Problems with half life 2

[Pokeo]

I think this is the place to post this. During the time I play it plays smoothly almost no problems at all my only problem is it randomly locks up and like voices constanly repeat them selves for a few seconds than the game kicks back to normal again. WHy is it doing this?
