I recommend grabbing the latest drivers for everything you can find, particularly your sound card. After that, re-apply DX 8.0. The RW direct-sound recording problems are a DX8 thing, I am on wav recording now too.
I do see one big potential cause for all of this though, your OC'd CPU. De-clock that sucker back to stock and try it. Yes I know what you are going to say, "Everything else works fine at that speed." but do it anyway. AH puts more load on your machine than anything else you likely do with it. There have been several people who's strange AH problems were solved by turning their CPUs back down to stock speed. Even if it's not the problem, you need to set it back to stock speed until you are done troubleshooting to remove it as a potential issue. Turn your video card back down if you've overclocked that as well. When you have all the problems ironed out, THEN try turning the CPU back up a bit at a time. Some folks have found that they can still OC, but they can't turn it up as high as they thought and still run AH.
