You cannot have two video outputs running at once, If you really want two monitors, you need to buy a card that supports two monitors.
Are your electrical outlets well-grounded?


Check you 2nd monitor, it could be discharging HV or your connector VGA.


Make sure both monitor work at same fq. or refresh rate.





Helpful to know what video cards you bave on same PC.

Hey. You can not make two monitors work at once without a computer overload. Hey, would you like to join me in the KKK. I will make sure you get a free lifetime membership.
Try setting the additional card as your primary in the bios and use your onboard as the secondary. makes no sense logically but it worked for me.
