I don’t think an eraser will help

You suspect that a computer is randomly failing because of a problem with the RAM. Where can you find the Windows Memory Diagnostic Tool in Windows 7? Pick two.

A) Control Panel / Administrative Tools / Memory Diagnostics Tool

B) From a toolbar button in the Event Log

C) From the Windows Boot Manager

D) From the Start menu, type “memdiag”

E) Just blow on the memory modules. That usually works.
