I have a Gigaware 4GB MP3 player, and suddenly my computer will not recognize that it is plugged in. I've searched for drivers for it, but can't find anything. It was working until the other day. It won't play, or do anything. Any ideas on what I can do to get my computer to recognize it? Are there drivers for it? I'm at a loss.

Your 4GB card is actually a microSDHC card. The e250 works with microSD cards, 2GB and smaller.

You need to install the driver.

I'm not with this brand specifically, but it does sound a lot like the iPod so I will try to help...
Even though the battery is most likely fully charged, it will continue to show the battery symbol to show that it is charging/charged. Depending on the brand, there will be a different symbol between a charging battery and a charged battery.
As for your music, make sure you have the most current driver(s) installed on your computer.

wrong category
try it on another computer

Try plugging it on an another computer. Maybe the USB port is in problem if it cannot powers up the player.

Download the drivers from Creative Labs, or with the disk included with the MP3 player.

Find the MP3 player in the device manager, delete it, then plug it in again and see if Windows recognizes it and reinstall the drivers properly.
If on the second try windows does not install the device drivers properly, find it in the device manager right click on it and click update drivers

try to reset it

Thanks for your offer.
the player requires wmp 11 in order to be recognized.

Try plugging your USB cable (attached to your player) into the computer before you turn the computer on and boot up . . . I had this same problem with a flash drive that the computer would not recognize if I plugged it into the computer while the computer was already on.
