Gateway ML3109 doesn't come on

Hi. I have a Gateway ML3109 that when you hit the power button, you hear the fans, hard drive spin up, lights turn on, but nothing happens. The screen is blank. Tried a different hard drive and I plugged in a external monitor to see if it was the monitor, but no luck. The only light that stays on after the initial startup is the hard drive light.

Any thoughts?

It does seem like it is a video card issue. If it is an onboard video card you will need to replace the motherboard.
This is the method I use to troubleshoot my laptops when brought into the shop for repair/diagnostic:
1. Capacitor/Battery check:  
A. Unplug the ac adapter. Keep ac adapter unplugged.
B. Remove the battery and keep the battery unplugged.
C. Hold the power button down for 15-20 seconds. (Nothing will appear on the display and none of the lights will light up.)
D. Release the power button and plug in the ac adapter ONLY. (Note that a power indicator light should be lit on the AC Adapter when it is plugged in).
E. Normally power on the laptop.

2. If it Does Not Power "ON":
A. Check AC Adaptor: a power indicator light should be lit ON THE AC ADAPTER when it is plugged iN. If no light: replace AC Adapter.
B. If it does have a light, test the socket where AC Adapter plugs in:  If you "wiggle" the cable and the POWER LIGHT ON THE LAPTOP flickers you have a bad power socket on the motherboard.

3. Powers ON and Video is available: Test Memory and hard drive.Reset BIOS to default settings.

4. No Video? Plug in an external monitor. Test.

5. Still No Video? Disconnect AC Adapter and remove all peripherals: remove CD/DVD drive, Wi-Fi, Bluetooth, modem, printers, anything plugged into a USB port, memory. Restart. Test. No Video?

A. If it beeps: leave one memory stick and alternate.No video: Bad Video card (if it is integrated to the motherboard you must replace the motherboard).
B. No beeps: Bad motherboard or CPU.

I looked it up, you should have an ATI RadeonĀ® Xpress 200M graphics with
Up to 64 MB of HyperMemory" but it does seem to be part of the motherboard according to gateway: 4006148R - Motherboard UMA w/ATI RC415MD w/o 1394 (FRU)

Ok .... I just confirmed. It is integrated onboard. See the screenshots below. The fact that even plugging in an external monitor does not work eliminates the posibility of a loose video cable....

I was leaning towards something with the board, but wanted a 2nd opinion. I think your correct saying it is a card issue, therefore having to replace the whole card.
Thanks
