Windows 7: Screen blinks while in grey and white combination backgrounds

Hello! Since yesterday I've noticed that whenever I access a page with grey and white colors (Hotmail, Messenger, Latest news, Sport, Music, Movies, Money and Cars from MSN UK this one is the only one so far) some lines appear and they blink, this does not happen in white or black backgrounds, I've tried removing video drivers (when these were uninstalled there were no lines, but when I installed them back again the lines came back too ), doing a flash player clean install and restarted in safe mode (when in safe mode the lines did not appear) , I don't know what to do ; My GPU is a RADEON HD 6850, and I've tried with an old driver and with a new one but no ; I don't have any other PCs so I cannot try the monitor in another one unfortunately



Please help me I don't want to format

Your card may be overheating, check for proper airflow in your case and remove any dust blocking fans
Test your graphics card NVIDIA/AMD Video Card - Test with OCCT

Here, the GPU is clean, checked myself and I blew it so it's clean , I did a 10 minute stress test with OCCT here are the results :



















PS: I have just formatted my PC (before taking those pics) and the problem persists


Just tell me if you need more information or tests

Test results look fine, could you provide a screenshot of the display problem.

The lines didn't appear in the photo I took, so I made this one from my PC showing where the lines appear




I've tried other pages with grey and white combination backgrounds but it only happens on this one, the lines in the beginning are hard to spot but after a min or so they become clearer and more annoying , I know it's not much but this has never happened to me before, and since I've formatted and the problem still happens

Hi.

The easy step first.

In your default internet browser,disable non necessary addons.

Also try with any other internet browser.

I'm using Firefox, I disabled all non necessary addons but It keeps happening, I've tried with IE9 as well and it happens too, even if I take a pic and open it in paint those weird lines will appear too, unless I zoom in or out , Which is really odd is that sometimes the lines appear and sometimes they don't

You said the problem does not occur when the driver is uninstalled. Have you tried doing a full uninstall using Driver Sweeper and then re-installing with the latest driver? To uninstall with Driver Sweeper:
1. Download and install Driver Sweeper
2. Go into device manager

• a. Click Start Menu
  b. Click Control Panel
  c. Click Hardware and Sound
  d. Click Device Manager

3. Expand (click the +) Display adapters
4. Right click your graphics/display card
5. Click Uninstall
6. Put a tick in Delete the driver software for this device
7. Click OK
8. Restart your computer
9. Start in Safe Mode
10. Start Driver Sweeper
11. Put a tick in AMD - Display
12. Run Analyze
13. Run Clean for all drivers.
14. Restart your computer
15. Install the latest display drivers.

Let me know if you have already done the above steps.

If you have not done them already, let me know if these steps fix your problem. I'm guessing when you uninstalled before, some of the driver software was not fully uninstalled, hence why re-installing the driver software did not fix the problem.

Edit: if the above does not work, try uninstalling all AMD components through control panel add/remove programs (AMD install Manager, AMD Catalyst Control Center, AMD Drivers, etc.). Then re-install those components.

Hello! Thanks for your answer
I've tried it and it did not work , also I've formatted and it keeps happening as I stated before I have the latest GPU drivers.

What happens if you run at a lower resolution? I seem to remember having similar issues a long time ago on an old GPU card, and I think I solved the problem by changing my resolution or monitor frequency. I cannot recall which fixed it at this time as it was probably five years ago when it happened.
