I'm having a very weird issue with one of my Intel AMT machines that started popping up tonight.
The monitor connected to the PC goes dark immediately after the Intel BIOS splash screen. I don't see it booting into Windows and also cannot enter the BIOS. The monitor goes into sleep mode immediately and remains dark.
When I connect VNCViewer Plus to AMT machine, I can view the desktop remotely using KVM and I see windows booting into the desktop.
Rebooting the PC, or shutting it off doesn't help. The only thing I see on the monitor attached to the PC is the Intel BIOS splash screen
When VNCViewer Plus is connected, I can see everything through VNCViewerPlus.
The Intel AMT machine has an Imtel DQ77MK mainboard and was working fine before.
Any idea what might have caused this and how this can be fixed ?
