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.

    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.

      I would still call this a personal success because how much you learned from this about cable management. I trust that from now on you will never take whatever random cables and p’ug them into whichever connection that looks. I hope also understand that it’s not always possible to diagnose a system issue without personally looking at it and trying to use it to see what is going on. For me, I would never think of asking the person if their video crd is daisychained but because is something normally never done. Each GPU gets their own cables plugged directly to the power supply

        I vaguely remember ~7 years ago when I built it having issues with the gpus. The main issue was that I needed to boot my OS with a single card, get everything up and running, then shut down again and add the SLI and 2nd card. I also vaguely remember thinking the wiring was silly but it worked and for 7 years it was “if it ain’t broke don’t fix it” until now.

        Update on my building journey: my wife’s new build (waiting for 3 more case fans):

          That’s a good build for her, a very nice setup.

          Now you know that SLI doesn’t mean anything anymore. It’s always better to buy a single higher GPU than 2 lower ones. And given how high the prices go, there’s no limit on how much a person can soend on one.

          I will recommend that if you buy a 5060 or 5070 in 6 months, your wife will immediately see a big boost in performance in anything and everything she does on computer.

          So you know, for gaming, the 4060 beats the 1080 Ti. The 4060 does AV1 video encoding, I don’t think even the 3090 has that. Definitely not the 2080 Ti. So ifyou buy a 5060 or 5070 to put in her system, everything will run flawless. I don’t know if that 1080 is actually restricting ir limiting her CPU performance. That’s another reason to upgrade an 8 year old GPU, it will allow the CPU run constantly run at full speed.

            Yeah my sli was useless about 4 years ago when games stopped supporting it. That’s why I’m giving her my 2nd card because it’s useless in my rig.

            As for a new build for me, I should probably just wholesale and upgrade to a DDR5/current chip mobo because I think my i7 6700 is really what’s holding me back past my card.
