建议重灌
因为安装时通常会灌入主机板的驱动程式
假如你换主机板 可是不重灌 可能会造成新旧主机板驱动程式的冲突

我试过一次，我把旧电脑的硬碟直接拿到新电脑去插，windows给你一个警告的讯息，然后我就重灌driver就没再出现警告，不过最后我还是重灌了..

不建议楼主构思!!
我曾有一次这样使用,造成无法挽回的情况发生!!
反正sxp快速安装,助益不少!!
多发点时间,资料做确保是上上策!!

1.升级CPU不需除重新安装XP
2.更换主机板强烈建议重新安装XP（省得自找麻烦）

我在网路上搜寻到了一个方法
已经用这方法更换了主机板(晶片组 KT333 -> KT600)
重新启动 XP 后会自动抓驱动程式
目前只有出现一个问题， IDE 装置的驱动程式安装都显示出现错误
但是使用上却很正常
用 EVEREST 看的结果，还是以 UDMA 100 在跑

方法说明如下，提供给各位参考

Install a new motherboard in a Windows 2000/ XP system.

If you upgrade your motherboard on your Windows 2000 system or tried to move
the hard drive to another computer, you may have received the following
error message 'STOP: 0x0000007B INACCESSIBLE_BOOT_DEVICE '. This is because
the hard drive does not contain the drivers for the hard drive controller
for the new motherboard.

If you are using a SCSI drive subsystem, usually you can install the target
disk controller in the old system and install the drivers for the
controller. You can then move the controller and the hard drive to the new
system, boot, and remove the unused drivers.

For IDE systems, it is a little more complicated since the IDE hardware is
usually integrated on the motherboard itself. When Windows installs, it
detects the IDE controller and only installs the driver for the detected
hardware. When you upgrade the motherboard or move the hard drive to a new
computer, Windows will not find the correct drivers installed. This article
will show you how to install the correct drivers so that you can move the
hard drive.

If you are interested to find out which drive controller Windows detected,
look in the file \WINNT\setupapi.log. Before you begin this procedure,
please have a good backup of the current system!

1. Boot the system using the hard drive in the old system. Copy the
following text into a file and call it copy.reg.

Im my experience, you need to copy the whole thing even if you think you
know the target driver.

2. Extract the following files from \winnt\system32\i386\driver
cache\i386\driver.cab and put them into the \winnt\system32\drivers
directory: atapi.sys, intelide.sys, pciide.sys, and pciidex.sys. If the
directory contains other cab files for service pack 1 (SP1.CAB) or service
pack 2 (SP2.CAB), get the files from there instead so that you are using the
latest files.

3. Right click the copy.reg file and select Merge to add it to your
registry. Confirm all prompts.

4. Move the hard drive into the new system and reboot. You should be able to
boot normally.

这个在Microsoft KB就有了...
KB314082

先去-系统-装置管理员-将所有的主机板驱动程式遗除之后关机组好主机板在重惯新的驱动程式因该比较不会出问题我试过一次^^
