Everything was working fine until I pulled the card out of my PC as a test then reinstalled it, even though I was careful. It never worked again...

Symptom: got a display in BIOS, I see the Win10 logo loading up, then I loose display. USB keyboard and mouse seem to turn off, must hard reset the PC.
If I unplug PCIE connector from card, plug monitor in IGP, everything is fine.
If I plug back PCIE connector to card, even still with monitor in IGP, same symptom, no display/crash after win10 logo.

I tried:
different PCIE connector-> same thing
different PCIE slot -> same thing
boot to safe mode, run DDU to uninstall drivers, reboot, if card is connected, symptom is still present, if I unplug it I cannot install the driver because the card is not detected.
swapped the card to an older Win7 PC -> can get to Windows fine, but drivers fail to install (error code 28). I tried latest version and an older one, same thing.

You may want to work with a system that has some fairly new hardware. I'm kind of skeptical that your PSU might be the issue or that the card has died given that drivers don't want to work with it but then again when you mention Windows 7, I'm assuming that test system has an older PSU as well. What's the make and model of your PSU and how old is it?

Are you sure you're on the latest BIOS update for your motherboard?

Hey man, thanks for helping!
My PSU is a Corsair HX650W. It is getting pretty old (7 years, just came out of warranty a month ago), but never had a problem with it... unless it killed my GPU!
My MOBO is kinda old but I do have the latest BIOS available from ASUS.

Edit: yeah the older Win7 PC that I tested the card on, has an older Antec Earthwatts 430W PSU.

For what it's worth, I just tested the PSU with a little PSU tester thingy. Everything looks OK, except that -5V light, but from what I googled, it seems to be an older thing that is not in recent PSUs?

Is there an option in the motherboard that lets you choose default display? also, try clearing cmos if switching main display from igp to pcie doesn't work.

Hey guys, I don't get why but it seems OK for now.
I figured I would stop wasting time with this old gpu so I snagged a used GTX960. I figured, if problem is solved, nevermind what happened with the old 550 and if not then I'll look deeper.
I installed the 960 and same issue.

1) I looked in BIOS and there is an option to choose default display, default value is AUTO. I set that to PCIE. Same issue.
2) I reset the BIOS settings to default. Same issue.
3) I booted to safe mode which worked fine, and saw the card detected as a generic card. I installed the NVIDIA drivers, then it seemed to be recognized OK as a GTX960. Reboot = same issue when Win10 starts loading.
4) I was about to give up for now, but just hard shut down PC and rebooted again normally, bang it got to Windows and all is fine. I've rebooted several times and updated driver and it is still OK for now.

I HATE when that happens and you don't have an explanation.
Software/driver issue? PSU/mobo starting to act?
