Audio/Video stutter during games, videos. Suspect ethernet driver
I first built this desktop last May and immediately played Crysis on it to test the graphics and whatnot. I occasionally noticed some audio stuttering and the game would freeze up for a split second, then it would be fine. I knew the hardware could handle it (my system spec but with an AMD Phenom II X4 965 Black Edition and an M4A89GTD PRO/USB3 motherboard), so it must be a software problem.
It turns out that Windows Update installed some bogus driver for my onboard Realtek Ethernet controller. So, I rolled the driver back, installed the version on the motherboard CD, and that was that. No more stutter.
Well, now I have a new processor, motherboard, and Windows installation and I've found myself in the same boat, except I can't fix the problem the same way. This is especially annoying since I don't even use my ethernet at all (not by choice, just no wiring). I have an ASUS PCI wireless card (which I was using on my previous computer when I fixed the problem) and I have updated the driver for that too (after trying the one on the disk). I have also updated the HD audio driver and the ethernet driver after reinstalling from the motherboard disk didn't help. I got the drivers from Biostar's website, not through windows update.
I've read that there may be interrupt line conflicts between the graphics card and the ethernet controller (IRQ conflicts), but if those are shared, they are supposed to be (at least as far as my experience with embedded systems programming has taught me). Either way, I can't change them in the bios, so it doesn't matter.
Does anyone have any clue what could be causing this problem?
