I had this same problem if you do a full installation of vmware tools it installs the vShield driver which caused my Windows 2012 servers to randomly reboot several times a week. I actually had to view the windows dump file using WinDbg to find that the crash was caused by a memory leak with the vShield drver. So, if you remove the current install of tools and just do a typical install, yes it would solve your problems because that driver does not get loaded on a typical install. Also with ESXi 5.5 Update 2 the vShield driver is not packaged anymore with tools, so it shouldn't be an issue going forward.
