Well definitely not your Monitor, hmm, if both your in-built and VGA give you garbled screen, it could be the OS messed up drivers. Does the post work? I am guessing not. Try to remove the graphics card and use the in-built port.

ok..thanx 4 ur help...its not about graphic card..i try to keep shaking the monitor cable and its colour turns normal again..so its maybe failure on its cable..thanx for your concern

Ahh, this could be your port as well or as you said your cable.
