I’ve had a number of problems with Win 8 that all seem to come down to installing Win 8 in UEFI mode and the default Win 8 Fast Boot setting.
There is some info about Win 8 Fast Boot here:

For fast boot to work you need a mobo that supports it and a GPU that supports Graphics Output Protocol (GOP).
No ATI cards support this function apart from a few 7 series boards from PowerColour. Some of the Nvidia vendors will supply a special UEFI GOP bios update for the 6 series cards, but the update is not available other than via a support request.
Fast Boot is enabled by default, yet unless you have a mobo and GPU that support it will not work as intended.
Essentially when you shut down your PC it will not actually shut down. Instead it will hibernate whatever was running at the time and write it to disk on a hidden partition. When you start up all the services running at the point of “shut down” will restart and boot up will take a couple of seconds.
Some major problems that can occur:
· Services don’t always restart
· If you change your hardware/ software set up it can cause problems when the PC restarts
· When the OS is installed in UEFI mode problems can arise such as not being able to unblock a frozen state SSD to run a secure erase
· BIOS updates can get messed up. (Crucial warned against updating the latest f/w in UEFI mode and I had to change my mobo BIOS chip twice after bad updates in UEFI mode).
· Extended I/0 response times
· Weird off set partitions
Any benefit of fast boot is not going to materialize until GPU cards support it, yet it’s the default Win 8 setting. The shutdown menu in Win 8 should be a lot clearer and give an option for a cold shut down if you have updated hardware/ software.
The easy way to disable it is to use the “powercfg/hibernate off” command via CMD.
Unless I’m missing something I see no benefit of installing an OS in UEFI mode. All I have seen is problems.
Since it didn't really have anything to do with Mem & Storage, moved to Operating Systems
