What is wrong with my graphics?

[ViperGTI]

I've been experiencing this for a while now. Sometimes a restart sorts the issue out, sometimes not. I've tried turning SLI on and off, installed the latest graphics drivers. Does anyone have a clue as what could be causing this? It happens in one form or another in almost all games.

In Witcher 2, the images are not smooth and becomes "pixelated" and the issue as in Skyrim below appears as well. See these two screen prints. All graphics settings are set to maximum except for the "Uber" setting in Witcher 2.

In Skyrim and a lot of other games, there are "phantom lines" that appear. I'm not exactly sure how to describe it (which is why I don't know how to google it). I couldn't fully reproduce the issue just now so the image below is a small sample, but it can get so bad that you cannot make out anything on the screen. There is usually a lot of flickering of objects involved and the lines are usually part of object or people that can be moved.

I'm running 2 MSI nVidia Geforce N560GTX Twin Frozr II in SLI.
I've uploaded the full sized images at the links above which is why they're not embedded into the message.

Any ideas on how to fix?

What PSU are you using? Can your PSU handle 2 cards? If yes, then :

Change your SLI ribbon. I had WEIRD issues with a faulty Crossfire bridge about 2 weeks ago. Changed bridge and my problems disappeared.

PSU is fine. Couger 750W which is enough for my setup according to various PSU calculators.

Ok, so now I've changed the bridge cable, completely uninstalled the drivers and installed them again and now everything's gone to hell.

I have 3 monitors connected to my pc, one which is always disabled in my gaming OS due to SLI. Now as soon as I enable SLI now, my primary desktop disappears and my primary monitor kinda mirrors my secondary desktop. It is quite weird because I can move the cursor between the two screens but I can only click on the secondary monitor. So although my primary desktop is enabled, it is not visible so if I want to open the Screen Resolution window, I have to right-click on my secondary desktop, click Screen Resolution, then press Alt+Space, down arrow, M and then hold down the right arrow so that the window is moved over to my secondary desktop.
Now, if I try to change my settings to switch only to one monitor or to make my second screen my primary desktop so that I can at least see the Start menu or if I try to disable SLI again in nVidia control panel, then all my monitors turn off and I have to reset my computer.

After a couple of restarts and switching between safe mode, uninstalling the drivers again and reinstalling, I've now managed to get Windows up and running again with SLI disabled.
I'll create a restore point in my primary OS later and try turning SLI on in there to see if the problem occurs there as well. If it does, I suppose the issue is hardware related and then I'm clueless... otherwise a clean Windows installation should fix it.

If you're saying what I think you're saying, I'm pretty sure that is just how the Witcher 2 graphics look. Then again, I'm also running GTX560Ti's in SLI, but I assumed that was just how the shading worked. No idea about Skyrim though that looks weird.

Ok, got SLI working again. The new bridge cable that I put in caused the weird problems when SLI is enabled.
Will see if the other issues persist. Hopefully the clean install of the graphics drivers fixed that.

Could be, but it looks pretty bad. I haven't played it in a while so can't remember how smooth the graphics was. It could also just be the latest patch that is causing this. I'm thinking of maybe downloading the full game from scratch with the patches pre-included.
