Ask Computer Oddities to see what is wrong with computers.

Partition reload. Solve it in one go.

If the computer is nothing important, it is recommended to reinstall it.

I speculate on the possible reasons (if you are not very professional, please forgive me).

1.Hardware problems: As my friend said, it is very likely that dust is causing the instability of the machine.

2.Medium computer virus: It is recommended to use professional anti-virus software (such as Kaba, Norton) for comprehensive anti-virus.

3.Some kind of conflict may occur - right-click on "Computer" ("My Computer" for XP systems) - Administration - Event Viewer: Look carefully at the records in the "Windows Log" and look for solutions to the error messages recorded when your PC freezes on the web.

I don't think it's the startup items or general system services that cause your crash, the reason: you have been on for at least a while when the crash occurs, and if the problem is caused by these factors, it should have happened long ago and would not have lasted that long.

It feels like your computer configuration can't bring this system, and it can't be buffered

Reload the system disk! Don't load too much software later.

You know a lot. Hehe, your computer is poisoned.

Radically abolish the Trojan function:

Method: Run to open your registry, which has a directory tree:

hkey local machine sam sam domains account groups, well, this group is responsible for establishing users. (Note that you need to back up your groups before proceeding to the next step, and you can restore them if necessary.) Delete it, and the system won't be able to create users.

No matter how much the Trojan tries, it will not be able to establish users, let alone be promoted to administrators. If the files in this directory are deleted, there is no way to restore them.

Backup method: Right-click on the groups and select "Export", give the exported file a name, save it, and you're good to go.

It's better that you're redoing a system! Are you looking at how dusty the computer is??

It may be a virus, and it is recommended to reinstall the system.

If you have backed up the data,You can try to restore the system,If it still doesn't work,Buy a win7 ultimate version of the 64 disc reinstallation can be basically solved,Remember to backup information,Especially on the desktop,And C disk,Quick can not be!

1.Poor heat dissipation, power failure, and motherboard failure may cause the computer to shut down automatically or restart repeatedly. (Reboot is an important feature: sometimes it shuts down, sometimes it restarts).

2.When the core components of the system are damaged, the running computer may automatically shut down. Kingsoft security experts are here to provide you with special killing tools and system repair tools, please click Fast**.

3.In the running software, there are some software with the option to shut down when the task is completed, and the user may not have noticed and turned these switches on.

These software are more common, such as Thunderbolt, Express, anti-virus software, BT**, **** and so on. In the software settings, there is an action that automatically shuts down after completing a certain task. But generally the default setting is off.

The purpose is to automatically shut down the computer when a task is completed when a task is running a more time-consuming operation.

4.Other hardware reasons.

Faulty power supply or motherboard.

Inaccurate mouse positioning.

The fault is manifested as the uncertain position of the mouse or the drift often occurs for no reason, and the main reasons for the failure are:

1) The influence of stray light from the outside world. Nowadays, some mice in order to pursue a beautiful and beautiful shell of the touluminous performance is too good, if the optical path shielding is not good, coupled with the surrounding strong light interference, it is easy to affect the transmission of the internal optical signal of the mouse, and the resulting interference pulse will cause the mouse to malfunction.

2) If there is virtual soldering in the circuit, the pulse generated by the circuit will be mixed and cause interference, which will affect the normal operation of the circuit. In this case, it is necessary to carefully inspect the solder joints of the circuit, especially some parts that are susceptible to stress. After discovering the virtual solder joint, repair the soldering with an electric soldering iron.

3) The quality of the crystal oscillator or IC is not good, and the working frequency is unstable or drifts due to the influence of temperature, at this time, it can only be replaced with an integrated circuit or crystal oscillator of the same model and frequency.

You get a mouse pad first to see if it will float, and if it will, there is a problem with the mouse. Hurry up and find a merchant for a change.

It's not the keyboard's fault, it's your mouse malfunction, and if you change the mouse pad, the fault may disappear

Mouse malfunction, previously had a similar issue.
