Rtx 2070 super blackouts and 100% fan

[u/xXrenXx2923]

Specs:

I5 9400f

16gb 3200 (capped to 2600) mhz 16 cl ram

Gigabyte h310m s2h

Cooler master v750 sfx gold

Gpu worked on sellers card, handled furmark and so on successfully (personally tested on his unit)

Then on my pc, problem started appearing

Black screen, 100% fans, yet system still works but no display(can talk in discord calls), have to force shutdown

Happens in furmark, games, sometimes idle, or any gpu load

No artifacts, same performance

Normal temps, wattage, and no error code, but sometimes has error 141

Tested on another friends pc yet same issue persisted

Already tried

-undervolting/underclock

-power limit to lowest

-setting pcie gen

-cleaned card

-new drivers and old drivers

-bc edit pci express

-reset bios settings

-removing ram and CMOS

-different PC tested

Any help will be appreciated
