Here we go. Configuration is:

ASUS ROG STRIX B360-G
I5-8600 (65w)
16GB G.Skill Ripjaws F4-2666C15D-16GVR
SSD M.2 Samsung 860 EVO 500GB
EVGA GTX750

Was just booted fully in Ubuntu (16.4.02), powered down fully. Added an 8TB HGST 0f23267 drive and powers up shuts down continuously after first power up after hardware upgrade. I shut it down holding the power button off, waited a full minute. I disconnected the drive and powered on to see what was going on in bios and now no video, tried a second functional gtx750 and friggin' thing is giving me the bird. Now it will stay running, but I have no clue what is happening output on screen.

Any ideas? I tried putting a onboard speaker jumper and I don't even get BEEPS! Seriously what is going on here? Anyone anyone? Oh and I hate this board for the fact there is no code led to show what is going on during post. UGHHHH

Oh, this isn't a gaming rig it's a Plex server with 28TB of HGST datacenter goodness.
