Not receiving any responses I looked around for a bit but was not finding anything that corrected the issue I was getting with Windows 8.1 hanging/freezing, but being diligent I found out a pretty simple fix that actually works.
I have looked through several forums and there is a ton of different things that people are suggesting to fix this issue like running Windows troubleshooter and several other things that did nothing for me at all except waste a ton of time, but I'll help you cut right through the crap pie to fix this issue.
If anyone out there is having this hanging/freezing issue after updating Windows 8 home to 8.1 try this out I found it and it fixed the issue the first time after weeks of several other things that did nothing.http://www.youtube.com/watch?v=oYQUJosPbE8
There you go follow what he said, simple, simple fix!!! I can't believe I forgot the update would probably change those power/monitor settings, facepalm! Owell, leave to Windows software to set monitor/power settings to something that would make their software unstable. Hopefully this will fix your issue if not best of luck.
P.S. I want to note that I set never for both options in power save settings.
P.S.S. I found that after changing the power/monitor settings the screen saver takes almost a minute or two to kick in but after the screen saver gets started it will respond to keyboard or the mouse and no longer hang/freeze up and then require a system reboot.
