New Development, updated ASUS GPU TWEAK II, released.
OK, so the system going to sleep has nothing to do with whether or not I get "Blank, black screen crashes", since I installed my ASUS R9 290x-DC2-OC edition video card. The previous card was the AMD HD 6870. A cleanup for AMD drivers, nor did multiple fresh installs of the OS help protect against "Blank, black screen crashes". Putting the AMD HD 6870 card back in would cure my "Blank, black screen crashes" and then replacing it with the ASUS R9 290x-DC2-OC edition video card my "Blank, black screen crashes" would begin again in the 2D Windows desktop again.
Doing a little more research I noticed people mentioning that while in 2D desktop mode the GPU speed jumps around a lot and some people have made new profiles for 2D desktop GPU speeds. Interesting enough, this is where my crashes happen. Using file explorer, or Internet explorer, just hanging out doing something you wouldn't expect your computer to crash from.
So I had uninstalled ASUS GPU TWEAK and was just watching speeds and temps using the Catalyst Control Center. I watched in amazement, while my computer was idle, at the numerous times the GPU would slow down to 150 MHz then Jump to 1050 MHz and then jump right back to 150 MHz. It did this a lot while IDLE. And then I crashed with a black screen, doing nothing but watching the CCC display my system properties.
Alright, off to the ASUS web site. Awesome Sauce!!! ASUS GPU Tweak II, has been released June 2015. A major upgrade. It has new profiles and displays. And something that thrilled me, the 2D's desktop profile average speed is in the 300 to 400 MHz range and rarely pops to 1050 Mhz. I mean rarely while the system is idle doing nothing. If I need fast 2D speed, the GPU speed pops right up there and works great. Idle again and it drops back down to 300 - 400 MHz range, again, and stays there.
So with this more consistent 2D desktop speed range for the GPU, I have not yet had any more "Blank, black screen crashes" while allowing the updated ASUS GPU TWEAK II to run, which starts when Windows starts.
My motherboard is a socket 1155 P8P67 EVO, one of the first motherboards out for the socket 1155 series, that does not have the internal CPU (mine is the i7 2600K) graphics adapter support available. It was left out by design in this motherboard. I don't think that has anything to do with the "Blank, black screen crashes" because this system never has them when using the AMD HD 6870 video card, I just thought I would mention the hardware design for anybody following my thread.
I will continue to monitor my system and immediately post here if I have another "Blank, black screen crash" while using ASUS GPU TWEAK II, which has a more stable GPU speed for the 2D Windows Desktop default profile.
Also, FYI, my ASUS R9290x-DC2-OC has the Elpida memory chips. Some say the "Blank, black screen crash" only happens on the boards with the Elpida memory and not the Hynix memory.
