How to build a computer

Today in our Blog PC Repair we will give to know how to build a computer from the start. Today to learn how to build a computer can be very important, especially for those who like this job because if he worked as Maintenance and repair of computers in our work will be particularly important to know how to assemble a computer . Among the pieces to assemble a computer or components for assembling a computer include the following: Motherboard, RAM, hard drives, optical drives, CD-ROM, microprocessor, power supply, PCI cards, but are little used lately, and may also have video card games, these are the components for assembling a computer.

Now I need to assemble a computer , well first no need to have a knowledge base of each piece and know that each piece part is located, usually every motherboard comes with a instructions for assembling a computer and so pertectamente know the location of each piece. So we must have the same tools to build a computer such as a screwdriver, the microprocessor ends pasta , although it is a new microprocessor you are installing is not necessary to add thermal paste to the microprocessor . Now the steps to assembling a computer is to leave them below in a video illustrating how to assemble a computer .

I hope you will be very helpful this information and will have good and with this knowledge of how to assemble a computer , if one day decide to buy it piece by piece and with it will know how to assemble a computer .

Testing a Power Supply

Have a power source that you might not know if this working properly and do not knowHow to Prove A power then we will explain here Testing a Power Supply . This test is to verify whether or not a source of power in a computer is good or in poor condition. First of all to Test a Power Supply not need large knowledge in a few simple steps we can check if a power supply is damaged. Likewise to say that sometimes the power supplies are damaged because on the inside have a fuse, this fuse is often burned normally and therefore also have to fail the power supplies feeding the computers . 

To Test A powerwe will need the following: 1. A piece of wire to pass current in both ends of the liner is free with which God protected. 2. A source of power. No more remind you that for this test should not have the font on their computers, this test is made ​​outside the PC, or is not installed on your computer. Steps Testing a Power Supply are the following: 1.Connect the power cord to the power to have power source. 2. With the jumper the green wire and black wire connector 20 or 24 pin power source is connected to the motherboard of the computer. If they see that the fan on the power tour, then we can verify that the power supply is good. I hope you learn this help, and good when you want to prove a source of power and know how.
