Black double curser lines on screen

Check out attached any one ever have this happen the all all black not white as in the snip and the blink of and on and i can mouse a square around then and make then go away but they come back.

Try another monitor...then try turning off every thing on the same electrical circuit....

Could it be artifacts or not now today so far they are gone.

They were gone till I moved the mouse and opened something up like my user name folder. well will have to try another monitor tried another cable so far and updated the CCC.

could be electrical interference.....turn off everything electrical near the computer and see if the problem goes away

Thanks tried that and still have the black lines they are like in a perfect grid pattern at times ordered a new vapor x HD6770 to see if it is the video card after all someone said it is the Vram I think just ran Dirt and it had 258 errors or whatever they were called at 30fps. I tried another monitor also same thing lines.

I like to try the no money solutions before suggesting a new card....nothing worse than having a problem follow you...here is some examples of video card problems..

Diagnose video card problems by comparing with example corrupted screens

Well today they are gone i use the Media center to watch tv or listen to the music channel all night and it was losing sound all night or at least when i would wake up but the lines right now are gone and the Malicious full software Microsoft scan is done which might have been causing the other issues, since it was running all night, with no problems found, and i have checked and did just about everything on the list from the link that was just posted thanks .

Well I surfed for awhile looking at the video card link and the card was at 44c now its at 35c and the black columns of lines are back only thing different is i turned of the Media center and just had Firefox and my money file open. Ha well we will see when the new card comes if the card is the issue , i have the identical card in my media center pc downstairs but two much troble to take it out to try the other card . The black lines are on this post as i am typing the text. 6 minus signs to be exact.

Play around with open programs...see if anything changes....
