Why does my computer turn off and start up? It s a 98

See if the CPU fan is broken.

It's not a problem with a bad fan. I've come across it before, but then before I knew it, it got better.

This phenomenon occurs because multiple users are open on the computer. This prompt appears when the login screen is closed, you need to switch the user mode so that the original mode is still running.

The so-called shutdown of remote computers is not remote in the geographical sense, and the system is now multi-user. Once you have logged in with your account, you will be logged in with your account again. If you choose to close your account, it will prompt you to be remote.

Win7 is an operating system developed by Microsoft, with a core version number of Windows.

The win7 system can be used in home and business working environments, laptops, tablets, multi-centers, etc., with the characteristics of fast start-up, simple operation, safe and easy to use, and high efficiency.

B is Microsoft's codename for future versions of Windows, which was originally scheduled to be launched after Windows XP. However, in August 2001, it was abruptly announced that the launch of "Blackcomb" would be delayed by several years, and that it would be replaced by Windows Vista (codenamed "Longhorn") after Windows XP and before Blackcomb.

Windows 7 has many user-friendly designs, such as fast maximization, window half-screen display, jump list, quick system fault repair, etc.

Windows 7 has greatly reduced the boot time of Windows, and it has been measured that the system load time is generally no more than 20 seconds when running in a low-end configuration in 2008, which is a big improvement compared to the more than 40 seconds of Windows Vista.

1.If you're a LAN user, it's possible that you have a shared file on your computer, and someone else is sharing your file for use or viewing.

2.It is also possible that your computer has been poisoned, a Trojan horse in a shell, and someone else is already remotely controlling or viewing your computer.

3.Let's kill and kill the virus, under the 360 system first aid kit, if it still doesn't work, then it's best to reinstall.

This means that someone is remotely logging in to your win7 system, win7 can be multi-user, don't you know? If you don't know who it is, it's best to reset the password of the account opened in the user and group, such as administrator, whether the guest account is open, and if so, close it. It should be ok after restarting.

If you want to see which account is logging into your computer, you can do so in Control Panel - Management Tools - Remote Terminal. You can also log out first, and then the login screen should show what accounts and login status.

Others are sharing your shared folder, this situation occurs once or twice, it's okay, you can use 360 to patch the security vulnerability, often if this is the case, you should still consider setting a login password.

You're remotely controlled, right? That's called remote login.,It's like when you log in to a** is actually logging in** computer server.,Oops,In short, it's very clear.。

Let's kill the poison and turn off the remote control.

Install a 360 scan, it's really not possible to install the system. There are too many problems with win7, it is recommended not to install it for the time being, it is easy to break down the hard disk.

It can't be someone else connected to your computer.

Mine is also this version, without the appearance I said.

Windows remote login will do it. Dropping it off may not work. But everything else will do. The premise is that the network can be connected.

It's not realistic, unless you're a hacker who writes the Trojan yourself, and then you have a Trojan on your home computer, but it's really not realistic, and there's a way to do it, you just set a BIOS password, and you can't even see the desktop except you, and you can't turn it on.

No software, just XP system comes with you can start --- programs--- accessories--- communication --- remote desktop connection Enter the IP of your home computer After connecting to it, enter the username and password to control, provided that the computer is on.

==It's okay to just turn off that computer.

Install a Trojan horse on the school computer and set a password;

Install a client on your computer at home, and you can control it, and you are not afraid of others controlling your computer.

I know that remote assistance can be done on QQ, but I don't know anything else, I guess what you said is not realistic.

In this case, it is very likely that you have opened two users, click "Start Menu" - "Switch Users" to see the second user. If there is no second user, it may be that the program created a user, but of course it is generally not possible because the software is not so powerful.

The virus has been hacked, and the phone is turned off decisively, and the antivirus is going to find a master to help.

I guess it's a virus that tampered with the file.

It's locked when you turn it off, it's okay, mine too, I hope it works for you.

It is recommended to redo the system and run it to see, if there is still this problem, then it may be a motherboard or power supply problem

It is estimated that there is a virus, you redo the system to try, if it still doesn't work, there is a problem with the motherboard, and a professional needs to repair it.

It is clear that the possibility of CPU heat dissipation is greater than other possibilities, save money: you can clean it yourself, and if you clean up the dust on it, it will cost you about 80 to change it for good luck.

It could be a hacker, but it's unlikely, or it could be a new type of Trojan.

Therefore, the best policy is to "redo the system".

System restore, try.

Unplug the network cable and take a look, if it really doesn't work, just reinstall the system.

There is a virus in your computer, just reinstall the system!!

Find your Ethernet card in My Computer > Right-click > Device Management, right-click Properties, Advanced, find something like Wake on LAN (different options are different for different laptops), and disable it.

It's a problem with the power management system. It is the ACPI on the motherboard, and it is recommended that you send it to the seller for repair.

You have opened multiple users, and this situation will occur after switching users and then shutting down, the solution is to log in to another user first, save and close the running program and then shut it down.

1. Enter CMOS, in the power management menu, PME Event Wake Up should be Disable, 2. Click My Computer, Properties, Advanced, Settings, and turn off the automatic restart function if the system fails. 3. The software is incompatible, which often causes the problem of shutdown and restart, which is the new machine of XP. Workaround:

Right-click on "My Computer" and select Properties. Select the "Advanced" tab, find "Startup & Failback", and click the "Settings" button next to it. Remove the checkmark before "Auto Restart" in "System Failure" (if you're only using XP, you can uncheck all the checkboxes you see, which will speed up the boot of Crack XP).

4. Enter the safe mode, if it does not restart after shutting down, continue to check the system reason, if it restarts after shutting down, replace the power supply.
