Hyper-v Server 2008 r2 - CRASHING

Server and V machines stopped responding. Plug in a monitor and see a box that says blue screen error.

I manually installed the chipset and the NIC drives on dells site. It’s still crashing.

Any Ideas?

The server has a X3450 2.66Ghz.
Disable ALL of the following in CPU options:

Clock spread spectrum
C1E Support
Hardware prefetcher
adjacent cache line prefetcher

of course watchdog should already be disabled too
