Question Display not being recognized by GPU HDMI, GPU DisplayPort, or MB HDMI

[pamplemoose81]

Built PC one year ago. Went into office tonight and nothing displaying on monitor using HDMI or Display Port on GPU. Then:

1. Tried motherboard HDMI
2. Removed GPU and tried motherboard HDMI again
3. Removed RAM in slot 2
4. Swapped RAM in slot 1
5. Held in mb reset button for 5 seconds
6. Removed mb battery for 5 min, tried mb reset button again
7. Tried different display and cords

MB is flashing CPU LED and sounds one long beep followed by two short beeps. Figured I'd try replacing motherboard next. Thoughts?

Forget about motherboard video out connections, your CPU doesn't have IGPU so they wouldn't work anyway.
Your RAM should be in A2 and B2 slots only.
Try GPU in another PCIe port.
Replug all power connections.

Ah, didn't realize the motherboard video out connections wouldn't work, thanks. So issue could be GPU afterall... I'll try a different slot and power connections. RAM is in correct positions.
