Lines coming out in the screen

There are couple of ways to isolate the problem to be more specific. 1st. try to change the monitor, if the same thing happen again then properly you need to change your display card. But there are some types of display cards will be having this kind of problem whenever you shutdown and restart your NT (this is common, as long as you still able to use it). I hope this can help you.

I'v experienced with a similar problem.
In my case there was a problem with the adapter's memory chips.
I recommend checking your adapter in a lower resolution and with fewer colors.

Check the connector to make sure it is secure. Next try moving the monitor...you'd be surprised how rf energy can effect your display. There may be a radio nearby that is doing it or even a fax. Failing that, try a different monitor. Then the graphic card. What graphic card are you using and what resolution/refresh rate do you have it set at?
