card for a moment, the post screen, then it went back to onboard. (Multiple monitors, one of them is running onboard until I sort this)

Nvidia control panel looks like this.
Getting output through the top card at the moment.
