BSOD: system thread exception not handled a couple hours after taking out and putting back in graphics card

[Maz8]

I took out my gtx 970 because I needed to test if this other graphics card I have worked or not. I didn't install drivers for it or anything. After I tested the other card, I put my 970 back in my pc and played games for a while. It just randomly crashed and gave "system thread exception not handled". I never get BSOD's. Is it possible I may have damaged the card when I took it out?

Damage would be noticeable if so, only thing i can think of if you were careful with the card itself is maybe the little gold pads at the bottom that you push into the PCIe slot, check them for damage / dirt / discolor, if all pads intact try some pure alcohol and wipe them down, let dry and try a different PCIe slot, would be a good idea to reset ya CMOS at this time to, let me know !

Why are you so surprised.

If you removed the card to test another video card in the system and it was not of the same Gpu make or model number of graphics card.

Even if another Nvida based Gpu with a different model number.

You should of removed the Nvidia driver for the 970 based card before you fitted the other graphics card to test it.

Once you connected the other graphics card, you would of then had to install the video card driver or windows would of set one up to run with that video card if a different model of Nvidia card or one using a Amd, Ati gpu.

When you finished testing the card you should of also removed the video card drive that was installed by windows or you installed manually by the driver set up and install program.

You then should of put your GTX 970 card back in the Pci-e slot of your motherboard.
And again re installed the correct video driver again for the GTX 970 card.

If you fail to do this and also still left the prior video card driver installed of the card you were testing it is why you got the System thread exception error message.

Even if you don`t install a driver it`s self if using windows 10 for example windows will auto install a video card driver for the other model or brand, different Gpu used with the other graphics card placed in the Pci-e card slot when you boot into windows desktop mode as part of auto driver selection or set up.

You must still remove the video card drive in such a case.

I am willing to bet this is what you did not do when swapping the video cards over removing the current video driver set up in windows.


As an example if you have a Nvidia based Gpu card.
And then place a AMD, ATI based Gpu card in the system without removing the old video driver before swapping the cards it always leads to an error or a problem with the card running right in windows.

And even if the video card uses the same brand name of a GPU but is a different model number or range of card. example a GTX 970 and a GTX 670.


Download this from the link bellow, install it on your system and run it.

Remove all Nvidia drivers, and any AMD, Ati based drivers also.

Restart the machine.

Go to the Nvidia support web page and driver downloads page, get the latest Nvidia driver for your model number of Video card Maz8.

Restart the system after the install.

And everything will be back to normal without the System thread exception error message happening.
