Graphical corruption and freeze in Windows 7 Guest

[steppres]

Windows 7 guest on any host OS using VirtualBox 3.0.4 will intermittently freeze and display graphical corruption onscreen. Resetting the VM will cause it BSOD during boot. The VM must be turned off and on again to regain operational status.

Does reducing the nr of virtual CPUs to 1 fix the problem?

Yes, I've reduced the CPU count to 1, also turned off IO APIC, PAE/NX, VT-x/AMD-V and Nested Paging in various combinations, but it still occurs. I've also noticed the same thing in my Vista SP2 guest too. The only thing that seems to stop it occurring is reverting to the Standard VGA driver that Windows provides.

I'm having this exact same issue if you need more log files.

I'd like to clarify that the only remedy is using Safe Mode. The guest will BSOD even when using the Standard VGA driver.

Switching to a single CPU has made things more stable for me. I have a guest that has run for almost 24 hours now.

Same Error occurs on Windows 2008 Server R2 Guest with vbox 3.0.6 on Windows 2008 Server host. I didn't have this problem on a Windows 2008 Server guest.
