There's also "canned air", which is just what it sounds like. A bit more
vigorous than a bulb for camera lens cleaning.

I've seen vacuum cleaners advertised as static-free. I don't know if
that makes any difference, but you might want to consider it if you're
going to vacuum directly inside the case.

But limited contents.

I used to see cans of compressed air that came with a hand pump so they
could be refilled. I never managed to get my hands on one to see if they
worked well, and haven't seen them for a while (the store that sold them
has since gone out of business).
But I imagine they still exist *somewhere*.

Try showing the temperature in parallel with running the GPU (eg 3D game in
a window), IIRC when I did those sorts of tests before, the GPU temperature
dropped rapidly very quickly (eg 10-15 degrees in just a second after
exiting a game).

Actual chip core temperature of 55 degrees seems fine to me, if it got to 80
or 90 I would start to get worried.

One very easy and cheap way to check...

Surely that's a rather rare failure mode on a graphics card? That seems
to me more like the kind of thing where you get a brand new card and
it's DOA. This card has been installed and running without issue for years.

Oh, OK. Generally my CPU doesn't get anywhere near that hot - but then,
I guess my CPU doesn't develop several hundred GFLOPS...

Well, I did it anyway, just for the hell of it. Next time I play, I'll
see if it makes any difference.
(The wonderful thing about intermittent faults is that you can never
truly know if they are fixed.)

I own this. I'll give it a try later. If it *outside* of my PC is
anything to go by, it's probably about time... o_O

About the same as getting some bad RAM bits in your normal PC RAM probably.

I had the RAM in my desktop machine at work partially fail after some time.
It started when dealing with big zip files, it would complain that the CRC
check didn't match up, even though I had just downloaded it. Then it would
blue-screen randomly, and gradually got more frequent. I did the memcheck86
or whatever it was and there was an area of RAM that was totally corrupt,
it's a wonder Windows even booted, let alone worked normally most of the
time. Replaced the RAM and very reliable now.
I had the same with my nVidia Ti4200 graphics card, actually identical
symptoms to you, random triangles flickering across the screen. Gradually
got worse over time, and also while playing a game until it crashed. Tried
it in my sisters PC and the same symptoms. I didn't bother trying to figure
out the cause, but just assumed it was bad RAM.

Well, you'd think. ;-)
I've bought brand new RAM sticks to find that they're defective, and
I've occasionally damaged one inserting or removing it, but never seen
one just fail during normal use. They seem to be quite reliable.

Yeah, RAM failures cause weird crap to happen. Depending on where in RAM
the problem is, it often only causes problems when you try to do certain
things. (But what with virtual memory, it's quite hard to predict when
it will or won't show up a problem.) Diagnosing RAM faults without a
real RAM tester is just Not Fun...

Well, since the RAM isn't replaceable on a graphics card, I guess it
really just boils down to "does this graphics card work properly or not?"

Not if it has been overheating.
Have you checked the temperature of the video RAM?

True, but since the GPU generates far more heat than a block of RAM does...

I don't have a way to do that.
