How to Add RAM to Your Pc

 These instructions are intended to be used in conjunction with your model-specific owner manual.
Note: The memory module contain electronic components that are sensitive to electrostatic discharge (ESD). Improper handling could damage your computer. Leave the module in its protective anti-static bag until ready to install, and handle it only as instructed by your Computer Manufacturer. If you have reservations about installing the module, ask for assistance from a qualified technician.
INSTALLATION PROCEDURE
1. Place the computer power switch in the "off " position and disconnect the AC power cord.
2. Remove the computer top cover following the instructions in the model-specific owner manual.
3. Before touching any electronic components, make sure you first touch an unpainted, grounded metal object to discharge any static electricity stored on your clothing or body.
 4. Locate the memory expansion sockets on the computer motherboard. If all the sockets are full, remove smaller capacity modules to allow room for higher capacity modules.
5. The ejector tabs shown in the illustration are used to remove a module. By pushing outward on the ejector tabs, the module will pop-up from the socket and it can then be removed.
6. Handle your new module carefully; do not flex or bend the module. Always grasp the module by its edges.
7. For most installations, DDR modules can be installed in any available expansion slot. Other installations may require the memory to be installed in a particular sequence based on the modules capacity. Check your owner manual to determine the correct installation sequence for your configuration.

Insert the module into an available expansion socket. Note how the module is keyed to the socket. This ensures the module can be plugged into the socket one way only. Firmly press the module into position, making certain the module is completely seated in the socket. The ejector tabs at each end of the socket will automatically snap into the locked position. Repeat this procedure for any additional modules you are installing.

8. Once the module or modules have been installed, the computer top cover can be reinstalled.
9. Plug in the AC power cord and reinstall any cables disconnected during the installation process.
10. Turn on the computer and follow the instructions in your computer owner manual that describe the steps necessary to allow your computer to recognize the newly installed memory.

Know the Computer to Connecting Tv problems

Computer to TV Troubleshooting

HDCP Problems: **The majority of high-definition DVDs and downloadable content is copy protected with a technology called HDCP (High-bandwidth Digital Content Protocol). This means that every piece of equipment you use to play HD content must be HDCP-enabled -- everything from the computer to the cable to the HDTV. If you can't play HD content through your computer, than your graphics card might not be HDCP compliant.

**The biggest problem with connecting your computer to your TV is that, generally speaking, computers and TVs don't display at the same resolutions. For example, the closest thing to the HDTV resolution 720p (1280 x 720) is a monitor display mode called XGA (1280 x 960). Not quite the same. And the closest thing to 1080p (1920 x 1080) is a monitor display mode called WUXGA (1920 x 1200). Again, not quite the same.

The result, in most cases, is something called overscan, where the full computer screen image doesn't fit on the TV screen. Overscan is a bigger problem on SDTVs where the native screen resolution is much smaller than your computer's display. If you're going to use an SDTV as a monitor, plan on lowering your screen resolution to 800 x 600.


**HDTVs also have overscan problems, but usually only the very edge of the computer image gets cropped. A bigger problem with HDTVs is when the TV refuses to display a signal that doesn't fit its native resolution.

Luckily, most HDTVs have the ability to scale incoming signals to match their native screen resolution. This involves either upconverting lower-resolution signals in the attempt to bring the resolution up to high definition or downconverting higher-resolution signals for lower-resolution screens. It's not perfect, but for most casual viewers, there's little to no noticeable loss in image quality.


**In rare cases, the HDTV won't recognize the resolution of the signal sent by your computer. When you connect an external display to your computer, most graphics cards will automatically try to find a good match for the display's native resolution. If this doesn't work, you will probably need to edit your resolution with third-party software.



Two programs are considered the best solutions for solving connectivity problems between a computer and a TV: PowerStrip for Windows and DisplayConfigX for Mac. Both of these programs allow you to match your graphics card's resolution precisely with the native resolution of your TV. If your HDTV is 1080p, you can go into one of these programs and switch your computer's resolution to 1920 x 1080, even if this wasn't previously an option.

Avoid increasing the refresh rate on your graphics card, unless you have a 120-hertz HDTV. If you send a signal with a refresh rate over 60 hertz to a normal HDTV, you could damage the TV.

Computer to Tv Connecting cables

S-Video cables

­If you read our article "How do I know which cables to use?" then you know there is a baffling number of audio/video cables on the market. You'll have to make some sense of the different types of wiring necessary to connect your computer to your TV. First you need to figure out what kinds of audio/video outputs your computer has and what kinds of audio/video inputs your TV has. If you're lucky, you'll find a match right away. But depending on the type of equipment you own, you may need to get creative.

First, let's talk about which cables you'd use to connect a computer to a standard-definition TV. The most common video inputs on an SDTV are composite, S-video and component video. On computers, the most common video output is S-video. On a desktop PC, you'll find the 9-pin S-video jack on your graphics card next to where you connect your monitor.

Some Windows laptops also have S-video-out jacks, but most have 15-pin VGA jacks for connecting to external monitors. Luckily, it's easy to find adapters and special cables that have VGA connectors on one end and S-video connectors on the other. Apple also sells a wide variety of adapters to connect Mac desktops and laptops to the S-video or composite jack on SDTVs.

Even if you have an old TV that only accepts coaxial video cable (the one-pin variety that's mostly used for cable TV and satellite connections), you can use something called an RF converter box that can convert S-video or VGA input into coaxial output.

For connecting a computer to an HDTV, it's the same story. The most common HDTV inputs are component video, DVI and HDMI. If your graphics card doesn't have one of these outputs, then you'll need to buy a special converter box or adapter. For example, if your computer only has a VGA jack and your HDTV only accepts HDMI, then you'll need to buy a small box that will convert the signal for you.

Wireless Connections Apple TV is a small device that lets you connect your computer (Mac or PC) to your widescreen TV wirelessly. While you can use it to watch movies and TV shows through iTunes and browsing photo libraries, you can't use it as a regular computer.

If you're serious about playing high-definition content from your computer on your HDTV, then you should upgrade to a graphics card with a DVI or HDMI output. Most newer Apple laptops come with a Mini DisplayPort video output that easily connects with the DVI or HDMI inputs on an HDTV.

All of the cables that we've mentioned so far are video-only cables, which means that you'll need separate cables to handle your audio. The easiest solution is to connect some computer speakers to your audio card's headphone or audio-out jack. If you want to use your TV's built-in speakers, then you'll need to buy a 1/8-inch stereo mini-plug-to-RCA cable.

For the best possible audio, you'll need to invest in an audio card for your computer with either an optical or digital coaxial audio output. These connections carry high-bandwidth digital audio signals using cables that can be plugged directly into your home theater receiver.

Even if you have the right cables and have done your homework about resolutions, you still might have some problems connecting your computer to your TV.

In the next section, we'll share some troubleshooting tips.
