I have a PIII server, 700mb RAM, 500mhz.. the video card just, quit.. i replaced it with antoher video card.. that too wont work.. i know for a fact both cards are in working order, and it isnt my monitor... what is the problem? i cleaned out the whole computer last night, unplugged EVERYTHING then pluggd it back in.. still have the prob.. what is up??
maybe the port on the motherboard is the problem...
which port? please explain..
The slot, which the card plugs into. Or the electronics that control it.
I'm assuming it's an AGP slot? Try getting an ancient PCI video card and see if that works.
ive checked, one card is normal PCI, the other one, i dont know what it ism, its a vid card, that has a SPECIAL slot.. well the one vid card with the special slot, well theres only ONE slot.. so i cant check on another slot.. i tried ALL the PCI slots.. no video.. but the ethernet card blinks.. so no probs there..
How did you ever find a replacement video card if you don't know what the SPECIAL SLOT is? In all likelihood it's AGP:
How do you know the problem is even the video card? I've seen ethernet cards blink when the computer is OFF. So all blinking means is that it's receiving power, not that the computer's working.
For that matter, maybe your monitor died 
no by blinking i meant that the slots recieving power.. and the card is AGP.. i had to think for a second.. i have one AGP and one PCI.. i tried pci on ALL slots, no work.. i tried the AGP in well, the one AGP slot and it didnt work... the AGP was the ORIGINAL video card.. i just had the PCI lying around..
So what you're saying is, the computer doesn't boot, at all, ever, or even react, at all, ever, no matter what you do with it. It may be dead dead, not just dead-video dead. I don't suppose you have a POST card.
What is the OS and version? If it is unix/linux then it probably will boot without a video card (assuming that the motherboard/cpu/memory is not damaged.) Can you ping it?
Does the speaker beep? if so count the beeps and check the BIOS manual for that motherboard.
Find a DOS/Win95/Win98 boot diskette and try to boot from it?
When did that change? Having no video used to be a beep-code level error(and still was for anything but motherboards designed to be standalone, as far as I knew).
A computer that doesn't even POST could hardly be expected to boot from floppy.
ideo problems Dell Cpx? 850 PIII laptop
Customer has a 850 mhz PIII Dell laptop. The video gives up on it by the next day after he took it back each time. I've uninstalled the drivers and put the most up-to date ATI M3 drivers on. The ram checks out fine, the rest of the machine works wonderfully, it has no viruses or spy ware that I can detect. He said it happens in the mornings so I'm wondering if the CMOS battery could be dead. Could a dead battery cause no video to come up in regular mode?
