Q. All of the sudden they stopped working. It is a desk top computer. They are plugged in to the computer and to a power strip, they are turned on and the volume is turned all the way up but all I here is buzzing nothing else. When I check the computer it says under sounds and audio devices it says no audio device. I have tried to install them but it will not work. What can I do?
A. Hey Amanda,
Steps to fix :
1. Make sure your speakers are plugged in,turned on, and properly connected to the computer. You've probably checked this, but it's amazing how little problems like this (or the computer's sound being muted) manage to confound people.
2. Plug the speakers in to another computer, if possible. If the speakers work with the other computer, proceed to the next step. If they don't, you've probably got a problem within the speakers themselves.
3. Check to see if your PC is still under warranty. If it is, do not proceed. The help provided below may void your warranty. Contact your service provider if this is the case.
4. Check your sound drivers
* Open your start menu (right-click on the "Start" button and choose "Explore"), and find the "My Computer" icon. Right-click on it and choose "Properties" from the submenu. Click on the "Hardware" tab and then the "Device Manager" button.
* Expand the "Sounds, video, and game controllers" heading to find your sound card. The name will depend on what sound card is installed on your PC. It will most likely have a name containing "audio." It should look something similar to the example above. You'll know immediately if there is a major driver error because an exclamation point (!) will show over the card's icon.
* Double-click on the name of the sound card to open a new window. In the new properties window click on the "Drivers" tab. If there is no "Drivers" tab then you chose the wrong sound device. Go back and try again. On the "Drivers" tab, click the "Driver Update" button. Follow the Wizard's onscreen instructions to update your driver. You can also contact the manufacturer of your PC for the most recent audio drivers. They can usually be found online.
o If you already have the most recent driver, click the "Uninstall Driver" button. Then restart your computer. When you restart your computer, the driver should reinstall automatically. If it does not, install it manually with software (or a download) from the manufacturer.
5. Check the "Windows Troubleshooter". On the "Drivers" tab mentioned in the step above, there is a button for troubleshooting the device. Click on that button, and follow the instructions on screen.
6. Check the sound card itself. Properly shut down your PC and then disconnect all cables on the back of your PC, including the power cable. Open up the CPU, making sure to touch a grounded metal object (a doorknob or metal desk will work, for example) before opening up the case. This will discharge any static electricty you have built up, which could damage your computer.
* Locate the audio plug on the back of your PC. The sound card should be in the corresponding location on the inside of the PC. Remove the sound card and put it back in. The Microsoft site has detailed directions for installing a sound card; to remove one, simply do the reverse. Once you have the sound card back in, reattach the cables you unplugged earlier and boot your PC.
Tips
* If your sound card is built into the motherboard do not try to remove it. Your entire mother board will be needed to be replaced if the sound card is the problem. Another option is to buy a seperate PCI sound card and then install it.
* If you're having problems with speakers emitting a static or crackling noise, it may be caused by a high speed internet box. Moving the box away from the speakers or the speakers away from the box may help if this is the case.
* In some cases, you will be receiving high amounts of static from the "CD Player" and / or "Line in" channels. This can be corrected simply by lowering the volume or muting these channels in Volume control (Start>All programs>Accessories>Entertainment>Volume control)
Hope this will be of some help for you!

Whats the difference between Computer Science And IT?
Q. As the question states i want to know the difference and what is recommended for me to take..
I like dealing with software more than Hardware..I am better in the practical usage of software...
So could u recommend what to choose as a course in college?

A. The simple answer is if you want to create, write code and test software programs or web applications this would fall under Computer Science.
The thing I always tell people interested in Computer Science is that they need to discover not if computer science is a good major for them but if they are the right person for computer science. Programmers are born and not made. All the computer programming courses in the world will not make you any good at it if it is not your gifting and calling. Many eager CS majors take their first few programming courses and realize that this is not what they expected while others just take to it like a duck to water. If you find yourself struggling you can always switch majors into Info Sys or another IT area that does not require programming. Remember that at most 4 year schools you can change majors out to the end of your second year with very few credits or time lost. Being able to do well at CS has nothing to do with intelligence. Many of the people I know that were not successful in Programming are very successful in other fields.
If you want to be a Computer Technician, Service Center Coordinator, Help Desk Staff, Storage Administrator, Network Administrator, Systems Administrator, Systems Engineer, Enterprise Administrator, Active Directory Administrator, Exchange and Messaging Administrator, Backup Administrator, Disaster Recovery Specialist, Database Administrator, Computing Security Specialist, Corporate IT Acquisition Specialist and Data Center Administrator, just to name a few you would go into IT.

how do I configure a gpo to restrict users from stopping the terminal services service?
Q. I am looking in the group policy management console and I cannot find a way to keep users on the domain from setting the terminal services service to manual. The problem I am running into is we have some semi Microsoft savvy software engineers that think they are doing a good thing and blocking weaknesses, the problem is when they want us to remote into their pc to fix issues we have to wait until they are at their desks to start the terminal services service.
A. Simple: Open an existing GPO or create a new one. Edit it and under Computer/Windows Security/Services set the Remote Desktop service to automatic. Further restrict it by setting who can query the service by removing the Users rights to read it. The user will not be able to change their terminal service startup. One catch is if they are able to edit the registry, they can change the startup DWORD to 4 or 2 (disabled/manual respectively). You can prevent this by blocking users from being able to use registry editing programs (GPO). Then, if they're still able to get to edit the registry, block their rights to regedit.exe and regedt32.exe (GPO). That should hold them at bay.
If that's not good enough, edit the computer configuration Computer/Windows Security/User Rights Assignment (I believe) and set the "Users that can connect to this computer via Terminal Services" to trusted users only (or none).
Finally, don't allow anyone to have local administrative rights on the computers. If you do, you're not going to be able to stop them from blocking the GPO from being applied, as they can restrict this via the registry...
