Sound and Video issues

[Akiyama]

Okay, so this random hits me. Lemme rundown how the problem occurs and what gets borked.

So I was playing PSO last night (lol) on the PC with a friend of mine, and with Skype up when this happened. It's the second time in a few days that it's happened, and it's also happened when I had another game up while playing music at some point as well.

What happens is I'm doing shit, doo doo doo.. talking to them, and then boom. PSO crashes, Skype goes apeshit and goes 'Not responding mode' along with PSO, so they both crash down completely. I open firefox, but firefox doesn't work either. It just locks up on a the white screen before reloading pages. Google Chrome works decently, and so does IE, but they both have issues loading certain sites. Foobar2000 also acts fucking weird. Any time I hit play on a song, it'll make this really loud, scratchy noise as if it were a sound driver issue.

Oddly enough, the whole issue is solved by simply restarting.. but there is no way in hell that the problem is normal. My only guess is it's some sort of video/sound issue.

My specs are I'm on Windows 7 64-bit, GTX 460 on 258.96 drivers (they seem to perform best for me in comparison to other versions) and drivers on my sound card and what not are all up to date. I didn't have this issue back on XP either. Halp?

Guess no one has any suggestions..?
