The absolute easiest way to tell if you have integrated sound or a sound card is too look at the back of your case and see where your speakers hook up. Is it down by the PCI slots, or is it up withing the IO shield with your mouse, Keyboard, serial and Parrallel ports. If it is in th ioshield, it's integrated. If it is in the card slots, it could be either. Pop open your case and see if there is a sound card or just a small plate that doesn't actually go into the PCI socket but just uses a cable and the slot. Confusing? Just check where your speakers are plugged in and see if on the inside of your case it is actually a card plugged into the PCI slot. Most integrated sound solutions take up alot of CPU power and you don't really have much to spare when it comes to gaming.
By the way, I disagree with the reinstall Windows suggestions. That may be your solution but it isn't your starting place. Run those benchmarks and lets see how your system scores. Why reinstall windows only to find out your cpu/mobo/ram are holding you back. most problems can be solved without reinstalling windows. If you have a 3 year old installation of Windows 98, a reinstall would be a great place to start. But Win XP is better than most people think. That doesn't mean you never have to reinstall it, but just don't use that as a First course of action.
I just hate hearing people say right away... reinstall windows. Especially without knowing what level of experience and knowledge people had. I can tell you that at least 1/3 maybe 1/2 of my customers have NO BUSINESS even thinking of reinstalling windows themselves. If they did, they might never see their computer booting properly again. And I can just imagine the lack of data backups most people do. It's not that it is really that hard, but for someone who never has done it, it could be dissasterous.
By the way, I am not at all implying that you couldn't reinstall windows. I am just stating it isn't good advice to tell everyone and anyone to reinstall windows, without helping them diagnose their problems first and finding out if they are up to such a task.
Such advice may be a way of getting noob's off the forums as they might never be able to get online again. At least those folks wouldn't be able to come back crying and screaming at the ones who just blurt out reinstall windows.
