My emachines ran fine last nite-tonight I get a 2-3 second beep with 2 flashes of the power button no power to monitor to see any messages or ability to get into anything. Fan is running. I believe it is W3644.

Try remove the battery and power cord. Then press the power button and hold it down for 10-15 seconds. put everything back in and push power button once. See if this helps it come back on. If not, you may have a bad monitor, backlight, or video output from the motherboard. Hooking the laptop up to an external monitor will help isolate that problem as to what exactly is causing the problem. I hope this helps! :-)

If its a flat screen monitor ?

eMachines flat-screen monitors offer high quality at low cost. eMachines flat-screen monitors are compatible with most brands of PCs. Issues with eMachines flat-screen monitors can arise from faulty power sources, cable problems and incompatible settings. These issues can be resolved by testing step-by-step each possible cause.

Plug the computer's power cable firmly into a working AC outlet. Press the computer's power button.

Check the LEDs on the front of the computer case to confirm that the computer receives power. Plug the eMachines monitor's power cable into a working AC outlet. Press the monitor's power button. Check the LEDs on the front bezel or power button of the eMachines monitor to confirm that the monitor receives power. Orange or blinking LEDs indicate low power or no signal. Green LEDs denote a working connection.. Perform a monitor self-test. Switch off the monitor. Unplug the video cable from the monitor. Press the eMachines monitor's power button. An eMachines logo, Windows logo or "no signal" message indicates that the monitor is working properly. Plug the eMachines monitor's video cable into the video port on the computer. Attach the monitor's included DVI-to-VGA adapter to the monitor's VGA cable if your computer has a DVI port (15 or 25 pin-slots with 1 side slot) in place of a VGA port (15 pin-slots, no side slot). Press the eMachines monitor's input button to change the monitor's setting to match the computer port used. Set your monitor to DVI if connected to your computer's DVI port. Set your monitor to VGA if connected to your computer's VGA port. Connect the eMachines monitor to a known working computer with a known working video cable if the problem persists. Contact Gateway, eMachines manufacturer, if the monitor issue is not resolved. Hope this helps.

the beeping is coming from the cpu.

1 unplug pc
2 pull out ram chips
3 use an eraser to clean the gold, yes thats gold

what happens is the gold on the ram oxidizes and does not connect properly and can go bad but cleaning it with an eraser sometimes works. take a cpu that is working unplu it pull the ram and you will see the same thing your other pc is doing.

4 reinstall ram (correctly)
5 boot up cpu
6 please vote.

Sounds like the motherboard. Do you get any Beep codes?

Ok, follow these simple steps and your PS3 should display properly on the TV.

Step 1. Turn your PS3 onto standby (red light on)
Step 2. Press and hold the power button. It will beep as soon as you press it then beep again 5 seconds later. Release the power button
Step 3. Wait for the PS3 to restart.

This resets your video resolution back to standard definition. You should now be able to setup your video settings correctly using the PS3.

it sounds like your ram or video card is not functioning. You can try some different ram and video card and that is where i would start. This is probably not going to be an easy fix so be ready

1: Check the cable connections for the VGA or DVI cable at both ends for a secure connection.

2: There may be a button on the bezel of the monitor for input source to switch between VGA, DVI, or HDMI. While the monitor is on, press that one or more times waiting 2 or 3 seconds between presses to see of it finds the signal.

I turned on my computer and the monitor displayed this message on the screen "going to sleep no input received". I checked the power cord and unplugged it, nothing. No lights are flashing or beeping sounds. The CPU is working just fine, anyone have any idea what to do

Couple things to check. First, check with different monitor. Their monitors are usually build by KDS and I think there was a bad series out there. Also check for any beep codes through speakers on startup, this can tell you bad ram or bad video out. Also try unplugging computer and removing CMOS battery inside (watch like battery). Lastly, If non of the above, a bad processor will allow the computer to come on but no beep, no boot, no nothing but fans and green power light. Hope this helps a little.....
