I installed an ati all-in-wonder 8500 dv video card and now my computer hangs after the bios screen for about 15 min with a black screen before starting windows.

This problem occured before installing any of the drivers and persists though drivers have been installed and everything else works fine after it starts windows.

I've tried updating the bios.

Any ideas?

Most modern PCs need up to 4 drivers installed in sequence for the video card to function properly.

AGP mini-port driver for the motherboard / chipset

DirectX (from Microsoft) at least the lowest version required by the video card mfg.

The actual video card driver.

The monitor driver, if the monitor is not listed in the standard types.

Other things to check:
Any leftover files, system settings, or registry keys from the old card?
The best way to swap cards, is to remove the card from device manager, and check add/remove software for any utilities left behind.
You can also run sysedit, or msconfig to look for old driver statements.

Download the latest drivers from ATI.
The driver on the CD may be months old.

Check for updates to the video card BIOS.

Check the size of the AGP apperature in BIOS settings.
I recommend a minimum of 2X video RAM, up to 1/2 system RAM.

Try starting system in safe mode then go to device manager and uninstall older video if listed.

Good luck

Check the BIOS to make sure that it assigns IRQ for vid card and that it doesn't cache vid memory. Also you need the miniport (mobo) AGP drivers at a minimum.
