What version of chrome? Since it's chrome effecting only, try not using chrome and open a ticket with TAC.
FWIW I would update to the latest chrome version, I run "version 44.0.2403.130 (64-bit)" which i believe is the latest for my OS. I have or seen very little issues with CHROME, and most of my stuff is on MR3_18 and 5.0.x.
