Assistance required please - FSX- SP1 problem

Hi
I have installed FSX + SPI patch as suggested by Phil Taylor. Suggested tweaks made.
FSX running beautifully with all sliders fully right(except water -set on1+), unlimited frames (60-70fps)
no bloom or shadows. On my machine I cannot detect stutters or blurries that I cannot live without.
With my system specs I am amazed with the performance of FSX that I am getting.
However I am experiencing 2 problems that I have been unable to cure by adjusting my settings in FSX and altering tweaks in config file.
1. For some reason in main cockpit I am on occasions when eg move mouse to heading bug or select GPS I get a white screen for approx 1-2 seconds. That disappears and I am able to change heading or select from gps/radio stack etc toolbar.
2. I am getting when comm and nav etc are on in radio stack intense sound distortion/interference at times especially between signal ident from vor or ATC etc. It does not matter if ASV6 is being used (thought that may be the problem).
Any assistance/advice would be greatly appreciated.
