ET + TS = problem?

So, I've been getting some strange problem last times, happens to me sometimes a week. So when I'm trying alt+enter in ET or vid restart sometimes It takes like 5 minutes. First I see like 1/3 of deskop, later 2/3 etc, on the end it comes to ET screen and 30 seconds for load a map. But mostly its like, Im typing vid restart and 10 seconds later I can play.
And now ts thingie. So sometime when my pc is working so 'fast' @ vidrestarting I can hear a error, TS error, I can talk and hear but cannot do anything on TS and when it happens I got like 2 fps in ET. Only solution is to restart TS and ET which takes 5 minutes :(

Have you noticed smth like this?
