No Luck in Fixing System After Burnt Power Supply


I'm completely stuck and could really use some help. Here are the specs:

Albatron K8X890 Pro Socket 939
AMD Athlon 64 3200
1GB (2 x 512MB) 184-Pin DDR 400 (PC 3200)

I installed a used modem in my computer and after about 15 minutes of trying to get it to work, the signal to the monitor was lost and I smelled burnt rubber in the room. The first thing I thought of was the power supply had gone out -- but hopefully didn't take anything along with it.

I removed all peripherals, SATA hard drives and anything in the IDE slots before starting to diagnose.

I replaced the power supply and power cord. Still no signal the monitor and a single, long beep from the motherboard when powered on.

I replaced the motherboard next, with the exact same model. Still no signal and same long beep.

Next I replaced the CPU, this time upgrading to an Athlon 64 3400. Still no signal and same long beep. Replaced the RAM. No signal and still a single beep. Sent back the CPU and ordered an Athlon 64 3500, but still no signal and same beep.

I'm lost at this point because it's practically a new system and yet still no signal. Where can I look next for the cause of this? Any tips on diagnosing better?

Sound like it's the Memory.

I forgot to mention that I reset the CMOS on the new motherboard as well.

Perhaps I ordered the wrong RAM? I originally had Corsair dual channel CMX512-3200XLPT (2 x 512MB) but since this is no longer available I ordered Corsair dual channel CMX512-3200C2 (2x 512MB). It should be compatible though.

I tried swapping around sticks like crazy but still the same results.

What does the 1 long beep error code mean anyway?

Have you tried a different monitor? I'd also try a different cable to the monitor.

The fact that the power supply fried means that a lot of current was being drawn through the system and could have damaged anything and/or everything. Every single original piece is suspect at this point.

You may have made a mistake replacing the processor and the mobo separately. I have seen cases with Athlon processors where the processor failed in a fashion that would take out the mobo as well.

So, consider this scenario: your athlon failed and induced a failure in the mobo. You replaced the mobo, then stuck the bad athlon in - which killed your new mobo. Then you changed the processor, but the mobo is bad. Then you did all these other things...but the mobo is bad.

I've seen it. It has happened to me. It sucks, royally.

But, from what you describe, something like that has happened to you too.

Maybe you should just buy another computer. I have a Commodore PET 2001 I could let you have for the right price.

Yeah that's the only case when I think giving the box to "trained personnel" makes sense because
  • they have testing instruments you probably don't have
  • if they damage your box further, it's their fault and they have to compensate for that.
Having the power supply die is the severest failure I can think of. So if you can spend some bucks on that have your box tested by professionals. I had the same experience jiml8 mentions some time ago and it looks quite like you're having that too now.

Oh and don't let masonm fool you. What he offers is crap. I have a ZX Spectrum here I'd give away for the right price. I mean what can you do with a Commodore PET???

I agree that perhaps it's time to let a pro have a look at it.
