Compaq 6005 pro

I have a Compaq 6005 pro and am getting a 4 beep error code. At HP's site it say possible power supply or motherboard.

I've blown it out. tried a different stick of RAM that I know is good. I was going to try the paper clip test to test the power supply but it doesn't have the 24 pin connector. Looks like it's a 6 pin? Is there a way to test this power supply? Are there any other things I can test to see whats going on?

Sorry, I know my way around PC's some but not a pro by any means.

Any help would be appreciated.

Thanks

  1. It appears from a Google search that unit doesn't use a standard power supply but a custom proprietary PSU. I'm not sure there's a way to independently test a non-standard PSU. Is everything but memory and power disconnected from the board? My feeling is it's more likely a motherboard problem but only testing with each part can tell for certain. Perhaps re-seat the CPU and test again.

    Did anything happen before this or did the problem come out of the blue?
  2. If a part is to be replaced, that system won't fit a standard board either because of the unique power connection. The only place you'd find replacements for either is ebay.

    It's up to you to buy a component to test with without certainty it's the culprit or look for a new system...
  3. Is this a MT.

    The 6005 Pro uses a proprietary power supply connection , it's a 20 pin power connection instead of the usual standard 24 pin connector.
  5. Thanks for the replies...

    I found a replacement on ebay. The part and spare #'s
    DPS-320JB A
    503377-001
    508153-001
    Its a full tower not the MT

    Nothing happened out of the ordinary. I just turned it on and got the 4 beep error.

    I hate to purchase the PSU and it end up being the motherboard. Is there anyway to narrow it down to one specific part that has failed?

    Thanks again

    The only way to be certain is to test with different components. At the shop where I work we'd ordinarily try a different PSU using a standard PSU we use for testing but that won't work here due to the proprietary design.
  7. That's what I was afraid of SchizTech. I guess I will call around and take it into a shop and let them do some testing.

    Yep. That's the same one. Thanks SR-71 Blackbird

    Say it is the motherboard. Is replacing it just a matter of replace plug and play? Or is a whole process of matching something with the hard drive? Again, I'm not a pro.

    Thanks again
  8. Welll I replaced the power supply. All the fans come on now but it doesn't seem like it's booting up. The HD activity light doesn't flicker like its doing anything and the monitor shows nothing other than after I turn it on a few seconds later its says its going to sleep.
    And the HD does spin up but no post beep.

    Any ideas now?

    thanks
  9. Well it sounds like the board might be gone too. Since that's a proprietary PSU you'll need the original HP board (maybe ebay, nowhere else would have it). It should boot correctly, though Windows may re-install the drivers on the first boot.

    However, there are a few troubleshooting steps to go though. First re-seat the RAM then try one stick at a time if that doesn't work. Make sure everything but the essential components are disconnected.
