This GTX 780 operates only in highly defined conditions.
Previously I faced a problem with my GTX 780 not displaying at all, but after some guidance it became clear. The DP (main screen) needs to be connected to the motherboard's iGPU, and the HDMI (second screen) must link to the 780. I’m curious if there’s a reason for this setup and whether I can fix it so games select the HD 770 instead. Any suggestions would be appreciated!
Open Device Manager, look for the GTX 780 in display adapters. If a yellow warning appears, right-click and choose properties. Review the device status. Capture a screenshot if an error code shows up. Did you acquire this card from a second-hand source? Have it functioned before?
I acquired it used a couple of years ago. It was my primary for some time and performed well, never faced any problems. The card functions properly, games can utilize it. However, I can't post without the DP in the iGPU. Device manager shows "No DP signal" and then it shuts down.
It can display the motherboard splash screen when trying to boot via Windows, but it only fails to start. Download DDU for this purpose. When you first launch the program, select "start in safe mode." Once in safe mode, DDU will launch automatically. In the options menu, set "prevent windows update from installing drivers," then pick "Nvidia GPU" and choose "clean and shutdown, for installing new GPU." The PC will power off. Reconnect the display cables to the GPU and restart the system. After booting into Windows, install the GPU drivers, ensuring legacy drivers are included.
It might stem from a conflict with current driver versions. Consider reverting to older driver updates until stability returns.
I’d prefer to revert one version at a time. It happened to me with my old GTX 560; after rolling it back, everything functioned properly. Sometimes the cards get outdated, and modern drivers don’t work well then.
