If you have access to the ESXi Host you could get a DSA (HW and Software logs) to verify if the problem is HW or Software (VMware).
Attached is a link where you can get the DSA from the actual computer manufacturer (Lenovo).
From a Windows PC where under the DSA you should run from the command line the following:
lnvgy_utl_dsa_dsala7k-10.5_portable_windows_x86-64.exe --vmware-esxi root:email@example.com
yyyyyy is the root passsword
xxx.xxx.xxx.xxx.xxxx is the ip of the ESXi Host
A Lenovo Support directory will be created on the C drive of the PC, please zip this directory.
