Then 3 days ago it just stopped being recognized by my computer and the light on the adapter wasn't lighting up.
My computer is windows 7 32 bit btw~
I assumed the adapter had died and bought a new one but the new adapter couldn't be recognized either...
I tried all usb ports but that wasn't the problem either.
When I insert the adapter I get messages such as "device has malfunctioned" "device not working" "device not recognized"...
In the device manager it shows unknown device in usb storage...
I tried downloading the latest driver from the manufacturer's website but that didn't help.
I decided to try the new adapter on my brothers computer (windows 7 64 bit) and it worked fine...
because I didn't know what to do to fix it, I tried system restore but it didn't help. I then reformatted my hard drive and put a fresh w7 on but it still wouldn't recognize the adapter.
I then installed windows xp and still nothing...
What can I do?

Quote from: MyNameIsRay No, my usb storage device won't work either.
What kind of usb storage device is it? Does it have its own mains power supply, or is it powered via the usb port?

If that fixes it, then it is probably worth replacing the BIOS battery, usually a CR2032 button cell.

Quote from: purleigh It might be worth going into the BIOS and doing "Load default settings" in case the USB or interrupt configuration has been corrupted.

Nothing changed after loading default bios settings
Quote from: purleigh Have a look through "How to troubleshoot unknown devices that are listed in Device Manager in Windows XP"
I tried to update those drivers but it is hard to find the right ones. This is the computer:
http://support.acer.com/acerpanam/desktop/0000/acer/aspirem1610/aspirem1610sp2.shtml
I found the realtek audio drivers easily but the others are hard to find:
But is that not unrelated to my usb problem?

Do you have a powered USB hub you could connect things through? I'm thinking the problem could be that the usb sockets are no longer providing sufficient power for the wireless adapter (which uses more power than a keyboard or mouse).

Quote from: ejs The device "SiS PCI to USB Enhanced Host Controller" must be the USB 2.0 controller on the motherboard, device manager doesn't show any problem with it.

I don't have a powered USB hub. But if that is the case would I need a new power supply or what?
I have an unused computer with a stronger power supply I could try

Yes a better power supply may solve the problem. I just read the specs on the acer link you gave - 250W is rather low.
