Graphics - Computer works fine but no graphics

[GemmaLouise]

Hello

i was wondering if any one has any suggestions on my problem, my computers runs fine , boots up and everything but no graphics show up on the monitor

i have tried a different monitor, a different graphics card, and i tried the on-board graphics, i have cleaned the computer, and checked for unplugged cables etc.

when i first performed these checks it worked for a couple of hours and went back the same, and then it came back for a couple of hours and went off again, and since then its not come back on at all

if anyone has any solutions i would be grateful to know

Thanks

Gemma

Have you tried another motherboard? it doesnt seem likely that it would be, but its the only thing that i can think of :/

Does the BIOS stuff show on the screen when its first turned on?

Try clearing the CMOS by removing the battery on the motherboard, and re-inserting it, and use the onboard VGA. If there is still no display, then there is most likely an issue with the motherboard.

Were you using the onboard graphics card when it began working again?
