Question PC went blue screen during WiFi driver install

Sending my kid's desktop home with her, no ethernet at the house, so I got a TPLink WiFi card from Amazon, great reviews. Installed it in the little PCI slot under the GPU and it knocked the GPU out, no DVI output. Moved it to the little PCI slot under the CPU, and it was fine. Popped in the driver disc and started the install, and the system went blue screen, no message.

Now I'm back to no DVI output, even with the WiFi card removed. the Gigabyte MB has no video output, so I can't try onboard graphics to see what's wrong.

This is older stuff, Phenom 975, hasn't had any issues until this.

What's my next step, how do I get some video output so I can figure out what's gone wrong? I've proven the cable and monitor good by hooking up a different tower.

Swapped in a different GPU and now everything works fine. Seems coincidental that the other one died right then, not buying that story, but both of them are cheap and old, so I'm not going to put any more effort into it.
