Why does a newly assembled computer sometimes fail to turn on?

In my estimation, it should be a multifaceted problem. First of all, check whether the voltage of the computer is sufficient when it is used? Is it the peak time for electricity consumption?

Is there a problem with the power supply? Secondly, check whether the various boards inside the chassis are accurately and stably fixed. Finally, if the above problems do not occur, then I think the board is not compatible with the display, or it is not very compatible.

It is recommended that you check according to the above steps, if it doesn't work, you have to return it. Hope mine can help you! Beg.

You first distinguish the situation, if you can't turn on the machine at all, that is, there is no response at all after pressing the start button, that is, there is a problem with your CPU, memory or motherboard, the solution is to find a matching machine that works normally, for example, Ben 3 will find Ben 3, Ben 4 will find Ben 4. Then try to replace it with hardware, first try the power supply, then the motherboard, memory, CPU, then the hard disk and then various boards, you can find out what is wrong with the hardware, and then replace it. If your machine still has a response when you press the start button, but there is no corresponding sound except for a few alarm beeps, then you can count a few sounds, and then find the corresponding motherboard manual to check what the problem is.

And the motherboard manual will tell you in detail what problems and how to solve them. If you have a boot and self-test screen but can't get into the system, then you may have a problem with your system. Redo the system, if you're using Windows, it's a common thing.

Because of the habit, but if you are a genuine user can call their customer service, scold them and ask them how to solve it, hehe, relieve anger. If it's self-checking, but it may be a problem with a board, such as a sound card, or a network card or something, then you unplug all the plug-ins except for the memory and CPU, and then only hang the hard disk to try, if you can pass, then you will try one by one, because you should be able to find the problem board, if you can occasionally enter the system, most of the time but can't get in, it may be that your board is not well inserted, you plug it in one by one. If it's still like this, then you can change the battery of the motherboard and try it, if it still doesn't work, then change to a good motherboard and try it, if all else doesn't work, then you either continue to try, or find a professional repair place to repair it, or change it to a new one Good luck!

In fact, you can buy a hard disk directly on the Internet to make a good system, and you can turn it on directly.

There are many reasons why the computer can not be turned on, sometimes it is just an independent problem, sometimes it can also be caused by various factors, first check whether the power supply part of the computer is faulty, and then check the hard disk and motherboard, of course, the graphics card is damaged or mismatched can also be photographed as not turned on, so they must be checked one by one to really solve the problem.

Check whether the host is good, whether the motherboard indicator is on, whether the graphics card and memory are plugged in firmly, and whether the monitor is well wired.

It's best to find someone who knows.

It can be turned on, but it cannot enter the desktop.

You must enter the DOS to install the operating system on the computer to use it normally.

Building a computer is also called a compatible machine or DIY computer.

That is, according to personal needs, select the accessories needed for the computer, and then assemble various non-conflicting accessories together, which becomes an assembled computer. The accessories used to assemble a computer generally include: CPU, motherboard, memory, graphics card, hard disk, optical drive, monitor, chassis, power supply, keyboard and mouse.

Assembling a computer is generally a desktop, and laptops are usually rarely assembled by themselves. The ** of assembling a computer is generally lower than that of a branded computer, but the quality is not necessarily guaranteed. Because it is assembled, the accessories may be fake, parallel import, or second-hand, and a certain amount of expertise is required when purchasing, as well as considering whether each piece of hardware is reasonable.

There is no system that can be turned on, but because there is no system. , so you can't get into the system, desktop, etc., and there is no point in not having a system.

Of course, it's okay to boot up, but it can't be used without an operating system.

1.It can be turned on, but it cannot enter the system.

Just plug the USB flash drive directly into it, and it will read it automatically.

You can't turn on the machine without the system, the system is software, only the hardware can't be turned on without software!

Assemble the computer Generally, the merchant will make a system for you, which is a free service ghost version of the 10 minutes soon.

If you are a pure novice, you have never done the system, it is recommended that you find someone to do this thing, when you first learn it, there is too much trouble, and it is a waste of tongue.

Of course, if you have a research spirit, if you just want to use it, find someone to do it.

If you can't enter the system, you can find someone to help you install it, just 5 yuan.

No, absolutely not.
