XP windows freeze at start up

[leavipat]

I have had my computer for about three years and it freezes at the windows XP logo screen. This happened last month and I had to pay to fix it and now it just happened again. I'm on my granddaughters computer now.
It get this Reg Cure ad. Do you think this will help. I need to lean how to solve this problem myself.
Thank you for help.

To get help from individuals in a case like this, you need to describe if you have installed any new programs/downloads lately and what antivirus and firewall you have and whether you use a router or direct-to-modem connection.
