A user running Windows 7 has reported that a computer has crashed and a BSOD displayed. The
computer was restarted and now the user reports that it is running slower than usual, especially when
multiple programs are open at the same time. The technician knows the system has 8GB of memory (2x
4G DIMMS), and suspects that the system has a faulty memory module and has disabled one of the
DIMMs. Which of the following would a technician do to confirm that the OS is now only detecting 4GB of
memory?
