Only thing I've read on other forums is dropping sound quality in windows to 44 from 48 helps. I tried that, didn't help.
They fixed that bug in 1.2, IIRC. As for your crashes, do a fresh install with just the HQ texture pack loaded, then play. See if it crashes. If it does, it's likely that you're running out of VRAM, and I'd suggest not using the HQ texture pack. If it runs fine with a clean install, it's a mod that's messing you up.
So start adding mods back and play, and see which ones messes you up. Note that 1.4 changed quite a few things with regards to perks, skills and other behind the scenes stuff, so most of the mods that directly affected those are now broken.
