Acer monitor come up no signal will not boot up on start
Check the cable at the back of the monitor and at the back of the computer. If the cables are in tight and you still get the no signal error message you either have a bad monitor or a bad video card in the computer.
Try plugging another monitor into the computer (borrow one from a friend, neighbor or family member if you don't have one). If the monitor does the same thing and shows a no signal message like your original monitor, then the Video Card in the computer is bad. If the monitors works, then your original monitor is bad.

Sound like a bad motherboard.You are getting the error because no signal is been sent to the monitor. Make sure the memory is inserted properly and firmly. Check all other cards and plugs are all inserted and firmly sitted. and try to boot the system, if nothing stll happen, you may have a bad motherboard

There are 2 basic reasons for the "No Signal" message.
If neither of these is the case, try hooking up a different monitor (if equipped, you can use an HDMI cable to your TV) to see if the "No Signal" message persists.If using a different monitor works, the issue is your Acer Monitor.
