Chip failures are really weird, and not as well understood as a lot
of people would like.
Sure, temperature can cause problems over time, but in the
case of the Nvidia GPU, the phrase 'time bomb' is pretty much
correct. I had three of five thinkpads with them fail, with
the 4th crapping out and I still haven't gotten my hands on
it. So yeah, Nvidia made a turkey.
I think wikipedia might have some stuff on IC failures; look at
http://en.wikipedia.org/wiki/Integrated_circuit and go from there.
Yes, your 5th year was a good investment. ;-)

George and Steve, thanks for this info.
I've had this machine for over 4 years (and Lenovo just last month renewed
my warranty for a 5th--and they say final--year) and this has only started
recently. Is it possible that the faulty chip is only starting to "go bad"
after all this time? Might it be a sign of other issues (like the fan not
cooling sufficiently) that are causing the chip to start to fail? Maybe a
real good thing I got that extra year. :) I assume it would be a covered
replacement.

I get the feeling that George might be right. Nvidia, the gift that keeps
giving!
However, you should try using another video driver and see what happens.
I might rip the driver out and let Windows discover/find one. See what
happens.
That, and/or find Linux live CD that knows about the NVidia card, and see
what that does.

I believe that your GPU might be on its way out...do a little research on
faulty nvidia chips that T61/p (along with Macs, Dell, HP...) shipped with.
Good luck.

Subject: [Thinkpad] Extremely Annoying Screen Artifacts
I have a T61p running Windows 7 (64-bit) and recently I started
experiencing a very annoying thing happening. When I right-click on
menu items in various applications (including Windows Explorer)
certain menu selections remain on the screen (white text on a blue
banner). This graphic sits on top of any other windows I open and the
only thing that I have come up with to clear it is to restart the machine.
Anyone else ever see this happen or know how to get rid of it?
One other thing that may or may not have anything to do with this is
that the Lenovo's Message Center periodically shows a flag and when I
click on it, it tells me about a problem with the nVidia driver.
However, when I click on the link to get a new driver, it tells me
that I don't have a connection to the internet which is obviously not
correct. This message about not being able to connect only happens on
reports of nVidia problems and not on other problems that get flagged.
Thanks.
