I just got a Z97-WS with a i7-4790k, liquid cooler, and tons of fans.... and on Windows 10 x64 Enterprise. I rebuild the OS with nearly every build of Win 10.
Problem: Once I install the OS and all my software, I get ready to run the 5-way optimization. BEFORE I run it, I'm able to select the Auto Power Saving Formula and it sticks. No problem.
As soon as I run an Optimization, I can't pick Auto any more. Picking Auto makes AIS 3 dim and I see the spinner as if it were really changing the profile, except it hangs and locks the PC. The only way out is to hard-boot. So, I can't use Auto.
Anyone else have this problem or have suggestions on how to deal with this?
