video card problem

If you didn't disable the onboard video via the bios or with a jumper setting, try that. There might be some conflict with irqs between the video card and the pci bus. Hope this helps

After you install your new video card, you need to disable the onboard video either thru windows AND get nasty and check the bios to make sure you can disable it there too. You should then be ok with your new card.

Good luck.

There are a few things to check. First start with your BIOS and see if it asks if you have a PNP Operating System or not. If it does set it to PNP and then set the other options to "automatic" and "reset configuration". Save the changes and reboot. Watch the POST and see if it recognizes your PCI devices. Your video will probably use IRQ 9, sound card either 5 or 10 and your modem 4 or 3 or 12. With PCI it is not so important what IRQ it uses (within norms) as that the PCI bus sees them becausethe PNP OS will assign IRQs dynamically.

Another approach is to move the video card from one PCI slot to another. You may have a bad PCI slot or the video card is not being sensed in whatever slot it is in. Don't forget that you can use a pencil eraser to clean the contacts of the edge connector on your PCI card. Keep the rubber droppings out of your PCI slots. They are insulators and you don't need that sort of trouble.

I would say what happened here was that you blew away the driver for the onboard video controller when you reinstalled. You could have tried to identify the video chipset and downloaded the drivers rather than buying a new video card.
As the above answers stated make sure your onboard video is disabled, this will be done through the bios or via a jumper setting on your main board.
If it is disabled and you are still having problems you could manually asign IRQ 9 to a certain PCI slot and use that for your video, ensure that no other device is trying to use that IRQ. Maybe even try disabling PCI steering in your BIOS.
Good luck.

Sounds to me like you might have a bus-master card...disable bus-mastering in the BIOS and see if that fixes it...

No guarantees, but it's worth a try, anyhow...

If you pull out the s3 card and the onboard video isn't working, how do you know the other pci cards are working? When you say it is not working, I assume you mean that you are getting no video at all.
First the obvious: be sure your onboard videois disabled; if it is, be sure the other cards are pnp or set to pnp; be sure the bios is set to pnp; then be sure that all the cards are seated correctly... If all this is ok, then I would start to suspect the board itself, it's rare for an onboard video to go bad.

I also had an onboard video go bad. After installing the new card in PCI SLOT ONE and disabeling the onboard video via the bios settings I had to remove the sound card and modem card reboot the system so the PNP set the resources for the video thenI reinserted the sound and modem cards and the pnp seemed to set things up so everything worked. Hope this helps you have had many good answers and all have the possibility of fixing the problem.

answer 7 sounds most likely. This has do with BUS Mastering as mentioned above, as well. Without getting too technical, there is a confusion between your system and your PCI cards about which card is the PCI BUS Master card. If this and the BIOS advice above is over your head, try reorganizing each of your PCI cards in different slots. You should evnetually find that you put the cards into an order that will work. What happens is that once one card gets put in an slot (i.e. bus masteringcard in a non-bus-matersing slot) the othr PCI slots all failt to work. You can also try only putting in 1 card at a time. Get it to work. Then when yo find a combination that doesn;t work, switch them around, etc. Keep repeating this until yourget them all working.
