Windows Freezes For a Few Mins

I have WXP Pro. Some times, like 3 times per Week, When I start the PC, The System Seems to be Halt for e Few Minutes.
Hard Disk Light is Off
I disconnect for Internet
Ctrl-Alt-Del Comes up, Press Task Manager, But Does Not Display.
After a Few minutes, Some times 5 Mins, Any Thing I have Pressed or Executed Shows up and the System continues normally
It only Happend when staring the PC, may be from off or standby
Any Ideas?
