Burning Smell, Black Screen & PC Freezing

Q: Burning Smell, Black Screen & PC Freezing

My PC: ASUS P4 2.67G with 1G RAM. nVidia FX5200 AGP graphics card. Compro TV Tuner Card. XP Pro SP2.

Background:

Last Wednesday i installed a new TV Tuner Card. System was fine til about 3 days ago.

The problem:

The other day i was working on my PC and started smelling a mild electrical burning smell. The smell faded before i could figure out what it is, but came back again about 10 minutes later, followed closely by my system freezing and my monitor going black. I had to pull the power cord out the back of the system to turn it off.

After a few minutes i turned it back on again, and it appeared to boot fine. About 5 minutes after using it, the same thing happened again and the screen went black.

At this point, i figured the problem was most probably my AGP Card, so i got the case apart and took it out. After changing my monitor back to the on-board graphics (SiS chipset) the system appeared to boot fine again.

I used it for probably 10hrs of use after this and was thinking the problem was solved until this morning when i smelt that burning smell again, followed by the entire system freezing up. This time though, the screen did NOT go black, so i assume the onboard graphics are ok still.

At this point today i removed the TV Tuner card, rebooted and it loaded fine. I've not used it much this this happened.

I'm not sure what actually caused these problems, or if they are more serious than they appear.

Notes:

I have looked at the AGP card & the TV Tuner card for marks or signs of burns, and neither have them.

The problems all started days after i installed the TV Tuner Card (in PCI Slot 3).

Is it possible that the TV Card was the catalyst of the problems, and has actually caused damage to the AGP Card? Does anybody have any insight into this type of problem?

Hi,

I have been having a few problems lately and now I have these tiny blue dots on my screen. They go in vertical line and are not always there. I have also now noticed a burning smell from time to time and I thought it was the power cord so I bought a new one and now I know it's coming from the system.

Any information would be appreciate as to what I may do to find out exactly what is happening with my PC. I read a few things online and it says video-card but how can I tell for sure?

Any help would be great!

Thanks.

I have an HP Media Center m7480. I use it for my music, TV, and Movie entertainment. It has been great until about a week ago. There is now a electrical "hot" smell coming from the unit located at the top rear of the machine (main power cord plugs into it as well). The system still works, it just smells hot now. I dusted and cleared some potential ventilation issues, but I am sure the damage is already done and just need to replace what is burned.

I am a beginning Computer guy and would like to fix it myself. Do I need to replace that entire upper unit or can I find the exact piece that may be getting hot and replace it.

Also, what may be the best options to keep them from heating up so much in the future (other than better cleaning and dusting practices).

If it is continuous then you need to replace power supply.

Well I was installing 4 more case fans ( not attached to my fan controller) next to my video card because I was overclocking it some. After I got done I plugged everything back in and booted my computer up. All my case fans started spinning fine then all of the sudden my cathode lights flicker and I immidiately unplugged the power from the tower. I then smelled a faint burning smell and a crackling noise, kind of like a monitor when you plug it in. Will overloading a power supply fry everything or will it just not work? WHen I was picking my computer up and putting it back on my desk I think i bent one of the cathode lights (would that short it out, then in turn short out my fan controller?).

Please note that I know for a fact that it was not my video card that caused the problem.

Burning Smell

I am running a HP a600n, Win XP Home, 512 MB Ram, AMD 2700.

Today I started to smell something that resembles buring plastic. I could smell it coming out of the back of my PC and the power cord was somewhat hot to the touch. Not too hot to touch just hotter than I thought it should be. Anyway I opened up my PC and my video card is pretty hot. It is an old card, nvida 64mb, that I have been running for about a year, after being retired for several years. Are video cards usually hot to the touch? I thought it might be my power supply but that does have an overbearing smell and it is not hot to the touch. Does anyone have any suggestions for me? Am I hurting my PC by running it and is my video card the possible culprit? Thanks in advance for your help.

For about a year and a half I have been running a Radeon 5870 on my machine, but about a month ago I switched it out for a GTX 580. The very first time the new card was under load, I began to smell what I thought at the time was 'burnt dust,' as the GTX runs pretty hot under load. The smell was a bit annoying, and even abrasive enough to give me a scratchy throat during a prolonged gaming session (thought it was in my head). Fast forward about a month, and the smell has only gotten worse. I've since cleaned out my case, but that didn't help. The GPU does run hot, and the smell seemed to be originating from it, so I put my Radeon back in to check and see if that would solve the problem. It didn't; the smell persisted. Sniffing around my machine, the smell seems to be coming from my PSU, which made sense as the GTX requires a bit more power than the Radeon, but I was under the impression that if a PSU was burning out or failing, my PC wouldn't run, and it was running just fine.

Basically I want to know if I should replace the PSU. It's an 800 Watt ATX PSU by Cyberpower (I didn't think they made their own components). Could that be the source of the smell, or should I try something else first? At +12V, it says it runs 50A, which should be enough to run the GTX just fine. Any suggestions?

Hi Guys am starting to smell somthing like burning rubber not realy sure if its rubber when i on the pc there is no smell what so ever but when i run MW3 at full Graphics the smell starts so what is this smell ? is it the video card ?

A:Burning Smell

The chances are that one of the fans is burning up at high RPM. It could be the video card, heatsink, case, or even the power supply fan in that order. Isn't the smell more of an electricity related smell?

Sorry if this is a long story

I have lived in this house for 5 years. In that 5 years I have bought and returned under warranty at least 30 desktops and laptops. Probably more than 30 but I don?t want you to think I?m exaggerating.

What all these machines had in common was fried components. Either PSUs would fail and need replacing. Quite often high end GPUs would show visible burn damage. Even motherboards have fried. The first sign I get is the PC or laptop will shut down. Then when try to switch on it will often just briefly try to start (ie fan spins briefly or keyboard lights flicker) but it will fail to POST.

The last desktop I bought was a Dell Alienware. I made sure I paid extra for a tech to come to my house to fix it. He visited 3 times replaced the PSU motherboard. I even had Dell send me a complete new machine. After 3 weeks of it working I had to call out the tech again. He replaced the PSU again and as he plugged it in to the wall socket and switched the machine on BOOOM with clouds of electrical smoke! He couldn?t believe it!!

There seems to be no pattern of when these machines fail. Sometimes I get a few weeks of working perfectly then it dies, sometimes with smell of electric burning sometimes not.

Other times a machine might last less then a few days. The previous four laptops bought in March this year ( 2 MSI laptops and 2 HP laptops) only lasted two days. I smell burnt components. All returned and refunded under warranty thankfully.

So I have a compaq presario f700 laptop. I always use the laptop on a hard desk surface, without clothes or stuff like that in the way. Starting about 1-1.5 years ago, it sometimes heated so much that it would shut off in the middle of operating. It still does that now. I then made sure to stack some books on the table and place the laptop on it, or place in on my lap, to increase the heat transfer by convection. Sometimes, it STILL would shut off, if I leave it on for a few hours and run lots of programs

Anyways, I began noticing more recently (can't remember when, could be a few months or a year ago?) that it would sometimes give off a burning smell if I run a lot of programs. I was too lazy to do anything about it since other than it running slowly, there weren't any serious problems. But now, I've finally decided I may want to take some action

I dont know where the heating and burning smell come from. When the laptop gets hot, its like that everywhere when I touch the bottom

I tried disassembling the laptop and didn't notice any parts that seemed burnt, but I've only removed the cover on the bottom. I can see one of the fans, and it appears really dusty. I would have to continue disassembling to see all the other parts. But to continue working, I need to get remove the 2mm hex studs on one of the parts.

A:burning laptop smell

hi there

it sounds to me that the main cooling fan has become inefficient, usually due to build up of dust and hair etc, stopping it revolving to cool well enough or even stopping it completely

i would say that you need to at least get the fan out and clean it, then reassemble and ensure its kicking in as it should by listening for activity from it or leaving the cover off, booting up the machine and watching for the fan movement

however if you have any doubts about doing this yourself, i'd definitely get it looked at professionally, a reputable repair company should easily be able to find the issue and responsibly sort it, overheating is one of the most common laptop hardware faults and as such is likely to be their bread and butter :-)

My HP Pavilion Slimline s5000, less than 2 years old, practically caught fire this morning.  I turned it on, started it up, and within minutes smoke came out the back and this horrible burning smell filled the air.  I turned the PC off, and now it won't turn back on.  The green light does go on in the back when I connect it to the power supply, but it does not start at all.  I opened up the side of the tower, and something in there definitely "fried", although I can't see exactly what it is.  It reeks of melted plastic and ash inside. Tower was kept on top of a table, completely out in the open.  So ventilation was more than adequate.  And, as late as last night, I still heard the fans going.  So, those were fine, as far as I know.  Motherboard looks OK too.  This is the first time I have ever had to replace a PC in such a short time frame. And, I bought an HP assuming it was a "quality" product.  Boy, was I wrong  The darn thing didn't even last TWO YEARS! What a piece of junk! Of course, HP support tells me it will probably cost a few hundred dollars to send it to them to fix.  And Geek Squad wants $149 just to look at it and diagnose the problem (plus whatever parts and additional labor it takes to fix it).  Something in there will need to be replaced, for sure.  So, I may as well go buy a new tower.  Which,  of course, will NOT be an HP.  And let's not even g...

It's hard to see without me seeing it personally. If it's working OK now I'd continue to use it as normal. However obviously they're not designed to work with backwards memory hehe.

I'd do a backup of your data just in case, and then keep an eye on things and see how it goes. I doubt the machine will catch on fire. Check the motherboard for any signs of blown capacitors or scorch marks maybe?

Can't remember the last time I dealt with improperly installed memory and then tried to boot so sorry I can't offer up more suggestions.

A lot of things could have happened. Reseat all cards, cables. Hard drives are subject to shock and given enough jolt can damage it permanently. See if there is anything rattling. Read the no p.o.s.t. guide in he guides forum.

PCs are delicate. A big enough drop can seriously damage components.

Hi everyone,

Appreciate any initial insights on this.

Was online using a VOIP program as well as playing an online game. Smelled a burning smell, and then the computer just shut down. About a week before that, for the very first time, my computer took a while to restart, just hanging on the windows logo screen. I had to shut it down and reboot and everything was fine. No updates were being installed at the time. Not sure if it was related, but it was the first time this machine had done that. This machine was built in late June of 2014.

So far: Tried a new PSU with it Corsair AX860 platinum. Tested the voltage on the CMOS battery (popped it out for a few minutes, tested it). Tested the old PSU (listed below) with the green wire test. No obvious damage on the mobo, but currently about to start taking my build apart and taking a closer look at everything.

Next, I heard an electrical "popping" sound. I immediately unplugged my computer. I play this video game all the time and for much longer periods than 45 minutes, so I found all of this VERY odd. This morning, I plugged everything back in and tried to turn it on, but absolutely nothing happens. It is totally dead...not even the fan or hard drive tries to start up.

Ok I had a virus on my pc a few days ago and through my negligence I waited too long to run a full system check and on restarting the pc it wouldnt go into windows just a black screen with the mouse cursor. Anyway no big deal most of my stuff is saved on an external. So I pluged my hdd as a slave into another computer to run a virus scan it took out a lot of files and when I pluged it back it it had the same problem so I figured what the hell time for a fresh install anyways.

Now today I was going to xfer my files that I had on there to my external and pluged the gimped drive into a recently purchased enclosure (NSP-E525) upon firing it up the HDD began to make a lot of noise as it began to spin. thought it was just it starting up but then I smelt a electric fire smell and quickly shut it off. Upon inspection It was coming from the HDD. Just recently I tested it on my other pc installing it internally it imediatly began making the same noise so I shut down again.

What just happened... and is there any recovering?!

Hey guys

So I was using my computer yesterday when it randomly shut off. When I tried to turn it back on, nothing was appearing on the monitor. I could hear the hard drive and fans spinning, but there was no display. After i tried to turn it back on, my room smelled strongly of something electronic burning and i quickly shut it off.

Earlier today I tried to turn it on again. The monitor was working this time, and it tried to start windows in safe mode. About 5 seconds into the Windows XP loading screen, i smelled something burning again and the computer shut itself off on its own.

Anyone have any idea what's going on and/or how to fix it? My best guess would be a bad power supply, but my knowledge of computer hardware is pretty slim, so some input from people who know what they're doing would be nice before i go out and start spending money. Any help would be greatly appreciated.
 

A:Comp not starting/burning smell

Hi,

First view would be Power Supply, then either the fan on your graphics card or the graphics card itself.

It could be the monitor though, to eiagnose this. Try the computer with a different monitor and monitor with a different computer.

I was on my desktop computer last night when it randomly shut down and I could smell burning but I was not sure where it was coming from.

I found that the graphics card was hot but this is not unusual, my PSU was hot but I don't usually check this and the heatsink felt fine apart from the CPU metal contact. I had recently replaced the heatsink as I broke the former when trying to clean it. I do could not see any visual signs of damage but I wasn't able to remove the PSU from the motherboard (but it has been there for 3+ years).

I could not tell where the burning was coming from.

My specifications are:

Intel Q9300
Nvidia Geforce GTX 280

ASUS P5Q (vanilla)

How do I best approach this?

A:My computer randomly shut down and I could smell burning

The recommended PSU for a Geforce GTX 280 is a 550 watt power supply so you've been stressing that unit way past its limit, so I would start by replacing the power supply with a high quality, higher wattage unit. We recommend the Corsair TX 650 quite a lot: http://www.newegg.com/Product/Product.aspx?Item=N82E16817139005

Okay I need some help. Two days ago I walked over to my computer and it had apparently shut itself down. I tried to turn it on again but got zero response. At this point my keyboard and other items connected to the tower. Showed power. I then hit the dedicated on off switch on the psu and there was no power to anything. Fast forward to today and out of boredom I hit the power switch and it turns on like there was never a problem except now there's a very bad burning smell coming out from it and I am unable to identify the source. It has a new motherboard in it about 2 months old and it doesn't seem to have any problems. I'm thinking that its perhaps a bad psu or potentially my graphics card burning up? The psu is an ultra 700 watt and the graphics card is an xfx geforce 9600 gso . They are both original and about 4 years old. Thanks for any help!

Okay well I changed out the power supply. Burning smell is gone. Starts up. Except my monitor is no longer getting signal.

Wonderful. Is it possible that the old psu burnt out my brand new motherboard? Is there something I did wrong that could cause this? I installed a corsair gs 800. Bigger then the old one... ugh please help

I have a month old laptop that has a burning smell when I boot it up. It works fine and the smell quickly goes away, but it is bothersome.

Hi sandione,
In order to find out exactly what is causing a problem, you can trying open the side cover to see which is that internal component which is causing this smell.
Refer http://dell.to/2mL8viy for user manual on how to remove the side cover. Please note if you are not comfortable removing any component, please take the system to local store.
Is the system heating up? Try cleaning the airvents, ensure there is enough air flow. If there is no hardware issue, this might help.

PC 1 Problem:
Hi, I recently built a new PC for a family member, but I have one problem the old motherboard fried due to a power surge, couple of days back I refitted a new motherboard but am having problems with the Case Power Switch I know where is goes on the motherboard but not which way, I know which is plus and minus on the motherboard but can identify which is which on the wire, at the back of the wire it has a small arrow on one side and nothing on the other. (Normally I have a sheet which identifies the plus and minus that come with the case.)

PC 2 Problem:
On another PC which I have built for someone else I could smell burning and I can't identify what is wrong I have built a few PC's but first time this has happened could it just be because its a new motherboard.

Thanks in Advance!

Case power switches, reset switches have no polarity needs. Plug them in anyway you want. Burning smells coming from computers is never a "normal" or good thing

Recently my PC was giving off a burning smell for maybe a week. Then the Power supply died. Replaced the power supply and all is working. But that soot smell is still in my Rig, primarily in my video card. Is this a bad sign? Or is it just a smell that will filter out over time? Just want to be sure.

I put in a little GT 610 graphics card about a week ago and everything has been fine since, I get up this morning and now there is the smell of burning dust coming from my computer.

I opened up the case, checked the fans, checked all the hardware, checked for burnt items on the motherboard and all seem to be in order, I checked what temps of things i could with the speccy program and all are in the normal range.

The computer is running fine, no slow downs or anything, can anyone suggest to me something else to look for, the smell of burning dust is quite strong though not overwhelming by any means.

Thanks
TC

A:smell of burning dust coming from computer

Hello TC,

Have you already gave the inside of your case a good cleaning and blowing out any dust?

How does the PSU look? Don't open the PSU because it can electrocute you even when unplugged. Only look through the grill.

Hey guys,Recently I woke up to a nightmare of a laptop issue. Laptops battery was dead and charger wasn't working. Once more, If I plugged in the charger, it would make this odd pulsing noise.Upon further investigation, I could smell something burning coming from the laptop. The adaptor isn't what's wrong from my belief as I ordered a new one and it made the same noise as the first. Does anyone have any ideas what might be wrong with it?Edit: The laptop is a year and half old.

It blown inside and maybe blowing the power supplies if it has not output either now.

I was browsing websites on a four year old Dell Dimension 4700 PC when all of a sudden the computer suddenly turned off. The computer would not turn back on and the power light on the front of the computer, which normally is green when the computer is on, blinked yellow over and over again. After unplugging the computer and plugging it back in, the blinking yellow light went away and the computer did power on (complete with green light), but there was a horrible burning smell coming from the machine and nothing loaded. Every time I try to turn on the computer now all I get is that green light and an incredibly loud fan, nothing comes on the screen, I hear no beeps, nothing.

What could this possibly be and what could I do to fix it? Thanks in advance.

A:Computer doesn't work after crash/burning smell

Firstly, don't attempt to turn it on anymore, as you're most likely cause more damage, each time, you do so.
Secondly, it's rather impossible to diagnose on line what's going on inside the case.
Your best option is to bring it to a pro shop.

Sounds like you may have fried the power supply. Remove the covers and see how much crap is covering all the components. A can of air blaster works good to clean out heatsinks and fans. Do any work with the power unplugged then carefully turn it on and see if you can see what is cooking in there.

Hello,

I just went out the house for a few hours so left my computer on standby. I came back to find the room had a slight burning smell which was confirmed by my brother. When I tried starting my computer it stopped at the screen as soon as the motherboard loads. Its never done that before. Nothing else electrical was on in the room.

After a few minutes it asked some question about whether I wanted to delete the boot info or continue with the previos boot. It was on about the standby information held on the hard drive however I cant remember how the question was praised.

Its been asking that question on and off the last few times Ive set the system in standby however its never left a burning smell in the room or anything like that. I just select to delete and continue and it loads like a fresh boot loosing any data from when it was put on standby.

I've been doing some forensic stuff imaging and analysing ram recently so god knows if its anything to do with that. It only started the past few days since I got into imaging ram however I doubt its relating as imaging ram shouldnt affect the computers ram state considering the importance it would hold in an investigation..

Has anyone got any idea whats going on? Suppose I better do some backing up.

Cheers.

Hello! I do hope you can help me with my spectre x360. It suddenly shut down while I was using it and it didn't start up ever since. I tried to hard reset it but eventually there was a burning smell located at the back cover of the unit and in the power socket.  What should I do with this issue? I would greatly appreciate any comments and suggestions. Thank you!
