Same things happens to my PC like this Tom's hardware guy
http://www.tomshardware.com/answers/id-2100570/asus-maximus-extreme-windows-failed-fast-startup-erro...The following happens last night:
1. Event 6008: The previous system shutdown at 11:17:37 PM on 4/17/2014 was unexpected.
I did not know something went wrong (no BSOD) as my system settings for Startup and Recovery were:
* Write and event to the system log + automatic restart with automatic memory dump.
2. So this morning, the computer took longer time to log in (this is a warning sign). I check the event viewer right away, and sure enough, there was one critical event:
Event 41: The system has rebooted without cleanly shutting down first. This error could be caused if the system stopped responding, crashed, or lost power unexpectedly. 4/18/2014 7:12:50 AM
and a Kernel-boot error, Event 29: Windows failed fast startup with error status 0xC00000D4. 4/18/2014 7:12:48 AM
Please note that the fast startup option was still enabled at that time.
3. So what I have done is to change my system settings for Startup and Recovery to:
* Write and event to the system log + automatic restart has been disabled + choose small memory dump in %SystemRoot%\Minidump
By doing so, I will be able to at least have dmp files in the minidump subdirectly.
4. I also disable the fast startup option as I am running the OS with the SSD, and the boot time is still pretty fast.
My hypothesis is that somewhat is not quite right with the fast startup option, but I would have to wait to see whether the issue still remains or not.
