Dell laptop year old hitting Payguard ?

My mom did an online servey and got a free dell laptop for comepleting the servey.That was a year and half ago.

Now its doing something very strange its letting her do what ever she wants for ten minutes the locking up and putting Pay guard on her screen.The company she got it from is going through chapter 1 bank rupture.And the numbers for saport are no good now.

Any ideas of whats going on?And how do we fix it?
