Error when resuming from standby (ASUS SK-06903-XMA)

Hello. I have recently installed Windows Vista Beta 2 and I have a problem
when resuming from standby. Everytime it resumes, I get a blue screen error
and after rebooting I get a message telling me there is a solution to my
problem. This is what Vista tells me:

"The version of ASUS SK-06903-XMA that you are using, created by Microsoft
Update Website, is not completely compatible with this version of Windows.
Your computer is missing updates that can fix or prevent the problem you
reported.
Click the following link to install recommended updates from the Microsoft
Update website now:

Microsoft Update Website

Note: If you have not installed the latest Microsoft Update software, you
will be asked to upgrade and restart your computer before you can use the
website. After restarting, go to the Microsoft Update website. Click Custom
Install, select optional software updates from the left, and then install the
ASUS SK-06903-XMA updates."


I follow the instructions but I can't see any ASUS SK-06903-XMA update, nor
I see the "Custom Install" or "Optional software updates". Windows Update
just tells me all updates are installed.

Any suggestion regarding this? Also, a search of ASUS SK-06903-XMA over the
internet returns no results....

Thank you in advance!
