Solved Graphics card burning (replaced) last night sub woofer done the same.

[Tekken179]

A few days ago I replaced my PC monitor as my old one was, well old and starting to go.

Plugged my new monitor in and everything seemed fine, I smelt burning and quickly pulled my desktop only to see a tiny flame on my graphics card. It was removed quickly , but it had blew (burning plastic smell).

Last night my sub woofer seems to have suffered the same fate, I smelt the same burning smell and quickly turned everything off and removed the sub.

I have no idea what is causing this the sub was working fine all day and nothing in my desktop was over heating or looks loose.

The sub was connected via main socket and was roughly 5-6 years old.

My graphics card was two years refurbished so god knows how old..

Could it be my PSU? It's 405w and never had a problem with it.

No idea how to check to see if its being pushed beyond its limits but I can't see how it has been of its been working great (it's my only thought to what's causing this)

The other being pure coincidence and it was just there time to go. Although I've never had anything burn like this before if it was starting to go.

I can take detailed pics of inside my desktop if needs be.

My other problem with my new graphics card is in the graphics card section

well you can rule out your psu as that doesnt power your subwoofer. it should have its own power source. unless youve done a bit of a bodge to get it to run off its psu!

however a 400w psu for a 6670 isnt really man enough. im not 100% but I think the recommended psu is 500w

 

[badger906]

edit.. I stand corrected it is 400w, but you want to exceed the minimum by a fair margin as things such as dvd drive, additional hard drives, things plugged into usb ect all eat wattage, and you have 5w spare! also if its a cheap generic psu the chances are its not going to be a stable 400w

 

[Tekken179]

No PSU hasn't been tampered with, sub was connected via mains, the socket extension lead is a cheap 1 pound one could that be the problem? It had the monitor , desktop, speakers, 3ds charger, Ethernet box all plugged into it. It says maximum wattage is 3000 so I'm not sure, as far as upgrading PSU it's something I've never done and wouldn't know where to begin I've had it and the same peripherals for two years why would it only start surging now?

My PC at this point is and will be staying off, afraid of anything more going wrong and can't afford a new one.

If you can stretch to it I'd recommend getting a Corsair CS550M PSU and a Surge Protector.

 

[Tekken179]

Can get the surge protector locally, a friend has a 550w PSU that he's never used he's unsure of the make but going to look into it today. Thanks guys once I'm off my phone I will give rep.

If you can please check out my graphics card thread appreciate it guys.

Make sure any PSU you fit is a branded one, I always recommend Corsair. No matter the rating a cheap PSU can cause you problems. It's the engine of your machine and many people often overlook it or at least consider it unimportant. I'll take a look at your GPU thread, is it the same card that set on fire?

 

[Tekken179]

Same card but its a new one, software problems, installed fine and PC picked it up full list of my adventure with it on the thread, its some read.. Haha try I'll find out brand and let you know .

 

[Tekken179]

The PSU my friend has was a cheap EZCool.. Will this one you recommended work with my PC?

 

[badger906]

chances are the issue was caused by your psu. its so close to the recommended requirements of the card it was probably pulling at almost 100% the entire time.
that and it being a prebuilt computer means the psu was probably a cheap chinese jobby. (you can normally tell as theyre just a generic metal grey colour).

almost all pcs take an atx powersupply. its only in extremely small pcs and or flat cased types (where the monitor sits on top) but the fact you have a gpu means its not the case.

changing a psu isnt as hard aa youd think. a quick search on YouTube will throw up dozens of how to vids

 

[Tekken179]

Can't afford it this week but will have to get one next week and the surge protect extension lead asap, until then PC is staying off unfortunately. Unless I just unplugged the GPU for now but I couldn't handle that lmao.

 

[Boozad]

The Corsair one? It will indeed.

Hi there

Graphics cards can run extremely got -- make sure adequately ventilated and Heat sinked. Some might also have extra fans as well -- ensure these are working when computer is switched on -- note also MODERN PSU's have slightly different arrangements to the older ones -- your MOBO might not be 100% compatible with a newer PSU - or at least ensure all the correct fans etc are connected and running properly.

Bit surprised about the SubWoofer though -- how in the world can those BURN out !!! the ony way I could see is if they are fed directly from the mains / PSU and the voltage is incorrect. Simply overloading the sound output shouldn't burn them out -- might have hideous distortion (although on a sub woofer unlikely) or the vibration will damage the speaker possibly permanently.

Cheers

That's great, tbh although this has done some costing I'm glad it didn't fry the processor or motherboard. Will order it payday Tuesday along with extension lead.. And speakers... Lol Hope to god it just has been the PSU all this time.

Found it weird to still don't understand it the sub was always down low as its all I needed.

Is it possible for a PSU to send surges to an extension lead and the hit the first thing it could through the mains in this case the sub?

 

[badger906]

you are lucky I once had a gpu blow while stress testing, took out all my ram and cpu with it!
back when 1gb ram was £100 and I had 4 dimms!!

buuut ebuyer were amazing and replaced it all!! even upgraded my 8880gts to a gtx as they had none in stock

 

[Tekken179]

Hey guys mid £60 seems to be my limit I see the 550w corsair you shown me is around that mark but so is the 650w should I go for the 650w?

 

[badger906]

650w would give you a little more future proofing, and head room for upgrades. I run the corsair hx650w modular psu and its faultless in my eyes!

 

[Tekken179]

PSU on its way and the anti surge extension, wouldn't know much about the extension I understand the concept but now how it works,will give it a Google. Any recommendations for 3:1 speakers? Also did anyone get a chance to look at my thread about my graphics display driver and CCC?
