Oops, yeah that's what I meant in the edit. Autocorrect got to me. Also, turns out it wasn't working perfectly. Windows said the adapter had stopped working, so all I could do was run the desktop at 1080p again but actual games and stuff just wouldn't use the GPU. I'm confused.
Nothing loose, but I double checked and redid the connections just in case. Still nothing. I tried using my old graphics card and that worked just fine.
Also, booting time was a lot shorter when I used my old graphics card, which...is a thing. No idea.
So what I did was use my old graphics card, boot into safe mode, uninstall all drivers, got the new GPU in again. Got weird error messages, but got through to the desktop this time. Installed drivers. Restarting.
Now, waiting for the longest restart of all time to go through and I'll see how that turns out...
EDIT: Nope. Very, very long booting sequence but no errors. At the same time, GPU is not working. It's listed under Device Manager, but it has that error exclamation mark beside it. "Windows has stopped this device because it has reported problems (Code 43)" is what I'm getting.
Could it be a power draw issue? I wouldn't think so, but that seems to be one of the problems and would explain the inconsistency of the problem.
