I just installed a stick of RAM 4 GB, total should be 8 GB with the other 4 that was already in there. So I installed the new 4 I got and when I click on properties under computer, it still says 4 gb, whereas I go to system properties where it tells me what OS I'm running etc. It says Installed RAM is 8 GB. So I'm confused. My computer is running faster so I'm guessing it's in there? Thanks in advance
