Unknown error on L1 -> L0

I've been getting this event error error message for the last couple or
months or so.  I see these because I pump event log error messages to my
email.  I get anywhere between 2-10 of these daily.  I have not been able to
determine WHAT is causing them and there seems to be no consistent event
(like running a particular app) when they are generated.

I do not know what source = "nv" is.  I have no idea what "Unknown error on
L1 -> L0" means.  Microsoft doesn't give me very much info to work with here.

Any one have any ideas on this problem?

The source nv is NVidia. A guess by me but you either have a faulty
NVidia grahics card or a problematic NVidia driver.

What model graphics card do you have?

Hmmm.  I had no problems as I said up to 6 weeks or so ago.  And this week, I
just changed the Nvidia driver tot eh latest release but it didn't change
these errors.

I was running 169.21_forceware_winxp_32bit_english_whql.exe but am now
running 175.16_geforce_winxp_32bit_english_whql.exe.

I am running a BFG 7950GT OC card.

I am also running RivaTuner to bump up the overclock on the card.  I will
try disabling that and see if that is somehow causing the problem.

169.21_forceware, if I am understanding theNVidia site correctly,
remains current for the BFG 7950GT card.
http://www.nvidia.com/object/winxp_169.21_whql.html

175.16 relates to other cards.

Since I terminated the RivaTuner app, the spurious error msgs have stopped.  
I've gotten none at all today.  Thanks!
