Randomly shutting down
Hi there people.. Me again
I have noticed computers across the school are randomly just switching them selves off or restarting. i can't find anything in the logs about why they are. it just seems to be attacking certain rooms, not random computers . Please could someone help me =-)

You sure it is random (ie - you've actually seen it happening) and not just that kids have been reporting it.
If you've seen it happening)
Have you recently put out a new image to most of the machines you believe to be affected?
If you haven't and it is just a reported problem)
Is it anything to do with the p[ower management settings (within BIOS not windows) of the PC's themselves?
Just some ideas to be looking at anyway - don't forget it is Friday the 13th, could you have a techie friend who is playing a practical joke?
EDIT - This post assumes you've just noticed this!! What FN-Greatermanchester has just added would make more sense if it is an ongoing problem.

They are probably overheating. I would check the airflow and possibly put an extra fan on the back of the case.

We have this as a heat issue. Some of them just refuse to play DVDs Other just shut off.
We've got air con in all the e-learning rooms now (appart from one new one).

I immediately thought overheating or psu. I don't know if it is likely but could something like a voltage surge affect the power supplies, some worse than others. If I have a machine that is constantly resetting, the first thing I check is the psu and that normally is the problem.

Hi.. Its not just one computer its about 5 all at once

Which is why I wondered if some external power glitch might have affected the power supplies. Try taking the psu out of a good machine and trying that.

If it does turn out to be heat based you may want to clean out the heat sinks on the machines, I did a write up (all be it themed) of the methods to clean these out.
It could also be an issue with the points or phase that those specific computers are on, you might want to try moving one of the pcs to a different point and seeing if it still affects it.

I have found out what it is.
Remote shutdown . . How does this work
15th June 2008, 11:48 PM #10
From the CLI.
shutdown -s -m \\machinename

- Rep Power
Hello, my name is JP Freeman and I am an ICT technichan at UCT (University of Cape Town).
I recently had this same problem with some of my computers, we have been told by some students and teachers, because of this I have decided to investigate this and have found a few students to be using it.
I have also found students accessing Task Manager, Regedit and the Command Prompt, is there anything I can do to stop them without disabling their accounts? If they got past our Ranger and group policies is there a way to stop them?

Why did they get past group policies - I would double check the settings they have because this is a big no no. Either something isn't working right or your GPO's are too relaxed
