hmmmm, this is a vexing one!!!! im not sure if this post will help. i see that you are using a pc. on a mac you can run coloursync utility, kinda like a disk utility but for all the colour gammas and profiles and all that good stuff on the entire machine. it will tell you that x number of profiles over time have shifted and need to be repaired. click ok and it repairs it all for you. check if your pc has a similar utilty and run it. you will be shocked at how much things get damaged! if it does not solve the problem at least all yor profiles will be as good as new.
