Hi all, been awhile since I posted but anyways, I have a dell p4 that was dropped off a bed to the floor so the first thing I thought to think is take it apart to see if anythings loos but nothing seems to be, I have took out most parts looking for cracks and loose connections but can't find any. well the motherboard has a power light lighting up on it so I assume it's getting power, when you push the power button it highlights a yallow color, but it has an arrow that points to the power button thats not lighting up but I'm not sure if it's the power light or hd, my fan is not coming on and the screen says nothing? thanks for all the help
