Ask for help for machine failure, how to avoid machine failure

After reinstalling the system, see if there is still such a problem. If anything, it's a hardware issue. The hardware that is related to this problem are: power supply, memory, graphics card, fan. If there is no alarm on the host, it is not a problem with the memory and graphics card!

Look at the CPU, graphics card fan to see if it moves? If you can't move, you must replace it. If it moves, it's your power problem, and if your home's electricity is unstable, you add a UPS and you'll be fine.

UPS can help you stabilize your power. If your home's electricity is stable, it's your power supply is broken. Change the power supply and you'll be fine!

Generally, if there is something wrong with the memory and graphics card, the computer will definitely be alarmed if it restarts! Hopefully, your PC isn't a hardware issue. If so, check it out the way I do.

But if you have a computer problem for me to see. The power supply is broken, and it is relatively large.

It is recommended that you reinstall the system. If you can't reinstall the hard drive, check it.

You should look at your machine's memory and graphics card and CPU

You should clean up your computer regularly.

In one of the things is that you should kill the virus regularly.

It may be that the hard disk is broken, you can check it with the efficiency source.

Disassemble the hardware and reassemble it.

Let's see if the CPU fan is not working well!

Or the case is not well ventilated, caused by too high a temperature.

This is one of the possibilities and the biggest suspicious point.

Should you test whether your power supply can have enough power to support it?

Don't know if there is a machine alarm?

If there is an alarm, you can check the information about the BIOS alarm. If not, in this case, I guess there may be something wrong with the board as well.

Something burned out, look at the memory, the battery, and the graphics card, etc...

First: Insert the board (memory, graphics card) again! Rub with phase skin. Rub it off.

Second: see if the CPU temperature is normal.

It could be that the battery on your motherboard has burst.

Hehe, you plug the memory back in.

1. Cleaning to be done before shutting down every day.

Double-click "My Computer" - right-click on the C drive - click "Properties" - click "Disk Cleanup" - click "OK" - click "Yes" - click "OK" again.

During the cleaning process, you can see that the "temporary files" that came in without your permission (you can click "View Files" to see, you will know) have been cleared, and the disk space is more. This method is also used for D, E, and F disks.

2. Clean-up to be carried out at any time.

Open the webpage - click "Tools" in the top row - click "Internet Options" - click "Delete Files" in the middle of "Temporary Internet Files" - then tick the box before "Delete all offline content" - click "OK" - click "OK" after clearing.

This speeds up the opening of web pages and spaces.

3. Garbage removal of the tray carried out in a week.

Click "Start" - point to "All Programs" with the mouse, then "Accessories", then "System Tools" - click "Disk Defragmenter" - click on C drive, then "Defragment" (this takes a long time, and is best done when you go to dinner and don't use your computer.) You can see the condition of your plate during the cleanup, and you can compare the before and after cleaning) - click "Close" after the "Cleaning Completed" pop-up.

According to the above method, the D, E, and F disks are cleaned separately.

There is another trick: speed up the bandwidth, and learn to release 20% of the broadband resources reserved by the computer in a minute.

1. Click "Start - Run", enter enter enter to open the "Group Policy Object".

2. "Computer Configuration - Management Template - Network - QoS Packet Scheduler", double-click "Limit Reservable Bandwidth" in the right setting bar, set "Limit Reservable Bandwidth" to "Enabled" in the "Settings" tab in the properties dialog box that opens, and then set the bandwidth value "20" to "0" in the "Bandwidth Limit ( ) column below".

4. This change is valid for both XP and VISTA.

Usually do a good job of maintenance, do not have too much dust, the voltage is stable and normal.

There are many factors:

1. Hardware electronic components are burned, broken down or aging and lose their function, which will cause damage to the motherboard, graphics card, and memory module, resulting in failure to boot or error.

2. Due to the long-term work of the gold finger, there will be an oxide layer, resulting in poor contact, memory module alarm, graphics card alarm, and CPU alarm.

3. The cooling fan does not work properly, resulting in excessive heat in the machine, resulting in a crash.

4. Too much dust in the machine and poor heat dissipation, resulting in crash or slow operation.

You must first report to the boss and inform the delivery date of this batch of goods and the possible consequences of overdue. Then go to your customer to understand the situation, explain the situation of your own business, and see if you can strive for late delivery, or delivery in installments, and get the user's understanding as much as possible.

The answer CA, "unthinkable", is not true. b. "for" should be "right"; "Question" could be deleted; The phrase "great contradiction" is inaccurate. d. Ambiguity.

The external reasons for the failure of mechanical equipment mainly include: environmental reasons, such as dust, abrasive particles, temperature, pressure, corrosion, climate and other factors; Reasons for equipment load, such as load exceeding design capacity, uneven load, short-term load exceeding design value, etc.; Installation and commissioning problems, such as improper installation and commissioning or failure to meet design requirements. Failure to maintain and operate the equipment as required, such as poor lubrication, sealing problems, failure to test and run in accordance with the requirements in the early stage of equipment use, and incorrect operation of post workers; Improper last overhaul, such as substandard parts replaced or repaired, assembly problems, etc.

The main internal reasons are: there are problems in the design of the machinery itself, and the manufacturing quality of the parts is not up to standard.

Causes of mechanical equipment failures.

Experience: 1The reason for the failure of the belt drive is that the force of the belt acting on the shaft is large, and the long-distance transmission is realized, and the belt is worn, torn or even broken for a long time, which has a greater impact on the bearing.

2.The main causes of gear transmission failure are tooth wear and pitting corrosion caused by poor lubrication working environment. The tooth surface meshing is not in place, resulting in tooth root breakage, plastic deformation and so on. Too much.

3.Chain drive, mainly due to poor lubrication working environment caused by chain sleeve wear, too much, can you ask targeted questions?

Causes of mechanical failure: It is caused by wear and heat.

1) If it is a problem with the broadband itself, first directly connect the broadband network cable to test, if it is a broadband problem, contact the broadband customer service to solve it.

2) If it's a problem with the router, if it can be used originally, it can't be used for the time being, my own practice is to disconnect the power of the router and plug it in, and I'll take a look. After there is a factory reset, it can be used from the new settings (this is under the premise that the physical mountain Luzi connection is correct, sometimes it is caused by the router finding IP address slow or failed, not that the router is broken).

If it can't be solved all the time, it is recommended to call the customer service of the router**, they have **** guidance, I encounter a problem that I can't solve by myself, it is very useful to consult them for advice on the way to the min, and they will give the correct advice for your settings or operations.

3) If you turn off the wireless switch, turn it on, if it is a wireless connection with software, it is normal for the software to be difficult to use and often have problems, there is no better way, use a router. In addition, it is caused by the network card driver is not or is not suitable, and whether there is a problem with the network cable interface or network cable.

4) If it is caused by a system problem, it is recommended to restore the system or reinstall it.

1)**Google and other browsers to test, if it is easy to use, see**, on**, oo space, or browse other web pages when using this software, these are not using IE as the kernel, and you use IE does not conflict (sometimes it is caused by the browser is not easy to use, I picked it out from multiple browsers in practice, this browser is very famous, because it is not easy to crash, because each web page problem will not affect the entire browser, if you have a problem, please ask me).

If it's caused by a network issue:

2) A Hui group is generally a network, there is a problem with the router when there is a quarrel, you see if the IP and other settings are appropriate, and you don't use the router to try, or unplug the router power and plug it in, or restart the router to try. There is also a problem with the ** and browser that you are on, and sometimes the browser wants to clean up the temporary files. Such a problem,Most likely** itself is a problem.,The browser is not suitable for this network or which station.,And it's time to open this** or QQ space.,Don't open other programs.,For example:
