Hello everyone,i have a problem that i am hoping your expertise may be able to help with.About a year ago i bought a xps 710 from dell.When i received it and started it up i noticed some strange banding around the light source in the top left corner of the windows welcome screen .It is almost impossible to describe to people so im including an image if you click it you can see the problem much better.
When im gaming the textures are all blotchy smoke is chunky .Now we have been able to rule out the vid card because i tried another of the same cards and was still there .Its not the drivers for the card either as it is more prevelent with no drivers installed and like i said it came to me like this so its not a virus or anything if anyone anywhere has ever seen anything like this before id really appreciate a hand thank-you very much for your time
