Spontanous Monitor Power Save Mode

I have a Sweetwater Creation Station 450+ PC running Windows 10 connected via DisplayPort to two Dell P2415Q monitors, daisy chained and being used as extended displays.  I am mostly using ProTools 12.5 extended across both monitors. About every 2 - 5 minutes both monitors randomly go "black" entering Power Save Mode. Shutting off and turning back on the first monitor in the series "wakes up" both monitors, but things that were visible on both monitors are visible only on the primary monitor. I haven't noticed this happening when using another computer (Dell Inspiron laptop) running Windows 7 is connected in the same configuration to the same monitors using miniDisplayPort ouput/cables. This spontaneous loss of signal is incredibly disruptive to my workflow. Appreciate your help!

Look in Control Panel, Security and Maintenance, pull down Maintenance, and run Reliability History. Do you have any hardware errors when the monitor goes black?  

You could have a Video Driver issue causing this. Update BIOS, Chipset and Video Driver (all 3).

Need to have someone in tech support work with me on updating BIOS, Chipset and Video Driver since they are not available over the weekend. The temporary fix was to connect one monitor via HDMI, the other monitor via DP, adjust the resolution down to 2K for each monitor and apply settings. This works well so I am not sure I am going to play with the BIOS/Chipset updates. at this point.

If the workaround works for you, that is great.

There is no issue in updating drivers as mentioned and this should be done anyway on any machine. So get your tech support to help you with the drivers as mentioned.
