Apparentlyt dead AGP video card?

[jaster]

Ti-4200 apparently died. No video when installed in 2 different PCs. GPU
fan doesn't run.

I was wondering is it dead dead? As in replace it and don't look back?

You can look back if you like, you wont get turned to a pillar of salt.

Bury it in a nice place.

Maybe the fan died first, and then it overheated ?

Or whatever power source is used by the fan, is no
longer providing power. Have you visually inspected the
card for obvious defects (burnt stuff, leaking caps, etc) ?
It could be there is something waiting to tell you
it is dead dead.

It's rare to find a piece of elctronics that CAN'T be revived with
component level repair, and enough skill. But it is very, very, very
common to find repairs that cost more that the replcement cost. Yours
falls into the second category.

On the other hand, it could be that this card, in order to protect
itself WON'T run without a working fan. It may be possible to replace
the fan. But only if you can do the work yourself.


On the other, other hand, you can get a reasonably priced replacement,
too.

Agreed, GPU is probably damaged from failed fan,
particularly on Ti4200 cards while didn't have very massive
metal 'sinks, were often no more than a thin ~5cm diameter
circular plate with decorative metal risers to shield or
support the fan.

AFAIK no Ti4200 had such a protection mechanism, they tended
to have fan straight from a thermal diode biased transistor
type supply from the 12V rail... not that they adjusted to
temp very well, the diode was on the PCB near the fan header
rather than near anything producing heat.

Thanks

I agree it's possible the PSU is also failing as one of the case fans has
also stopped. But I switched video cards and both systems work with the working
card. That's how I figured the Ti4200 died.

Thanks again Kony and Paulmd.
I was surprised as this is the first time I remember a video card
failing. This is was a Ti-4200-128 (4x AGP) with a fan. I wondered if
replacing the fan would fix the card, though I have already replaced it.

But I'll send it to the scrap heap or trade-up credit.

Well there's a first time for everything... but sure, take
any of the more modern moderately heat-producing cards and
once the fan stops it's days are numbered.

The shame is how poor the fans usually are, even on many
very expensive cards. Any card I've owned that was worth
over $75 I refitted with a different heatsink and fan...
usually an old socket 7, 370, or some other less commonly
known format heatsink I had leftover from yesteryear. If
the hunk of metal will allow (or you can devise an alternate
method, I've sometimes tapped holes and other times even
epoxied in brass threaded inserts) a quality major
manufacturer fan at least 50mm x 15mm at very low RPM, it'll
allow not only years of life but be far quieter the whole
time.

In other cases you end up having to pull off the fan every
year or so and clean out the dust and lube it with a drop of
thick oil. Some will suggest using thin oil which doesn't
work well at all on these tiny fans, their bearings are too
shallow and the horizontal orientation results in the oil
quickly running out of the bearing.

This is was a Ti-4200-128 (4x AGP) with a fan. I wondered if
replacing the fan would fix the card, though I have already replaced it.

If the system is left turned off so that it's cooled down
completely, if the system (video) doesn't then come on
immediately when turned on, the card is toast. Even with no
fan running it would work until it had overheated which is
at least > 1 minute with the fan stopped.
