Sounds like you may be getting hit with the C1e processor state problem. There is an update rollup for HyperV 2008 R2 from August that fixes 3 problems, including yours.

to clarify:  the server stops working once a week?

please check event logs and report events that occur when this happens

Also, I have noticed that most crashes are caused by malfunctioning device drivers and kernel modules. In case of a kernel error, most computers running Windows do not show a blue screen unless they are configured to do so. Instead these systems suddenly stop responding or reboot without any notice.

There is another free tool that can helps here named WhoCrashed that shows the drivers which have been crashing your computer with a single click. In most cases it can pinpoint the offending drivers which have been causing misery on your computer system in the past. It does post-mortem crashdump analysis and presents all gathered information in a comprehensible way.

WhoCrashed relies on the Windows Debugging Package (WinDbg) from Microsoft.
Download it and check if this will helps you or not but I am sure it will help you because I have used it on my environment before and it helped me on solve the problem:
