Hello everyone, I am in dire need of assistance. I recently bought parts for a new pc build and I finally have it all put together but I have a problem... When I turn on the fully assembled PC it outputs a black screen. I can't get to the bios, or install an OS. I tried the graphics card in another system, and it didnt output. But I also tried a different but older card in my new motherboard and still no output. The fans don't spin on the graphics card, and the motherboard powers fully on with no error beeps. I tried resetting the CMOS and changing the battery, I tried using both the DVI as well as HDMI and nothing. Everything is plugged in, graphics card and motherboard both have their respective cables. I've double checked all part compatibility and there seems to be no issue. The graphics card is in the slot closest to the CPU and I have dual 16GB ram sticks in slots 1 and 3 respectively. The motherboard is an ASRock x99 Fatality Proffessional, and the graphics card is an Asus Geforce GTX 1070. I have a 750W powersupply so there should not be a power issue. Can someone please help?
