Overheating can be the cause. I'm not sure why you didn't post the OS you are using and the specs of the computers in question.

If they are running Ubuntu, update the kernel to a newer version, since one of the last versions has a bug that causes failures.

If there are other identical machines with no problems, get them a UPS. Most of these kind of hardware problems are caused by dirty power.
