Random Reboots with blue screen of death

Hello,
This is my first post, I have a Gateway DX4831-01E that I Purchased
last week and was having issues with rebooting randomly and showing the
"blue screen" error message upon reboot. I took it back to Best Buy and
they gave me another one, stating that they thought it was a hardware
issue. I had quite a few things installed on that computer already that
were transferred from my old computer.

I got the new computer and this one has begun rebooting randomly on me.
I only had it working for about 3 hours before it started doing it
again. I can't imagine that there is two hardware failure issues in a
row with this machine...

Here are the only things that I have installed on the second computer:


-Itunes/quicktime for win 7 64-bit. I also imported all of my 4,000
songs from my last computer (I am no computer expert but I have a
feeling that one of the song files might be causing this due to the
some of the songs being downloaded as torrents in the "old days")

-Linksys program from a CD that makes it so I can use a USB wireless
card to get wireless internet on the computer. It is a 2.4GHZ wireless
G usb card from Comcast if that helps...

-A program, downloaded from the internet (I lost the CD) for my old
Lexmark Z605 Printer to make it compatible with this computer.

That is is...

Here is when it has crashed:

Listening to Itunes - twice
Watching a movie trailer which I downloaded from Apples website -
twice
watching a tv show on HULU.com

If you have any suggestions please let me know. Thank you.
