If you have Thermal expansion installed you can make it so you don't have to manually start ANY computers up.
On the computer that's running on, build this:
That's a thermal expansion autonomous activator set to right click when it receives a signal. You should be able to replace the cable w/ a piece of redstone.
Then set "startup" to:
redstone.setOutput("INSERT SIDE W/ TORCH HERE",true)
shell.run("INSERT PROGRAM NAME HERE")
