hai,
so recently I bought a pc hoping to put a cheap GPU (gtx 660 oem) in it and it working... but that wasn't so easy. I have tried everything! but it won't show up in device manager nor will Nvidia drivers recognise there is a card and it says it doesn't support this version of windows even though it's supposed to support win10!
I am not sure if the pcie slot is broken or if windows 10 doesn't support my card. or if my card is just entirely broken.
I have updated all windows drivers, I've tried to reinstall windows, I cleaned all my ports. I am booting in legacy because I read somewhere that the gtx 660 doesn't support uefi natively...
I also turned on secure boot (uefi) just to see what would happen.. I started up dell diagnostics and it gave me error code 2000-0332, I have no clue what this means other then something with the graphics card, this made me to believe the slot wasn't broken nor the card!

specs:
GTX 660 1.5gb
dell 3010
windows 10 21h2
275 watt pcu
core i3 3220
