I have the problem with Core 2 Duo E8400 on Asus P5E-VM DO (iQ35). The Hyper-V role was installed only while VT was disabled. When VT was enabled, I had a "blue screen of death". It's right for Windows Server 2008 and Server 2008 R2. BIOS latest 0902. For prossesor E6320 all work good. With Intel drivers for iQ35 motherboards all the same. Is this chipset iQ35 or BIOS problem ? Is anybody have such problem with Intel motherboards?
