Windows 7 Serious Video & Audio Issues

OK guys..... I know that there are a lot of other threads that touch on the issues of video and audio problems but i see no solution's....

I have a fresh install of windows 7 RC that i installed yesterday and i am having very serious issues..

OK I hope Microsoft is Looking into these issues..

Prob#1
The video is not as it should be... it goes blank (BLACK SCREEN) powersave or No signal right after it boots and gets past the windows logo.
downloaded and installed the latest Nvidia Drivers from the web and still does the same thing.
also something funny that its doing is showing the refresh rate @ 59mhz instead of the 60 that it should..?? when i change it to 60 the screen goes blank and returns at the default of 59 after 30 secs...???

Prob#2
The M/B integrated audio card was detected automatically by windows and a driver was installed. its a Creative X-FI extreme or something like that, but the rear audio ports were not working
when i plugged in a set of headphones that i had into the front port, they worked to my surprise...
soooooooo ....
I uninstalled the drivers that window installed automatically and downloaded the windows 7 driver from the creative website.
upon installing the drivers it gives me an error and says that there no compatible hardware detected.
I went through about 5 or 6 of the drivers from there web site with no luck..8(

I even let windows 7 download the audio drivers from the net automatically and install them... no luck.

Now the audio device doesn't even show up on the device list and doesn't work at all.....8(

pleas See the attached Computer Report...
