Im trying to fix a computer that appears to have a broken on-board VGA connector. But I tried installing a graphics card to bypass this and the PC still wont Boot. It turns on but no display. Have tried swapping the RAM and disconnecting everything but the RAM and CPU and still nothing. Could this be that the PC is still trying to use the on-board VGA and if so is there anyway to force it to use the Graphics card?
"I accidentally put this in the Foxconn subcategory and it wouldn't let me delete it so am reposting it here"
Depends on what graphics card you're trying to use and your power supply specs. Some low end or oem ps don't have enough juice to power up specific video cards. Start by listing your motherboard make and model number, same for the video card and power supply specs, including the 12v rail.
