"Drivers" installations for sound adapters (and video adapters, and many other devices) always include associated software that must be installed properly as well as the actual drivers.

You DO NOT install drivers for a sound adapter while booting into Windows, if the software for the device has not been installed yet - when Windows detects a generic device or Found New Hardware pops up while booting, you allow it to search for drivers, it doesn't find any, and it wants you to show it the location of the drivers - CANCEL that, continue on to the desktop, and install the software for the device using the proper installation from a CD or the proper installation file that you downloaded from the web.

DO NOT install sound adapter drivers when Found New Hardware pops up no matter when it pops up !

If you DID install drivers that way,

(The following also applies if you want to re-install the sound software)

- go to Control Panel - Classic View - Add/Remove Programs and Un-install the software you installed, reboot, DO NOT install drivers while booting.

- go to Device Manager.
(e.g. RIGHT click on My Computer - Properties - Hardware - Device Manager)
If the sound adapter is still listed, RIGHT click on it and Un-install it.
If that was there, and you un-installed it, Reboot at least once.
DO NOT install drivers while booting.

Install the sound software properly by running the proper download you got from the web, or if you have the CD that came with the sound card, or the CD that came with the computer that has the Drivers on it, run the sound software installation from the installation program on that.

You MUST remove the AC power to the computer when you do anything inside the computer case, otherwise you can damage something - the card, or the slot circuits, or both, because when the power supply is receiving live AC power, the mboard is always powered in some places even when the computer is NOT running. Did you do that AT ALL TIMES ?

Don't install anything except a video card in the last PCI slot closest to the center of the mboard. That slot is usually forced to share it's IRQ with the video, and any card other than a PCI video card is likely to have problems when installed in that slot if that's the case for your mboard.

If you want to confirm that, the mboard manual often specifies which slots share their IRQ with other devices or other slots.

If the card is not detedcted at all in the PCI-E X1 slot...
Depending on what you have installed in slots, NONE of the possible IRQs the Creative sound card can use may be available when it's installed in that PCI-E X1 slot.
See the mboard manual.

"....will not run a graphics card on the pci express x16 slot"

Which graphics card ?

Have you tried the same card with another computer ?

What is the (max total output) wattage capacity of your power supply ?

You MAY need a power supply that has more wattage capacity, depending on what video chipset is on the card.

Your power supply must have at least the minimum capacity required to support a system with the graphics card you are using installed, or the max graphics card you might install in the future.
(Onboard video - video built into the mboard - IS NOT A CARD ! )
If that info is not in the ad for the video card, you can go to the video card maker's web site and look up the specs for the model - often under system requirements - the minimum PS wattage, and, more important, the minimum amperage the PS must supply at 12v is stated. If you don't find that, any card with the same video chipset including any letters after the model number has very similar minimum PS requirements. Some power supplies have two or more +12v ratings - in that case, add those ratings to determine the total +12v current capacity.

If you're a gamer...
In most if not all cases, the max capacity rating of the PS is an intermittent rating. It's recommended that you do not load your PS to any more that 80% of that rating if you are going to be using something that puts a constant load on it, such as playing a recent game for hours on end. In that case, you multiply the min capacity stated for the system with the particular video chipset on the card by 1.25 to find the min. capacity of the PS you should have.
