Hey guys,

Just finished a build and have been researching "no display on new pc build" for hours now.

Here's what I've tried:
  • Reseating all connections
  • Multiple displays (also confirmed display is working with other device)
  • mobo DisplayPort instead of HDMI port
  • Different cables
  • Checked CPU for bent pins (all good)
  • Removed Graphics Card to test onboard video (Still doesn't work)
  • Cleared CMOS by removing battery for 10 mins + Jumper reset
  • Disconnected hard drives
  • Tried each RAM stick individually in all four possible slots
  • Removed mouse and keyboard
So I just got done building this beast and it has yet to see the light of a display. Haven't seen BIOS once. It doesn't have a mobo speaker so I can't hear any beeps. All fans and other components are running.

Here's my NEW build (pcpartpicker's Magnificent AMD Build):
  • AMD Ryzen 7 3700X 3.6 GHz 8-Core Processor
  • Corsair H115i RGB PLATINUM 97 CFM Liquid CPU Cooler
  • ASRock X570 Phantom Gaming 4 ATX AM4 Motherboard (Perhaps faulty?)
  • OLOy WarHawk RGB 32 GB (2 x 16 GB) DDR4-3200 Memory
  • Hitachi Ultrastar 7K4000 4 TB 3.5" 7200RPM Internal Hard Drive
  • NVIDIA GeForce RTX 2080 SUPER 8 GB Video Card
  • Lian Li PC-O11 Dynamic ATX Full Tower Case
  • EVGA 750 W 80+ Gold Certified Semi-modular ATX Power Supply
  • Noctua NF-F12 PWM chromax.black.swap 54.97 CFM 120 mm Fan (x2)
  • Team Group GX1 2.5" 960GB SATA III Internal Solid State Drive (SSD)
Bad motherboard???


Thank you!

Try a video card

Hey guys. Thanks for the responses. I've put the card in and made certain of solid connection. Now when I boot, the mobo is reporting an issue in the VGA and boot LEDs. Still nothing on monitor.

I don't know guys. Same issue. Neither of those efforts worked unfortunately. It sounds like the card is trying to boot itself about 3 times. It's onboard fans rev up for about 2 seconds at a time (3 times).

Begin by restarting your system. Press the power button for a few seconds until the system reboots. Most motherboards power-on self-test (POST) or beep when there's a booting issue. If that is the case, refer to the motherboard manual to interpret.
 
Oh damn! I put the board back in the first slot, doubled up power to the card as well as the CPU, and then (which I think was the key) I pulled the battery for 10 minutes and reset CMOS. I'm seeing the light!!! Thank you guys so much! Rock on.

Quick edit: I removed the second power cables from both the CPU and GPU (now they're back to using a single cable / default amount of power) and things are still working.
