Help with keyboard and mouse
My PC USB mouse is broken and got a PS/2 mouse, made some mistakes deleting logitech registry entries. Now the keyboard doesn't work too.

Now the situation is,

PS/2 keyboard, PS/2 mouse, all USB unplugged, all works well in Linux. But on Win2003 (same PC) keyboard no response, mouse works in the logon screen, but when I press a key, mouse stops working. Seems some conflicts there. But even I disconnect mouse, keyboard still not working.

Keyboard works in repair console and lilo, before win2k3 is loaded. Clearly this is driver problem. The thing is, since keyboard no response I cannot even login to fix problem. Can I login by mouse? Does any high-hand has any clue how to fix this? I don't want to reinstall. Thanks.

safe mode应该不涉及驱动的问题吧。然后再重新安装必要的驱动试试看？

可能你的系统仍然认为你在使用USB鼠标。一点建议，
借一个USB鼠标来接上（去掉PS/2鼠标），这时候应该一切正常。（如果不正常，那么还有其他问题。）

在控制面板里的硬件管理中，找到鼠标那个项目，删除掉USB鼠标，然后关机。换成PS/2鼠标后重新启动，这时系统应该能够自动发现PS/2鼠标并安装好驱动程序。

估计是硬件冲突.
你的PS/2 keyboard和 PS/2 mouse可能有冲突,先拔掉PS/2 mouse,再到到硬件管理里面去看一下

Still no luck
in trying to restore registry. Finally decide to

copy windows\repair\system windows\system32\config

and keyboard works again. Hopefully other hives are untouched and I can keep most program settings except services.
