The computer takes more than half an hour to boot up, and it is abnormal after starting. 100 points

Halo The basic poisoning pretend to have been experienced by you I've used the computer for so many years to see viruses that have been so serious @

Rising doesn't do anything

Install a nod32 I prefer this, it's free, and it consumes less memory. The effect is also good.

If it still doesn't work

Use win pe (if you can't, go to the Internet to see the specific operation) to copy out important files, DOS under the full format!

Redo the system and install a good antivirus. Before copying the copied files back to the computer, be sure to disinfect the USB flash drive containing the files.

If the machine is relatively long, remove the CPU and clean it up.

Ok a genuine XP Home is scrapped.

Give it to me, I can't even ask the question.

It should be a very powerful Trojan virus. I can't help it.

It's a virus, if you want to copy out important files, you can use win pe to enter the system, and using pe is equivalent to turning your machine's hard disk into a slave disk, so it should be no problem, you can copy out the important files on the c disk. Or you can try to kill the Trojan, recommended tools, windows cleanup assistant, 360 trojan kill, ice blade, must be the green version, upgrade the database to the latest on other computers, and it is best to change the name when running. After this check, a large part of the virus will be removed.

It's a virus, really, I've had it before, and there's no way to reinstall the system!

Does the computer stay on for a long time? Is the computer often optimized with system optimization software? If so, there should be 3 possibilities:

First, the computer does not shut down for a long time, resulting in the internal temperature of the computer is too high, and the CPU hard disk, memory and other hardware cannot work normally, resulting in slow system response. If you shut down the computer directly, it is easy for the computer system to lose files, resulting in system instability and other conditions.

Second, this problem will also occur if the computer does not dissipate heat due to poor heat dissipation, the cooling fan does not rotate, or the speed is slow, resulting in the computer not being able to dissipate heat.

Thirdly, the computer often shuts down abnormally, or the computer often runs in a vibrating environment, resulting in the loss of computer system files, and the computer hard disk is unstable due to large vibrations, which may cause this phenomenon.

Suggested treatment: try to shut down the computer when not in use, pay attention to the heat dissipation of the computer, shut down in a normal way, do not directly press the switch by hand, it will be very harmful to the computer for a long time, the correct way to shut down is to click the start menu at the bottom left of the computer, and click the shutdown button. Install the system from the ground up.

If so, then focus on the hard drive, followed by the CPU or memory module!

For system problems, it is recommended to reinstall the system.

I've had this problem too. But after a while, you'll want to make sure the cables are in good contact.

It is indeed a typical heat dissipation problem.

You'll need to clean the inside of the case and remove the heatsink and fan from the CPU to clean it.

Also, new silicone grease needs to be applied between the CPU and the heatsink to conduct heat.

Note: To clean the heatsink as well as the old silicone grease left on the CPU, and then apply new silicone grease, do not apply too much, a thin layer is sufficient, too much is not conducive to heat dissipation. The main purpose is to fill the gap between the heatsink and the CPU with silicone grease.

If it is too thick, the heat dissipation of silicone grease is not as easy to conduct heat as metal, so it is not conducive to heat dissipation.

Silicone grease is very cheap, and the general retail price is 1 yuan.

Upstairs was right! It's really a problem with the CPU fan! Because when you use the machine, the CPU fan is not enough for you to overclock the temperature, causing the shutdown you said!

Today's machines are like this, when the CPU reaches a certain high temperature, it will appear, automatically shut down, and automatically restart!

Change the fan: Internet CPU fan, 30 a, the general may be 20!

Your computer has a protection system, the CPU temperature will automatically shut down when it reaches a certain temperature, and it can only be turned on when the CPU cools down. I'm going to go to the pit to fix it!

CPU Cooling Problems The fan is broken.

There may be one of the following reasons why your computer automatically restarts

1. Computer heating may lead to restart, it is recommended to install Master Lu to monitor temperature changes, if the temperature becomes high and restart, then it is a heat dissipation problem, it is recommended to disassemble the machine to remove dust, and replace the processor heat dissipation grease, etc.

2. If there is no problem with heat dissipation, then it may be a system problem, such as software conflict or virus factors, it is recommended to restore the factory system or reinstall it.

3. If the system cannot be solved after restoring the system or reinstalling, then it may be a hardware failure.

This is a self-test of the booted hard drive. The reason for this is that either the shutdown is illegal or the hard drive is about to be reimbursed.

If the hard drive has been used for several years, and you can often hear the sound of "card card" during operation, please make a backup of important data as soon as possible.

You can only wait once. After that, it will be able to boot up normally. Because you had a power outage before. Or it doesn't shut down properly.

Go reinstall the system.,I guess you're forced to shut down.,Just press the button.。

Reboot failures don't happen for no reason, right, what did you do before restarting? What hardware has been upgraded? You can elaborate on that.

1. It may be that there is an incompatibility between the system or programs, press F8 to move to the advanced option when you boot up, and select "The latest correct configuration" to enter the repair, and it is not possible to press F8 to enter the safe mode to restore the system or reinstall the system.

2. The CPU or other hardware temperature is too high, and the memory and graphics card are incompatible or faulty.

3. If the hard disk has bad sectors, please use the system's built-in functions or software to repair the disk, or format the hard disk to repartition and reinstall the system.

4. Power failure and voltage instability can also cause automatic restart.

5. Incompatible drivers can also lead to restart.

6. Failure of motherboard parts.

7. Change the default automatic restart of the system: right-click on My Computer Properties Advanced Settings in Startup and Failure Recovery Remove the check mark before "Auto Restart" in System Failure, and then press OK and Apply to restart the computer.

8. If the above methods are ineffective and you can't find the problem, it is recommended to overhaul it.

Go to the Device Manager and check if there are any conflicting places with the various drivers, and if there are any yellow ones! If there is a possibility that the device driver is incompatible with the system; Then delete the drivers of the sound card, graphics card, network card and other devices, and then install the drivers one by one, Xiangshen restarts the computer every time a device is installed, to check which device's driver is caused by the failure of the program, after finding out, the new version of the driver of the faulty device, and then install it. Then clean the dust in the computer, clean the memory, graphics card and other devices, and reinstall the memory and other devices.
