[Rvd]

For a testing purpose with Solidworks I installed Graphics Card on the H81M-S2PV board . yesterday I remove the cared and use the internal VGA but the display is not responding,I can access display via Graphics card ,I check the cable ,Power , Memmory . I don't find any solution to get the display via onboard VGA ..I think MY new H81M-S2PV 's VGA is dead ..is there any way to check it alive or not ...I fed up with the Gigabite Company,In my lab 18pcs use gigabite and every day get usual problem ... hmmm Please give any body to get solution to find out the VGA Is live or not
