Sounds to me as if your sRGB profile file has been corrupted by the windows applet.
Have you tried downloading a fresh ICC sRGB profile file from ICC web site.
There are 2 versions there with BPC and without. Windows uses the one with BPC.

And every one said, 'If we only live,
We too will go to sea in a Sieve,---
To the hills of the Chankly Bore!'
Far and few, far and few, Are the lands where the Jumblies live;
Their heads are green, and their hands are blue, And they went to sea in a Sieve.
