- Update latest onboard VGA BIOS
- Update CPU ID (Support Intel Yorkfield CPU)
- Fix: Some of 1000 GB (1TB) HDDs will be detected size error.
- Fix PS2 keyboard compatibility issues
- First Release
From the above listed Bios versions list there is no specific fix for Win 7 64bit.
So a Bios update probably won't help but who knows for sure.
I'd check the drivers
first. The drivers may be all 32 and 64bit.
My Asus drivers were all 32/64bit so there were no different ones.
So this may not be the problem but a good place to start.
Of course get the newest driver
they have by date if newer than what you have installed or on CD.
