Oh dear...

This has just happend, I should've known better than to tinker!

Built myself a cheap but effective pc a few weeks back and decided after a few weeks of running in to stretch it's legs.

I built, based around Antec Sonata II case, an Asrock K8NF4G-SATA2 mobo with an X1800XT 512mb and 2gb Corsair xms3200 ram. I used my existing clawhammer 3200 754 cpu (as I hate throwing stuff out :rolleyes: ) and after hearing the results people have been having with this cheap wonder I decided to give o/cing a go.

Well I managed to to get some good results, but getting late I decided to return it back to stock and knock it on the head for the night, this is where it went rather hazy, literally..

I saved changes in BIOS and waited for it to POST, screen went black and nothing happend, all of a sudden I couldn't see anything the room full of smoke *panic* rip case out of desk/yank out any cables/kick open patio doors/dump case in garden/open windows and doors before I die of smoke inhalation, jeeeez h corbett I've not moved that fast since, well a long time!

Just brought the case back in doors after wafting cushions around the conservatory getting rid or the putrid electrical burning smell/smoke, opened it up and what had caught fire....??

I'll save that for the morning, keep you lot guessing.

:D
 
Ignore me, I looked up the mobo and now I know that you can use PCI-E and 754.

Hopefully it's the PSU and it hasn't taken anything with it!

Maybe today isn't the best day for you to be posting ;)

I reckon PSU. I can't think of anything else that would fill a room full of smoke... unless you left your turkey in the oven too long!

Well it's not as exciting as any of your guesses, thank god.

It was the pesky speaker cable??!

It's amazing to think this little cable going up created so much smoke, the pc is back up and running now (without speaker cable plugged in..) and running at stock :D

I checked the route and there is no sharp edges it was up against and it's been plugged in the same way for 3 weeks! I didn't know overclocking effects pc speakers?!
 
Wah!

That shouldnt have any sort of voltage/amperage passing through it that could cause that sort of damage!

Do you have a multimeter? Can you check what the outputs on the speaker connections are on the motherboard....

I really can't see what could cause that. At least everything still works after you "dumped" it in the garden. Good job it was'nt mine. I would have had to chuck it out the window. Pc room is upstairs in a cupboard.

As for pci-e and Sli on 754 see my siggy. :D :D
 
Honestly, you'll come up with anything to get out of doing some work these days unK's :p

Did you tell the other half? Prob see smoke coming out of somewhere else if you did lol ;)
 
That cable sleeving STINKS when it overheats.

You'll probs find that the positive wire (the red one) always has current going to it, it's the negative wire that is switched (the black one) and the positive circuit has earthed out on something (maybe the speaker has shorted itself out during the POST beep, all it takes is the internal coil to snap and ark against the speaker chassis, earthing right through that, then onto the case, up to the PSU and down the earth cable) the unrestricted current overheats the copper wire and the shielding goes up in smoke. Ergo lots of smoke and a nasty smell.

Sherlock Bundles does it again :p

"Great Scott Bundles! You're a genius!!"


Seriously, nice bit of fault diagnosis there, when I dig up my multimeter later i'll find out for sure what's gone wrong.
