dangus :
i'd suggest disabling the integrated graphics for the CPU in the bios. plug your monitor into the new GPU and then boot the computer up. once you're into windows, it should automatically download a basic GPU driver. then, go to Nvidia's website and download their newest driver. go through the install process. you should be good to go after that.
in your BIOS, look for an option that lets you disable "integrated graphics" or disable "iGPU"
did you have a different graphics card installed before the new 1050 ti?
So I had know some things now and I will try to explain my problem.
When I start windows with new gpu it shows no signal, but I connect VGa cable to onboard vga and my GPU is found, and I disconnect vga cable. So my gpu now is found and I install newest drivers from nvidia website. After install I restart computer, and No signal detected. It doesn't matter if I try to put vga cable nothing helps, BUT if I uninstall these drivers, everything goes to back of the story. (shows no signal, I put vga cable, and gpu is found and ....)
So I think that MY gpu can't be found with drivers, and I dont understand it why.. :/
On bios, I had selected primary PCIE-16x. (No option to disable integrated)
And you asked what I had before this gpu:
I had GTX 460 v2, It worked really well for 4years maybe, and I got artifacts, so I baked it, and it worked for 1year more.
So I bought Palit gtx 1050ti stormx, I installed it, Installed latest drivers, and it worked 3 hours. (2.5 hours web-surfing; 1hour GTA V; and 30mins of Farming simulator) And it BURNED/FRIED with smell.
So I RMA it, and asked to change gpu to other, because everybody on this forum and others said that its "Bad chip" Faulty card, Dead on arrival.
So I got new/this GTX 1050 TI Gaming X msi card.
So maybe any suggestions ? Tommorow I think I will get my computer to service to look at this problem, but maybe it's something simple ? :/ (Maybe it's psu fault, but i'm using this computer now on Onboard graphics)
