Hello all: This computer is in a teacher's staff room so there are 12 teachers using it at any time. It was working properly and stably until today when I tried to access a certain option in a program that is installed. I went to the edit menu picked the option and instantly without giving me any warning, the computer just rebooted itself. This happened again twice on the same thing. I uninstalled the program and installed it again thinking that might solve the problem and re-installed the program again. Mabey a little after halfway through the installation process, the computer decided to reboot again by itself with no warning what so ever. Any solutions?
