I've had my 3505 for a couple of days and I am already having problems with the screen. There are white horizontal lines on the black background of title screen and then there are numerous reddish vertical lines when it finally got to XP screen. However, after the computer is warmed up a bit, I don't have the problem. Before I go back to Circuit City and have them look at it, can someone advise what I can do to remedy the situation. Should I wait and give it a few days to let it "break in" or do you think it will be a persistent problem? Would reinstalling the video drivers do anything? All there possible loose wires to the display unit? Thank you for anyone who can help.
