Dead 754 board? Help!!!

My Chaintech VNF250 / A64 3000+ / AIW 9600XT computer bit the dust last week. It was running just fine and I went to work. I came home from lunch, and it was off. I went to power it back on, and the CPU and PS fan spun for 1 second, then off again.

I switched off and on the power supply, and it would do the same thing. A faint noise when powering off the PS, then fans for 1 sec, then dead.

So I ordered a new power supply, which came today. Put the rig together, and this time NOTHING. No fans, no POST, nada. Sh1t! It must be the motherboard.

A few questions from you knowledgable folks.

1. This was, and still is a budget computer. Should I just replace the dead (both circuit wise and platform wise) Chaintech with a 939 board and new CPU? This would cost a lot more, but just wondering if there would be a big advantage going 939. I did just buy another 512 memory, so I do have matching DIMMs (unless the old one fried)

2. If I do go 754, which board would you get?

3. How do you go about testing for dead parts (like RAM, video card, if you don't have a functioning board?

Sorry for the stupid post, but I'm kinda in a hurry and need this computer up FAST.
 
It's interesting that people always order a new power supply first, when a good one costs more than a budget mobo. 😉

It's also funny how systems never die when we're there to watch.

Don't tease me, help me 🙁
 
Sorry, I wasn't teasing you. Just making a general observation, tongue-in-cheekish.

I assume the fan on the replacement PSU, at least, was running?

If the PSU was live and plugged in correctly, and there are no signs from the mobo, and none of its fans are running, then the options are basically: a bad short, probably against the case somewhere, or the board is shot. You've got both plugs in, right? The 20/24 pin and the 4 pin?

The fan on the replacement PSU did nothing at all.

I had both plugs in as well.

Time for a new board, and I have a new power supply I probably didn't need.

Thanks.
 
this happened to my vnf3-250 last week, i think it was a short on the case as I reseated some components and it started up. I'm done with chaintech boards from now on tho, and I don't think i'm going to be putting my next mobo in the case either, i don't mind building systems but im sick of worrying about stuff like that.
