After the computer restarts, the self test shows an ahci porto device error

The most common is poisoning.

You first right-click on My Computer, Properties, Advanced, and in the Startup and Failback settings, uncheck the box before auto-restarting.

The most common**:

1 Viruses. When the "Shockwave" virus occurs, it will also indicate that the system will automatically activate after 60 seconds.

The Trojan takes control of everything on your computer from a remote control, including getting your computer back up.

Solution: Antivirus, remove viruses and Trojans in safe mode, or restore and reinstall the system.

2 System file corruption.

System files are corrupted, such as win2k, win98

The fonts in the fonts directory and other basic files of the system during the system run are corrupted, and the system will be forced to restart because it cannot complete the initialization when it is started.

Solution: Overwrite installation or reinstallation, or when booting up, press F8 to enter the system selection mode, and then select the last correct configuration, which I believe can solve the problem. The reason for this is that "Last Correct Configuration" will automatically restore your computer to a normal state where your PC's files have not been corrupted.

3 The power supply of the chassis is insufficient, the DC output is not pure, and the dynamic response is sluggish.

Users or installers often do not pay attention to the power supply and use the most cheap power supply, so it is one of the biggest suspicions that cause the automatic restart of the system.

CPU workloads are dynamic, and so are the current requirements, and they require dynamic responsiveness. Some poor quality power supplies have a long dynamic reaction time, which can also lead to frequent crashes or restarts.

4 The voltage is unstable.

The working voltage range of the switching power supply of the computer is generally 170V 240V, and when the mains voltage is lower than 170V, the computer will automatically restart or shut down.

5.Advanced power management in the trick.

Click "Start Settings Control Panel Performance & Maintenance Power Options", and in the pop-up window, enable or disable "Advanced Power Support" as needed. Try to disable Advanced Power Support if you're using it when the failure occurs, and try to enable it if you're using Advanced Power Support to disable it when the failure occurs.

It may be that there is a problem with the achi driver of the motherboard. Press the F2 or DEL button depending on the motherboard during the self-test. Go to BIOS, turn off ACHI, and change it to IDE to try.

Hard drives are going to die! Hurry up and get out the important documents! It is also possible that the hard disk cable or interface is defective, and it is very unlikely!

If you can enter the system after booting, you can quickly low-level the hard disk, and after the new partition, you can use it for a while!

Put it down, or there is a problem with the hard drive

Hehe, this situation has just happened in my family, and I went to repair it, and people said who made you lightly handed, and deleted things randomly! So he helped me reinstall the system! That's it.

I guess I got a Trojan virus, just kill it.

1) Press F8 immediately after booting or not turning on the phone to press F8 without moving to the advanced option to let go of the hand, use the up and down keys to scroll to select safe mode enter, enter the safe mode and use the software to kill the Trojan, uninstall everything installed before the accident, including the game, restore the system or reinstall the system (if you can enter the safe mode, it means that you have installed something inappropriate, uninstall all the inappropriate things before the accident, if not, restore the system or reinstall the remainder, if you can enter the normal mode, In normal mode, it is also done as above).

2) If the above methods can't solve the problem, first soft and then hard, reinstall the operating system, don't install software, patches, drivers, etc., and see if there are still problems 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.

Please note: If you restore the system or reinstall it, when installing drivers, patches, software and other things, be sure not to install the things that affect your accident this time, otherwise it will be restored or reinstalled in vain.

3) If it is caused by hardware problems, it is recommended that the grandson overhaul it.

4) If you have any questions, please ask me.

It is recommended to reinstall the system with a 360 first aid disc or system CD.
