Re: emachine destop not recognising acer lcd monitor
It sounds more like the computer isn't starting up. The "no signal" message is coming from the monitor itself to tell you it's on but there's nothing coming in to display. Normally no special drivers are required for the monitor, and you'd see at least the computer maker's splash screen and BIOS messages if the computer was starting up properly.
You'll need to determine what is keeping the computer from starting up. Make sure it's getting AC power and that the power light comes on when you press the front panel power button. You may need a power supply. If the computer comes on but doesn't boot you may have memory problems or trouble with the motherboard. But your monitor is working properly.

Is it the screen or the laptop?
Have you plugged an external monitor to see if its booting?
If it is booting with an external monitor, you may need a replacement screen (google your model and replacement screen)
If its not booting, you could try this.....
Did it work before?
Have you installed any new hardware or software?
Do you have any USB devices connected?
If so, remove and try again.
Try going into the BIOS to make sure the hard drive is recognised.
I hope this helped. Good Luck and have a nice day.
look first go to your device manger and see if it is connected or not and if it is connected you will have A software problem if not conntact me again and i will tell you exatly what to do see first if your machine can red the dvd in the bois or not thx
If you are comfortable with opening the case, you can try this: Unplug the power supply, make sure are constantly grounded (touching metal)remove add-in video card. Locate the "Clear CMOS" jumper (usually 3 pins in a row with two shorted via a plastic jumper). Remove the jumper and short the other 2 pins (if originally pins 1-2 with 3 open, short 2-3 with 1 open) for a few seconds. Then replace on original pins. Plug monitor into motherboard video port and power on. If it works, you can leave as is or try to re-install your video card following the same precautions when opening the case and probably changing BIOS settings to utilize the add-on card.
E-machines had had a long history of bad power supplies. I've seen many of these machines go bad and when they do they take out the video chip (Nvidea) with it, usually shutting down the whole machine. I've never seen one operable. You might be able to insert a video card.
