Why does it take about 1 and a half hours for my computer to turn on after it is turned off?

Based on your question, there are three possible reasons for this:

1. The load capacity and output current stability of the power supply are not good: it will cause the system to work unstable, and cause irregular restart, because some files of the XP operating system are damaged during abnormal restart, so it will shut down.

2. Hard disk has bad sectors: If the hard disk has bad sectors, it will often crash or restart when the system is working, and bad sectors on the hard disk will also cause system file damage.

3. Motherboard is faulty: If there is a fault in the motherboard, such as a failure of the IDE control part, which causes file damage or loss while working, Windows XP will also prompt you to back up the system.

Through the above several reasons, I recommend that you use the troubleshooting method to troubleshoot, first replace a stable performance, strong load capacity power supply to see the status, if not, you may need to replace the hard disk and motherboard. If you have enough time, you may wish to reformat the hard drive partition and reinstall a healthy Windows XP operating system to avoid the above failures caused by system software problems. You can open the case, wipe the dust off the CPU fan, and then determine if it's the CPU cooling problem!

Generally, reboots are caused by poor CPU heat dissipation! If you don't open the case cover, you can't solve the problem by subjective assumptions!

When you can turn it on, Master Lu Test the hardware temperature It should be too high, or when you turn it on, you can hear whether there is any abnormal noise, and if there is an abnormal sound, it should be that the hard disk is broken.

Whether the machine is new or old. If it is an old machine, please take the machine to a special cleaning shop first.

Clean the inside of your computer from dust. If it's a new machine. It could be a hardware issue. You'd better get it to the computer company you bought and ask him to do the hardware test.

There are several reasons why a computer will automatically shut down:

1.Generally, the automatic shutdown may be caused by the high temperature caused by too much dust in the CPU fan, if so, clean up the dust of the CPU fan and heat sink, and add new heat dissipation silicone grease.

2.It may be caused by problems with motherboard components or power supplies, voltage instability, hard disk failure, etc.

3.In addition, a Trojan horse can also cause a shutdown due to a system failure, but the probability of this is very small, restore the system or try to reinstall it.

4.If it automatically shuts down or standby without operation, it may be a problem with the settings. Right-click on the desktop to select Properties Screen Saver Power Supply Select a suitable plan from the drop-down list in the power usage scenario, and set "Never" in the list of Monitor Off, Hard Disk Off, System Standby, and so on (or set an appropriate time) below.

Is there a problem with the fan, take a look at the memory.

There is a problem with the fan heating, and the CPU temperature is too high.

It's not going to be in standby

Did you use any software that was scheduled to shut down?

1. If the motherboard BIOS cannot support ACPI well due to computer hardware reasons, it is recommended to upgrade the BIOS of the motherboard, which can generally be solved;

2. Check [Advanced Power Management (APM]]: open [Start]|Settings|[Control Panel]|[System], and then click [Device Manager]. [System Equipment]|Advanced Power Management, click Settings, and remove the check mark before Enforce APM.

If the computer shuts down normally after restarting, the cause of the problem may be APM, and the advanced power management function should be turned off;

3. Disable rapid shutdown: Click [Start]|[Run] menu, enter "msconfig" in the command box and click [OK], then the [System Configuration Utility] window will appear. Click the [General] page, and then click the [Advanced] option, and in the [Advanced Troubleshooting Settings] window that appears at this time, select the box in front of [Disable Quick Shutdown].

If the computer shuts down normally, there is a problem with the rapid shutdown;

4. Check whether all the applications have been closed when the phone is shut down. If not, you can close all applications. Because some applications may not close properly, and the system may not be able to end the application normally, resulting in malfunctions;

5. When using a browser or higher version to surf the Internet, it should be noted that they still occupy a lot of system resources after exiting, usually making the available resources of the system less than 80%, and it is easy to make errors when running other software after that, which is likely to cause the system to fail to shut down softly.

1.Click on "Start Control Panel Performance and Maintenance Power Options". In the pop-up Power Options Properties window, click Advanced Power Management and tick Enable Advanced Power Management Support.

2.This is most likely XP Ghost or the default system that is doing Ghost without automatically updating the system that adapts to your computer hardware, and you need to uninstall and reinstall the advanced power management program and adapt it again.

In this xp system that can't be automatically shut down, right-click from my computer to enter management, in the device manager, uninstall the ACPI related to the system device, ACPI Fanacpi Fixed Feature Button

acpi thermal zone

micosoft acpi-compliant system

All four are uninstalled.

Then rescan the new hardware. Let the system recognize the hypervisor for reinstalling the advanced power supply on its own.

Addendum: I've done a lot of this step.,It should be able to be solved.,It's really not good.,You just search for a [XP shutdown patch] on the Internet.。

3.Open the registry.

Change the numeric data to 1

It should be fine.

Isn't it very slow when you boot up?,If it is,There's too much of a file in you.,Need to delete some.,If it doesn't work.,Maybe it's a virus.,Antivirus,It doesn't work anymore.,Reinstall the system!

Memory problems, see what processes in your process occupy more memory, end it first and then restart.
