The computer uses the SATA hard drive, in the motherboard BIOS may detect the hard disk the correct information, but enters the Windows XP system to appear the blue screen picture prompt "stop:0x0000007b", what this question is caused?
This is caused by the user opening AHCI mode, the default setting for the SATA mode option in many motherboard bios on the market is IDE mode, and the XP system does not have the AHCI driver, after installing the Windows XP operating system in this mode, if the SATA is directly in the BIOS Mode is changed from the IDE to AHCI mode, and when XP starts, the blue screen will appear because the SATA AHCI controller driver is not preloaded.
If the user does not need AHCI mode, simply change the SATA modes to IDE mode, how to: Reboot the computer, press F2 into the BIOS, and set SATA mode to IDE mode. Setup completes to enter the system normally.
If you want to turn on AHCI, you can install AHCI driver when you enter the Windows XP operating system by entering the Windows XP operating system, downloading the latest AHCI driver and installing it on the motherboard chipset, and then restarting the computer after you install the driver. Re-enter the motherboard BIOS settings, set the hard drive working mode to "AHCI" mode, reboot the computer, and solve the problem.
