Ok, so the problem isn't exactly tearing, but sometimes images remain visible.
For example when I scroll down a web page some parts of the screen remain with a still image. It's the same when I select icons on the desktop. It's as if a layer of the screen crashes and remains static until I mouse over it or change the image again. I tried to make a screenshot, but the error doesn't appear on the screenshot image (weird).
This happened right after I installed my videocard (ZOTAC GTX 660 ti AMP!).
I tried different driver editions (304, 305, 306.2, 306.23 - latest), tried wiping the drivers cleans with Cleaner, tried all the V-Sync options (adaptive, always on, adaptive - lower framerate).
The problem exist only when browsing in Chrome (i don't seem to have the same problem in Internet explorer).
I disabled the Nvidia 3D plug in for Chrome and tried all sorts of option setups (both global and for chrome only).
I have a second monitor through DVI+ converted to VGA and my primary monitor is DVI-. I tried unplugging the secondary monitor but that didn't help.
60hz, the only available option. I tried tempering with the pre-buffered frames (i'm not really sure if it was supposed to help). But the problem also occurs on my desktop when I move icons. Generally I use my pc for browsing and gaming. And the picture crashes at websited without flash, like Guildwars2's header (that one crashes all the time, I use it as a tester).
8GB Corsair 1600mhz, no programs apart from the casual bloatware. Like I said, I associate it with the video card and I am worried it could be a hardware issue. I bought the video card rather cheap for the OC performance it has. I tried switching my monitor to my integrated motherboard DVI slot but it didn't start up. Could the issue be with the video card's DVI connection?
CPU is around 40/45 celsius while gaming (Guild wars 2 max details.) Motherboard is 30/35. I don't know how to get a reading on the GPU. But it seems like a bug, rather than overload. I thought the new nVidia drivers would fix that, but they didn't.
The problem disappears when the card is removed. I tried the stock drivers again, that came with the CD. Problem still persists. I'm running the latest flash and java, although even when I disable Flash, nothing improves. Another annoying thing is that the onboard intel hd 3000 is completely disabled when I put the card in, so basically I can't use Lucid Virtu and I can't use my motherboard's VGA connector. Is that normal?
Btw I checked that 'speccy' tool, it doesn't get a reading on the GPU, I guess it doesn't have a thermometer.
