[SOLVED] GPU problem

[ILFireD]

hi everyone

i need some help with graphics card that stopped working.
i had a power surge in my apartment and when the pc crashed my graphics card stopped working. i have 2 screens, only one lit up and i got the error:
"unsupported graphics card - there is a problem with your graphics card. please ensure your card meets the minimum system requirements and that you have the latest drivers installed."
i checked the driver and it was updated.
i tried using stronger/newer graphics card and i got the same message (even after installing the newest driver).
i tried weaker/older graphics card and it works fine.

one more thing, when the problematic graphics cards are connected i can see in the device manager that the graphics card is recognized but it shows an error.


my PC specs:
cpu - I7-6700 3.4GHz 8MB 1151 tray
power supply - tr2 challenger 500w thermaltake
motherboard - B150M-A m.2 1151 DDR4 2400MHz

graphics cards:
original - geforce GTX1060 itx 6gb
newer - geforce dual gtx 1660 super OC 6gb
older - geforce gtx 750 ti

I'm lost, I'll appreciate any advice on how to solve it.

It sounds like a PSU issue. Thermaltake PSUs are notorious for their bad quality in the first place.

Try the gpu in another pc to verify but i would highly suggest you swap that psu with a reliable one.
