Screen flickering only at the top of the screen...
what could have caused this ?

Possible dirty video card port ?? causing static maybe pls help getting really annoying and getting scary thoughs :( :( :(

or something more sinister....

my video card could still play games so not probably the video card..
 
Solution
There are a few possibilities, but it might indicate a hardware malfunction. It could be the video card (easy to test by trying a different video card) or the monitor itself. Have you tried different refresh rates (70 Hz or faster is best)?

Unless it's a high-end unit, used CRT monitors can be had for next to nothing.
