Windows 2008 R\2 VM Host crashing

I have a Windows Server 2008  enterprise R2 server that has crashed twice so far within a week. Server hardware is HP DL385 G6. The server is a VM host and is in a cluster of 3 servers. The failover's are working properly (VMs get ported over and load balance between the other two servers.)
