I've heard of cracking your CPU core, but your....

Motherboard?

I 'had' a Abit KA7-100 motherboard (slotA, KX133 chipset, HPT370 RAID) that had always had a few issues. For one the USB would randomly cut out, and two the IDE conrollers would randomly 'loose' drives. Anyways other than these few glitches, which were easily fixed with either BIOS patches or new drivers, the motherboard worked fine.

Well I gave it to my parents about 3 months ago (they wanted a new system, their p200 was getting old & I was willing to sell them mine & buy me a new motherboard (check out my sig)). Anyways, after about 3 months they started complaining that it was acting up (randomly rebooting, locking up, refusing to boot). The symtoms they described sounded a lot like a dead PSU to me, but after changing the PSU, it still didn't work. Upon later investigation, I found several of the capacitors in the CPU PSU (the 3-phase power supply) on the motherboard had "exploded". The pretty silver tops had opened up and were dripping nice goo all over.

Anyone have any idea what would've caused this? The system was sitting in a closed box, so I know I can rule out any physical interferance.

power surge?

 

[CraigRT]

must have been... or somehow, somewhere, a defective part.....

that is way odd.... i hope someone can give you a more definite answer...

Power supply went bad and took out the motherboard.

Lick the ooze, if its a bit salty its the motherboard that blew up.

 

[sprockkets]

hehe, my friend in the Siemens factory blew up a power supply by setting the voltage wrong. Why I say this is because it must have happened while you were gone, cause it sounds like a gunshot when capacitors that big blow up, and you most likely would have heard it.

well I treid a new PSU anyways...so if it is the PSU that killed it we'll find out.

I am NOT licking it, I can send you a sample if you want a taste.

Dude!? You sold your m/b to your folks?

 

[Scootin159]

well kinda...I gave them my system, and they bought me a new system & then I paid the difference in cost (how much my system cost more than what theirs was worth).

Actually on my old Abit BE6 II i had a simliar experience. The machine was randomly restarting, i did some poking around and did notice that one of the capacitors had begun leaking. For me though i think it may have been a total cooling issue. I'm in hawaii (the machine had been used mostly in california with airconditioning) and when i rechecked the systemboard temp it was close to 50c (apparently during the move from cali one of my fans had died...

So the capacitor and motherboard cracking happens, rare, but it happens.

Lots of useful info here about motherboard capacitors

 

[Scootin159]

yeah, after talking to a few people the general consensus is that it was too hot.
