Laptop's Pissing Me Off! Need Help Now!

[MistyBlue]

K, here's the problem. I run the game, play for a while, when I exit my sound goes out. Uninstalling, rolling back, and disabling/re-enabling the driver doesn't work. I have to go into safe mode, delete all the driver files, install a pristine driver and restart. It happens every time and it's getting on my nerves. Anyone got any suggestions for me? Also, if I try to start the game while the sound isn't working, it starts, but every few seconds, the  cursor jumps across the screen. What's the deal?
