.....I can only get blue and yellow color on my monito. What should I do?
That's probably not too good. Do you have a friend you can make a quick
monitor switch with? You should try another monitor for a couple of
minutes and see if another works fine, meaning yours needs to be taken
in or replaced, or the test monitor reacts the same which would lead me
to think you have a graphics card problem.
You haven't been doing anything lately that might have caused this have
you?
