Flickering monitor

[roger]

Hi all,
my monitor has started to flicker quite badly, I don't know if this is
the monitor itself or the graphics card. It started suddenly and sometimes
it's bearable sometimes not. Is there any way in which I can tell which is
at fault? I used to have speakers nearby and the magnetic interference would
sometimes affect the monitor but I have now removed them but still no joy.
Any suggestions?

Abit kr7a-raid
512k RAM
AthlonXP1600+
Soundblaster Audigy
ATI Radeon 32mbDDR

I did read that the memory positions on the mobo could have some adverse
affects, could this be one?

TIA

Roger

My monitor sometimes flickers or shimmers after changing resolution, usually
after a game. I can only assume that it failed to properly lock onto the new
signal properly because a quick change of the resolution would correct the
problem.

Does the monitor flicker in different resolutions and refresh rates?

That reminds me of bad guns.

How old is the monitor? If it's older then possibly the CRT is going.
Usually video cards aren't the culprit when the monitor that's to flicker,
it's usually a hardware issue within the monitor itself.

Take your monitor over to a friends house or a local retailer and ask them
to hook it up to one of their demo units to see if it still flickers. If it
does then the monitor is definitely gonna need replacing

First step would be to try the monitor on a different computer and see
if the problem still exists. If it doesn't, than the video card would
be the culprit.

Have you checked the refresh rate? If you're using WinXP, it has a bad habit of
reverting to 60Hz at the slightest provocation.

Hi Jerry,

How 'goes' the "Battle" ???

First step would be to try the monitor on a different computer and see
if the problem still exists. If it doesn't, than the video card would
be the culprit.

How is your monitor described in Display properties? If it is Default or
default PNP then you have not installed the monitors "driver" (INF) file.
GOTO the manufactures web site and locate/install it. This will ASSURE you
have the correct refresh rate for your resolution.

Silly old geezer you are. Why would I flick mine if i'm atop a sheepie?

I get flicker but that is caused by my halogen desktop light.

Hey Roger,

A question for you. Does the monitor start to flicker right away as you
start the machine up, or does some time passes (no matter how little)
before it starts doing that. If it's the latter that the cause could be
the video card proccessor/memory is getting too hot.

I still recommend that you try the monitor on a different machine first,
as that would definitely identify the faulty equipment.

 

[roger]

Well sometimes as soon as I start the PC it can be pretty violent, sometimes
it seems to stop and every now and then just a reminder that it will
flicker. If the graphics card is getting hot what should I do? It has it's
own fan.

 

[Jerry Polyak]

The reason I asked is this. I had an older TNT2 that did something
similar (the display would deteriorate after some use). The cause was a
bad fan on the video card. I never fixed it, since it didn't seem worth
the effort to safe a $15 card.

But what you can try if it is indeed getting hot, is remove the fan
(make sure the fan is working), apply some thermal compound to the video
proccessor and reinstall the fan (much like you would do to the CPU).
You might also consider installing some heat sinks on the video ram, as
those can cause problems when overheated also. Check out
www.2cooltech.com for some ideas. Or replace the card.

I would still strongly recommend that you eliminate the monitor as the
cause first (id you havn't already done so). Might save you some time
troubleshooting

Well thanks to all you guys for your help, I have actually just bought
myself a new TFT screen and so far (touch wood) no problems. The old screen
has just been donated to a family member so it will be interesting to see
what happens. Very informative replies from all of you. Thanks once again.

also the driver (INF) should be loaded, so windows knows what the the
correct resolutions and refresh rates would be for your monitor.
