| 441644 | 2006-03-29 05:21:00 | ill make this as short as possible (thanks to any and all who can help me) i came home and i smelled electrical burning. my computer had shut itself off and my room was lightly covered in smoke. i quickly unplugged it and then checked around inside and looked over the processor and such. nothing looked damaged so i turned it on. It gave me a "CMOS/GPNV checksum bad" message and allowed me to hit f4 to enter setup. when i after browsing in setup for about 10 seconds my computer beeped loudly and shut off. i turned it back on and it shut off almost immediately. that message seems to be linked to the cmos battery needing to be replaced, but that wouldnt cause the smoke and such :help: any help would be much appreciated. |

| 441645 | 2006-03-29 05:40:00 | I'd suspect the power supply unit . It's got things which can smoke before they cause a shut down . ;) But usually when smoke has come out, things don't work again . It has escalated . . . from POST starting, then 10 secs or so to immediate shutdown . Do any of the components on the motherboard look funny (as if they had been hot) ? The notorious leaky capacitors would tend to be effectively open circuit after failure . The voltage regulation components on the MB should be able to shut themselves down, but thay can fail to short . Interesting . ;) |

| 441646 | 2006-03-29 05:43:00 | IF your computer IS the cause of the smoking, for the love of the Master Builder, LEAVE IT OFF! I would SEROIUSLY suggest taking it to somewhere like Tisco or a reputable computer store and explain to them what the problem is. Nothing is more important than ones life |

| 441648 | 2006-03-29 05:56:00 | haha . . . well i repeated the process (startup -> get to setup, shutdown, startup straight to shutdown) again (which makes me feel like it has something to do with heat) . all of my capacitors look good as new and everything on the mobo is nothing more than a tad dusty . it is not plugged in to any power source and will not be :thumbs: (smoking was definetly computer, unless it was my alarm clock; that was the only other electronic plugged in in my room) i was planning on a second build in a couple months . . . maybe it may come a bit sooner haha thanks for the help =D |

| 441649 | 2006-03-29 05:59:00 | After it has shut down, try touching the heatsinks on the voltage regulators. If they have shut down, they will be "quite" hot. But I'm still inclined to suspect the PSU. | Graham L (2) | ||
| 441650 | 2006-03-29 06:08:00 | after the first trial i ran my hand over the motherboard and i didnt feel anything particularly hot. ..i didnt specifically check the voltage regulators but i probably would have noticed if they were "quite" hot the psu doesnt seem to be overly hot at all or smell much at all like the intensity of the electric burning that my room has haha (the worst scent is from the air above the processor, near the fan on the top of my case) anyway i will try more tests and such tomorrow, long day and school tomorrow (high school sucks) thanks a ton for your help! |
