Windows authentication

Hello,

Has anyone else had problems with google chrome and vista?

I wonder if anyone can help. My computer ha recently started telling me that my copy of windows did not pass genuine validation. It's always passed before, and it is genuine. according to the help page the message points me to it says a I've installed something that isn't compatible with vista. They only thing I can think of that I've installed recently is whatever is required to use google wave, namely google chrome?

A system restore on my computer didn't fix it. If anyone can help I'd be very grateful.

Thanks,

Xanda

p.s. it also seems I can't access my computer control panel now? What is going on?

More details:

Error:0xC004D401
Description:
The security processor reported a system file mismatch error

Thanks again,
Xanda
