What do you do with your old computer components?
Just wondering, what do you do with old computer components that you might not use anymore such as HDDs, Optical Drives, RAM, Monitors, Graphics Cards, etc.
HDDs and Optical Drives I usually sell them. There’s not much else use for them: old HDDs have the equivilancy of a DVD-ROM, old Optical Drives can only read CDs…
However, with RAM and Graphics Card, I bet you would never guess what I do with them: make keychains. Sounds weird, doesn’t it? However, old processors make really cool looking ones! Just rid of the pins and smoothen the edges a bit, and you’ll have one kickass looking keychain =D
What are the components of a computer motherboard and how do they work?
How does the processor make use of these components to achieve the services required of the computer (Accept data, process and give out an output)?
The motherboard of a typical desktop consists of a large PCB. It holds electronic components and interconnects, as well as physical connectors (sockets, slots, and headers) into which other computer components may be inserted or attached.
Most motherboards include, at a minimum:
sockets in which one or more CPUs are installed[2]
slots into which the system’s main memory is installed (typically in the form of DIMM modules containing DRAM chips)
a chipset which forms an interface between the CPU’s front-side bus, main memory, and peripheral buses
non-volatile memory chips (usually Flash ROM in modern motherboards) containing the system’s firmware or BIOS
a clock generator which produces the system clock signal to synchronize the various components
slots for expansion cards (these interface to the system via the buses supported by the chipset)
power connectors which receive electrical power from the computer power supply and distribute it to other components[3]
The Octek Jaguar V motherboard from 1993[1]. This board has 5 ISA slots but few onboard peripherals, as evidenced by the lack of external connectors.Additionally, nearly all motherboards include logic and connectors to support commonly-used input devices, such as PS/2 connectors for a mouse and keyboard. Early personal computers such as the Apple II or IBM PC included only this minimal peripheral support on the motherboard. Additional peripherals such as disk controllers and serial ports were provided as expansion cards.
Given the high thermal design power of high-speed computer CPUs and components, modern motherboards nearly always include heatsinks and mounting points for fans to dissipate excess heat.
[edit] Integrated peripherals
Diagram of a modern motherboard, which supports many on-board peripheral functions as well as several expansion slots.With the steadily declining costs and size of integrated circuits, it is now possible to include support for many peripherals on the motherboard. By combining many functions on one PCB, the physical size and total cost of the system may be reduced; highly-integrated motherboards are thus especially popular in small form factor and budget computers.
For example, the ECS RS485M-M, a typical modern budget motherboard for computers based on AMD processors, has on-board support for a very large range of peripherals:
disk controllers for a floppy disk drive, up to 2 IDE/PATA drives, and up to 4 SATA drives (including RAID 0/1 support)
integrated ATI Radeon graphics controller supporting 2D and 3D graphics, with VGA and TV output
integrated sound card supporting 6-channel audio and SPDIF output
fast Ethernet network controller for 10/100 Mbps networking
USB 2.0 controller supporting up to 8 USB ports
IrDA controller for infrared communications (e.g. with a handheld remote control)
temperature, voltage, and fan-speed sensors that allow software to monitor the health of computer components
Expansion cards to support all of these functions would have cost hundreds of dollars even a decade ago, however as of April 2007 such highly-integrated motherboards are available for as little as $30 in the USA.

Component Audio to HDMI Adapter
Gefen — Convert Component Video and Analog Audio to HDMI – The Component Audio to HDMI™ Adapter is a unique device that allows older analog devices to be integrated seamlessly into the modern home theater. This adapter connects component video home theater devices to HDMI™ compliant digital monitors. This adapter also takes analog L+R audio and encodes it onto the HDMI signal for the full HDMI video and audio effect. With the Component Audio to HDMI Adapter legacy home theater devices and computer systems can be easily connected any HDMI display for the full digital video and audio experience. How It Works – Simply connect the supplied Component cable to the input side of the Component Audio to HDMI™ Adapter. Then connect the RCA audio cables to the audio inputs of the Component Audio to HDMI Adapter. Then connect the HDMI display or projector to the HDMI output of the Component Audio to HDMI Adapter. The adapter generates the compatible analog to digital conversion signals for video and audio as well encoding the audio onto the HDMI to make the connection between the analog inputs and the digital output work. Features: Allows you to connect YPbPr HDTV sources to an HDMI™ display Encodes analog audio onto the video signal for HDMI™ video and audio Supports HDTV resolution up to 1080p HDMI™ compliant Specifications: Digital Video Amplifier Bandwidth: 165 MHz Video Amplifier Bandwidth: 350 Mhz Input Video Signal: 1.2 volts p-p Input DDC Signal: 5 volts p-p (TTL) HDMI Connector: type A (19 pin) female Video In: 3 RCA component Audio Connector: analog RCA L+R Power Consumption: 10 watts (max) Power Supply: 5V DC Dimensions: 4″W x 1″H x 4″D Shipping Weight: 2 lbs. Package Includes: Component Audio to HDMI Adapter One 5V Power Supply One 6 ft RCA L+R Audio Cable One 6 ft 3 RCA Cable Users Manual
How do computer components communicate inside the MPU (main processing unit)?
i was wondering how the components inside a computer communicate between each other, i know about paralel and BUS but i am not sure about the technical details
There is an address bus and a data bus. The address bus ‘turns on’ a particular storage location and then the data is sent down the data bus.
When an action such as doing a calculation is in progress the address bus accesses the processor and sends it data from a specific location. Then it sends more if, for example, two numbers are to be multiplied together. The address bus then accesses a memory location and sends the processed data to be stored there. This memory location can be the screen.
For letters it’s much the same as they are stored as numbers. The keyboard is accessed and its data input is sent to a storage location.
Then it all gets a bit complicated!

HD15 (VGA) Male to RCA x 3 Male, Double-Shielded, (VGA to Component Video), 75 ft — Not For Computer Use
This cable will allow you to connect component video devices to TVs or projectors that have VGA inputs.
can I touch my computer components without an anti-static wrist band?
I am building my own computer and I haven’t touched my motherboard or any of my PC components yet. but I am not sure if I can touch everything without an antistatic wrist band.Please help.
Yes, just keep the other hand on the metal bit of the case; so to ground any static.
6FT VGA Male to 3 RCA component video cable (HD15 3 RCA)
Python SVGA to RCA Component Video cables feature the unparalleled quality and performance that is needed when connecting HD Equipment. These cables fully support (Y, Pr, Pb), (Y, Cr, Cb) and RGB high resolution standards with a 75Ohm Impedance for a maximum Signal, making them the perfect choce for connecting your DVD player or HDTV Receiver to the component video input of a plasma, LCD or HDTV display. Often referred to as “Vesa” cables, they work with all progressive scan and HDTV signals including 480i, 480p, 1080i, 720p, and all other video signals with no signal loss Note: The Device to which the “VGA” connector is connected, needs to support Component video(which is actually “sync on Y”, Y-Pr-Pb)or “sync-on-green” for this type of cable to work. These cables are not compatible with computer monitor ports or Y/Cr/Cb video. Check your Plasma, Projector or HDTV manual, otherwise your picture won’t sync! In this case you need a “transcoder”.

Anyone know a site where people use computer components to either combine/make a new component?
As the question asks, I’m just looking for people who have had a project in mind, and used/made components for computers. Like using a router, and making a media adapter. Or anything of that sort.
www.freepctech.com is a good website for free tutorials & great downloads,& great advice.
