I'm not sure how long it ran because I went to sleep but it wasn't more than eight hours.
Now I'm having trouble with my media.
It isn't so bad with audio but with video there's a lot of crackling noise and stopping as well.
It's like there is some other process running that's taking up a lot of memory.
I've run a virus check (nothing) and gotten rid of what little spyware there was but the problem remains.
