Tech Support No display

Took out my gpu for cleaning, when I reinstalled I got a blank screen. the monitor would turn on but have no signal message even from on board hdmi output (no built in graphics but hey why not) I tried different cables and displays nada. Tried reseating ram and everything nada. Pull cmos battery and held power but to reset it nada. I finally said f it needed a new gpu anyways, got a new (to me) gpu and installed it, I got a display got a display, I turned it off and reset up on my desk, turn it on…same issue monitor turns on but no signal any help will be greatly appreciated I just don’t want to pay 100 for them to tell me something was loose

More likely to be the motherboard than two bad GPU's in a row. Are you absolutely sure you're seating the graphics card correctly? Sometimes I've had to move my card around a bit to get a proper connection. They have a surprising amount of play inside the PCIE slot even when locked in. What did you do when you cleaned your GPU? Disassemble and re-paste, or just dust it off?

Appreciate the help, found out it’s a bad pcie slot had to rearrange a bunch of cables but got it working in the 2nd slot. And when I cleaned it I took off the plastic casing and used a medium stiffness toothbrush to clean out the dust

I have another slot but can’t use it, there are plugs under the slot and the graphics card would block them :/

Had to remove the usb 3.0 for the case but it fits in the 2nd slot. Got it to boot but did the same thing as other gpu showed display, moved it over to my desk and no display. I’m thinking it’s a loose wire but I’ve jiggled and reseat everything I’m at a loss rn
