I dismantled a computer that day and

There are so many possibilities:

Whether the power cord is properly connected (including on the motherboard).

Did the jumper slip out.

Whether the wires connected to the chassis switch are incorrect.

Whether the card position of accessories such as cup is correct.

Clear the BIOS information.

Finally, if there is a smell of burning, if there is, ......

Are you sure you're all pressed? Then see if the interface is plugged in. See if the power is pressed correctly?

Did your brother put static electricity off your body during the process of dismantling your dad's computer???

If you don't let it go, it's likely that you've burned something.

It's dangerous, you have to take a metal object in your hand for 8 seconds, and you can put it in 8 seconds.

My computer has been dismantled n times, and it's still fine, try again.

Your wiring is wrong.

Analysis: If the power supply is reflected when you boot up (as long as there is a light on the whole computer), you will unplug the memory from the plug-in If it doesn't work, plug in the graphics card too, I don't know what interface your hard disk is, if it's pata, then you have to be careful to find the right interface, if it's an IDE, don't plug it in!

Computer hardware generally won't break, as long as you're not a freshly installed machine! Assembling machines are only new machines that are prone to hardware breakage! The hardware of the old machine is very difficult to break!!

Do you mean that after booting, it means that it can be turned on?

Still pressed the power button and didn't reflect at all.

Whether the cable of the power button is connected properly and whether it is plugged in incorrectly. See if everything you can plug in is plugged in.

There is also a problem with the power supply. Try another one.

If there is no mistake, take off the battery on the motherboard first, and then install it after half an hour to see if it can be done.

It's because you're too aggressive, and I hope you don't reverse the memory when you install it.

This is the case with solid state drives, and hard disk drives. The first image is a solid-state hard drive.

1. Most people will choose SSDs to improve the overall speed. However, in the same ** comparison, mechanical hard disks have an advantage in terms of capacity.

2. Structure diagram of mechanical hard disk. It is composed of several parts, such as platter, magnetic head, platter rotating shaft and control motor, magnetic head controller, data converter, interface, cache, etc.

3. Structure diagram of the solid state drive. It is composed of a control unit and a memory unit (flash chip, DRAM chip).

4. Wear and tear of hard disk use.

1. The use time of mechanical hard disk has an advantage.

2. The use time of the SSD is indeed fixed, because the number of writes and reads is certain.

However, the SSD is broken, and it's time for the computer to update! Mean time between failures can be referenced.

5. Shockproof hard disk.

1. Mechanical hard disk is afraid of vibration. Therefore, the hard disk of the laptop will use a very low number of revolutions.

2. The shockproof ability of the SSD is strong!

3. Enterprise-level mechanical hard disk, because it will not be shut down casually, so the number of revolutions will be very high.

6. Summary: 1. Shock resistance and drop resistance: mechanical hard disk is poor, and solid hard has an absolute advantage.

2. Speed: SSDs have a big advantage!

3. Power consumption: The power consumption of SSDs is much lower.

4. Weight and volume: SSDs are low in weight and small in size.

5. Noise: The noise of the SSD is low.

6. The capacity of the SSD is relatively high in the unit**.

7. In data recovery, mechanical hard disk is more secure.

This topic describes the parameters of a disk as an example.

Figure 1 shows a miscellaneous SSD, the interface is SATA, and the transfer speed is 6GB s. There is no identity capacity.

Figure 2 is a Seagate HDD with a capacity of 160GB and 7200 rpm.

Figure 3 is the Western Digital 1TB blue disk, but you are produced in Thailand and sold in Taiwan...

Figure 1: SSD = SSD.

Figure 2 and Figure 3 are HDDs (a Seagate brand, a Western Digital brand).

Solid state drives.

Hard disks. Hard disks.

There is no need to ask such a simple question, there is no point. Elementary school students know what this is, this is an SSD, ** are all hard drives.

The first one is an SSD, which says that a computer with an SSD can increase the speed of the computer.

The second is Seagate's HDD.

The third is the Western Digital HDD.

**1 is a memory module branded as Hynix with a memory capacity of 2GB.

**2 is a hard disk, branded Seagate, with a capacity of 500GB and an interface of SATA.

**3 is a motherboard.

Overall, compared with the current popular standards for the same type of hardware parameters, they are a bit behind. Possible uses:

1. The memory can only be used for old computers.

2. The hard disk can be considered as a mobile hard disk for backup.

3. The motherboard is handled or given to those who need it.

It's okay to use it, keep it for yourself or give it to friends in need, it's best not to throw it away, although these hardware are outdated, it's still okay to assemble a low-configuration computer, you shoot the ** motherboard and the 2G memory card are useful, and you can also sell it to people who collect second-hand computers.

The memory module is not very useful, 2GB is too small. The hard disk can make do with it, 7200 rpm, but it's not much use if it's used for a long time.

Hard disks are still useful, and the inner thick strip of 2G is not popular now.

The motherboard of the notebook basically can't be sold.。。。 Hard disks and memory are still useful.

Figure 1 memory module, but not very useful, only 2G memory.

Figure 2 is the 7200 rpm of the hard disk.

Hard drives, memory modules, graphics cards, and the like.

Visual inspection is a memory module, and the memory module must be inserted into the chassis before the machine can start.

This is the memory module on the motherboard.

I didn't leave you with any computer memory or hard drive.

It should be memory, you see if there is a 1G or 2G word on it.

A memory module, which is a part of a computer that can be bus-addressable and read-write by the CPU. Memory modules used to be an extension of the main memory in the history of personal computers. With the continuous update of computer software and hardware technology, memory modules have become the whole of read and write memory.

When we talk about the size of a computer's memory (RAM), we refer to the total capacity of the memory module.

The data written to RAM (i.e., read-write memory, i.e., memory modules) will disappear completely after the power is off, and the earliest program data that the CPU reads and executes when the computer is turned on comes from ROM (read-only memory). Memory is the basic component of computers (including microcontrollers), and memory has been available since the day computers were available. External memory belongs to computer peripherals, and hard disk is the external memory developed after the stage of tape and floppy disk.

Memory is an essential part of a computer, and the CPU can address it via a data bus. Historically, computer motherboards had main memory, and memory modules were extensions of the main memory. Later computers will not have main memory on the motherboard, and the CPU will rely entirely on memory modules.

All content on external memory must pass through memory in order to function.

The first time to disassemble the computer] the first time to dismantle the computer body:

The first time to dismantle the computer, the first time to dismantle the computer, Shenzhen City, Guangdong Province, Nanshan District, Yucai, a small Kai file three (6) class Liang Zhanpeng, I think I have a good grasp of the software and hardware technology of the computer, but when I disassemble the computer host, I am still a big girl sitting in a sedan chair - the first time, the first time to dismantle the computer. I unplugged the power supply to make sure it was safe before I opened the lid of the case. I looked, oh my God, there's gray on the graphics card, there's gray on the sound card, there's gray ...... on the lineNo wonder your computer is running super slow!

I found a dry and soft cloth to clean up the inside of the host, and I was already sweating at this time, and I was already sweating for the third grade of primary school. Then I removed the graphics card again, checked the chip for damage, and made sure that everything was okay before installing it again. In this way, I carefully checked the important parts of the entire main machine.

After installing the console, I turned on the computer to check the results of my "surgery", but it didn't start. What to do? I can only call ** to my master, Dad.

He asked me to check the case again, and after a lot of effort, I finally found out: the data cable of the motherboard heatsink had forgotten to plug in. I hurriedly plugged it in, alas, and it became a staring jigong!

Although it is very troublesome to disassemble the computer with Kaisun socks, it is worth it! Supervisor: Zhu Hongling Submission:
