How come my computer freezes and I have to press CTRL + ALT + DEL to fix it?

Q: My taskbar is getting stuck sometimes or desktop but never both at the same time. To unlock it I press ctrl+alt+del and all comes back to normal. I reboot the laptop (HP vista home premium) about 5 tomes and still the same problem. I think it has something to do with the USB mouse I’m not sure. How come I still have the same problem after I do a restore to factory settings?
