You need to find out how much RAM is installed in a system What command do you enter in the run dialog box to launch the system information utulity?

Well there's quite a few ways of doing this.I would recommend you open up start menu then right click on my computer and it should come up with all the system information including how much RAM is installed on your PC.

Another way of doing this is going to start menu clicking on run then type in the box dxdiag then press ok. Here you will also find all the details including how much RAM(memory) you have.

Good luck as per Page 231 of the A+ guide to hardware text, the applying concepts box at the bottom, to use system information, in the Run dialog box type Msinfo32 and press enter MSINFO32.
