I am having the exact same problem as you and was about to open a discussion when i saw yours.
The problem originated when I was playing a game, namely Diablo 3 when it suddenly crashed and the screen got all ''tored'' like you put it. It got so bad that i couldn't even open apps anymore. I reinstalled windows again everything went ok till i updated to the newest driver. I updated to windows 8.1 in hopes that the problem would be solved but it persisted.
Haven't come up with a solution yet. The only thing i've come up with out of frustration is to disable the 4600 driver, which, works but it's only a 'band-aid' solution really.
I'm using a Sager NP8250
I am also noticing the same problem as above. Had to refresh the desktop to remove the tores.
Also when i am browsing the internet, if i scroll down some pages i get tearing across my monitor.
Lazha & Oh_dear,, what type of display are you using?
Can anyone change the memory modules in their system to a different brand and test the results?
Samsung sc450 s24c450bw/mw
I'm using AOC I2757FH, I got a pair of these. (same results on both monitors)
I'm currently using Adata 16gig 2400 ram, also tried 4gigs of Corsair Dominator 1600 and tried 8gigs of Patriot 1600 all with the same results.
Tried my old AMD HD 5850 and no problems with display and currently using GeForce GTX 780 Ti and no problems either.
@ Lazha,, thanks for the information. Are you currently using the latest Intel HD Graphics driver available here:
Yes I am using the latest drivers. I've also tried beta and it had the same result.
I forgot to add that this happened when i started using a second screen, a Sony Bravia screen, for the first time. When the problem happened it was not connected tho.
Yes the new Drivers don't work for me either. Actually it has gotten worse. i reinstalled Windows 8, installed an early version of the driver, the one that's in the Driver DVD that comes with your Computer/Laptop and the same thing happened. I'm worried that the Graphics Card got damaged/it's a hardware problem.
@ mmetcalf,, Thanks for the additional info. If run just a single display, doe the issue still occur? What type of cable are you using for the second display? Do you have access to a different cable you could try?
1. Yes, (should've bee more specific) It happens on my Laptop Screen now.
2. I'm using an HDMI cable. It's from Chinese Brand called WEI. It was a gift from a friend who bought it in South America (if that's any help).
3. Not at the moment but i will try for sure. But since now the problem is located at my primary screen i can't really do much since i, for example, get black screens when i try to open basic Windows features such as Control Panel. I don't have any Intel driver installed at the moment since i'm having this issue. I'll try and see what happens
