You either have corrupted drivers or you have a device conflict.
you'll need to uninstall and reinstall the drivers for it. (try to right click and update drivers, if this doesn't work, then you'll have to download the drivers from your MOBO manufacturer.

My dell mtc2 was reformatted and now does not recognize my speakers any thoughts

Hi beaglebetty,
The yellow question mark present in the device manager indicates missing driver software for your speakers and/or sound card.
You can browse to the manufacturers website and browse to their support section where you will be able to download the correct software to get your speakers up and running.
Please don't hesitate to message me should you need any further assistance or explanation.
Best wishes,

Sansa View: is not recognized by my computer

See myother TIP posted here on this site. About MSC and MTP Connection problems.

First thing to do is:
Try otherUSB ports on your computer. A USB port on the back of a PC usually has better poweroutput.
Try adifferent cable if there's one available, to rule out if you have a bad cable.
Tryanother computer.
If none of the above works:
Then-Check and refresh the drivers in Windows, for a Portable Device.
1 -Connect your player to the PC
2 -Check under Device Manager
-> 1.Right-click My Computer, and select Manage.
NOTE: The player should show up on the Device Manager's right pane as:
1. USB Mass Storage device (if the player is set to MSC)
2.Portable Device (if the player is set to MTP mode.)

(See my other TIP listed above for an Explanation of MSC and MTP modes)

If thereis a yellow exclamation point (!) or question mark (?) beside the device, tryto refresh the drivers.
Then -Refresh the drivers
1.Right-click the entry with the error mark, select Uninstall.
2. On thetop menu, click Action then select Scan for hardware changes.

If your BRAND NEW player is NOT recognized by the computer when plugged in:
This may becaused by one of the following:
1.Minimum system requirements were not met.
2.Corrupted drivers.
3.Computer restrictions, Vista or 7 authorizations.
4. Powerissue, plug your player into the back of the computer.

Next be sure you are using WindowsMedia player :
Version10 or 11
Downloadand install the latest Windows Media Player if it's not installed.

If all this has failed - Refresh the drivers again.

If allthat does not work - Manually add the hardware driver.
1. Connect the Sansa player in MTP mode
2. Manually install the device driver through Windows device manager in control panel. Install the Device as a Portable Device.

I have a Acer Aspire 5517 with Windows 7 65 bit OS. After I sent the computer in to have it serviced I got it back the webcam was not working, I have downloaded the driver, and camera still does not work,...

Make sure there is no yellow exclamation marks in Device manager and you see the device in the list like my HP webcam on the picture below.
10_10_2011_8_21_55_pm.gifRight click on My Computer, select Properties and click Device Manager.
If you don't see the device listed or there is indication for problem with it, please try this driver if the camera is Chicony or this driver if camera manufacturer is Suyin. If you don't know the brand of the camera try both of them.
You can also test if your camera is working on this site without installing additional software.Good Luck!

Scanner Not Recognized

You need to remove the yellow question mark on the device manager. Click on the plus sign of the Question mark icon. Right click on the item that will be displayed under the question mark and then uninstall. You need to uninstall the drivers as well. you can doo it on add/remove programs(winxp) or program features (vista). Unplug the USb cable/ Download drivers from and you just need to choose the right driver for your windows version. After Installing the TWAIN driver and Epson scan utility, you need to restart computer. When computer is ready you can plug in the usb cable and open up Epson Scan on your desktop
