The computer doesn t start, and it doesn t respond when you press it

Generally, there is a problem with the power supply!

But it is not ruled out that the memory is troublesome, first unplug the memory and plug it back in. Try to change slots. If it doesn't work, it's a power problem. Try to change and test the power supply first.

It's hard to say! It's best to find someone who knows computers to help you look at it! It could be a hardware issue!

Have you seen that your socket is plugged in? And your power cord is not in good contact! And you open your case!

Plug everything back in! Remember to turn off the power when plugging and unplugging! Then we'll see if it's okay!

Also see if your case's switch key is broken! You press it to see if it bounces up! Sometimes it doesn't pop up but keeps pressing, which is equivalent to a hard shutdown!

good luck!!!

1.Too much dust and poor CPU heat dissipation, causing the CPU to overheat.

2.The memory module is loose.

It is recommended to open the chassis to clean up the dust, unplug the memory module and reinsert it.

You've got a problem with that, too. In fact, there are three possibilities.

1。The power supply is broken.

2.The battery is broken.

3.It's your motherboard that's wrong.

My machine was finally diagnosed as a broken motherboard, but within the warranty period, the manufacturer helped me replace it, and the motherboard was finally fine.

Clean up the dust inside and see if the data and power cables have been gnawed by rats.

In addition, everything that can be removed from the internal hardware is removed and reinstalled.

The main thing is whether the power supply is working properly or not.

Then look at the motherboard.

Finally, look at the memory and graphics card, etc.

Just grab an iron item (such as scissors) and touch the battery on the motherboard. After the warranty.

Just wait and see. I spent the morning on my own.

It is likely to be a power supply problem, if possible, try a different power supply.

That's damp! ～

Let's have a little more time! Just let it dry on its own.

Too much dust and poor CPU heat dissipation, causing the CPU to overheat.

Power supply problems, you can take them to me to fix them. Five pieces at a time.

Open the case and see, the computer shouldn't be left for too long, and so am I, reworked the system.

Hardware failure. Shoot the plan.

1 CPU overheating.

2 Power failure.

See if the power switch contacts are good!

Some part of the computer burned out.

If there is a problem with the power supply, or if there is a problem with the CPU, you can go to the computer city to fix it.

The reasons why the computer suddenly can't turn on and press the power supply and don't respond are as follows:

1. Check whether there is no power connection or the computer has no power, if it is out of power, plug it in and turn it on.

2. Or there is no power on due to a problem with the socket bar, and it cannot be turned on without power.

3. If the socket is normal, then it may be the fault of the computer, go to the maintenance point to overhaul the computer.

4. It may be a circuit problem with the adaptor.

Resolution. 1. Eliminate the power supply problem, plug in the plug, whether the computer fan is rotating, whether the indicator light on the computer case is on, and whether the mouse and keyboard lights are on.

2. Eliminate the problem of the monitor, change the monitor, or press the power button, and listen to whether there is a Windows boot sound while wearing headphones.

3. Eliminate software problems, and after the boot button, wear headphones and listen to whether there is a boot sound of Windows.

4. The last reason is that the motherboard or CPU, or graphics card is broken.

The reason why the computer can't turn on and doesn't respond when you press it is:

1. The source line of the electric fiber is loose, or the power plug-in board is loose, or the plug-in board is not energized.

2. The power supply of the host is broken.

3. The motherboard of the computer is broken.

4. The switch button on the main engine side is broken, or the button is stuck.

A computer (also known as a computer) is an electronic computer used for high-speed computing, which has been called "one of the most advanced scientific and technological inventions of the 20th century". The computer is composed of a hardware system and a software system, which has many functions such as numerical calculation, logical calculation, and storage memory. Its application field has expanded from the initial military scientific research application to all fields of society, leading to technological progress on a global scale.

Software systems include: operating systems, application software, etc. Application software in the computer industry management software, IT computer industry development essential tools, computer industry ERP software.

The hardware system includes: chassis (power supply, hard disk, disk, memory, motherboard, CPU ** processor, CPU fan, optical drive, sound card, network card, graphics card), leak cleaning imitation display, UPS (uninterruptible power supply ** system), keyboard, mouse, etc. (can also be equipped with headphones, microphones, speakers, printers, cameras, etc.). The motherboard of home computers generally has an onboard sound card and a network card.

Some motherboards are equipped with integrated graphics.

According to what you said, it was normal before, even if you change back to the original CPU after changing the CPU, it will not turn on, and if this is the case, the possibility of hardware failure is relatively small.

Nothing happens?! Doesn't the CPU fan turn either? Make sure that the fan power cable is connected to the motherboard, and focus on checking whether the cables and slots are properly and tightly connected, as carelessness or forgetfulness may cause low-level mistakes.

Next, you can try, unplug the main unit, take off the motherboard battery for a few minutes, restore and turn it on.

If it still can't be solved, please explain the three symptoms, whether the power supply fan will turn or not, whether the CPU fan will turn or not, whether there is a display on the screen, and which parts you have moved.

Finally, and the most easily overlooked point, please check whether the CPU and the motherboard slot are connected correctly, especially pay attention to the direction, generally speaking, the CPU and CPU slot have gold triangle markings, in addition, there should be no broken or crooked pins, if so, there can be a pin wrench, generally can still be used normally.

Remove the two wire plugs connected to the boot button on the motherboard, use a screwdriver to short-circuit it to see if it can be turned on, if you can, then change the chassis switch, if not, check whether the 24-pin power plug on the motherboard is plugged in tightly, if there is no problem, it is a problem with the power supply, and it is unlikely that the CPU will be damaged when you replace the CPU.

There's a problem with the motherboard. Detect the power supply of the lower host. Use paper clips to plug in the power supply on both sides and count the fourth, and see if the power supply is working.

The CPU is not compatible with other accessories, and this will happen if it is not, otherwise the driver will be replaced.

There is also the issue of the power supply, which can also happen if the power supply is lower than the power of the computer.

There are many reasons why the computer can't be turned on and the screen doesn't respond, first, the system is damaged, the hard disk is damaged, the notebook can't recognize the hard disk, etc., second, the memory is broken or the memory slot is soldered, and the second is that there is a problem with the motherboard power supply chip.

1.Motherboard + power supply.

2.The motherboard power switch is out of order.

There is a way to do it relatively simple Disassemble the motherboard and put it on a book Remove the power supply Plug in the CPU memory Use the key to find the 2 metal stakes (erected) with the words power on 0ff on the motherboard and short them to see if it starts normally You can judge whether it is a problem with the motherboard, open the cover of the power supply to see if the capacitor on the power supply motherboard is intact If it is intact Short the 42 plug-in grooves on the left and right (close to the side of the transfer buckle) with a return pin to see if the power supply fan rotates You can judge whether the power supply is good or bad.

16 Love is tolerant rather than indulgent Love is caring rather than pampering Love is blending with each other and not unrequited love Love is all kinds of flavors and not all sweetness.

Tired, typing so many words, I hope it helps you.

The CPU can't be changed casually because it's not compatible.
