9600XT white noise after ~1 hour of CATV

[MtnGoat]

Hi All,

This is really getting irratating:

For reasons I can't pin down, after around an hour or so (sometimes
more) of watching analog Cable TV, the sound goes to static, white
noise, pink noise, whatever. No errors in the logs no change to the
otherwise great picture and the only solution seems to be to reboot.
Changing inputs from Analog TV input doesn't help and the problem is
on all stations. Stopping and restarting the TV app has no effect.
All other sound seems fine (Windows effects, multimedia files played
with ATI or otherwise.

Specs:

ATI 9600XT on an Abit NF7-S (ver. 2) w/ most recent BIOS.
550W CoolerMaster ps

OS was just installed last week.
Windows 2000 Server fully patched.

ATI 5.13 drivers w/MMC 9.08 then updated with the latest Omega (I
realize Omegas were built on 5.12)
- One note here. when the ATI 5.13 were first installed the TV would
start and the picture would freeze after a second, sound would
continue. Omegas semed to solve that.

Nvidia's latest platform drivers for nForce 2 (v. 4.27).

Also to add, the TV signal is fine; television in the next room isnt
affected.

Thanks for any ideas on this.

Chuck

did you use driver cleaner before installing the omegas?

nope, I'm pretty sure he says you don't have to uninstall the ATI's
(but with the different versions, your point is well taken. Just not
sure this problem, which doesn't appear till after extended use, is
driver related. I'm considering doing it and starting fresh.)

Is this the card?

If you exit the TV app, is the your PC desktop image affected? If not, the
TV tuner chip could be overheating. Open your case and point a large house
fan at the card and see if the noise disappears.

That looks like it, it's a genuine ATI.

This machine is housed in a full size tower and one side is always off
for cooling and to access the innards (not doing any oc'ing or
tweaking). The fan on the card is working and everything's pretty
clean. I agree that it seems to be a cooling problem so I've placed a
desk fan near it and we'll see.

Thanks.

Hi
I remember a few years ago, the home computer was primarily used to watch to the tv.
A problem as described above ocured, except the fact that entire cable signal was in a loop when
plugged to the cable: white noise for about 5 seconds noise, 1 second clear intervals. At first I
suspected the 30 m wire. it wasn't. I remember that all the televisions in the neighborhood were
scrambling while mine was, too. I tried several methods to make things turnaround, none worked. I
was ready to give up until I simply used a groundless plug in the power point. Solved !
Hope it helps .. I was on aiw radeon 7500
Bye
Lo

Thanks Lo, but the other TV's don't suffer this. Seems to be isolated
inside my pc.

Thanks again.

Well, sadly extra cooling didn't seem to help. The noise now seems to
come and go on it's own; I can listen for a couple minutes then white
noise for a couple minutes then it clears (actually it sounds like it
comes close to clearing a couple times, then clears), then returns.

This card was bought new in May of '04. The machine is on 24/7. No
overclocking has ever been done. Does anyone else thing this thing is
dying? I'm getting ready to pull the trigger on a replacement but
really don't want to.

Thanks for the input.
