View Full Version : AARGH!! COMPUTER BLEW UP! Need advice......

Just returned from a relaxing holiday in Northern Ireland (dodging petrol bombs and the like!)....

switched on PC. Nothing. Funny Smell. Tried a different power cord. Funny Smell.

OK. Heres the deal I turned off my PC at the mains before I went away and turned it back on at the mains on my return. I have a surge protect mains adaptor.

With the power cable plugged in a small USB LED at the back of the case is lit, but there is no reaction from the PC. This worries me a bit.

I disconnected the PSU and unplugged it from the motherboard and all of the components. There was a definate electrical burning smell and also upon opening up the PSU case there was a bit of a component (maybe a capacitor or something) rattling around.

So the question is, how likely my motherboard or other components are fried?
Im thinking of simply buying a new PSU and trying it, is there any way to know if i have suffered component damage? or do i not know until i buy a new PSU and plug it in?

do PSU's have some sort of surge protect or other protection for the motherboard? the component was over 2 1/2 years old.

any advice for buying a new PSU? I dont want to waste loads of cash only to find the computer is gubbed...


at the moment im sitting in work praying my bloody PC is ok.....

You could buy a PSU tester, here's one for an example;

The chances are that it is your power supply that is faulty and that once a new power supply is fitted it will work fine. Try and fit one that has the most wattage for your price range A good power supply is essential i reckon you should be paying around 45-50 (remember you get what you pay for) that way it wont be straining if you up grade Graphics and sound etc.

Thanks Helgstrand, im pretty sure it is the PSU though- there was definately a bit of electrical component rattling around inside the PSU.

Is there any way to know if the motherboard and/or components are fried?

Short of plugging in a PSU that you know is working and powering the whole show up, not really. You might be able to borrow one from a friend who's a computer geek and has parts lying all around the house, just for testing...

It may not be "okay."

My power supply blew up in a shower of sparks, and it rattled, little burnt pieces inside. Just throw away and get a new one. But, as the case was open at the time, seeing the explosion myself helped me diagnose the problem. http://forums.ubi.com/groupee_common/emoticons/icon_smile.gif The explosion sent current that fried my hard drive, motherboard, CD, and floppy drive. If you put in new power supply, it may or may not work if the old power supply blew something else like the motherboard.

My explosion was a good thing for me, because I decided to get a motherboard with AGP slot (and so finally become a *real* computer gamer), since I was using a board with no AGP slot andhttp://forums.ubi.com/images/smilies/34.gifTrident integrated motherboard video, so I had never really PLAYED the FB but just learned the sorcery of Full Mission Builder. With new AGP board and ATI9200, I started playing the FB. http://forums.ubi.com/images/smilies/11.gif

This is torture, im stuck in work with my new 400 PSU wondering if my 'puter is in fact dead.

http://forums.ubi.com/groupee_common/emoticons/icon_frown.gif

thing is i never actually powered the computer up, merely turned it on at the mains. Surely theres some sort of internal fuse to prevent component damage + i have a surge protect plug?

also with the ATX supply connected to the mains I would get keyboard lights and led's just no main power.

i opened the ATX PSU up and reckon i can see a fried fuse.

this is all speculation.

i might cry

go for a good make of PSU, like enermax, theres cheap high wattage PSU's about but avoid them.


where do u live? someone might have a spare pSu they can send u, sadly ive only got a cheap 300watt that might be dieing...

even the hardware is bust, the new psu can be part of your new homebulit system, saving u money http://forums.ubi.com/images/smilies/16x16_smiley-happy.gif

I saw many PSUs with burned fuses, many in almost same conditions (like no surge supressor), after I changed the PSU everything went back online.

Last one (one week ago) made me some trouble though... the owner leaved home for one week, I supose some storms hit his neighborhood and some elecric charges came into his Lan card too. After I changed the PSU I switched on the unit and all started till the beep that never came. So I pulled out peripheals till I find out that the Lan card was so fried up (with no phisical signs) that prevented the BIOS to start the PC.

So... if you had a lan cable conected to the unit and (agravating) you have an onboard lan adapter (that is on the mainboard)... well... finger crossed and hope for the best. http://forums.ubi.com/groupee_common/emoticons/icon_smile.gif

My computer was off when my power supply blew up, but it was one of those cheap things, so a better psu may have protected your other components. Let us know what happens when you plug the new one in, -- if it does not start and if you have another close way of getting on the internet, say another computer or a room mate's computer or neighbor if yours does not work.

I am newbie at computer components, but I hope that your hard drive isn't affected (that HD is still working properly) because I reckon that may be the biggest loss of all. I know that would be a biggest loss for me.

Thanks for replies guys http://forums.ubi.com/groupee_common/emoticons/icon_smile.gif

@Lexx: Thankfully ive got internet at work, so i will definately let u guys know how i get on tonight. If anyone lives in Glasgow they might hear a inhuman scream.

@Kuna: Yeah, thats why im worried. I didnt realise that the HD could suffer, but apparently the whole caboodle could fry. indeed also the backup HD i purchased!!!!

ive got Home and Contents Insurance with accident cover but i reckon they only give u what the PC is worth now.....

also a small confession.

NOT CONTENT WITH A FUNNY SMELL AND NO COMPUTER I DECIDED TO REPEATEDLY STICK THE POWER CABLE IN AS IF I COULD SOMEHOW DEFIBRILATE THE PC ALIVE WITH THE SOUND OF ELECTRICAL SHORTING.

now , with hindsight i realise this may have been remiss of me....

when my power supply fried, it took hd with it, everything else was ok though.

so backing up is a good idea.

Thing is I bought a PSU for 35 quid at Maplin electronics, but ive been hearing all sorts of horror stories about the manufacturer

its a Q tec 400w GOLD dual fan PSU, which apparently is the pits of the earth re. PSU's

also i think it was over priced.

i might actually take it back and then see if i can get a more reputable brand, now i know the rest of the PC is fine.

anyone got any experience here?
