Vista went retro black and white on me, even w/ new driver

Sooo, one day I booted up and Vista was black and white. No color, just like a black and white television. Kinda cool. I usually use XP anyway, and a couple of days later when I went back to Vista I got a BSOD just after logging in, restarted, logged into Vista and another BSOD. So I left Vista alone and worked in XP again for a while. Now when I'm in Vista I don't get the BSOD anymore, but my display is still black and white. And I just updated the ATI drivers from the ones for RC1 to the ones for RC2.

XP works in color, as it should, so it's not my monitor's problem. I took a screenshot of my desktop in Vista and opened it in XP and, sure enough, it's in color. Also, the loading bar for Vista is also in color, green as it should be, but once it gets to the sign-in window everything is black and white.

Any ideas?

EDIT: P.S. my external LCD monitor is displayed in color while my ThinkPad's LCD is still black and white. Weird. I never messed with any color profiles, on either driver set.

Nevermind, I fixed it. I had to uninstall the driver through device manager, not vista's 'add/remove programs' and reinstall the RC2 ATI driver.

Yeah, that happened to me once too, but only on my external monitor. I thought my lcd monitor broke at first. I think it randomly fixed itself or something. Extremely strange bug.
