So my trusty old desktop has bitten it...

WinFast 6150K8MA-8KRS (Socket 939)
AMD Athlon 64 3200+ (Venice)
2 x 1024MB DDR-400
Maxtor 160GB HDD (8MB cache)
350W PSU

I have stripped it down to barebones: motherboard, CPU, RAM, PSU.

It still doesn't POST. I don't have access to another Socket 939 motherboard or CPU to try and swap to check what's the problem. I've tried each DIMM in each of the 4 slots. I've tried swapping out the PSU with another (known-to-be-working) one.

No joy.

Any other troubleshooting tips?
 
that vintage ,,,,i'll be suspicious of the capacitors on the motherboard...check the ones around the cpu socket to see if they are bulging at the top or leaking any substance. if they are suspect and you are still desperate, take ti to a t.v. repair place or similar to have them replace the capacitors (or anybody that can solder reasonably well)
 
Does your motherboard have a Northbridge heatsink and/or heatsink/fan - it's usually about 4cm x 4cm size, with a low profile fan which connects directly to the motherboard via a small 2-pin connector, usually white. The one on my board looks like this:

When you power on does this fan move if you have one? If not, then you've probably fried the Northbridge/Southbridge.
You can try replacing it, but they are helluva difficult to find - I think I saw some at Esquire last time I was there, about R60, but you need to check if they fit your board first.

My Gigabyte 939 had exactly the same problem - just stopped one day, and I found out that the dust had knackered this fan, it stopped, and the components overheated to the point of failure...
Luckily, it was within it's 3-year warranty, so I popped it to Rectron and they swapped it out, no charge. Fitted the board again and it booted no problem...

Try and see if there is still warranty available on your board and swop it out?

You can also try removing the motherboard from the case and check if it boots out of the case - may be a short? If so, isolate the board from the case using small thin rubber or nylon washers...

I've checked that already. And why take to a TV repair place? I've replaced caps on motherboards myself numerous times :D

No fan on northbridge, only heatsink.
 
When you press the power button, is it turning on, eg. are the fans of the cpu and psu running?
 
Go to Checkers, buy a black refuse bag, put it in and wait for the blue truck :p

Hi Sn3Rd

before you throw away that motherboard , try this it might work for you
1) un plug your PC from the wall , and remove the power cable from case.
2) strip the motherboard from the case
3) Remove cpu, memory from MB
4) get some tin foil and place the motherboard on it for about 20-30 min,

( the reason for this is that your motherboard might have got a Static shock and you needs to discharge , this is a very common problem especially in Summer , and we have been getting some really hot dry days )


hopes this works for you
