Some common mistakes of NO BOOT PC's.
Most of us, neglect some SIMPLE steps how to know if your PC has no booth.
We have encountered this problem and call for a Technician.
To avoid such money giveaways you may try this simple steps to check if your computer is really booting or not.
This are simples step: so called "FIRST AID".
Check the back of your computer. The photo shows the important parts connectors, be sure that the ports and wires are connected at the back of your computer properly.
WIRES - some people neglect to check if the wiring is still in good condition. Some wires become crisp because of the long time service they give to your computer. Be sure to check if the wire is till not crisp or no rat bites.
If your COMPUTER run, but the monitor doesn't show up anything..
CHECK the video Connections.

Types of video connectors
Know the video connectors on your computer and display devices to avoid problems and get the best possible picture quality.
There are two types of video transfer methods: Digital and Analog . If you try to connect a digital connector to an analog port or vise versa, you will not be able to view video. Also, if you attempt to play protected high-definition digital content, such as Blu-ray movies, over an analog connection, you will probably get an error message or the movie will play at lower quality resolutions.
Click the appropriate heading or the accompanying plus (+) sign to expand the following information:
HDMI (digital)
The HDMI connector is a digital connection type for transferring high-definition digital video signals AND audio signals. When used with a compatible monitor or television, HDMI has the capability of carrying true high-definition video and audio as well HDCP protected content (to play Blu-ray high-definition movies). If your computer has HDMI audio, it should be set as the default audio device in Windows audio properties (available from Windows Control Panel). The monitor or TV with HDMI must have speakers to hear audio.

Display Port (digital)
The DisplayPort connector is a digital connection type for sending high-definition digital video signal AND an audio signal to a monitor with a DisplayPort connector. Display has very similar characterics to HDMI but can also support a content protection method called DPCP in addition to the common format HDCP.

DVI (digital/analog)
The DVI connector is a connector for sending a digital video signal to a display device. Use VGA or DVI, but not both at the same time. Some display devices have both a VGA connector and a DVI connector. If your PC supports DVI, try using the VGA for a while and then try using the DVI connection for a while. Then, use the connection that provides the best picture quality for your display device.
DVI-I
Carries both digital and analog signals. If your computer has a DVI-I port, you can connect to any DVI port on a monitor or TV or you can use a wide variety of adapters to connect to other types of ports.
DVI-D
Carries only digital signals. If your computer has a DVI-D port, you can connect to DVI-I or DVD-D ports. You can often connect to other types of digital connections using adapters. Does not connect to a VGA port.
DVI-A Not common. Carries only analog signals. If your computer has a DVI-A port, you can connect to DVI-I or DVD-A ports. You can connect to a VGA port using an adapter. Does not connect to digital ports.

For more information about DVI, see DVI Connections
VGA and SVGA (analog)
The VGA connector is a video connection for sending analog video signals to the monitor or TV. Unless you are planning to connect to a special monitor, such as a plasma or LCD TV that has a DVI connector, connect your Primary monitor using the VGA connector.

S-video and Composite (analog)
The S-video and Composite connectors are used to send an analog video signal to a secondary display device, such as a TV. In some cases it is possible to use these connections for the main display, such as for using a TV as the only monitor for a PC, but doing so is not recommended.
One example of using a secondary display is in a classroom environment; when connecting a video projector to a desktop computer that is already using a monitor, the instructor can use the primary monitor for performing the actions on the computer while students observe the projected image of what the instructor is doing.

7: Composite connector
Connect the speaker and microphone cable, if those connections are available on the display device. Some display devices may have built-in speakers or a microphone. Connect these cables to the computer.
Connect the power cord to the display device and a power source.
CAUTION: HP recommends connecting the monitor or TV to a surge protection device as the power source to prevent damage to the monitor or TV if a power spike occurs.
After checking if the connectors are connected properly,
Check the plugs.
And lastly...
If you see the PLUG and Socket like this, please make sure that you give pay attention. This is dangerous..
Some common mistakes --
urghh!! My pc won't boot!! --09222222....- -'Hello Mr. Tech, my pc is not booting, please come quick!!'
afterwards-- the Tech found out that the plug and socket are not connected properly-- it's called... EPIC neglecting.
Thanks for bubbling with me!
