HI, i received a modified RTX 2080ti (arctic xtreme IV cooling) recently from one of my family members. Installed the card, updated bios, graphics drivers update and clean install, reset CMOS battery, but when I do anything graphics intensive with the card like a benchmark on 3Dmark, the screen just goes black. when i put my older GTX-980 SC in the same PCIe slot and power connections it works just fine, no bugs.

How could i fix this, or could it just be a faulty card?


PC Specs:
Motherboard - Z170 Pro Gaming
CPU - Intel Core I7-6700K 4.0ghz
GPU - RTX 2080TI 11gb
RAM - Gskil Ripjaws 16gb 3200mhz
PSU - Seasonic Focus GX-850 (850 watt)

- Note I am running 2 displays (main with HDMI and second monitor with a display port)
 
Sounds faulty you took all the correct steps when installing it clean install etc. Take it to desktop run furmark and see what it does. Lmk if it black screens.
