My main COW burn up in smoke today...

My dual slot 1 P3 700 MHz literally smoked this morning. There are two ring like parts wrapped with a few turns of copper wire that burned. The capacitors next to it seem expanded. I had it on overnight. When I woke up this morning, the computer fans are working but there's no image nor light. So I turn off the computer waited a minute then turn it back on. It was booting when I started to smell and see smoke coming from the computer so I turn it off.

This is the second Epox KP6-BS motherboard that smoked. The first one burned the MOSFET voltage regulator of CPU1. The same capacitor is expanded as well. Has anyone have similar experience with Epox motherboard?

Now I need to look for another dual slot 1 motherboard. I should have ordered 2 Tyan boards from overstock instead of 1.
 
and i thought you were having a bbq.

i really hate it when you can smell the burning.

i have had that happen to a few monitors over the years
along with mb's and some other stuff.

the best is when a ps cooks.

one blew on one of the servers many years ago.
the fan was running and if you looked at the
back of the case there was a steady stream of smoke
coming out.
 
A moment of silence for a dead cow 🙁



I certainly hope you get it back up soon! and that nothing but the mobo is fried!

the coily things are called inductors. you seem to have had a voltage spike, is your box in a surge protector or a UPS?
 
Both were on UPS. Different computer/power supply-different location-office & home. At the office, I replaced the board with Abit BP6 and it's been running since then - that's about 8 months ago.

This one is at home. Power supply is a 300 watts. About 4 months ago the original 250 watts power supply overheated because the fan stopped working. I got the replacement from CompUSA.

Both boards from the beginning has a lot of fluctuation on the Vcore voltages. I even had to remove the motherboard monitor from Epox because it keeps giving me a voltage fluctuation warnings.

I'm considering replacing the board with a VIA based motherboard. Does anyone have any experienced with Tyan 1834DL? I've heard that most overclockers prefer Tyan 1832DL than the 1834DL.
 
Isos,

Dang shame about that board as it's a lot of keyrate to lose for a while. 🙁 I'm running an Epox Super7 board that I've had nothing but praise for, but I don't have any experience with any of their Slot1 stuff. Cost aside, I've got my fingers crossed that you'll have it back up and going with a minumum of headache.

I see networkman is one of the few people people in the world that knows the dirty little secret about ALL microelectronics!! Ya'all thought they worked on circuit tracings etched in silicon and boy were you wrong! 😉 The truth is.... they all work on a small internal supply of SMOKE!

What's this? You say you don't believe me? Okay... to prove it, just pick any microprocessor or other component and let the smoke out of it and then you tell me whether it works or not! 😉

I proved this theory on the first day I bought a brand spankin' new 486 and motherboard. Does anyone else here remember that with the 386's, you could put the processor in the socket reversed and while the computer would not boot, it would also do no damage to the CPU? Well, much to my disgust, I learned that was NOT the case with 486's. :Q About the time a small circle on the processor had progressed beyond cherry RED and was moving into the ORANGE span of the visible spectrum, I figured out that something was wrong! 😉 It not only "let the smoke out" of the CPU, it even melted the socket! Back in those days, that added up to about a $450 mistake for a lousy 33Mhz processor. 😱

IsOs,
Sorry to hear of the loss of your cow. 🙁 Here't to hoping you get a replacement MB soon! 🙂

Networkman,
ROTFL! 😀

Thunder,
ROTFLMHO! 😀 and Ouch! ($450 for 33mhz) 🙁

One of the guys I worked with let the pre-installed smoke out of a monitor once trying a new fangled software app that was supposed to give 132 col. display on an 80 col. monitor (for mainframe screen displays). Hooked it up, loaded the software, and *poof* there went the installed smoke! :Q
Afterwards they found in wee small print in the back of the software manual a warning about incorrect settings causing damage (read letting the pre-installed smoke out 😉)

And recently my son let the smoke out of a K5133, and he hasn't been able to get it to work since. :Q
 
Thanks for all the kind words!

Thunder,

Yes, I had a 25MHz 486 that got electricuted when it was inserted in reversed by my former friend. I can't seem to recall if any survived the tragedy! I know for sure something died. I guess the trauma had blocked that part of my memory - could be just a bad memory block!

I haven't found any good deal like the one I got from overstock.com (I can't thank Russ enough for the great service he provided! You're the man!) So this weekend, I'll dismantle the dual Celeron running at 464 so I can use the OEM Tyan board with the dual 700MHz.

I'm considering the newer Tyan 1834DL but I've noticed that overclockers prefer the Tyan 1832DL, revision F. Why?

Who sells the new Abit VP6? Any comparative review between Abit VP6 and MSI 694D?
