Install Power Supply

It's possible that our power supply of computer at some point ceased to produce electricity and doesn't turn on. Here he explains how to change by a new and help you understand what type of connectors and where we can connect.

First a pictures from a typical power supply and differents connectors.





The first two we see are the connectors that connect to motherboard (usually ATX, or 20 pins),
IDE and Floppy connectors (and almost dying giving way to sata) were used and are still used to connect IDE hard drives or floppy disk drives, next sata connector pin for connecting SATA drives (faster than the IDE) and and finally the PCI Express connector this is mostly used to connect most new graphics cards.

Knowing that is a power supply connectors and knowing we can change:

1-. Remove the box and extract the old power supply to enter the new one. Consult your manual to see if the board support it.

2-. Connect 20-pin cable to the motherboard. (Assuming that the motherboard is relatively new)

3-. Plug in the power connectors to CPU and the CPU fan or fans.

4-. Now, we must connect the power connector to the storage units, power switch, reset switch, led's.

5-. And finally, if you have a floppy drive connect it.

6-. Turn on computer and test if all are working good.

How to mount a motherboard into ATX case

Here I will show a video explaining how to mount a motherboard into a standard ATX case, I think it's fairly clear understanding.

Upgrading the Memory

Surely ever notice how our computer isn't working as fast as usual because too many programs installed, or because the system requirements will naturally increase.

First let's decide how much we want to install new memory in the computer though, once we have thought that buying a new memory module (you can choose from 128MB to 2GB).

I will explain the procedure so that it points more clearly to understand:

1-. Turn off our computer and unplugged,

2-. Open the chassis using the rear screws.

3-. We look for the part of the motherboard where the memory.

4-. Push the two white tabs to remove the current memory and pull out the chip.

5-. Carefully introduce the new chip and press until you hear a sound (cleeck)

6-. Make sure you are well placed and turned on our computer again.

That's all. Here I'll show a video explaining better this.

Change the Battery CMOS

The computers have a battery on a chip (CMOS) which contains settings that make the clock run after being shut down.

If your computer has problems with dates or time, ie every time you boot you need to configure these settings by hand, then you change the battery. Here I will explain you how to do this:

1-. First of all we must keep in a safe settings of our system, therefore, we must start the computer and access the bios to take note of each one.

2-. Turn off the computer and remove case.

3-. Before moving to action, now we must identify the type of battery that uses our motherboard (lithium batteries, alkaline or built-in batteries with connector).

4-. When you know what type of battery used our plate, we can then remove the old and the new place (remember that position was previously installed).

5-. Mount again case, plugged in and turn on the computer.

6-. Now, you can change the date and time.

Understanding risks of overclocking

Makes overclocking the cpu to work beyond their technical specifications and that means some things to consider before implementing it.

Firstly and I think the most important is the fact that if we overclock our CPU to lose their garantee and technical support in the event that one day stop working.

The purpose of overclocking is to make the chip work faster if i like electrical component operates on a higher frequency will also be hot if they work in normal mode. The heat that follows a long-term potential to damage some components and shorten its life. Joule's Law said P = V * I where P is the heat dissipated by the CPU, the V is the voltage and finally I is the intensity or current required by the microprocessor to work. Likewise, if the voltage increases (overclock) and in the same way electricity is a higher wattage, the greater intensity and higher temperature.

If you want to know more can search on google the effect of electromigration.

In the same way if no overclocking is done with caution at all times and knowing what they are doing this may cause unexpected problems such as faulty electrical signals, reboots or simply the operating system crashes.

System Beeps

Sometimes, during the execution of the POST (power-on-self-test), our computer may not achieve "approved." If the result it's positive the motherboard beeps short line everything is ok, however if POST find any error or failure tell us differently with different types of beep. I give you a link in which explain in detail what mean that each of these beeps.
