Installation of GPU leads to a black screen.
Installation of GPU leads to a black screen.
My new PC is functioning properly without a graphics card. The motherboard (Strix Z790-E), CPU (13900K) and RAM (Dominator Titanium 64GB) are all brand new. The SSD (Samsung 980 Pro) and PSU (Corsair RM1000x) come from my old build. I recently installed the graphics card (3090 FTW3) from my previous system, but I’m seeing a black screen. The monitor powers on when I turn the PC on, yet it displays no signal. I can’t reach the BIOS. I’ve tried reseating everything. The machine appears to be running fine overall—fans spin and light up, and the AIO pump is audible. The graphics card fans spin during startup and the RGB is active. The monitor connects via the graphics card’s HDMI port. As I was about to post this, I switched to the motherboard’s HDMI and everything worked again, letting me access the desktop. In Task Manager, the 3090 isn’t listed; only Intel UHD Graphics appears. This suggests I should be able to enter BIOS with the graphics card installed, but via the motherboard’s HDMI. I’m hoping someone can help me further.
It turned out the problem was with the driver. In Device Manager I saw Windows Display Adapter reporting error code 43. After updating the driver, the GPU appeared. Restarted, connected via HDMI, and it functioned properly. Updated October 13, 2023 by lerodemmy Solution found
