Windows Activation Problem

Hey all, hoping you can help me here. Did a fresh install of Windows 7 about 2 months ago and everything has been fine. The last couple of days though, been getting a message saying I need to activate my Windows copy (something I was sure I'd already done). I've had this on my laptop for a while now as well, but for now I just want to sort the desktop out. The only real issues with it is it seems to be stopping me from updating windows (something I've realised I haven't done since the install) and keeps turning my desktop wallpaper black. Below is the MGADiag report.

Thanks in advance for your help.

Have you tried the telephone way.

It looks fine to me - what makes you think it may not be legit?

We will possibly get a little more detail if you install the WAT Update - KB971033 - but I doubt that it will change anything.
