How do I locate an unsigned driver?

[Quentin]

Vista 64 started up in test mode this morning, so it's complaining about an
unsigned driver. Unfortunately there's nothing in the Event logs to identify
the driver, and I've checked Device Manager too. I had a failed install of a
utility called HMonitor yesterday, but I uninstalled that immediately. I did
a System Restore to an earlier date but that didn't get rid of Test Mode.

Windows Help says nothing, nor does the MS KB. Searching online just gives
me instrctions on how to turn the message off and allow unsigned drivers.

I can get rid of the message by using BCDEdit, but I'd really rather get to
the root of the problem.

And if anyone from MS is reading this, please, if Vista is complaining about
something, please let the user know what it is!

Thanks, but I'm none the wiser. I can't spot anything amiss and inthe Signed
Drivers section it says that the signatures for a whole load of the inbuilt
services - like the Windows Firewall Authorisation driver and HTTP - are 'Not
Available' - so it's actually worse than useless in this regard.

Or am I missing something?

My Motherboard / BIOS gives some reboot option like F8 that allows you
to clean up failed signed driver install, although it's a little obscure
how to do it - without that option I'd have been hosed on at least one
occasion.

I don't have the machine here right now so can't give details except
it's a "Gigabyte" MB.

I suspect it's a driver that is related to the monitoring tool you
mentioned, and if so probably needs access to the Vista 64 Kernal. I had
one similar tool which was okay - it gave the error but worked - but
that ran only on demand. Is there some remnant of this tool left on your
machine that is trying to run automatically from a registry key or
something? Maybe if it is then you can locate the key and the problem
will safely just go away?

Try this and see if you can spot it.

I'd forgotten about Verifier. But it says that there are no unsigned drivers!
