Question about power supply explosion (updated)

A friend and I were attempting to install a Dvd drive to replace a busted CD rom drive. After it was installed we put the case back together and were ready to setup and turn on the computer to test it out. Shortly after reconnecting the power cord, and before we finshed connecting everything, the power supply blew up. I still don't know why, I can only guess that it was just due.

Unfortuanatly after installing a new power supply we found that the MB was fried. Now I would like to know if anyone has any experiance with this, that would also be willing to comment on the probability that the processor is fried as well. I would hate to buy a new MB only to find the processor is fried.

It was a Soyo K7VIA with a 1 gigahertz Athlon processor.

only way to find out is to test it on other people's computers...

test another's cpu on ur mobo...then test ur cpu on another mobo..

it's the only way...
 
The motherboard wouldn't power up at all, on a new power supply. So I had assumed that it was fried. Is there some possibility that the processor was fried and motherboard is fine?
 
again, u can never knw...even though the led on the motherboard won't light up, u never knw until u test it on another person's computer....and yes there is some possibility.... that the cpu just fried, and hopefully that's the case, but regardless...i wish u the best....hope everything works out dude...really sux ur in that situation....
 
Ah, it's not really all that sucky. The owner saw it as the perfect opportunity to go buy another top of the line machine. I used a MB/cpu combo that was collecting dust since his wife got a laptop, to fix the exploded one. His daughter got that computer. I've pretty much inherited the remaining parts.

My only dilemma is whether its worth the risk of trying to get this thing working since I don't know anyone that has a a system I can test the parts on. I'd have to buy the parts, and that's not going to be economical unless it's the MB that is bad.

I've been thinking that if the motherboard is OK, then it should power up if I remove the processor and just plug in the fan. Well anyway I'm mostly just tortured by the thought that I could come up with a nice upgrade by buying a $40 MB. Maybe I should just throw them away and put it behind me before I lose money.
 
I think your idea of powering it up without the CPU is a good plan....I mean if nothing but the PC and power switch are attached then it can't really damage anything else!!

Whatever you do, DO NOT test a good cpu on that motherboard. Usually when the motherboard gets fried like that it takes the cpu with it. Your cpu and motherboard are both probably dead. Some friends of mine have had problems like that too, and 3 seperate incidents i know of when the motherboard fried they put a good cpu on it to test it and it destroyed the good cpu.
 
Thanks, radioactiveballpoint.

I hadn't planned on it, but that doesn't mean I won't do it in the future, so I'll have to remember that.

So I take your opinion is that they are both dead?
 
Update:


Today I had time to do something more than just talk about this. So I took the MB and hooked it up to a powersupply, and plugged in the CPU fan. At this point, the power supply is making a faint whining noise. But otherwise it's fine. So I go ahead hit the power pin with a screwdriver. And everything fires up normally. With the exception that the cpu fan needs replacing, it makes a lot of noise.

So I think HUMM, and plug in the CPU. At first it won't power up, but after some fiddling with it, the motherboard fires right up. So I hooked up a harddrive, a video card, a momentary switch and some ram. It does power up, post and behaves normally, but usually only for a few seconds before shutting off again. You usually hafta hold the power switch down for four seconds, after each attempt to power it on. But eventually it'll start up and run normally for a few seconds. It's resistant to powering up, even when the processor is removed, and the power supply continues to whine even with the power off, and the cpu out.

Now I think that the motherboards power circuits are bad, and this is why the original power supply failed. This is conistent with the strain being put on the power supply. I'm assuming the processor is fine since it posts. So I think I may just pick up another MB for the cpu.

Anybody, Got any better explanations, thoughts, or opinions?
