My weird random video problem came back. And then last night, my video just altogether died.
Before I RMA’d the video card, I thought I’d try a couple things. I swapped out a power cable attached to the video card, and voila! Video!
…but now Windows 10 is stuck in a reboot loop, where it tries to boot automatic repair, but then just makes it to a screen that says “Your PC ran into a problem and needs to restart.”
This is kind of infuriating.
I put back the old cable, and now I have video, and I’ve booted normally. Then I swapped back to the new cable, and it’s also working normally again. Before, it was broken even after hard power offs and switching off the power supply.
The fuck is even happening with this PC?
Welp, back to onboard video. Onboard video driving an ROG Swift.
