That's why it's wise to get yourself some programs to check out what's inside the case and test your rig against other machines or compare them with results shown in hardware reviews. But do you know exactly what you've got? Has your machine got the parts it's supposed to have? How well is that PC actually working? These are really important questions! You might be into overclocking and tweaking your system to make it run as fast as it can. Maybe you've upgraded your computer with a new CPU and motherboard. You've just bought a new gaming desktop, or a laptop for the office.
