Got an old P3 700 here where there is no signal from teh onboard video.
Have tried removing bios batt out of desperation with no luck. Have tried PCI vid card but can't get into bios to switch off onboard of course (doh!).

Any ideas?

Read the manual and see if its possible to disable the onboard via jumper.

Removing the battery does nothing for the new motherboards except reset the clock. The actual BIOS is held in non-volatile flash ROM.

If all else fails, try downloading the latest BIOS and flashing the motherboard. Hopefully it will reset the BIOS to defaults again.

tried that already, no option. - also tried new RAM....no change.

It may help to put the specs of the Mobo on here,

but as someone else said there is often a jumper somewhere to disable the onboard video

no worries although I have the manual here and can find no mention of disabling the OBV through hardware.

It's a jetway (I think) 630cf.

Cheers and thanks!

I suspect that unless it has an AGP port, which may take priority on boot up, you are stuffed.
I know it's hard to accept, that apart from the video fault the MOBO is good , but will have to be consigned to the bin. Just life I guess.

Tried removing the CMOS battery?

Random and seemingly redundant trash often comes in handy at the most irelevant of times...

yeah that was the first thing I tried.
don't really wanna trash the mobo as there is still nothing wrong with a P3 700...just a bummer is all.

Thanks for the suggestions guys.

I suspect that board will have an agp port, so see if you can obtain a cheap agp card to test

Try to clear the cmos with the clear cmos jumper and try a pci
video card again, I was going to say try a ISA video card, but I see
the m/b has no ISA slots either (does not have much, does it)
A pci video card should work after resetting the cmos as the default in the bios is usually display pci video first, if it does not work you may have other problems with the m/b or cpu, also don't rule out the power supply.
