A Diy Guide To Hardware Computer Repair And Periodic Maintenance
Sep 7th
Performing hardware computer repair and periodic maintenance is a sure way to keep a PC running smooth for years. The methods involved in this process include cleaning the system, replacing any parts that fail and creating a routine to provide upkeep on a regular basis. Some of the components that can fail include memory, hard drives, video cards, motherboards and case fans.
Internal components are known to last for a very long time if properly maintained and this means regular cleanings. Another way of maintaining a PC is keeping the hard drives defragmented by using the tools available in the operating system. Keeping the hard drive maintained will reduce the chances of it failing and causing repairs to be necessary.
Prior to performing any repairs remember to unplug the power from the system first before opening it. Memory is very easy to replace and can be done by following a few easy steps. To remove the memory press down on the clips on either end to release the module and pull it free, next take it to an electronics store to get a replacement.
If a hard drive fails, removing it is quite easy and is done by using a Philips head screwdriver. The first step is to open the case and unplug the power plug and drive cable by gently wiggling them free. If it is a newer desktop then the cables may be a bit different and are released by pushing a tab. Once power wires and cables are removed, use the screwdriver to remove the screws holding the drive and pull it free.
DDR SDRAM Computer Hardware Guide
Jul 6th
DDR SDRAM stands for double data rate synchronous dynamic random access memory. It is a type of memory that is used in computer to help it accomplish tasks in twice the amount of speed as the old regular SDRAM chips of yesteryear.
Most DDR SDRAM chips have model numbers that match their speed. For example a PC-1600 chip transfers data at 1600 MB/s. A PC-3200 chip would then transfer data at 3200 MB/s which is the top speed of DDR memory.
These newer chips can hold up to 1 Gigabyte of RAM on one chip. Most motherboards have room for 2 or 3 RAM chips which means that you could have up to 3 Gigabytes of SDRAM in your computer which would really help with overall speed.
SDRAM is mainly used for the temporary processes and commands a computer goes through. We don’t realize how much a computer temporarily stores, so let us help give you an idea.
For example, say you open up your e-mail. The computer first loads internet explorer, than opens of the web page, and sits there temporarily while you write your email until it send it. While it’s “waiting” it has pushed all those previous processes to it’s RAM to remember so that when it is ready to send it can just quickly pull that back up out of the ram and send the e-mail. From this example you can see how bogged down a computer can get when a person is playing a game while reading their e-mail and using Photoshop to edit pictures.
