While most computer manufacturers and software companies provide some good troubleshooting tools, and while you can find even more online, would you not like the convenience of all the tools on a CD? That’s exactly what Ultimate Boot CD (http://www.ultimatebootcd.com/) can do for you. I utilize this tool on a frequent basis when troubleshooting, so I definitely think teachers can benefit from it, even for some basic troubleshooting on their personal equipment.
UBCD is a great troubleshooting resource available for free for a CD and even a bootable USB. What Ultimate Boot CD provides is a suite of your basic troubleshooting tools, such as BIOS troubleshooting tools, CPU stress tests (to check your CPU and see how much it can handle), memory tests, benchmarking tools, and hard drive tools. For hard drives, it contains tools for partitioning, cloning, and more. I can really appreciate these types of tools, as they make technicians’ work quicker, but also the common user can use this in many situations. A great tool!
