I did as you suggested and updated the graphics card driver. This did not help. I also tried lower resolution. The problem is that there are big splotches and lines of purple/red pixels (even when i lower the resolution), and these areas of pixilation change according to whatever appears on the screen, so for example, if there is a photo of mountains, there will be pixilation on parts of the mountains, and if i am viewing some graphics, there will be pixilation along the graphics. It's not just a couple of bad pixels. It began this evening a little after downloading a photo from a disc that my sister had send me, so i assumed it's a virus, but a complete virus scan didn't turn up anything. Any other suggestions will be most welcome. Many thanks.

Re: Thank you for your suggestions
Hi Shaidan ... try going into the system settings and advanced then visual effects under performance ... put it on custom then disable (remove checks) beside everything ... also many graphic cards have fans on the graphic processor these days ... you can take a look at that and make sure it is clean and performing ok ...

Intel Integrated Graphics will give decent resolution performance but is not an optimal graphics.
Ensure you are using the optimal resolution 1366x768 pixels. Using a lower resolution will give you a unsatisfactory display.
If you still don't like the graphics, you may need to add an expansion video card.
I BELIEVE ITS THE DRIVERS.UNINSTALL ALL VIDEO DRIVERS AND INSTALL LATEST DRIVER FROM GRAPHICS CARD WEB SITE.GO INTO THE BIOS AND TURN OFF ONBOARD GRAPHICS.SHOULD BE FINE..ALSO MAKE SURE YOU HAVE CORRECT DRIVERS FOR YOUR OS.ALSO UPDATE DIRECTX.RECHECK GRAPHICS CARD CONFIG AFTER NEW INSTALL.RICHARDM69
its not in the driver..
its how the resolution of ur device to capture ur pictures..
and its in the pixels too..
other one is ur video card..
coz lower memory video card,,the lower the resolution of ur pix..
It could be the monitor but from you earlier descriptions it seemed to be related to the graphics card ... can you test your monitor on another system ... also you can reset the monitor settings using the controls on the monitor its self... the suggestion about the graphics card fan requires you to look inside the computer system ...
are you sure you have connected a graphics card. If so you dont need any driver because the graphics card depending on the model has already the necessary driver included just like when you first bought your motherboard.
Now, if your're only using the onboard graphics( that is the graphics card of the motherboard itself), you have to check whether the graphics supports resolution higher than 640x800. On board graphics, as far as i know contains only the necessary that will output on your screen, it means the resolution should not go much higher. But, you still have to check.
For assurance and for the best picture you wanted to have(probably your'e playing high resoulution games), I suggest that you buy the necessary graphics card that is supported by the games. Example of such brand is inno3d series.
