blue vertical lines

[Harry]

I have narrow blue vertical lines that appear on monitor whenever that colour
is displayed; also, all white backgrounds in any program have wide yellow
vertical columns that do not print. I have New monitor, XP3, up to date
drivers & trend micro anti virus.
Any ideas on how to get rid of them?

That is either a hardware problem or a driver problem, so you should ask
in a hardware or operating system related newsgroup, not in a software
development newsgroup.
