a few weeks ago I had to reinstall Windows 7 completely because I broke my old setup by accident. After I reinstalled it and got the audio drivers to work (got them from the MSI website, my motherboard is MSI P7N SLI Platinum), for some reason, anytime something downloads, the audio stutters.
I have 4GB RAM (Although on idle it's more or less 50% used but I do have a lot of programs running, but I always have). Here's what happens: For instance, I'm playing a youtube video. Until it finishes buffering to the end, it will lag and be choppy. It's mostly evident in the audio but I can see it in the video as well. On other websites that carry slightly heavier and less compressed video, such as GameTrailers, watching videos is a nightmare in the beginning until it presumably loads (they don't have a buffer bar sadly but I'll just assume it downloads).
Later on I also noticed this that literally whenever something downloads, seemingly the rest of my computer slows down. While it's technically fine when I just use it, when I play a game and Steam (the digital game vendor by Valve if someone is unaware) starts downloading/updating something, whatever it is I'm playing starts to lag terribly. Note that the games I've noticed this in were also running from Steam, I hadn't really tested others. I'm kind of used to it now and just wait the lag out until Steam finishes updating.
It's really frustrating. Downloading files isn't supposed to do this to computers as far as I know. But for some reason it places such a load on my computer that everything else stutters. Maybe I can change the priority of downloads or something, I read something about IRQ here (no idea what that is really), but if there's some way I can fix this then please let me know. Thanks.
