Depending on the manufacturer of motherboard, usually 4 beeps indicates a memory error.
To check, do the following.
Warning: try to do this in an area free of static electricity.
1. Your user manual should show you where the panel is to access the memory. You will beed a small screwdriver (or sharp tip of an old steak-knife) to get the screws off.
2. Most memory errors are caused by memory that needs to be "reseated". You will see the memory looks like it is lying flat on the mother board. There are two clips on the side that should be pushed back to allow the memory to "pop" off the rail.
3. Gently, but firmly push the memory back down into place. It should quietly snap back into place.
4. reassemble panel.
If this does not fix the issue, there is a more serious motherboard issue. You will need to call the Manufacturer (Acer) to determine if the system is under warranty for replacement parts.
Hope this helps.

just leave the motherboard, power supply and processor intact, try turning on the computer with out those components mentioned. see if you get a beep sound before it turns off, but if not the most logical part that needs to be replaced on this type of problem is the power supply if that doesn't work the next thing to do is replace the motherboard. hope that helps
ok, there could have been a graphics issue in the bios caused by the windows graphics drivers, heres what you could try........... remove the power cord from the back of the machine, remove the side panel to allow access to the motherboard, you will see a battery! take it out for 10 mins and push the on/off button a couple of times, this will drain any remaing power from the motherboard, after 10 mins the CMOS should have cleared so you can replace the battery, plug in the power and turn the machine on hopefully you'll get a signal
Turning the power off with out going through the shut-down process will sometimes trash the hard drive making it un readable. To force format of hard drive hold down the shut down, send, shift and quick routing keys at the same time then turn power on. This will format the HD. When finished the display will show "Factory initalize complete" "please power off" NOTE you will lose every thing on the HD including the demo song.
hold the power button for 10 seconds it turn off ur cpu and then start the cpu and hold F5 key u get windows boot menu select safemode try to login after login check in the controlpannel poweroptions chek in advance option see the menu down wheather it is in standby then change it to shutdown and apply the setting. and check it out it may work r else please try to repair the os.
