Yes if there are error on the system you should most likely hear a beep most of the time when there is no beep it is due to bad ram. Some times beep codes can't detect bad ram and your computer will not boot.
Open the computer up and see how many ram chips you have if you have more than one take the one in dimm slot 2 out. There should be small writing next to the slots 1,2,3,4 or Dim 1 dim 2 ect ect. you always want to keep slot 1 with ram so start by pulling out the ram out of slot 2 and turn your computer on. If your computer still dosn't post pull the ram out of slot 1 out and insert the ram that was in slot 2 into slot 1 if still no luck it's most likely your board but the best way to test this is to know that you have a good working stick of ram you could purchase one and if it dosnt work bring it back ... theres also the chance of your video card being bad but there is usualy a post code for it (beep code)
if you have no clue on what ram looks or how to open your computer just google for installing ram on a computer and you should find step by step guides

My Acer M5640 desktop lately when start up, after the beep nothing appear on the screen, hv to turn off the power and try again, somtimes it will be ok, what's the problem?


As the computer gives the beep it shows it is working, it has pass the Power On Self Test.

Your problem is a loose connection, either at the Graphics card slot or on the monitor VGA ports.

Check the VGA ports at both the Graphics card and at the monitor. Also clean the RAM modules of dust and reinstall.

Take care!

M5640 power comes on no video. changed motherboard and power supply


I assume you are using the integrated video, (on board). With a new power supply and motherboard you have eliminated all but the monitor. Try a different monitor. I have also seen a case where a computer tower worked fine in one setup with a flat screen, but when hooked up to an older CRT monitor it would not display because of the resolution settings.

I am working a computer an Acer Aspire M5640 desktop with Windows Vista Home Premium. The system would not boot. When I took a look and turned it on and the monitor has "no signal." There is no splash...


try to boot first in bios, if it work normally restart and press F8 and start in VGA mode select screen resolution to 800 by 600. if still not work re-install windows vista operating systems.

My 19mvwk is saying no signal going to sleep


Check the data cable is properly fixed. Can you hear the beep sound while booting. Check the ram inside the cpu.
