monitor goes into power saving mode

Hello,

My monitor randomly goes into power saving mode and doesn't snap out of it unless I turn off my PSU and restart the computer. It's very frustrating, especially since I just built my PC, and don't want any components to be damaged. 

This is the monitor I have:

E2414H (digital-DVI)

gpu : gtx 970

The drivers to my gpu and monitor are up to date. I have went through all of the windows power settings to "never sleep" and never turn off my monitor. The problem only primarily when I'm in a game, but has occasionally occurred when I'm on the desktop. I honestly think it's a problem with my monitor because my computer used to not do this, but I'm open to any ideas, and help with troubleshooting.

Is there a way to completely turn off power saving mode? I've read similar posts after Google searching and this seems to be a consistent problem with dell monitors.
