Windows server 2008 r2 blue screen of death?

Question

Iron

Dear toaster, today all day since the morning I have been observing a similar picture.
There is a server based on windows server 2008r2, used as a terminal server with document storage.
I will make a reservation right away, nothing was installed, no firewood was updated.
It works for 20-40 minutes, gives out a favorite screen of death and reboots. And so the whole day.
The work has already been temporarily transferred to another server, now there is time to pick this one up.
Please tell me what could be the problem?
The sfc utility did not issue anything, everything is fine.

At the cyberforum , they offer to drive memtest. In all topics, including the Microsoft forum, they sin on RAM.
Well, standard: with an eraser on the contacts of the planks: D

Answer 2

PS The Windows test for the operative in the standard mode did not give any errors, everything is fine.
