Im thinking of getting this motherboard but will this graffics card work if its a in novision 8400GS 64bit DDR2 256MB

Yes, but check your BIOS and make sure the PCI-E slot is enabled.

Also, when you say doesn't start, you mean just the screen? Right?

typically Acer devices cannot be upgraded...that's why they're so inexpensive....sorry

Verify four things:

1. You are not plugged into the onboard video VGA port

2. Onboard video is disabled in BIOS.

3. Power is actually being applied to the card(make sure the fan spins up)

4. Reseat the card and make sure it is seated properly.

- try to reset your MB by jumpers
- try change your memory dimms

There should be no reason why this card won't work with Windows 7 32bit, it could be as simple as your Graphics drivers are out of date. I recommend downloading the latest Windows 7 drivers for your card at the Nvidia website.

Just remember graphics RAM and SDRAM are two completely different things so they don't add up.
As far as I know the 8400GS is a 256MB card.

Yes it is.
Nvidia 8400GS 512MB is PCI-E Card Ready for and 100% Compatible with this Motherboard.

You are just about at the "top of the line" for that motherboard. AGP is now outdated and your board does not support PCI express. The only boost from the video card you can get is a ATI 9800 Pro or equal. Although the 9800 doesn't support shader 3.0. Your memory is also low. Try getting another 1 GB ram. Best bet is a new motherboard with PCIe and 2gb or more ram with at least a video card with 512mb GDDR3 or more.

Sounds like a dead card

Hi Carpeteddy,
The ASRock K7VT6 motherboard does not have a intergrated graphics card onboard. So your 1.5V, AGP8X / 4X card needs replaced. It wouldn't hurt to uninstall the AGP's driver software, reboot the system & re-install the software. Check the manufactures web site for updated driver software before replacing it.

Here is a link to an XFX 1.5v AGP card:

The good part of XFX is its warranted for life!

Good luck Carpeteddy!
Questions?

You do know you can increase your integrated video's memory in the bios. Up to 1GB. (Yes, I know you currently only have 1GB of system memory) but you can kick it up to 128Mb & Vista should still run.
Your 1GB system memory is shared with the on-board video card.
I'd like you to clean out the PCI-E slot with some cotton swabs & house hold Alcohol. (do not over soak the swabs). Clean the pny's copper contacts as well. Get a really strong flash light & look into the PCI-E slot & look for dust, dirt & check the copper connectors are not bent or twisted. Re-install the PCI-E card & set the bios back to PCI-E. Try again. Even if the system reverts to weird, install the 8400's software & driver. Re-start the system. See if the system runs normal. Also would not hurt to check for Window's updates. After all that, if system does not function normally I suspect there is something wrong with the 8400 card.

Good luck & let me know if this has helped.
Have a great day.
