SOURCE: no sound

1. plug in some headphones into the jack.
2. connect to an amplifier or external source.
3. connect midi to a midi-compatible device and determine if device receives signal by pressing keys

If #1 or #2 passes, your speakers are bad.

If #1 & #2 fail, but #3 passes, your setting are set so that there is no sound, but the keybourd still recognizes input.

If all three fail, the keys do not send a signal at all, you should replace the keyboard.

Storejet 25m 500gb not detected in my computer. device driver problem found. device driver software cannot reinstall.

Perhaps you should download updated software of your external hard drive. If still not working maybe your external hard drive is not supported by your OS or isn't compatible with your OS.

My computer will not boot up with the Grandtec Keyboard 2500 dongle in the USB port. Once it boots up, I insert the dongle and it works fine. I had this problem with the Vista OS and now with the newly...

This sounds like a driver issue .... after plugging in the USB dongle, go to the Control Panel>System and Security>System and select Device manager. After Device Manager opens up you should see "Keyboards". toggle open the triangle, to the left of the word "keyboards", and you should see the 2500 listed. If not, right click on the keyboard listed and select update driver software. Then select "Search automatically for the updated driver software". If a new driver is found, it will ask you if you want to use it. If not, try uninstalling the driver that is there and re-booting your computer. Then when you plug in the USB dongle it should automatically install the needed driver.

Try opening Device Manager in Control Panel and deleting the driver. Reboot, plug the mouse in again and see if that works.
Alternatively try restoring your PC to before your last update.

My hp1210 printer does not work on window 7 os

This all-in-one should work with the drivers built into the OS. First make sure you have a good data cable (go for a direct cable connection - no USB hub or print server). Next check for updates in Windows Updates. I've had a few printers where the new hardware was found but the driver update was held in Windows Update.

I hope this helps.

Vista Home Edition Driver Problems

Hi Ajay.

It would be best if you take a back up of important files from your OS drive and make a clean installation of the OS again. There might be an issue of corrupt OS files.

Hope that solves it.

USB recognizes it, but not the OS. I get no drive

Hello, nkhamo

Now, when you say USB recognizes it, do you mean you see the drivers being installed? Because if you are the OS is recognizing something has been plugged in.

Sometimes updating the USB Drivers will be needed. Do that by visiting the maker of your computer and search for Drivers and Updates on their Web Site, look for 2.0 USB drivers class, download that package to your desktop. The driver might be in the form of a Zip FIle. In that case, unzip the files using standard WinZip program or use software provided by computer, to a folder called cab. The driver program might show preference were it wants to unzip to. If so, let it do its thing. Then afterwards find the folder (cab or other folder) run USB driver by clicking install exe file. Note that all periperials need to be unconnected from all USB ports ( the port the laser printer connects to the computer at ) before updating USB drivers. So check cables for solid reconnection after installing drivers.
Its important to recognize the os you have. You'll find that information by clicking on Start Menu > Settings > Control Panel > System.

After doing this update, reconnecting the hard drive via USB Port.

Good luck, jasahasch
