Q. I've been looking around the internet, trynig to find the best processor for me to use in building a desk top computer. There are A TON of different processors between AMD and Intel. And I just don't know what to pick. The ideal processor would be one that can run advanced video editing software like Sony vegas pro 10 or what not, and has the capability of playing games like BF3 or skyrim. Oh, and my prefered budget would be around $50 to $100.
A. I like referring to these value lists that judge Passmark benchmarks by sale price:
http://www.cpubenchmark.net/cpu_value_available.html
http://www.videocardbenchmark.net/gpu_value.html
In the CPU list, the Phenom II X4 955 is the top contender (topped by less powerful Athlon IIs and Intel Celerons, and by more expensive FX eight-cores). Intel's better i5 and i7 series are also more expensive.
If by chance you were looking for graphics cards, the Radeon #750 models (the first digit is the series, while the next two numbers describe where within the tier they sit). Not sure how the GeForce numbering works… Here are some videos:

GeForce GTS 450 http://www.youtube.com/watch?v=ElUlIISMbWM

What can I do to fix my computer speakers?
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!
