If I leave my desk and lock the screen or leave it to go to the screen saver, when I return I often find the screen has frozen and I'm forced to hold the power button to shut down the computer.
Usually the screen is frozen with the screen save / lockscreen showing, however other times the screen returns to my desktop but it's like there is a 'sheet of glass' over everything. I can see all my documents but I save! My mouse cursor moves but I can't click on anything and the keys don't do anything. If I move the cursor to the corners of the screen the charms all slide out etc. but if I click any of them then the screen freezes completely. The hard drive light is not flashing while the screen is frozen, ie. There's no excessive disk access
I have noticed that every time the computer boots up again, after my having forced the power down, I see a 'Windows is Configuring Updates' screen. However, if I check the windows update history there are no updates listed. Unless the updates are Windows 8 RT updates ?
This is really @$%^$# me off.
It seems the graphic card driver is not compatible with Windows 8. The driver cannot be loaded correctly from sleep. Therefore, computer will reload the built-in driver and configure it at the next boot.
Please go to manufacturer's website and find the latest graphic card, install it for a test.

I've double checked my graphics card driver and it's the latest version.
I've 'unmarked' your response as an answer since my machine isn't resuming from sleep/hibernate.
My screen is set to dim but not switch off and sleep is disabled.
Thanks for the reply. Scenario 3 has the following:
1.Overclocking: Disable overclocking to see whether the issue occurs when the system is run at the correct speed.
[Me] I'm using a laptop and I haven't overclocked the cpu or gpu
2.Check the memory: Verify the memory by using a memory checker. Verify that each memory chip is the same speed and that it is configured correctly in the system.
[Me] I ran the 'built in' memory diagnostic tool (mdsched) and it found no memory issues
3.Power supply: Make sure that the power supply has enough wattage to appropriately handle the installed devices. If you added memory, installed a newer processor, installed additional drives, or added external devices, such devices can require more energy than the current power supply can provide consistently.
[Me] I'm using a laptop and I've not added or swapped any hardware. I don't usually have an external drive attached (unless doing a backup) and I don't have multiple monitors.
4.Overheating: Check whether the system is overheating by examining the internal temperature of the hardware.
[Me] I'm not sure how to do this, but I doubt the machine is overheating. It sits on my desk with plenty of space around the air vents.
5.Defaults: Reset the system back to the system defaults to see whether the issues occur when the system is running in its default configuration.
[Me] I haven't changed things in the BIOS and I'm not sure what other system defaults I would need to re-set?
