I'm just a hobbyist but I do use Premiere Pro. All too frequently, I get an "entering power save mode" message, the monitors go blank and, essentially, a crash. Actually the computer is still running but I can't get back in control. I have to force a shutdown and reboot. The Internet is full of comments about "entering power save mode" and I've tried all the "fixes" without success. This only happens with Premiere Pro and is often associated with selecting and moving clips on the timeline. Most of my video clips and sequences are 1920x1080 and less than 15 minutes long. Recently I've discovered that frequently rendering the sequence prevents this type of crash -- so far, anyway.
I'm running Windows 7 on a Dell XPS 8700 computer with 32GB RAM, 960GB SATA III SSD, GeForce GTX 1060 6GB video card, the latest Premiere Pro CC. The main monitor is a Dell U2713H 2560x1440 and the 2nd monitor (actually not used when editing video) is an HP 2709 1920x1080.
Premiere Pro has been uninstalled and reinstalled often. Also, the version doesn't seem to matter.
I guess my real question is: Is frequent rendering a known requirement and/or problem solver with Premiere Pro?
