System windows xp.


I have just recently got a problem where I have developed vertical blue and pale pink lines in all my media players in video and stream mode. This happens with my own film files and streams etc. Winamp, wmp, nero, vlc all have the problem. However msn, youtube and some streaming sites are fine. I also have in recent weeks had blue lines in start up.
But all is clear of lines once operating system is running and front icon page is open!!
I guess this could be a video driver issue???
Look forward to some help.
Thanks in advance!!!!!!

Sorted it. Think maybe my C-Cleaner made a tweak in registry fix mode!! Any how the video overlay boxes had somehow got ticked in all my media players. ??? very strange!!!Any other comments regarding this issue would still be greatly appreciated!!

Thanks
