I've an Asus laptop with a 745M and an i7-4500U.

I play League mostly. Whenever I play I get very bad screen tears. Not just small glitches, but HUGE masses of the screen getting cut up, showing black underneath, all tearing at maybe 10 fps rate. The in-game fps mark shows no change.

I then used the 745M to load up Rome TW2, ASC III and even Warcraft III and Crysis. Same tearing problem, even when I'm only in the menu, not even in game yet.

What's weird is that after this, I unplugged the machine for a while, letting the battery drain down to below 90%. Turned it on again, and voila everything WORKS PERFECTLY without tearing. When the machine gets fully charged, the tearing comes back again, slightly at first then developing worse and worse.

I changed to the integrated graphics for League, and after a week or two of normal behavior, the same tearing problem is here again, albeit with slightly smaller tears at lower frequencies.

Now, the problem is even occurring outside of gaming. At times, the screen would have a straight line or two cut up horizontally across my screen, or the whole screen would go dark for .5 or less of a second.

I was at a friend's house and plugged my laptop in one of his monitors. Loaded up League, everything on the monitor runs FINE, no tear whatsoever while only the laptop screen tears. Tried this with the rest of the games, all runs fine.

I've tried the usual route, uninstall nVidia drivers, install new ones, uninstalled, install older ones, etc. Didn't work at all.

Can anyone tell me what's going on? The tearing problem at first is very subtle, but then gets worse and worse substantially. I called Asus support, they said they'll look at it for 5-7 days and decide to give me a replacement or just return it back, "fixed". But the problem didn't show up for me after the first week. Sending in my laptop, I'm wiping everything letting it start just like out of the box, so I'm afraid Asus won't see anything wrong and keep sending me back this defective unit.

Can anyone give me a solution? Either fixing my laptop or just hasten Asus support to go straight for a replacement.

Thank you!!!
