I recently purchased: [URL]http://cgi.ebay.com.au/ws/eBayISAPI.dll?ViewItem&item=6879014810&rd=1&sspagename=STRK%3AMEWN%3AIT&rd=1[/URL] After installation, when I try to boot it up, I get the error where I have to choose to reboot in either safe mode, previous settings, or just start Windows normally. When I choose any of these three options, the computer just restarts (and it reaches the same stage again). Did I purchase the wrong type of RAM or did I do something else wrong? Thanks :)
