Question about HP (P2074-69003) Motherboard

1 Answer

HP Media Center PCm270n

When I turn on my computer, fan goes on lights come on and it sounds like it is going through boot-up. However, nothing shows up on my monitor (black screen). I have replaced the video card and no luck. I also have a 4 slot USB II card in a PCI slot that had active ports. Now when I plug something that should light up when I plug it into any of the ports, nothing works.

    I don't know who posted this, but when you click on "system" you are taken to Best Buy! That's either an error or or someone misusing this site.

    I have the HP PAVILION DESKTOP PC A6000N and when I turn it on, the monitor said no signal. The tech at HP told me to turn the pc off, unplug it, take out the memory cards, turn it back on and it should make a beep sound. Well it wasn't so he told me that it's the mother board that need to be fix. Is this correct? Could anyone suggest what I should do or if I need to replace the motherboard, what type should I replace it with?

Continous beeps usually mean the motherboard or the power supply, Try another power supply first and see if it will boot, if not the motherboard is faulty, if the prossesor was faulty you would no beeps the fans would run but nothing on the screen. hope this helps.

It sounds like you have a board that is not booting at all. Remove everything from the board except the system RAM and CPU and switch it on. If it boots now, shut it down and then replace each individual item one at a time, booting the machine after each item is refitted/connected until you fit something that prevents the machine from booting. Pay special attention to system RAM sticks by removing them/it and refitting it as bad connections in the RAM socket can also cause a boot failure but removing and refitting the sticks usually cures this issue.

My hp media center m7160n computer powers up, has a definite fan sound, normally the fan sound diminishes and the computer boots up. For the last several months, the high speed fan sound would not diminish...

How did you clean it?
The last one I worked on had the fins of the Heat sink totally blocked with dust. This will make the fan scream trying to push air thru the heat sink to cool the processor. If it isn't cooled it will shut down in short order.
You must BLOW it out. Use a pressurized air can. Better if you have a compressor with a nozzle.

The other issue may be the interface between the CPU and heat sink is defective. Heat sink moved or become loose.

Of course by this time the processor could be dead also.
