DMV/TSQL to find out basic hardware information of the SQL Server including when SQL Server started.

Please use below code:

However, please be advised that it can not tell correct information around virtualization.  For example, it will show Hypervisor even if SQL runs on a physical OS where Hyper-V is on. So use this query only when you do not have sufficient access on underlying Windows Operating system to get these information directly.
