well my pc onboard vga is not working so i bring the vga card and inserted in it and it starts but when the pc restarts there was no display and then when i take the cmos battery from the board it works fine and then after it restarts the same problem is coming again and again, can anybody help me please.
Sounds like drivers and need to disable on board vga. go to Control panel click on system security find device manager click on it find display adapters click on it then right click on the on board vga then click on disable. After that you need to up date drivers from vga card The people who make them like nvidia or amd depending on who makes your vga card. I hope this work for you.
