Windows XP Freezes oon Startup

[Joe]

Hello,

This is my problem:

When I startup my comp, a screen shows up giving me a
selection of:

1) Safe Mode
2) Safe Mode with Networking
3) Safe Mode with Command Prompt
4) Last Known Good Configuration
5) Start Windows Normally

When I click one of these Windows is supposed to open,
but before another screen appears, it freezes!!

I've tried choosing each one and the result is identical,
FREEZING!!

Can anyone help me fix this prblem and tell me what the
cause of this problem is?

Thanks in advance!!

Joe
