Swapped GPU AMD to NVIDIA. Computer won't boot with new card but will with old.

I just bought an evga GeForce gtx 1060 SSC card. Upgrading from my Radeon 4850 (oldie). When I put the new card in my PC won't boot. I can get to the bios but that's it. It won't make it to the Windows splash and the screen just stays black. If I put the old card in my computer boots up just fine. A buddy of mine brought his PC over and we put the card in it, his booted just fine, so the card works and his power supply was 400W, mine is 600W. I've tried just about everything listed in forums...running DDU, trying to manually delete drivers, running with both cards at the same time, swapping PIC slots, I even upgraded to Windows 10 from 7 ultimate. I also can't boot into safe mode with the new gpu, and my mobo doesn't have on board graphics. Set up is thermaltake TR-600 600W power supply, gigabyte ga-p55-ud3r mobo, i5 650 processor, 8gb DDR3 RAM. I spent literally 15 hours on this yesterday and I'm about to give up. When I first turn the pc on the fans will start up and after a couple of seconds (probably 30ish) they stop. Don't remember if it did that on my buddy's pc or not or if it's just an auto function of the card to reduce power consumption

Theres only 1 hdmi port on the card but ill try a different cable.

What about DisplayPort or DVI-D

Maybe the HDMI port on the card is borked

We used the HDMI on my buddy's computer and it worked.

I still think an alternate cable or using one of the other video outs on the card is the next clear step.

There has been instances of non co-operation with different hdmi versions, you may need to try and install the nvidia drivers with the amd card still in. This might be true as your buddy probably had the necessary drivers already loaded for the hdmi, so the card worked. Dvi doesn't need any drivers, so should always work.

So if I got a dvi to vga or HDMI adapter would that work? And he had a 1060 as well.

The only time it seems that you'll need a different cable is the initial usage to get the drivers installed. Your buddy already has hdmi active drivers enabled, so when you stick your card in his pc, it worked. It seems you don't have hdmi active drivers yet, so just to get the screen going use a dvi cable at first. With the drivers and card installed, you should be able to revert to hdmi if you wish. Although with a 1080p/60Hz monitor dvi, hdmi, dp is all the same except dvi-d which doesn't carry analog audio, so no monitor speakers, you'd need to use the dvi-i connection and cable.
