This problem occured here on Hetzner servers-Yes it's helps.
The VM is booting then blue screen of death.
We have one server which runs great with a i7 2600 and ordered a new one with a i7 975 and nothing worked on this....
Until the blue screen where I found out about with error stop 0*0000005d that it also exists in other virtuailztion softwares...
Now we just cancelled this server and bought another with a i7 2600 again...
Will date up...
