My emx-mcp61p-avl has power but no display no beep. video card is new and compatible with my motherboard. RAM is new also.

Just because the ram and video card is new does not mean they work. But since you say it has power, I'm assuming it boots up all the way except the screen is not displaying.

If this is a laptop try the steps below.

Shine a flashlight on the dark screen to see if you barely see the icons on the desktop. If so, then the LCD Inverter is bad.

Plug in an external monitor and see if the display shows up on it. It can be any kind of monitor even the old big fat crt monitors as long as it has a vga cable to connect to your computer's vga port. If so that proves your video card is ok. The video will show on most systems when you reboot without you having to do anything. Some systems will require you to hit the FN (Function key) + F1 thru F12. Hold down the FN key then hit the correct key for displaying on the monitor (F1 thru F12). The correct key will normally have CRT/LCD on it or it will have the icon of a display.

If you see no icons by shinning a flash light and the external monitor works, then your screen is bad. If you see no icons by shinning the flash light and nothing shows on the external monitor, then most likely your video card is bad.

If it is a desktop try the steps below.

Try connecting another monitor to the computer. Borrow a monitor from a neighbor, friend, relative or co-worker and connect it to the computer. If the Borrowed monitor shows the display, then your original monitor is bad. If the Borrowed monitor does and same as your original monitor and does not show a display then your video card has an issue.

Pc not booting

If you hear the CPU fan turn on that doesn't mean the CPU itself is working. It can be only that the motherboard is getting power. Check all your connections such as monitor and peripherals and re-connect them. If you still don't get P.O.S.T. or ANY letters or boot options on your screen then your CPU is dead. (unless your monitor is bad)
Another easy diagnostic is using your ears. For example the pitch sound of the fan in some motherboards tends to lower and then increase because it's reading of the hard drive. This means your CPU is ok but either your graphics connection is bad or your monitor is.

No internet. When I turn my monitor on it show unusable signal.

First check the back of your computer to ensure the video cable is properly connected (Usually a Blue Square connector).

Second, check to ensure your PC is powered on and you can see lights on the front, or hear the fans spinning. Check the power cable to the pc is connected good.

Turn on power button and the fan comes on but the screen stays black and nothing else works.the computer is 2 months old,it did this at 1 month old.I unplugged it and pulled the battery and left it that...

Hello there,

OK this problem could be many things or could just be the input on the monitor so lets start at the beginning and go from there one step at a time making sure we check it all .

also i could use more information do you hear the hard drives going i know you said you can hear the Fans so we know the power supply is working on the Fans but is it working for the Hard drive's? System make and model if you have one, if you did a home build give me the system Specs.

Step: 1 Check the connections all the wires/Cables the Power cord make sure both ends are plugged in correctly, check the Monitor Cable Making sure the VGA is also plugged in correctly both Ends.
Step: 2 Check the input on the Monitor if you are using VGA make sure you are on the correct input and so on .
Step: 3 if you have another monitor to another PC or maybe an older one connect it and Test to see if you have a bad monitor .

if all these Steps Fail let me know and we keep going . i hope we can get this problem Fixed

Monitor will not turn on after booting computer

if you have onboard video try a video card that fits in PCI or AGP slot or try a different video card in place of the one you use
with everything else seeming to be correct this seems like the only thing you have not done
