 Posted: Tue, 4th Jan 2011 05:45 Post subject: Graphic Artifacts |
|
 |
It started a few hours ago, I first noticed when scrolling on websites, but it's happening everywhere on the screen (like moving windows, or even while writing this text, it still happens a bit). The colors get all fucked up, it's like a classic artifact, only happens where something is moving on the image.
Is my gpu dying? I didn't try any games yet, but will do tomorrow (and yesterday company of heroes was fine). The card is an ATI 8470, it's not too old, I was hoping it would hold for at least another year.
(The problem is not OS related, it's happening both in windows and linux, and it seems to be getting worse)

what are the temps on idle when browsing with artifacts?
@nalo : Ive seen rainbow patterns on my vlc player etc when trying to move a video along some timeline a bit but I think thats more an encoding issue with the vid maybe? dunno ive always seen that with some clips or films, I go drag it back if i was called away or something and it takes time to pick up again and for the image to settle..
good quality downloads of films though just have a tiny pause before playing again..

Didn't bother checking the temps, don't even know if I have any software for that right now (on Linux). Will see, but I never had a temp problem before, and it's not that hot here lately (not cold either).
It might be too much dust though... it's been over a year since I last opened the case.
And it has nothing to do with videos in my case, I'm not playing anything and this happened on windows 7 too... No lack of memory either.

Ok the idle temp is 54C. Nothing wrong, I guess, but the artifacts are getting worse...

Do you have artifacts during POST? If you've got them there as well, then it'll be the graphics card.
Otherwise you'll have to do some more testing to find out where it's coming from exactly, run memtest yet?

Wow, so how does it feel to have a card from the future?

No, it's a secret card from the R200 series

Nah, my idle is 55-58. Can go all the way up to 65 during the warmer seasons. This shouldn't kill the card on its own (although I only had my current GPU for just over a year).
If you have already damaged the card at some point by overheating, then I don't think your current low temperatures really matter since the damage is done.

Isn't it supposed to slow down (or something) when it reaches dangerous temps?
Also, I didn't notice any artifacts during post, only after the OS (win7 or linux) graphic mode starts.

The memtest shows nothing. Will try a different screen/cable later.

Make sure it's firmly in its PCI-E slot, and you could try underclocking it a bit. If the card is at fault, underclocking should get rid of the artifacts

I never overclocked it, and I didn't move the pc either... But I'll try reseating it.

Not suggesting you ever overclocked it, but if underclocking (below stock speeds) gets rid of the artifacts then you can already be sure it's the videocard

Auto is shit for ati, I have found its very dangerous to leave it auto select lol, first thing i do with ati cat installs is enable the o/c and fan control, check temps and set fan speed somewhere usually between 45 and 65 depending on the general room temps at the time.
Ive watched auto control for a while.. U might notice not sure u do maybe you dont get this, but when you first boot into windows the fan does not engage till the applicaiton ( catalyst panel ) etc is all loaded up into taskmanager.
and at times ive seen it not even do that until you manually open the panel and check.. first thing i do actually is that every boot..
To me leaving an ati driver set to control its temps is beyond nuts  , set the fan manually and leave it.. job done.. regarding the temp at idle on 100% fan speed, that does not make any real clue to whats going on cause if my card is at 39c idle and i put it to 100% from 65 uc an bet it wont go much lower than its already idle state.. I still think your idle is way too high..
Im thinking then its possible the auto control you leave it on ( that is not turning manual control on ) has prob in past with bad driver sets, fucked your card up after a game session and has not done its job with the monitoring due to some dodgy profile shit somewhere..,
the 4870's as well act alot different with the catalyst control auto/manual ive noticed comapred to the more recent 5 series cards.

The fan does work from the start. The difference is that when you log into windows, the catalyst control settings kick in. Since you set your fans to 60% you can actually hear them quite well. Until you log in, the fan should be working, just at a lower rate since the card is cold, making it quiet.
I have the opposite situation. By default, the fan stays at about 25% with Catalyst settings enabled, making it pretty quiet, but this makes the temps go up to 55-58 as I have said. Now when I log off, the non-catalyst settings kick in, increasing the fan speed to drop the temperature (the firmware temp thresholds must be different), so the fan makes it's presence known quite audibly during restarts
At least I think that you have a similar situation. The auto options are not by themselves dangerous - they are optimised for less noise on idle. But as soon as the temps go high enough, the fan will speed up.

If you're talking to me, the artifacts don't show on screenshots (I tried both in windows and linux).

That's possible. I remember I used to leave it at 50 or 60 manually when the card was new, then I had to format and didn't even bother installing CCC again, just the drivers. Now its running on manual, but I guess the card is fucked already... I'll try a different screen now.

Damn, I think it's the screen. The problem disappeared on another screen (an old 19" flat panel). I guess it must be this damn LG W2353V then? I tried different resolution and refresh rates with no luck. This POS has only one year warranty, and I bought it 15 months ago...

ah thats good then really, well not i guess, the card and screen can be of sim price these days
well lets hope its that then, id prefer a naff screen to a naff card, do some research on the monitor see if its just components dropping out as you can replace them yourself sometimes like I did with the capacitors on the samsung i got, good as new now.

The problem is completely gone today (and I didn't do anything else to fix it). Maybe time to sell this screen and buy that IPS panel I wanted...
