Hi I have a problem.  My computer keeps displaying pink and green verticle lines accross the page.  They do at times go away but always come back after a few days.  There are currently 5 verticle lines going down the page.  They have a shape to the line block.  Kind of a white pattern through the pink lines and the green lines are made of the pattern with the gap showing the screen behind it.  The lines are around 6 cm wide. 

When they first show up the entire screen is filled with the pattern in pink and white and then it turns into the pink and green block lines.  When you turn the machine on  and off they first show up again as red and white lines, in the same pattern as the pink and green I described earlier..  I am using windows 7 and have an acer aspire z computer.  

When in this mode the sound is disabled and when the machine first boots up in a blue screen it says something about the display driver.  

If anyone could assist in telling me what the problem is and how to fix it. It would be greatly appreciated.



It appears the lines don't show up in screen shots.  Oh and one other things, the lines go away, like now for instance.  The other problem I'm having is the computer shuts down by itself sometimes taking a long time before I can get it to start again in safe mode.

Hope someone has some answers.
