I’m really lost as to what this could be, its been bugging me for a long time now and I cant seem to find a reason/fix for it!

Ok, so when I’m working within Photoshop these odd pixels/artifacts/lines or whatever you might call them just appear randomly. Take a look here and you will see what I mean exactly (Note: Image was made with Paint so its poor but you’ll see the problem)

Quite a large image : <http://img115.imageshack.us/img115/1169/problemsai1.jpg>

On the larger/back image you will see tiny little blocks/marks which form when I open the .PSD and these will still be present when i go save it as .JPG and the only way i can remove them is by painting over them with the brush tool. The problem with this is that more appear elsewhere, so there isnt much i can do!

Now focus on the smaller second image, the problem i had/have here is that when i apply stroke to a layer these dots form around the layer randomly. Each time i adjust the stroke width they draw elsewhere like some random generator of sorts! Once the draw stroke is more than 30px it seems to go away. But i believe ive fixed this problem by disabling my SLi, which seems to have removed this problem but my first problem still persists!

Ive never had this problem before only since ive had this SLi so i guess this is probably the issue? Ive gone through the Nvidia tool to change all the millions of settings, but nothing changed.

Ok well thats about it, any ideas/advice/input would be cool, ive already searched the net high and low and cant seem to find any answer.

Thanks again!

Make sure you have the latest video drivers. When a program throws junk up on screen it is 99% of the time because of faulty video card drivers and/or video card firmware.

When you paint over a bad pixel like that, you are also requesting a refresh of the pixel on the monitor, so it may well be that your action didn’t actually correct the problem so much as the refresh itself did. So, the next time you observe this behavior, try refreshing your display a few times and see if those artifacts shift around in your image. If they do, you will know the problem is not in the image itself but only in the display rendering, which does indeed suggest a video driver conflict.

Something you might try, although I’m not sure it would make any difference, is reduce or disable the hardware acceleration (Display Properties > Settings > Advanced > Troubleshooting) of your video card and see what happens.

Ive given it a shot and it stills giving me trouble, ive tried reducing hardware acceleration and that didnt seem to have any effect.As for the latest drivers i have those but this could also be a problem, as with everything latest isnt always the greatest. So perhaps ill go back a few revisions to see if it fixes anything.

What i really need to try and do is replicate these problems elsewhere to see if its photoshop or if its actually a little more serious. I do play some games and they’re fairly GPU intensive and I havent noticed anything in any of those. I guess its safe to say the problem rests with my SLi setup but im not sure what exactly it could be? The cards are both less then 3 months old, and are in stock form with no Overclock and good tempratures all round. This doesnt mean that they’re not dying or dead, but ive not had any problems elsewhere so it’d be stupid for me to rip them apart purely because im having issues with photoshop.

O well, if this goes any further im going to have find a new tool to work with! I hear Gimp is pretty powerful?

Thanks again.

Did refreshing the screen at least cause the artifacts to shift position? Again, remember how if that is the case, then at least you can be reasonably certain your image file itself is not degraded.

Another thing to consider is whether you’re using native nVidia drivers or those provided by the card manufacturer. While the latter are often just the nVidia OEM drivers, there might be a few tweaks unique to that vendor’s design.

Are you absolutely sure that all internal data connections are seated properly? Wouldn’t hurt to open up your computer, disconnect and reconnect them firmly, just to make sure. Do the same with any cards and RAM modules. Do the same with any external connections…monitor, network, local peripheral hard drives.

No the artifacts didnt shift when I refreshed, they seem to only shift when i try to brush over them. And they’re always in the same position once i start a file up. I can completly draw over the lot of them, but it takes a while and they’re back again the next time i add a layer or resize something. As for drivers, i am using the regular nVidia set from their website, I am running two XFX 6800 GT Ultra’s and they perform ok anywhere else.

Phos:
Yeah im positive all connections are seated snug and in their correct place, i built the box not long ago and its all working fine. If anything was unplugged/not connected im sure it would inform me.

Have your tried changing the cables to see if that’s where the problem is?

And do try to reseat all your connectors.

That does sound odd that the artifacts are in the same position after a layer or resizing. Never seen anything like that myself. I’m currently running an XFX 7600GT card on a PC I recently built, but it’s only a single card, and I have never such problems. You may be right that SLi is somehow the culprit. Wish I had other suggestions but I don’t. For what it’s worth, I’m running ForceWare version 91.47.

This from a previous thread on the subject:

That sounds a lot like bad RAM or a bad disk.

If the bad lines disappear when you zoom in and out, then it could also be your video card.

But does the OP mean the same position on the image or the same position on the monitor?
