line of red dots only appears on dark background
When I start my PC up a line of red dots appears across the monitor screen at the bottom of it. The line of dots again appears but higher up the screen when the windows screen appears. Both screens are dark in colour.
Also if I have a block of dark colour anywhere with a light coloured background about 3 or 4 lines (each line directly above the other) of red dots appear across most of this block of a dark colour but none in the light coloured background. In all cases the red dots do not form a continuous line across the screen.
My pc has an Intel i5 3570k processor running at 3.4GHz (not over clocked) with onboard intel HD4000 graphics. I do not have a separate graphics card.
Can anyone help me solve this problem.

line of red dots appears on dark background across monitor
Thanks for your reply. I have now had the chance to check my monitor and cables on another computer. When connecting another computer to my monitor the red dots did not appear on the screen at all. When connecting my monitor to my pc using an HDMI cable they still appeared on the screen.
I am now thinking that this problem is something caused by an interaction between a Windows update and the intel processor, as they did not appear when I purchased the computer initially and only started appearing after I had downloaded windows 7 updates
I have also noticed that if i move the mouse over the rows of dots when they appear in a dark block centre right of the screen the red dots disappear momentarily.
Any ideas on how to fix this problem would be very much appreciated.
