x99 ITX motherboard not sleeping

Message Topic Search Topic Options Post Reply Create New Topic Printable Version Translate Topic

   Hi all.
I got a new ASRock x99 ITX motherboard.    All seems to work well.
But when waking the PC up from sleep, it turns on for 5-10secs. then shuts down.
After reading other forums, it may be the video card or Display Port.
To "fix"  the problem, I replaced an nVidia 680 GTX  old AMD 4870 GPU and that can recover from sleep easily.
This makes me curiously optimistic and makes me think nothing is wrong with any of the hardware,

Yes, I updated all drivers and BIOS and this is a new install with only a keyboard and mouse plugged in.

The only thing I didn't try yet was updating the GPU BIOS.

Any ideas?
thanks!

My rig:
Windows 10 Home  x64
ASRock x99 ITX
Intel Xeon E5-1650 v3 Haswell-EP
Crucial 32GB (2 x 16GB) 288-Pin DDR4 SDRAM ECC 
SAMSUNG SM951
nVidia 680 GTX
Seasonic 660 Platinum

	When the PC wakes from Sleep for the 5 - 10 seconds, do you get a signal to the monitor, and the desktop shown on the screen? After that, the board goes into a full shut down, is that correct? That is the opposite of the Sleep issues seen with the P67 chipset boards. When waking from Sleep the video card would not respond in the time frame that Windows expected (required) it to do, and the result was no video signal to the monitor, but the PC remained on otherwise. The GPU BIOS is worth a try updating, but may do nothing.
