3) shut down (either way as above) and turn off the displays, and stay on until the computer times it out.

actually, i think that HybridBoot does not make that much as i thought, the real thing is msconfig.exe, that helps booting.
by disabling HB didn't make that big difference as i thought... only thing i discovered was shutdown behaivour

hello
i'm facing the same problem,

Hello

It seems to be driver-related: Try to install the latest chipset drivers for you motherboard from Intel. This helped me fix some bsod's some time ago.
I's not guaranteed to work since W8 Dev Prev. it's still pre-beta. You should get the Windows 7 drivers for your intel chipset. (It should be chipset 5 => for a first generation i5 - i3 processor and higher for later versions). Get the zip version and install manually with Device Manager within Windows. Usually check all system devices (pci bridges included) and your sata/ide devices. (intel usb drivers are also included).

Why not install the executable? Because it doesn't installs much in the first place (checked with Device Manager).

Good luck

Here is my latest try.
All driver are up to date. I did uninstall some program, then closing down all active running, still it shut down unexpectedly.
I will continue to sort it out, while thinking is there something wrong with .Net framework 4.5?

If you didn' t find any viruses and the drivers are ok, then you can try disabling .Net 4.5 (Windows components).

My brother managed to install windows 8 on a pentium 3 with 512mb, and it had a lot of randomly blue screens but it was also usable (too slow in my opinion). But It's normal to see more blue screens than in a release version.

I hope you'll find something out for you problem.

Have ruled out things..
Wonder why it still occurs. The same behavior to all three of my rigs.
The best way so far is letting it restart, then again, shut it down from login screen.
