Also, as for the bsod. Download a temp monitoring program like Coretemp or Realtemp and see if it is your processor over heating. The heatsink could have just come loose during shipping. If it is not the processor over heating then download Memtest86 and burn to a CD-R and run it. Those should be the two most likely culprits if the bsod is only happening a couple times a day.
