Well, strictly speaking my computer has not fallen over in the literal sense, nor has it gone BOOM! - however, it does appear that my primary harddrive has committed suicide, and bled zeros and ones all over the place. I simply can't start the computer, as it claims it can't find NTLDR. Until I have fixed this issue, I'll be pretty much offline. I will, most likely, take the opportunity for a clean re-install - Windwos has been a touch wonky for me the last year or so.
