[QUOTE="doveman, post: 828973, member: 67412"] I was having trouble with audio/video glitches and seemed to have tracked down the cause of the high DPC spikes to Outpost Security Suite Free, which was definitely causing them and killing it stopped them. They've started recurring again though, not as bad or often as before and I haven't observed any glitches but I still need to sort out what's causing them. I've tried disabling the Realtek PCIe GBE NIC, the AMD High Definition Audio Device (on my 6950), the Realtek motherboard audio, the two Reneas Electronics USB 3.0 Host Controller devices and the VIA 1394 OHCI Compliant Host Controller but still I'm getting occasional spikes of 1000-2000us. Actually, I've just re-enabled the Realtek NIC and didn't see anything above 435us for a few minutes, but just got a spike of 1523us. I don't really know what the stats mean in LatencyMon, so I've uploaded a screenshot if someone who does could be good enough to take a look for me.
