You don't have a logout program in your startup item

There is a problem with your USB flash drive.

First. It is recommended that you use the latest version of the mainstream antivirus software in safe mode.

There is today's latest Rising Star.

Break a leg. If there is no virus.

Try formatting the USB flash drive.

If there is a problem with the system, you can install the system again.

Hello landlord.

Is the system incompatible?,Or recall what you've done recently and don't rule out poisoning.,It's recommended that you re-check and kill.,You can enter the safe mode to check and kill.,It's recommended that you use antivirus software to detect the Trojan virus.,Clear it as soon as possible.。 Generally, when the Trojans are scanned, they will help you check all the Trojans, and you only need to click "Clear Now". Some Trojans require a reboot of the computer, so don't bother to get rid of the damage completely.

The rescue method of automatic logout after the computer is turned on.

Generally speaking, the cause of the failure is the loss or corruption of the file. The solution is to re-extract a new file from the WinXP installation disc with the Windows Faulty Console. Start the fault console, enter the windows system32 directory, and then enter REN to change the name) and press enter, enter map, put it into the WinXP installation disk, and enter expand x:

i386, then press the enter key, enter exit, when the computer restarts, take out the winxp disc, the computer can start normally. I came across a WinXP machine, infected with a worm virus spread by MSN, the system logs out directly every time you log in, the security mode is the same, and the correct configuration is useless in the end.

Start with the system disk, log in to the recovery console, and restart Copy C: Windows System32 to log in normally. The reason is that the msn funny virus destroys the normal and changes the userinit key from c:in the registry under hkey local machine software microsoft windows nt currentversion winlogon

Windows system32 , changed to C: Windows system32, so after copying, WinXP can find this login handler to successfully log in, log in to the system and restore the registry key again. In addition to repairing with the installation CD, it can also be repaired online via LAN (remote modification of the registry):

For example, run the hostname -u admin username -p password c: windowsegedit -s d: in pstools, and the content is as follows:

windows registry editor version [hkey_local_machine\software\microsoft\windows nt\currentversion\winlogon]

userinit"="c:\\windows\\system32\\"

This could be a system issue! The most straightforward way is to reinstall the system. If you back up your system before something happens to your computer, it's easier to restore it.

If it doesn't appear often, just press the power off button to turn it off. If it happens often, you can try it as follows:

1. Use the latest version of anti-virus software to conduct a comprehensive investigation and killing.

2. The software or driver is not compatible with the system, reinstall or upgrade the driver.

3. Faults such as memory, graphics card, hard disk bad sector, etc., in addition, voltage instability can also cause crash failures (if the memory is too small, upgrade the memory).

4. Incompatibility caused by upgrading hardware.

5. Too many junk files, too many disk fragments, etc.

6. If it still doesn't work, it is recommended that you go to the computer maintenance department for testing.

- -I haven't encountered this problem, if the C disk has no important data, then reinstall the system put...

I can't get into the system, it's troublesome.。。。

If there is an important one, use the system disk to enter the PE to back up the data of the C drive.

Let's redo the system, it's better to format all the disks.

What kind of antivirus software are you installing, it is estimated that the useful programs have been deleted, and you will switch to 360 antivirus software in the future, so that the problem can be avoided.

Throw the system disc in and reinstall it.

Don't look at what they say, if the hard drive has confidential files, find a reliable technician to fix it. Nothing secret, immediately reinstall the system.

The biggest possibility is that there is a problem, it is the core process of the system, if there is a problem with the process, it will cause the machine to fail to log in normally; Judging from the symptoms of the landlord's machine, it is recommended to format the reinstallation system!

Reinstall the system because one of your system files was deleted.

Boot press F8 --- last correct configuration.

If that doesn't work, restore the system, or reinstall it.

The problem of setting up the virus during antivirus, the cleanup is not successful, and the infected files are automatically deleted. It is recommended to format the hard drive and reinstall the system.

See if Safe Mode can start.

If it can be activated, use the 360 first aid kit to kill.

In addition, there is an option for 360 emergency start when it is activated, and it is activated with that one.

Lost files can be made using online tools.

If it doesn't work again, it is recommended to reinstall.

What a killing, it can't be that the system is infected. Then get rid of the system files!

There is a problem with the CPU fan and motherboard The south bridge on the motherboard will automatically shut down when it overheats, and the CPU temperature will soar. There are 3 steps.

1 Add a ball fan to the heatsink of the south bridge chip of the motherboard, which is usually 5 cm.

2 Remove the CPU fan and wipe the previous silicone clean, and reapply a new layer, be sure to be even.

3 The temperature is generally very high in summer, and if the CPU cooling fan is original, it is recommended to change it, the original fan has average heat dissipation performance It is easy to protect the heat in high temperature weather It is to automatically shut down, and it works very well to change a copper core fan.

The above 3 points can basically solve your problem.

This is normal, first of all, you haven't cleaned your computer after using it for too long. This is also the case after the CPU temperature is too high, and the unstable power supply is also one of the causes of this situation.

There is some truth to the answer below, but also check that the memory modules are loose and that the motherboards are connected to the individual lines correctly.

I think I should reinstall the system, and my computer is also constantly having problems now, and the antivirus is useless. But I'm not going to pretend you can try.

This condition is not necessarily the cause of the poison.

According to your description: after automatic shutdown If the computer can be turned on normally, then this situation may belong to the self-protection function of the system. Are there other objective reasons?

For example, the voltage is high and low and unstable, the interference of other electrical appliances in the same power line, the indoor temperature is high, the large program (game) is running for a long time when the computer is turned on, the case heat dissipation is not good, poisoning, the CPU usage rate is often 100, etc. You can install "Master Lu", in addition to the software can comprehensively clean and optimize the system, you can also detect all the hardware and software information of the system, you can detect at any time, and compare with the previous information, from which to find problems.

Frequent automatic power outages can cause harm to computer hardware, and the consequence is to shorten the life of the hardware.

Well, it's summer, you see if it's too hot, and if it's too hot, clean it up. Because now the weather is too hot and there is too much dust, which is not good for the machine.

Immediately after starting, press f8 to the advanced option to appear in the let go,Select "the correct configuration of the latest hail front" Enter to repair,It is not possible to press F8 to enter the safe mode to restore the system or reinstall the system (if the reinstallation is also reboot,It is recommended to overhaul it,If you can enter the safe mode,It means that you have installed something inappropriate,Uninstall all the inappropriate things before the accident,Or restore the system or reinstall)。

First soft and then hard, such problems are caused by software conflicts, inappropriate drivers, and system problems, you can restore the system in safe mode, or not reinstall the operating system, do not install software, patches, drivers, etc., and see if there is still a problem with booting? If you don't install drivers, patches, and software step by step, and find something that isn't suitable, don't install it.

If there is a hardware cause, take out the motherboard battery and put it on the charge, plug and unplug the memory, clean the graphics card, check whether there is a problem with the hard disk in La, and if it doesn't work, just overhaul it.

Use the system that comes with the system restore method:

The system comes with the system restore: "Start" "Programs" "Accessories" "System Tools" "System Restore", click "Restore my computer to an earlier time", press Next, you will see that the date page has a dark date, that is the restore point, after you select, click the next step to restore (win7 restore the system, right-click on the computer to select attributes, select system protection on the right, system restore, follow the steps to do it, you can also choose the source of this page to create at the bottom in advance, create the restore point yourself).

Some computers can fix it automatically, but yours can't.
