Apr 29, 2013 8:39 AMby mende1,HelpfulYou are referring to Apple Hardware Test. In new Macs, it has to be downloaded from Apple, so you can do it holding Option (Alt) and D keys while the Mac is starting.
However, you have an old Mac. Old Macs came with Apple Hardware Test in the hard drive, but if you erased the hard disk or you upgraded Mac OS X, it was gone. Now, in order to use Apple Hardware Test, you need the Mac OS X DVDs which came with your Mac, so if you haven't got them, call Apple to get replacement DVDs > http://support.apple.com/kb/HE57
When you receive them, insert the Mac OS X DVD and hold the D key while your computer is starting. To make sure that Apple Hardware Test checks your computer correctly, make an extended test.
As you have problems with Internet, it won't probably detect anything. Are you using Internet from Wi-Fi or Ethernet? Have you tried to connect your computer in the other way (if you are using Wi-Fi, use Ethernet, and if you are using Ethernet, use Wi-Fi)? Does the problem appear on other computers?
