Since the processor does not have Onboard Graphics, as soon as you turn the computer on the video card connected to the system should bring up some image.
In the case you are not getting any image you can try with another video card in the system. Also, if possible try again taking the battery out and BIOS jumper out for about 10 minutes. When doing this, make sure the power supply and other components in the motherboard are disconnected.
If you are able to access the BIOS after doing these steps, enable the Legacy boot (needed if using Windows 8 ir higher Operating Systems).
