hello,

 

 

 i see that is an old socket 775 mobo I have a p5n-d myself, what video card are you using?

 

there are multiple prognosis for this...

 

did it just start  blacking out or has it been like that for a while?

 

i fully understand the angst associated with this, it is right up there with a TV not turning on or something.

ok, that is the onboard vga out. that uses system RAM from your motherboard. i would guestimate that it has probably had a card in it and it was removed, so now you need to go into BIOS and check settings there to disable pci output. sometimes it is called PEG. then save BIOS and reboot.

 

another path is to enter safe mode. that may supply some indications also.  typically safe mode is engaged by a firm tapping of the f8 key right at power up.

 

this happened to me a few weeks back. i was resurrecting an AMD system. it was a newer phenom though, and the onboard switched on automatically without the previous card being installed.  but the older BIOS edition like yours may need to be manually changed.

 

my p5n-d has no onboard vga out, so it is the card or none, kind of eliminates the guesswork.

 

if that doesn't get the display going, you can try a BIOS reset, simply remove the cmos battery for a time measured in a few minutes and put back in, that restores the BIOS values to original config.

I can't see anything on the screen, so I tried ti take of the small battery for a while then put it back didn't change anything.

I am now trying to find an video card to try the screen on and see  ...

could you get into  BIOS and check for settings there?  i think it is the f2 or del key that you press immediately after power up.
