Your computer doesn't turn on then check the connections. Does your monitor turn on, but not your tower? Could be the power strip (if you have one) is not working properly, not plugged into a wall outlet or not switched on. Try switching to a different wall plug. Make sure the plug is securely plugged into the computer. Check to make sure the switch in the back of the computer is on.
If all of the above doesn't fix the problem, switch the electric cable with a known working cable.
