I have a Hard disk problem

I bought a new PC for my son a week ago. Everything was running very great until last night when my son opened it to do some research, the following error messages appeared on the screen telling:
“Windows detected a hard disk problem. Back up your files immediately to prevent information loss and then contact the computer manufacturer to determine if you need to repair or replace the disk. ”
I understood and realized that the problem is in the hard disk as described by the error code but I’m just wondering why it happened as early as this time considering that the PC was newly purchased. The hard disk model is: Seagate ST3200827AS ATA device.
Frankly, my idea in computer technology is very limited. And so, please explain to me why it happened and how can I correct this problem.
Thank you for your help.
