Flash player starts jittering/lag after standby mode.

(computer: sony-fw11m; os: windows xp-x64 edition; browsers: firefox/ie)

My system isn't happy with the flash player when it comes from the standby mode. The flash player then starts to jitter/lag and produce clatter noise whlle playing any flash media on the internet (the rest of computer is not effected).
I've tried reformatting/reinstaling everything I could think of - driver/hardware related but at the end nothing avails - I have to restart operating system every time I turn it back from the standby in order to run flash player flawlessly again.

Any ideas what can be triggerring this odd flash player behaviour after standby mode? Thanks all.
