  • Mobo wont output VGA

    Ok guys this is driving me crazy.... I finally got time and the parts to get my carpc installed and after i get it installed im having trouble booting which is a problem with my psu that i can get sorted out, but my problem is... On my EpoX 8rgm3i I hooked up a scrren to the onboard vga and i cant get any vga signal out of either vga ports...

    Ive changed everything, psu's, cpus, removed everything (sound cards, usb devices), even unhooked the HDD's... and i cant get anything


    Any help please

        have you tried to reset the bios? perhaps it's trying to initialise a PCI card or something instead of the onboard gfx. is there a jumper for that? usually it's a bios setting so resetting the bios may help.

            alright well i got it figured out... seems like one of the pins in the pinmod of my cpu got a little messed up and was causing the problem

                so is the pc booting at all with no display, or is it just not getting to/past the bios?

                    how about the vga cable? could it be the pins inside that are broken? I know you said everything, but what if you missed that one?

                        my feeling in that case is that you have some faulty hardware. I hope I'm wrong, or that it's still under warrenty

                          maybe you need "loads" on the video output, i had to put 75 ohms resistors in parallel with the r,g,b outputs, to validate it ???

                            ok so are you using a pci vid card or something? cause you said both vga ports? if you are, remove the pci one and trouble shoot using only the onboard. If you arent using a pci one, try using one and see if anythin comes up...

                              no it is onboard video, this board has two vga ports for multiple montior output
