Hello! I have few problems with my gm8.1... 1. If I just run it and open any game it says: "No sound device detected. Sounds might no play." Game runs 10-15sec without sounds and then crashes, opens again and everything works fine. (This message shows even the game doesn't have sounds) 2. If I run it in "compatibility mode" and open game it says: "Failed to load game data. File seems corrupted." But if I press "OK", it starts and runs normally? 3. Few games opens everytime first in windowed, and after I get those messages ^, it goes fullscreen. So umm.. What's going on with my gm? This is very strange and it started suddenly do this. Earlier everything worked fine.
