My Windows XP is completely frozen after installing Utilities 15.0

Dear Friends,

 

I installed Norton Utilities 15.0 on my ThinkPad T43 operating MS Windows XP. The installation was successful. But after running the initial Utilities clean-up function, my laptop will not reboot.

 

I've tried every Safe function, and repeatedly have tried to open Windows the normal way. The screen turns blank.

 

Does anyone know a solution? I would like to reboot the machine, then delete Utilities.

 

Thank you,

Peter
