Did my motherboard die?

Asus / K8ne-deluxe
October 24, 2009 at 18:50:48
Specs: Windows Vista, AMD Athlon 64/3 gig
I built my computer around 5 years ago. About
eight months ago it started making noise.
Then when you turned it off it would turn off
then you could here the power supply come
back on and make noise and the fans on the
computer run and it would sound awful. The
only way to stop it would be to turn off the
power supply itself. So we stopped using the
desktop for now and just used our laptops. It
has been approximately four months now and I
just hooked it all back up in our new house,
turned it on and no picture. When I turned it on
the monitor stated that it was connected and
working correctly. But as the computer booted
no picture (desktop) would show up and the
fan on the nvidia graphics card was not
turning. So I ordered a new power supply
(Aspire ATX-AS520W), graphics card (ASUS
AH4650) along with a wireless network card.
After installing all three new components I still
have the same results with the exception of
the power supply. It is quiet and turns on and
off like a good power supply should. But the
graphics card seems to not power up (fan
come on and spin) and the new D-Link
wireless card does not power up. Everything
else seems to power up, motherboard power
light comes on, all fans, power supply, etc.
Almost forgot, I also filled the last available
slot with a 1 gig stick of ram for a total of 3
gigs. I am starting to think my motherboard
died. Neither graphics card work or the
wireless card. I removed the battery, all ram
and vcard. I left out the battery for 20 minutes
with the power cord unplugged. Reinstalled
the battery, all ram and vcard. Still no power
up of vcard. Tried both cards and no power up.
Fan does not spin on either vcard no matter what pci slot they are in.

An ideas would be greatly appreciated.

not much of help, but only thing i can think to try: make sure all non-boot-essentials are unhooked from pwr supp, even the card-fans. pull all but minimal (1 stick) ram. use only min. ram, video and kbd/mouse and see if you get any response.
my guess, however, is the cpu is hosed. try heat-test.

Thank you for responding. How do I perform a heat test on the CPU (AMD Athlon 64, 2 GHz, Socket 754)

Sounds like you didn't even troubleshoot. All you did was run out & buy a bunch of parts that may or may not have needed replacing...not only that, but you put them all in at once!! You should have done exactly the opposite.

Try this:

- double check that the new PSU is connected properly - main ATX plug & 4-pin ATX12V plug are securely attached to the board.
- take out the new video card, the wireless card & all the RAM except one original stick.
- reinstall the original video card
- unplug the cables (both data & power) to all the drives (optical, HDD, floppy)
- unplug ALL external devices except for the keyboard. Use a PS/2 keyboard, not USB, & make sure it's plugged into the correct port.

Now try to bootup. Do you hear a single POST beep? If not, either your board or CPU are bad. To double check, take out all RAM & try to boot up...if the system doesn't beep like crazy, you've pretty much confirmed that it's either the board or CPU that are bad. Now you have to somehow determine which one.

BTW, you refer to the PSU as an Aspire ATX-AS520W? Aspire changed their name to APEVIA a long time ago. They claimed the name change was to cut down on confusion with Acer Aspire products, but IMO, the real reason was because they were getting negative feedback due to the faulty 500W PSUs they were pumping out at the time. There was a class action lawsuit brought against them.

That is a affirmative. The owners manual states Aspire. I do not receive any post beeps either way. I apologize for my ignorance but the computer is five years old and due for an upgrade as it is being past our daughter. So buying parts for it did not bother me as I planned to bring it up to date regardless. Is it possible to disable the post beeps in the BIOS? If so would this troubleshooting procedure still hold true?

POST = Power On Self Test

You can not disable it. The system runs a quick series of tests & then emits a single beep meaning "all is well". Anything other than a single beep indicates a problem & the number of beeps or pattern of beeps indicates what that problem may be. With all RAM removed, the system *should* beep continuously at startup.

Did your system used to give a single beep at startup? Do you have a case speaker connected to the board?
