Im building my wife a PC and now that my SLI is useless (for a few years now), I figured I'd give her my extra GPU.

I disabled the SLI in the control panel, powered down, popped the SLI and 2nd GPU out and gave my wifes pc the extra 1080. My PC started up fine, I booted up a game, and about 10 min in, the screen froze for about 10 seconds and then appeared to restart and now I have no video output. Did I brick my gpu? Any ideas on how to proceed?

I'm only panicking a lot.

Just to be safe do a clean install of the nvidia drivers. I've never personally ran SLI but who knows what might linger. Or if you really want to 110% it download DDU and the drivers. Reboot into safe mode (hold down shift when you click reboot, then pick the startup options), uninstall the driver, restart again (ideally with network disconnected) and install the nvidia drivers.

The only time DDU has fixed something a clean install didn't was when I was really messing with some settings, but it doesn't hurt to do it that way.

Posting this on all threads:

Fixed: this was my first ever build and after reseating my gpu, I saw some less than intelligent wiring (6+2 pin coming out of my card, daisy chained to a 6 pin that then went into the VGA port on my power supply). I cringed and pulled those wires and replaced it with a PCIE cable from my wife's new build (the reason I removed my 2nd 1080 in the first place). That cable only went into a CPU slot on the power supply but didn't think much of it. Turns out using cables that are not associated with your specific PSU is a nono. Everything works fine and I am dumb for several reasons but at least I learned with (seemingly) no catastrophic consequences.

Thank yall for your help and consideration and sorry I wasted your time.
