Bizzar Word Behaviou (Random Raw Data Appearing??)

[craig.office]

After an unpredictable (10-30min) amount of time, MS Office a perfeectly fine MS word document (Office 2010). Suddenly has normal text change to what looks like Wingdings!


Then when I go to save the document, I can't as it only saves a 0K file.

Any advice welcome?

Note: I've done tones of hardware tests and yet to find any issues!
