Windows 7: Constant freezing with seemingly no reason

Have you tried updating your drivers yet, especially the sound and Display?

Run this for a while and note if you have any lag spikes. It can tell you if a driver is causing it:

DPC Latency Checker
"Some device drivers on this machine behave bad and will probably cause drop-outs in real-time audio and/or video streams. To isolate the misbehaving driver use Device Manager and disable/re-enable various devices, one at a time. Try network and W-LAN adapters, modems, internal sound devices, USB host controllers, etc."

I suppose it can't help narrow down which driver it is?

no it won't directly tell you which driver but you can use it to narrow it down. Basically you have to have the program running while you disable specific non-critical drivers real time in the device manager one by one until the lag spikes go away.

If you are getting that long-winded message, that is a good sign you have drivers causing lag. I'm willing to bet it's your wireless card. Disable wireless card and check the results.

Running a stress test right now, but will try that once it's finished.

Don't base it on the message though, you'll need to see if you get the lag spikes on the graph or not. Do you get any spikes? Just run the DLC in the background and try to use PC normally. Try to stress it, run some programs with video/sound. A game would be perfect to see if you can get it to spike.

Not much of a difference. 80-40 is with network adapter on, 40-0 is off. I had my media player open and playing while running it (using 47,000k).

Well, had an interesting development in the last few minutes. Computer froze while running DPC, where the freeze occured is pretty obvious in the picture below. But, I also checked event viewer, and the picture below cannot be a coincidence, can it? It froze around the time of the events pictured.

Adobe flash? Well uninstall it and see, but I can't see that affect the latency. Your graphs are clear evidence something is very wrong.

At this point I would personally reinstall sound, video, LAN, WiFI, and chipset drivers.
