Hi, I'm not very computer savvy very much any more.
I bought a GeForce GTX780 on eBay (and maybe that's that issue) or maybe it's that the card is incompatible with my desktop. I'm just not sure how to tell.
 
when I put the card in, the fan turns on, but the monitor doesn't get a signal via the HDMI port. I have a brand new ASUS 28" 4k monitor.
My tower is a little older, but can someone help me find out if the "specs" are incompatible and I should return it?
 
Thanks,
Dan
 
I bought the PC from MicroCenter 6/30/2020. I've upgraded to 32GB of RAM

An AMD Ryzen 3 2200G has it's own Radeon Vega Graphics..The BIOS might be set to exclusively use that and not the GTX 780..Clearing the CMOS should return it to automatically using a graphics card if one is detected in the PCIe x16 slot..Clear CMOS (usually with a jumper somewhere) according to the motherboard manual, or unplug your PC and remove the motherboard CMOS battery for 5 minutes.

Worth a shot.
 
Otherwise, try another card in it if you have, or try the GTX 780 in another PC as suggested above..You could take it to a PC shop for testing, shouldn't cost much or take long.

I have a GeForce GT1030 2GB in there now and it works fine. I wanted to go to 4GB. I do a lot of Lightroom and Photoshop work and wanted a little more power.
Maybe this card is a dud.

Are you using the newest Nvidia drivers? They discontinued Kepler support, 7xx series and below. https://www.techpowerup.com/287749/nvidia-releases-game-ready-496-13-whql-geforce-graphics-driver-support-removed-for-windows-8-1-8-7-kepler
