New computer does not turn on after assembly. The computer does not turn on when turned on, consider why

So you have acquired new computer and ready to get started. When all the components of the computer are nearby, not connected to each other, a bunch of different wires around, it may seem that you cannot cope with this task. There is really no reason to panic. The first launch of the computer will take place as planned.

In most cases, a small manual on how to connect it comes with the computer. But, even if there is no such instruction, you can still put everything together yourself in just a few simple steps.

Preparing to launch the laptop

If you bought laptop or netbook, then the preparation procedure before the first launch will take less than a minute. On some models, it may be necessary to connect the battery. When the battery is in place, open the cover and press the power button. If the battery is not charged, you will need to connect aC adapterthat comes with the laptop. You can continue to work while charging.

If you need to connect to a laptop peripherals, see the instructions below, desktop and laptop computers generally use the same connection types.

Preparing to launch a desktop computer

Step 1

Unpack monitor, system unit, keyboard and other computer components from the box. Remove all transport, plastic or protective films. Install the monitor and the system unit at the workplace.

Installation recommendations: Place the system unit so that there is sufficient space for air circulation to avoid overheating. It is best to position the monitor so that the light source is to the left of the monitor to avoid glare.

Step 2

Take monitor cable... The monitor always comes with two cables, one for connecting to the mains, the other for connecting to a computer (system unit). Depending on the monitor model, a VGA, DVI or HDMI cable may be included. VGA cable is often blue colour on chips connectors to make them easier to identify. If you bought monoblock, you can go to Step 4.

Step 3

Connect one end of the cable to monitor, you won't be mistaken with the choice of the port, and the other end to the same port on the back of the system unit... Be careful and careful, the connectors and jacks of the ports have a geometric shape, with the correct connection, no effort is required. If your cable has screws, tighten them lightly to secure the contact.

Advice: if the cable does not "go", do not shove it, or you may damage the connectors. Make sure the connector on the cable matches the connector on your computer, then plug it in.

Step 4

Take keyboard USB PS / 2 (purple round connector).

If using a USB connector, connect it to any of the USB ports on the back of your computer. If using a PS / 2 connector, connect it to purple

Step 5

Take mouse and determine which connector it connects to the computer. It could be USB (rectangular connector in white or black) or PS / 2 (round green connector). If your mouse has a USB connector, plug it into any of the free USB ports on the back of your computer. If using a PS / 2 connector, connect it to green round port on the back of the computer.

If your keyboard has USB port, you can connect the mouse to the keyboard instead of directly connecting to the computer. Or you can connect a USB flashlight to this port to illuminate the keyboard and desktop. And also the presence of a USB port is convenient when connecting a "flash drive", no need to look for a connector on a computer, everything is at hand.

If you have wireless mouse or keyboard may need to connect bluetooth adapter (USB adapter) included with the wireless device.

Step 6

if you have speakers or headphones, you can connect them to your computer at audio port (on the front or rear panel of the system unit). These ports are different colors, as are the plugs for the connection. Loudspeakers or headphones connect to green port, microphone connects to pink (red) port. You can't go wrong with the color of the plug. Blue port to be used with other types of devices.

Some speakers, headphones, and microphones have uSB connectors instead of the usual audio jack. They can be plugged into any USB port. In addition, some monitors have built-in speakers and a microphone, they will also need to be connected to the system unit. For this, the same colored connectors are used.

Step 7

Take two power cablesupplied with your computer and monitor. Connect the first power cable to the rear panel system unitthen in network filter... Then, using a different cable, connect monitor to surge protector.

Step 8

Finally, connect network filter into an outlet. You may also need to include network filter it has a power switch.

Building a computer is fun. Plus, it saves budget. You kind of hire yourself to build a computer and pay yourself 10-15 thousand rubles. (when assembling a gaming PC relative to the store price).

Assembling a computer yourself is not a tricky business. Of the tools, only a Phillips screwdriver is needed. But what to do next when all the parts are screwed into place? What to do after assembling the system unit? How to start the computer after assembly? How is BIOS setup for installing Windows 7 on an SSD? How is Windows installed after assembling the computer?

At first glance, there are a lot of questions and you can get confused from surprise. But the good news is that the days when only professionals could figure this out are long gone. Today, almost all of this work is automated. And if you follow a certain sequence of actions, then any person with a technical mindset can figure it out.

Let's take a look at the first power-up of a newly assembled computer using a popular budget configuration for gaming (gaming computer) and RAW photo processing (photography computer) as an example. The article will also be of interest to those who are looking for answers to the questions: "How to start the computer after replacing the motherboard?" or "How do I start my computer after replacing the hard drive?" Since Bios is on the motherboard, and Windows is installed on a hard drive or solid-state SSD.

So, we have a system on the following components (which I assembled):

  • INTEL Core i5 6500 processor, LGA 1151 BOX;
  • Motherboard MSI H110M PRO-VD LGA 1151, mATX, Ret;
  • RAM Kingston HyperX FURY Black Series 16 GB;
  • SSD OCZ Trion 150 TRN150-25SAT3-240G 240GB, 2.5 ″, SATA III;
  • 1 TB WD Caviar Blue hard drive;
  • DVD-RW Optical Drive LG GH24NSD0, Internal, SATA, Black, OEM.

The specified configuration is enough for processing photos (using the integrated graphics core Intel HD Graphics 530). In order for the computer to become super gaming, you need to add a video card to your wallet. The best option would be the GeForce GTX 10 series. But the presence of a video card does not have any effect on the first start-up of the computer.

We will install the operating system on an SSD, and set aside the hard disk for storing various files. Therefore, it is very important that the hard drive is disconnected from the motherboard when first powered on. Then the system will automatically configure many parameters to work on the solid-state SSD. We will connect the hard drive and tighten it up later, using the means of the already installed Windows. This is a standard procedure and is straightforward.

In general, the first start-up of a computer after assembly consists of the following steps:

  • bIOS setup and firmware update (if necessary);
  • installation of the Operating System;
  • installation of drivers for incoming components;
  • software installation.

So, the computer is assembled, we proceed to setting up the BIOS.

Configuring BIOS msi h110m pro-vd UEFI for installing Windows 7

When you turn on the computer, the first thing you need to pay attention to is that the fans started spinning: on the processor and on the case of the system unit, the lights on the front panel blinked, the monitor came to life. These are the first signs that things are going well.

The appearance and location of the BIOS menu depends on the manufacturer of the motherboard (motherboard). In this case, we are dealing with MSI UEFI. To get into this utility, you need to press the DELETE key on the keyboard when turning on the computer.

If all wires and components are in place, you will see the first Bios tab called SYSTEM STATE. If there is nothing on the monitor, you need to check all connectors for tightness or look for a faulty component. You need to dig into the electronics of the system unit when the power is off. In addition, the h110m pro-vd board has 3 LEDs that light up every time the system starts up if there are problems with the processor, RAM and video card.


System State: Checking Discovered Devices

Setting up BIOS msi for installing Windows 7, as well as for Windows 8.1 or 10, begins with the fact that in the first line of SYSTEM LANGUAGE you need to select Russian. Then the interface will become Russian. Then you can set the system date and time. But you can leave it as it is, because the first time you access the Internet, the computer will set the correct date and time. Below you need to check that the computer sees all your SATA devices. In this case, you can see two connected devices (as it should be):

  • SATA Port 1: Solid State SSD: Toshiba-TR150;
  • SATA port 2: None (disconnected hard drive);
  • SATA port 3: DVD drive: HL-DT-ST DVD-RA ATAPI;
  • SATA port 4: None (free connector).

For the first time I didn't have an optical drive on the list. I turned off the computer and checked the drive connector - it was not fully inserted. Having sunk the connector another 3-4 mm all the way, I turned on the computer again. The optical drive was now in place.

The PHYSICAL MEMORY line contains 16384 MB, which means that all memory has been identified. The MEMORY SPEED line contains 2133 MHz - the memory operates at the declared frequency.

Nothing else interests us especially here. Then you can walk through all the tabs to see what is there. Find the screen with CPU temperatures. It is important that the temperature is within normal limits. For the i5-6500, the maximum temperature is 71 ° C. This is under load. And at idle, somewhere between 30-40 ° C. And then suddenly you have poor contact between the processor and fan. Then you will need to check the quality of the installation of the processor cooler.

We pass to the second tab ADDITIONAL. We select the BUILT-IN PERIPHERAL DEVICES there and see that the mode is in the SATA line. This setting is needed when installing Windows on a solid state SSD drive.


Checking whether AHCI mode is enabled when installing Windows on an SSD

In the same ADDITIONAL tab, in the WINDOWS OS CONFIGURATION window, switch for WINDOWS 7 INSTALLATION to ON. If you install Windows 8.1 or 10, select the item of the same name on this screen.


Selecting the installation option for Windows 7 or 8.1 (10)

Go to the 6th boot tab (BOOT). In the picture, everything is written in English, because English is selected on the 1st tab, I specifically did this to show how the English version of the BIOS interface looks like. Here it is important to set the options for the boot queue, that is, in what sequence the devices will be polled for boot files. This is the bios setup for installing windows 7 (8 or 10) either from a disk, or from a flash drive, or from a usb. I put up the classic scheme: first, the DVD drive is checked, then the solid-state SSD drive. We will be installing Windows 7 from a DVD, so the built-in DVD drive is first in line. After installing Windows, we will remove the installation disc from the drive. The computer will check the DVD drive, find no boot files there and go to the second device: a solid-state drive, on which Windows will already be installed, so the operating system will boot. With this scheme, it is not even necessary to disable boot from DVD in BIOS after installing the OS. Everything will work anyway.

If your OS will be installed from a USB flash drive or from an external DVD drive connected via usb, then the first in the boot queue should be selected the appropriate USB device instead of the built-in DVD drive.


Configuring bios for installing windows 7 from disk

Next, go to the last SAVE & EXIT tab, save the settings and exit the BIOS. But before exiting the BIOS, you need to open the DVD drive and insert the Windows 7 installation disc into the drive, since we cannot do this on a turned off computer, and we need the disc to get into the drive before the next computer is turned on. It is not necessary to slide the drive in as it will slide in automatically after turning on the computer.

You are now ready to install Windows 7 on your computer. Read how to do this in the next, assembled by yourself.

Once they gave me an internship with a young man who was very fond of computers, but absolutely did not understand them. At first, I tried to find out his skill level for system administration. Faced with deathly silence, I had to ask him questions about the "hardware". The result was the same. Then I could no longer resist and asked a question about how he would act if the computer did not start. The answer still amuses me. “To do this, you need to call a computer technician,” my intern answered.

Despite the abundance of information on the Internet, more and more often I am bombarded with questions by both novice computer assemblers and those who already have solid experience. Alas, substandard components are often imported to Russia, which affects the assembly results. However, let's take a look at the main causes of PC inoperability. By the way, this algorithm is also suitable for detecting computer malfunctions.

So, you have an assembled computer and you, freezing with delight, press the Power button and look in frustration at a blank screen. This situation is quite common, although I myself have come across it only once. Let's now see how we can start the iron friend:

1.If the computer starts up (the fans are noisy or the speaker beeps), then go to the next steps. If not, read this section carefully. There can be only a few reasons for a launch failure. Either the computer's power supply is defective, or you simply plugged the power button terminals incorrectly. In some cases, the motherboard may be faulty. I don’t think that you are experts in the field of electronics, otherwise you simply wouldn’t read this article. Therefore, I will leave questions about repairing motherboards (and there can be a lot of reasons, ranging from swollen capacitors, faulty transistors, etc. to dead chipsets). However, the factor of a faulty motherboard cannot be overlooked. If you have a normal motherboard, then there is always a power indicator. It perfectly eliminates the malfunction of the power supply. The latter can be checked either on another computer or using a multimeter (tester). However, I myself have acquired a tester relatively recently, but I have no problems with additional computers. Power supply defective? Change and that's it. If the power supply is in order, then try to start your computer by shorting the PWD SW pins on the motherboard with a flat screwdriver, having previously disconnected the button connector. The PWD SW pins are located in the pin group at the front (usually on the left) of the motherboard. Often, the contacts are color-coded, in which case look for a green (light green) color. This will make it start. If this did not work for you, then remove the battery from the motherboard and put a coin in its place. This will remove the residual charge and reset the BIOS settings to factory defaults. If this does not work, then remove the motherboard from the case and run your filling on the table. I came across cases that closed the motherboard. Well, if this did not help, then you will have to accept the fate and bear the fee to the service center. At home, you will not do anything with it.

2. However, the computer most often starts up, but the monitor screen remains blank. And here there can be a lot of reasons. It could also be a faulty processor. It may even be incorrectly inserted into the slot. The RAM may not be fully inserted into the slot, or it may be faulty. All of these problems are easy to spot yourself. For these purposes, professionals have special devices called POST cards. They read data from the BIOS and give out signal information, by which a malfunction can be determined. Good thing, but if you don't build computers on an industrial scale, then you don't need it. Often your assistant is a speaker on the case or motherboard. Let me tell you a little secret - the computer diagnoses itself already at the startup stage, reporting the signals of this diagnosis to the speaker. Having piked once, the BIOS reports that the system is working normally and there are no problems. But multiple signals indicate various problems. However, the speaker may be completely silent. Sometimes this is due to the fact that it is simply not connected, but more often it is something with the hardware. In this case, remove the cooler on the processor, start the computer and turn it off after a couple of minutes. Place your fingers on the processor. If its surface is warm, then everything is fine with it. If not, make sure you remember to connect the 4-pin 12 volt plug from the power supply to the motherboard. It is easy to distinguish it - the four wires on it will have black and yellow markings. If connected, remove the processor and reinstall it in the socket. Try to start. In any case, it is important for us that it is warm.

And if the processor is warm, the speaker does not beep, and the fans spin. Then you need to knock down the BIOS in the way described in paragraph 1. Be sure to knock down the charge with a coin !.

I always tell my clients that if the computer beeps, then it is very good. Despite the variety of bios (and now UEFI), they still have some common features. So, for example, I have always come across motherboards that reported two signals about problems with RAM. If something like this happened to you, then pull the memory sticks out of the slots and wipe their contacts with an eraser, and then insert them back. If the signals persist, then the memory is faulty. We'll have to change.

Three beeps may indicate a problem with the graphics system. Most modern motherboards come with a built-in video output (or the graphics are integrated into the motherboard or processor, for example, from Intel). If you have an external video card, remove it and connect the monitor to the integrated video. The problem is resolved? Okay, throw your graphics card away. But what about those who don't have a built-in video core? Pull out the video card and wipe the contacts with an eraser and insert into place. Do you get an image? If not, then you need to go to the service and check the video card there. Sometimes the problem may not be with the video card. So, for example, I came across an Asus motherboard, where the PCI-Express bus failed due to a burnt-out transistor. However, this case is rather exceptional.

Well, if everything started up for you, but the BIOS does not see the hard drive, check that all the loops are connected to it correctly.

It is very easy to fix computer problems. Thanks to the block architecture, even a schoolchild can carry out repairs. Hope I helped you with this article.
