When It wont light up or do anything.
The connectors on the ends of the cables are hard to get seated.
After seating the connectors, the pins need pushed back into the connectors.
Step 5 is for doing a complete driver re-install, these are the links you need, if you have to do this.
I spent days trying to figure out why my I/O Drive stopped working, and couldn't find anything, other than re-install drivers, which does not help if the cables are loose. So here is my guide that worked for me, good luck.
Step 1: Remove Sound Card and I/O Drive From Computer
Remove the sound card and I/O Panel.
Step 2: Re-seat Connectors
Using something plastic and flat (this was the back of a small screwdriver) push and wiggle each side of the connector into the board
You really have to push and wiggle to get these things to go all the way in.
Dont forget to do both sides.
This Picture is from inside the case after I fixed it, but remove the card before you work on it.
Step 3: Fix Pins
They are the shinny parts in the pictures, where the red arrow is pointing.
Take the flat end of a small screw driver and gently push each of these rings back in towards the board.
Yes, you have to do it for every wire on both ends of the cable.
Step 4: Re-install Sound Card
Push it back in the slot.
Turn the power switch on, boot up and see if it works.
If not go to the next step.
Step 5: Drivers and Other Problems
Open control panel and go to add remove programs
Remove any creative software.
Shut down computer, turn power supply off, take sound card out of the mother board
Run Driver sweeper (link in intro) and select creative, remove all left over files
Download latest drivers (link in intro) dont install
Shut down computer, turn power supply off, re-install sound card to mother board
Install new downloaded drivers, click yes to reboot after install
Run creative auto uodater, download all updates ( you dont need, wave studio, midi player, or media toolbox, if you dont want them)
Click yes after they download to install them
Reboot after all updates are finished
Check control panel /sound to set your default device.
And dont forget to plug your speakers back into the sound card
