Longhorn 4051 Normal Boot Login Error?

[xptablet]

Hello all,

I have recently installed Windows Longhorn 4051 PDC on a second partition of my harddrive. All worked fine..... until turning of the pc last night, coming back to it today only to find that when I boot LH in normal boot mode, it prompts me for CTR-ALT-DEL (as usual), but when I press those three buttons, it does not work... so I disabled that feature in safe mode, and now i still get stuck at the same place, but it stands still on "Loading GPClient"

Any suggestions would be greatly appreciated!
