Screensaver Problems on Macbook Pro (2010) after Lion Install

hi,

macbook pro (bought march 2010) fine until installed lion.

since been acting weird. crashing. audio output failing. not waking after sleep. i've tried applejack auto pilot, no luck.

1 of weirdest issues when screen saver has been active. have move cursor around reveal grey background can find login button , password entry.

i'm scratching away screen saver reveal background. see attached.

ideas? else had such problem?

thanks, andrew
