注册文件导致笔记本蓝屏？？？？

我用的是正版本XP, IBM笔记本。把注册文件Copy到安装目录后，重新运行软件，不能正常进入取名页面。
后重起计算机，才可以正式进入软件。在使用一天后，关机，在此期间未安装任何新软件，未添加硬件。

但第2天重新开机时，却发现进入不了XP。本本直接蓝屏，出现提示如下：
A problem has been detected and windows has been shut down to prevent damage your computer.

If this is the first time you’ve seen this Stop error screen, restart your computer. If this screen appears again, follow tese steps:

Check for viruses on your computer. Remove any newly installed hard drivers or hard drive controllers. Check your hard drive to make sure it is properly configured and terminated. Run CHKDSK /F to check for hard drive corruption, and then restart your computer.

Technical information:
*** STOP: 0x0000007B (0xF7903524, 0xC0000034, 0x00000000, 0x00000000)

不论是进安全模式还是正常启动，甚至用CD重装XP，都出现此蓝屏。 现在都不知道怎么办了。
