Hey guys,

So I built a new PC today - Motherboard is a Gigabyte GA-B150-HD3P and the GPU is a Gigabyte GeForce GTX 1060 G1 Gaming 6G. When I start the PC, the fans start spinning and then turn off for some reason.
I have my monitor plugged into the GPU with a HDMI cable and I have visual, but my GPU's fans are not spinning anymore and my system doesn't detect the card. It's connected to a 500W PSU, which should be enough.
I've been searching the internet for a couple of hours and I'm kind of pulling my hair out here.

Can you help me out please :(

I installed it once and restarted, then the Intel HD Graphics 530 showed up.
Then I tried to install it again (multiple times) and my PC gave a message that something went wrong and it needs to restart, and does so.
