Photoshop: Monitor colour profile goes haywire.

I had this problem with PS CS5, and just experienced it again with PS CS6. For some reason that I cannot identify (I cannot provide steps to reproduce), PS in pretty much default using standard sRGB, suddenly decides to render all colours as though it is in CMYK mode. No change occurred to any calibration files. Basically, it appears that it references the wrong colour profile file. Screen-grab and paste a #ff0000 block twice, and it is already a very dark brown.
Running Windows colour calibration manages to get it back to almost-correct colours, but with the discrepancy to be expected from trying to make the changes manually.
That it can be almost-corrected is an issue in itself - it should not happen in the first place as the monitor profile is not changed. The manual solution effectively messes up the colours.

It could be that the OS is supplying a different profile for your display, or that your video card driver is having a problem running the shader that does color corection.

If this goes away when you turn off GPU drawing, then it's the GPU driver.

But you describe it going away when running display calibration - so it sounds like the OS is telling Photoshop that there is a new profile for your display, and Photoshop is picking up the new profile like it should (and the profile is wrong). You might want to check your system for any color calibration utilities that might be causing conflicts with the OS.
