Need help please strange artifact issue Nvidia 9800M GTS

Hello guyz, i just register here because i need help with a very weird display issue with my Gateway FX P7805u Laptop (9800m GTS) i have searched every where for the issue but couldn't find any symptoms yet, the issue started a few months ago when playing call of duty black ops 2 and since then it has only increased, the symptoms appears only in areas where dark color is dominant. strange vertical lines appear over the screen which is similar to pixel distortion or screen tearing, its not a driver issue as i have tried over 20 different drivers (after cleaning with driver sweeper) these lines are produced over gateway bios logo(dark area) and windows startup logo(black background) as well and they start to appear after 10-15 minutes of gaming but disappear if i turn on laptop for half hour or background color is white or light colors. i have taken some pictures from my cellphone camera they are not very clear but will tell you exactly what is going on.

1) Website of omega forceware driver, note the black background and lot of pixel distortion, but no distortion in the menubar of firefox and taskbar (light colors)





2) Pixel distortion in windows media player (gives clear idea about how the distortion looks like).





3) Picture taken at same time of above pictures but background is white/light and whole distortion disappears.




I have been monitoring temperatures of both cpu and gpu, gpu idles around 45c-52c and uptill 68c-82c during gaming/heavy usage, i usually increase brightness of games and this doesn't happen/minimize during gameplay due to brightness. there seems to be no problem with gpu, and it runs absolutely fine but these lines appear over dark colored areas. Once i turn of laptop for some time they disappear and don't appear again till game play. If this is gpu or gpu ram fault wouldnt this be appearing even if the background is light/white??? Please help me.

 

Hallo Buddy.. i usually just knock the multimedia button above the keyboard area..
or you can open your notebook, unplug and plug again the lcd connector on the mobo..

you wont believe how much happy im right now, after 2-3 knocks on the multimedia bar the display problem corrected, when i will give laptop for service... i will ask them to reconnect lcd connector as well. this problem was making me crazy since months.. even one repair shop asked me to reball gpu to fix it. but now my laptop is back to life, thank you so much, below is picture of omega drivers website now

 

Hahahaha..
My friend, I am soo happy that I could help you out..
when first time I encounter the problem I search help from this forum but at first they ask me to change the LCD to mobo cable.
I order an LCD cable from ebay ship to me, it took about 1 month to arrive from USA to Indonesia (south east Asia), as I play games the problem appear again after playing games (CPU/GPU get extreme heat).
So I accidently find the old Thread shows how to fix this problem.
Actually its not really a big deal as you need only to re-plug the lcd connector cable at about under your keyboard.

If you want you can try to open it your self.

The funny thing is, i never open this forums for many months or maybe almost 2 years now, and all of a sudden i read your post and able to help you right away... hahahaha..
