So I just built my first PC:
GPU:EVGA GTX1070 FE
MOBO: Asus z170a
PSU:EVGA 750W 80+ Gold.
So after I installed everything, then powered it on, the monitor showed no signal. I've tried replace all psu cables, tried using a different pci-e slot, tried with one RAM in all different slots, and use a different monitor. Finally I tried taking the battery out from MOBO for 20 min! Now, the monitor will turn on without a GPU installed and only via VGA cable (not working with HDMI), but my GPU doesn't have VGA port. I was going to use a VGA-HDMI converter but the manual says "please do not connect to 'DVI to VGA' adapter." since I can go to the BIOS without my GPU installed, I tried set the primary to pci-e and others, save and exit. Then it will just reboot and goes back to AUTO. I really don't know what to do now. btw the gpu lights up and fans are spinning, just no signal..

HDMI is just not working...even on my MOBO. I heard that drivers need to be downloaded for using HDMI, I haven't tried that yet. No beeps from the MOBO neither any red lights.
