I gave you the simple answer... *grin* maybe some of the pre-press pros we have in the forum will chime in with more detailed answers... Iknow Scott and a few others are really experienced with this type of problem and hopefully can point you in the right direction.  For me, the CMS gives me output that is 'good enough' since nothing I do is color critical.  

I have experienced situations where my QMS Colorscript gives me output that matches my screen, but the same stuff from the printers will be off a tad, though not as severe as gray turning brown.  Anyway.. beyond recommending CMS if you are not using, I am a bit out of my league. 

You said the problem happened overnight. Is it a display or video problem maybe? Do other documents that used to display fine look different on screen now?   

Did you install any applications during the time this shift happened? I am just tossing out possibilities, here.
