I am working on an HP Pavilion 524w for a friend and it will not boot. Here are the symptoms:

No video at all so I cant see any error codes or get to BIOS

It does beep...1 long followed by 2 short, then it makes a groaning beep..weird

Power seems to be ok, meaning there is power to the unit, cd door opens, lights on, etc.

The user complained the pc was making a very loud noise over the past few days but still worked, when it stopped working and no noise he broght it to me....lol

Not sure where to begin troubleshooting this, as I have never seen symptoms like this.

Thanks for any advice......
