i had a friend bring over a pc he wanted to me to fixup and upgrade

within a couple seconds of plugging it in (before i even hit the power button) i hear some very loud crackling and then flames pour of of the slots in the powersupply (i had the side of the case off so i got a nice view of this, it about burned off my nose hairs :) )

i very quickly unplugged it and luckly the flames went right out... but boy did it stink!!


i called him to tell him the bad news and he didnt seem suprised, he neglected to tell me that he suspected something like that was happening.... the freaking idiot pluged it in a few days earlier and heard the loud crackling/shorting sounds so unplugged it. then the next day he did the same thing. and so he brings it over and the moron doesnt bother to let me know (first it scared me to death, then im feeling guilty like i killed his pc)



the odd thing is the motherboard seems 100% ok, and so does the ram, cpu, and all the adding cards like lan, video, modem... but every one of the drives is shot (the floppy, cdrom, cdrw, hdd)




but the reason for my post was to ask a couple questions
1. how could the sensitive stuff like the mobo survive??? and the drives (not one drive, but every drive) get killed?
2. what could go wrong in a powersupply and cause this?

i would take a pic, but really nothing to see.... it was on the floor, laying on its side (with the side panel off) when i leaned over it and plugged the powercord into the powersupply. my face was only about 12" from the powersupply. then it happened so quick and once i unplugged it the flames disapeared leaving very little trace.


i did pull off the cover of the powersupply expecting to see a big mess, but all i could really see was black burns on the board

Sometimes it's just too much dust in there if the psu is old & it can burst into flames.

sometimes its just old,sometimes it just blows up for no reason.

yup budman it was really dusty

can the dust cause a short? or can it cause it to over heat and melt something that causes a short?

a little of both,the dust can cause a short then the dust itself is flammable so it goes POOF!! .


I try to open up my PSU every couple of months to give it a blow job.;)

After that my PSU is very happy. :Q:D

Sprinkle some dust on your buddy and.......no, better not. Your wife would probably think that was funny. Jeez! What am I doing posting in this thread? I just realised it's full of old farts! :)

My friend got his PSU on fire aswell. But he didn't bother to check from his newPSU what the voltage was set at!
So it was set (at factory) to 115 insteadt of 230... and yes, it made a loud crackling sound and then bursted in flames?

Did this PSU have a voltage switch?

About the drives, all components that are directly connected to the PSU are at highest risk of damage (= HDD, CD/DVD, FDD and ofcourse mobo). The mobo has numerous capacitors that in most cases prevent anything connected to mobo from frying.
