USB ports stopped working.

Page-

This morning I found that, for no reason I can think of, none of my USB ports are working. The ones I'm most concerned about are the 2 onboard ports in the back. Device Manager says they're working just fine, but there is no response at all when I plug in my mp3 player, my camera, or my arcade stick, from my computer or the device (e.g., when I plug my mp3 player into a USB port of any kind, even one it won't work with, it will power on and possibly start charging. When I plug it into my comp nothing happens).

These are older ports I'm dealing with, 1.1 as far as I know. My OS is XP SP2.

I've tried every solution googling has offered. Unplugging the comp for a while, uninstalling and reinstalling the drivers, turning off the "Allow this computer to turn off this device to save power" option, going through the BIOS to make sure nothing was changed. No dice.

Any ideas of how I could fix this, or at least what could have caused it?

I have no advice about the issue per se, but I would recommend updating to SP3, which might include a fix - as unlikely as it is.

Doing so right now, though my windows update is being kind of dumb; I downloaded SP3, but I don't see any option for installing it.

Also, I should ad that I did replace my sound card around the time this happened, though I can't see why that would make a difference.

Some soundcards have USB controllers on them, what card was it? My Audigy has a connector so I can add some extra USB ports and even a Firewire port, your computer might be trying to use this controller on your new card and it's not working, or something along those lines.

Worst case scenario is that you shorted your USB ports somehow when you replaced your soundcard.

It also seems to have messed with my onboard audio, as well.

Try using Driver Cleaner Pro, have it delete all Creative drivers/files and restart your computer, hopefully this should solve it.

Hasn't worked. :I

maybe a power problem? does your soundcard draw more power than the old one you had?

granted i'm sure it would cause a whole lot of other problems, not just USB issues

Well, I'd think there'd be some indication in the device manager, at least. Like I said, according to that everything is ship-shape. That's only for the 2 onboard USB ports -- the 2 in the front aren't even showing up anymore.

Try removing the sound card and uninstalling its drivers. It seems to be a possible culprit, take it out of the equation.

Try safe-mode as well.

last time this happened to me it was a precursor to slow motherboard death. Have you been having overheating problems or restarts?

Basically, this is how it went down, from what I remember:

USB ports weren't working, then I replaced the sound card, they still weren't working, neither is the onboard sound (which I had been using until then without issue). The actual removal of the sound card happened when I wasn't there, but I'm certain the USB ports weren't working before I put the sound card in.

Other than that, it's been running a little slow and once when I turned it on it switched to a dual monitor desktop space (with scrolling), even though I've only got one monitor plugged in. That went away with a restart.

I really hope it's not the motherboard again. I just got this one like 3 or 4 months ago.
