When i boot my pc while i use my external vga , it boots but no display , so i have to use the on-board. after a while using my on-broad vga i shut down my pc and connect the cable to the external vga card it works again. it's a bit of a problem , anyone have a problem like this ? Is there a solution ?

Is this while using a laptop? Are you wanting to run both screens at one time, or just the second add-on display? If it's the laptop, try pressing the Function and LCD/CRT button at the same time to switch between displays. If you want both displays, you must configure this through your display properties.
