The AHCI driver of the acer 4170G laptop cannot be installed when the XP system is reinstalled

First of all, you have to modify the registry, and if you don't change the BIOS, it will be a blue screen!

The basic steps are as follows:

Quit all Windows-based programs.

If the User Account Control dialog box appears, click Continue.

Locate and click on the registry subkey below:

In the right pane, right-click Start in the Name column, and then click Modify.

In the Numeric Data box, type 0, and then click OK.

On the File menu, click Exit to close the registry.

Then reboot, go into the BIOS, change the IDE to AHCI, and then enter the system, install the driver.

Go to the official website to see if there is the latest version of the BIOS, and updating the BIOS may solve the problem.

Acer's book, you'd better not change ahci to ide.,Definitely blue screen.。 Mine is macro basic, I've tossed it before, and I think it's useless. You now need to boot the computer and press F2 to enter the BIOS, there is an option for SATA Model, change it to AHCI and it should be able to boot.

If it's a solid-state disk, the effect of opening ahci is very obvious, if it's a mechanical disk, there's no need to toss that thing, it's not too effective.

Hello friends!

Blue Screen**: 0x0000007b

Error analysis: This ** has something to do with the hard disk, but don't be afraid, it's not a bad sector, it's a hard disk boot partition error caused by a setting problem or a virus.

Solution: If you have this problem when installing the system with the original system disk, it means that your machine configuration is still relatively new, as an old system disk, you don't recognize such a new hard disk interface, so you have to enter the BIOS to change the hard disk mode to IDE compatibility mode. Of course, people now use the ghost version of the operating system, and the newer ghost disk does not have this problem. As for the problem that people can't find the IDE item, because many motherboards indicate that the wording of this item is not the same, some of them say AHCI and Compatibility, and this AHCI is equivalent to SATA mode, and Compatibility is equivalent to IDE mode.

If your operating system has been used for a while, and suddenly this problem occurs one day, then sorry, caused by the virus, press F8 on boot, select the last correct configuration, and if you can't restore the normal mode, then please redo the system.

When you're done, please give me the answer. Thank you.

Just change the general machine to an IDE! This machine is said on the Internet to install SP3 directly will have a blue screen, and it is used to install the SP2 version and then install the SP3 patch! It's no different from installing SP3 directly, it's a bit troublesome.,It's best to install it with the original!

What if there's something wrong with the hardware???

Computer blue screen reasons.

Software compatibility issues cause a blue screen on your computer.

If the driver is not compatible with the hardware and may lead to the blue screen phenomenon, it is recommended to install the driver in the hardware gift disc (to match the operating system used), and the driver does not need to pursue the latest!

There is no blue screen phenomenon after using the computer for a long time, and one day suddenly there is a blue screen, which is generally caused by memory problems caused by too much dust in the computer (solved according to the methods mentioned below) and software and system compatibility problems. Or use the Windows System Restore feature to directly restore the system to the previous restore point for detection!

Poor contact of memory modules or memory corruption causes a blue screen on your computer.

During the operation of the system, almost all the high-speed data access operations are carried out in the memory, if the memory module is not in contact or damaged, the access of system data will be problematic, which can easily lead to the system blue screen and crash! Generally, poor contact of memory modules is caused by excessive dust accumulation in the computer, or the memory is not plugged in tightly! If there are two internal memory roots, you can unplug one of them to detect, and if you still see a blue screen phenomenon when reinstalling an official Microsoft original operating system, it must be determined that it is caused by a hardware problem!

Solution: Clean the dust in the chassis, unplug the memory module, wipe the gold finger with an eraser, and then plug it in again.

A virus Trojan causes a blue screen on your computer.

Nowadays, there are more and more types of virus Trojans, and there are various ways of transmission, which cannot be prevented, some virus Trojans infect system files, causing system file errors, or causing system resources to be exhausted, and may also cause the occurrence of blue screen phenomenon, it is recommended to install antivirus capabilities to emphasize antivirus software, such as Kaspersky, NOD32, etc. for detection, but as we all know, the update speed of antivirus software is difficult to catch up with the speed of the virus, which requires us to practice the ability to manually check and kill viruses, and it is recommended to use process Explorer forcibly terminates malicious processes (Microsoft's officially recommended process monitoring tool).

An example of using Process Explorer to detect and kill viruses: the solution to the problem that the IE homepage cannot be modified by yourself after it has been maliciously modified.

Bad sectors on the hard drive cause the computer to screen up.

Like memory, the hard disk will also carry some data access operations, if there is a bad sector in the area where the access and reading system files are located, it will also cause the system to fail to operate normally, resulting in a system crash and a blue screen on the computer!

Solution: Reformat the system partition after backing up important data (there will be an option to format when reinstalling the original Windows system), if the format is successful, it will not affect the use, otherwise you can only discard the partition or replace the hard disk.
