GPU not connecting to PC

Snowiehawk · November 9, 2019

Hey guys, my Graphics card stopped connecting to my pc all of the sudden. I was working on my Mac for a few minutes while my pc idled on a game, I disconnected my main Monitor from my PC to plug it into my Mac. Everything was fine for about 10 minutes, then my other two monitors went black even though my PC had not went to sleep. All the sudden I hear my GPU fan spin up to what I assume was max. I shut my pc off through brown out because I couldn’t access any of the user interface, but a strange thing happened, one o my fans remained on even after I turned the pc off and unplugged it. I have not been able to get my graphics card to connect to my pc since. My GPU is an Nvidia 1060. The fan spins up when I turn on my pc but it doesnt show up in my device manager any more... if anyone could help me figure out what’s going on, I would really appreciate it.

This seems a bit fractured. Let me see if I get the progression right.

1: you hardline swap a monitor off a multi monitor rig.

2: while you are doing this there is a brown out that you noticed because your main rig went wonky. As fast as you could you shut down your main rig but it appeared to not completely shut down. Specifically a single gpu fan (but not all of them) spun until you pulled the wall power even though the machine was powered down.

3: you repower your rig after the power weirdness, but while the rig itself works it no longer recognizes the card in the device manager even though it is sending power to the GPU fans.

Is this correct?

Kind of.
1. I unplugged the monitor to use it on a different system. The system reacted normally, changing my other two monitors to the primary monitors. This was fine for about 10 minutes.

2.Then, without doing anything to my pc, the two monitors that remained connected to the pc went black. After attempting the normal troubleshooting of pressing spacebar, power cycling my monitors, and replugging in the old monitor (to no avail)

3. I held the power button on the pc to shut it down. I started it back up but the monitors remained black.

4. I connected one monitor to my onboard intel hdmi port to see if my gpu was connected in device manager, but I found it was not

since then I have not been able to get my gpu to connect to my pc. The fan on the gpu still spins up when I turn on the system but it doesn’t connect to pc.

i would try another PCIE slot but I only have 1 16 pin on my motherboard (b250m bazooka)

GPU: Nvidia GeForce GTX 1060

CPU: intel Core i5

MB: B250M Bazooka

PSU: thermaltake smart 600W

sorry if my first post was confusing. I appreciate anyone willing to help

I'm by no means an expert but I had a 1050ti do something similar. My system shut down unexpectedly but still had power to the board even though all fans had stopped. When I finally got her back up an running the monitor was completely black although it was receiving a signal and even though the PC would boot I got nothing but a black screen from the GPU. I replaced the GPU with a radeon 580 and although I could get to windows the PC was still giving me a fit when I tried to run a game. Turns out it was a bad PSU and not the GPU all along. I put the 1050ti back in it and it had no issues. Wasted 200 bucks on a card I didn't need when all I needed was a PSU. I was also using a Thermaltake PSU. Not going to make that mistake again.
