I have the same problem. I have Chrome on Vista and Windows 7 but haven't experienced the same issue with both versions. Now, I had major problem with my PC so had to install XP. It's new installation, few days old but Chrome always crashes and I don't really know why?
I remember that I had the same issue 2 years back when I was still using XP and before moving to Vista.
I wish someone could enlighten us!
