BSOD on multiple Win 8 Machines Dell ntoskrnl.exe Ntfs.sys

[timinggame]

Hello,

My company purchases Dell Optiplex machines,
these BSODs have been happening about monthly on 5-8 machines all purchased at the same time which makes me feel it's not a hardware issue but a corrupt system image possibly from Dell?

Here are two computers BSOD files.
