Hello , my problem is that my monitor started to have many green pixels , especially on black screens . I had that problem before , but it persisted like 10 seconds , but now it seems not to stop . I tried replugging the cables and all that stuff , reinstalled drivers , changed refresh rate , checked if video card is alright . Do you have any idea why this happened ?

is the green flickering consistent (always in the same spot, or at the same time, or running the same app? anything that is teh same when it occurs). Have there been any hardware changes to the computer? Have there been any changes to the devices around the computer or where the computer wires are running?

Its all over the screen . When the computer boots up and the screen is black , its very visible , sometimes in lines , but now they are running randomly all over the place . I haven't changed my computer's hardware in a long time . I have only a pair of headphones that i'm using right now and a speaker that isn't plugged in.

Did you uninstall the Nvidia drivers before installing the new drivers?

 

Did you download the drivers from the Nvidia website?

 

What is the make and model of this computer?

 

If this is a custom build please do the following.

 

Please download and install Speccy to provide us with information about your computer.  When  FileHippo opens, click on Download latest version in the upper right pane.
 
When Speccy opens you will see a screen similar to the one below.

Click on File which is outlined in red in the screen above, and then click on Publish Snapshot.
 
The following screen will appear, click on Yes.

ok thank you.  First lets check for outside interference.  If the video cable is next to any other cables please attempt to move it away from those cables to see if the flickering stops.  If it is caused by outside interference you may have multiple cables that you need to pull the video cable away from in order to solve the problem.  If you cannot avoid a cable, try to make it run perpendicular  to the video cable instead of running along side it.

 

I understand that some setup's will not allow this to stay that way, but currently lets try this despite the problems in asthetics or space restrictions.  Those can be addressed after the problem is resolved.

You need to uninstall the Nvidia drivers first, then install the new drivers.  

 

Uninstalling NVIDIA Drivers
 
Before installing new NVIDA drivers you must first uninstall the old drivers.  It is very important that the Graphics Driver be the last driver to be uninstalled.  If this is not done you will find yourself repeating the process.
 
Before uninstalling the drivers you should download the new drivers from the NVIDA website.  As you can see in the image below there are two means of finding the correct drivers.  Option 1: is the manual method, Option 2: is a automated scan which will find the correct drivers.  
 
nvidiadownload_zps19003119.png
 
Don't open the drivers until after all of the drivers have been uninstalled and the computer has been restarted.
 
In the Start menu click on Control Panel, when it opens click on Programs and Features and wait until it is populized.
 
The programs are alphabetized, scroll down to the Ns where you will find the list of NVIDIA drivers similar to the one in the image below.
 
Nvidia_zps01e691da.png
 
Important: Users of older motherboards with a Nvidia Chipset may find a ChipsetDriver listed, these are unreleated to the Display Drivers. If you uninstall a NVIDIA Chipset drivers, your system could become non functional and require a installation of the operating system.
 
Remove these drivers one at a time leaving the Graphics Driver the last to be uninstalled
 
Place the mouse pointer over the driver you want to uninstall, this will highlight the choice.  Right click on the driver, a window will open with the word Uninstall, click on this to uninstall the driver.  After the driver is removed from the list go on to the next one. 
 
Note:  If while uninstalling the Nvidia Drivers the system asks for a RESTART after uninstalling a driver and it wont let you proceed when choosing "restart later", then its OK go ahead and restart and pick up in the Control Panel under Programs and Features where you left off.
  
Now that you are left only with Graphics Driver, uninstall it.   
  
The system will ask for a RESTART, you should now do so.
 
Windows has as native graphics driver which will make it possible to continue with the installation of the new NVIDIA drivers.  You should install the new drivers now.

 

Windows has a native graphics driver which will take the place of the Nvidia drivers while you install the new ones, so you will still be able to use the computer.


Family and loved ones will always be a priority in my daily life.  You never know when one will leave you.
