My mouse works then stops

Hello,
I just bought my dad a brand new Toshiba laptop. It worked perfectly for a week or so, including last night. Now all of a sudden about 45 seconds after it boots up the mouse freezes and stays frozen. I reboot and it does the same thing, works fine and then all of a sudden frozen. Its not hooked up to anything special, this is just the mouse pad on the computer...the brand new computer. I don't want to have to take this back to the store, I purchased it online. Please Help
