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.)

Check if all of the hardware is ok, reinsert RAM chips, check if the server gets too hot, could be a hardware issue.
