The LED's on the board light up, so I know the board is getting power, and when I plug the keyboard in, the LED's on it light up, as well as the mouse. I have tried removing everything but the CPU/fan, video card (no onboard), and RAM, but I don't get even as much as a BIOS beep, and the CPU fan won't spin. I'm hoping the outage didn't nuke the CPU. Can anyone lend a hand? Thanks in advance! **edit** I am running Windows XP Home, Asus A8N-SLI Premium board, AMD Athlon X2 4400+ with stock heatsink/fan This post has been edited by lcplsexton: Aug 12 2006, 12:34 PM |

From what you are describing I would suspect the processor. You have tested everything else. Did you inspect the underside of the chip for scorch marks? Not that, that is definitive, but it can be a physical indicator.

Thanks for your response. I have inspected the CPU, and it shows no physical signs of damage (scorch marks, bent pins, etc.).
I'm not the most knowledgeable person about electronics, but to narrow it down before I go buying a whole new CPU, could there be any other source for this problem? Thanks again! |

Check the capacitors around the CPU. The tops should be flat and the sides should be smooth. If there are bulging that will indicate a bad capacitor. Also if fluid is leaking from them.

Do you have a meter to check the voltages on the mb?

I don't have a meter, nor is there any apparent damage to the capacitors, heatsink, or processor itself. I'm not too concerned with voltages because it is a brand new board direct from the manufacturer, and the system had worked perfectly up until the power outage. I've been doing more research, and it really seems the processor has gone out, because, as acklan said, I have tested everything else, including the RAM.

Well, time for an update...I got a new CPU, installed it, and hooked up ONLY the RAM and video card...STILL!!!!!!!!!!!!!!!!!!!! Won't turn on. As before, the LED's light up, but the CPU fan still won't spin.
So, is it possible that the power supply I tested in the other machine (which had considerably less power-hungry components) could have a bad wire or two, thus providing just enough power for the MoBo LED's to light, but not enough to power it up? I could really use some help on this...I'm one step away from sending it to GeekSquad...but with the money I've spent trying to fix it myself, I would have to wait even longer before paying them to fix it. Any and all help would be GREATLY appreciated. Thanks! |

To light the motherboard's LED doesn't require much in the way of power. A power supply not being powerful enough to start the machine doesn't stop it from lighting the motherboard LED. Getting something more powerful in the way of a power supply sounds like the way to go.
