Yes, I did this already, I should have rephrased.

It says that "Windows has determined your driver for 'Unknown Device' is up to date"

i have had this problem before with wireless adapters and the best way i solved it was to un-install the driver and re-install manual i guessed you have done this?

Yes I have. But like I said, I'm updating the chipset for my mobo. It's halfway though downloading right now (about 15 minutes left), I'll update once I see the results.

I seem to recall that I had this problem a couple of years ago (the USB ports not working, I mean) before I switched to the 64-bit version, and that updating the chipset helped, can't remember for certain though. Hopefully it'll work this time.

And yeah, it's decidedly weird.

So the chipset update didn't solve the problem, so what I ended up doing was disabling/enabling the USB ports. This solved the issue, and I'm posting this from my win7 machine. Relatively simple fix.

Thanks for all your help, brianzion. I'm going to check out that program you posted, seems like it may solve some other issues I've experienced in the past.

EDIT [[Fix]]::: Disabling the USB Root Hub in the device manager was a temporary fix at best. Three of the ports remained nonfunctioning, and today when I had need of a flashdrive the transfer rate was horrendous (three hours for 5gb of files).

Looking into it further revealed that all that had to be done was disconnect the PSU from the wall outlet for a couple of minutes and then reboot. From what I understand this causes the mobo to reset, as it still receives power even if you've powered down your computer and are still plugged into the wall.

Now it's back at full capacity, just figured I'd update this in case anyone else finds themselves stuck in the same boat somewhere down the road.

When in the programs and components list in windows 7, I can no longer see all the programs installed on my system. This happened a week or so after I got the computer. It would really help if I had access to all programs through that function. Thanks
