This probably doesn't have anything to do with the graphics card.
Are you going through a KVM type monitor switchbox? Try it without it.
Also make sure the monitor cable is fasted properly and not tangled around
a power cord. What you are describing sounds like electrical interference
problems.
If it's not one of those, did this card ever work properly?
It might be a bad card.
