A: PC Case Power Switch & Burning smell

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

I just installed a new Antec SmartPower 2.0 SP-450 ATX12V 450W Power Supply in my computer 2 days ago. Now I am noticing a faint burning smell. I opened up the case while it is running and see no problem with the wires or connections. The smell specifically comes from the power supply fan on the back of the case. Is this normal or is the power supply faulty? I'm hoping its just some residue burning off and it will go away, don't really feel like replacing it again.....Anyone have any ideas?

A:Desktop PC - burning smell - won't power up now

Additionally, the little power button on the mobo is red lit when plugged into the PSU. No beeps when trying to turn it on. Fans don't run either. Speaker is installed on the mobo. When I do try and power up the machine after hooking up the PSU, I do hear a faint click, but nothing.

I just purchased a computer and am building it myself. Finished putting it all together yesterday, plugged it in, the LED on the Mobo turned on aswell as a blue LED on the case, however, when I go to turn the computer on...nothing. It won't even start a boot sequence, nothing. I know the mobo is getting power, and I know the pins are working as my blue LED is plugged in where the Power SW and the Reset SW plug in aswell. Need a little help, not sure if the Power SW is plugged in wrong or what, but I currently have it plugged in like so I:::I:::I from left to right starting with the HDD LED then the Power SW then the Reset SW. Any help would be appreciated, as I'm lost.

I smelt someting burning from the system case. While pc was on, the fan from the power supply was not turning. It is an antec power supply. The pc runs good, no sound or anything else. the power supply is new, so it's not dirty. Why is this?

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.

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.

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.

For about a year and a half I have been running a Radeon on my machine but about a month ago I switched it out for a GTX 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 Burning Odd Smell Please -Help a scratchy throat during a prolonged gaming Odd Burning Smell -Help Please 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 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 V it says it runs A which should be enough to run the GTX just fine Any suggestions nbsp

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?

The chances of you getting burned in MW3 is discounted

I recently put together a computer after buy all the parts. I noticed that there was a weird smell, like burning plastic. The case that I'm using is a Thermaltake v9 Black and the power supply is a Corsair TX750W. I tested each fan individually to see which fan was producing the smell with only the power supply, using a paper clip, and it seemed that all 4 fans are producing the smell. Is this just a burn-in period for the fan that is creating the smell? Or is it that the fan is starting to burn out, even though it's completely new, like fresh out the box new.

Updated memory on Diemension dell 1100. Put the sticks in wrong way. Turned on, no action
but a burning smell. Powered down and inserted chips correctly. PC ok now but would there have been any
permanent damage and is there a remote risk of the PC going on fire ?

A:Burning smell upgrading RAM

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.

So I burning smell laptop have a compaq presario f laptop I always use the laptop on burning laptop smell a hard desk surface without clothes or stuff like that in the way Starting about - 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 burning laptop smell a few hours and run lots of programs Anyways I began noticing more recently can't remember when could be a burning laptop smell 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 mm hex studs on one of the parts I checked a few nearby stores even Home Depot but none of them has it But a local computer repair store could remove it Is it worth it I don't feel comfortable with someone touching my laptop

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 :-)

The bottom is real hot to touch even though I give it room to cool.I've had other problems with it and was wondering if I could return it or do something about it. I've had the laptop less the one year.

two years ago I built a PC for my uncle, a Gigabyte mobo, OCZ ram, XFX 8600GT, Core2Duo and a 425watt HiPER PSU

after 18 months he reported burning smell coming from the PSU....

what could this have been do you think?

he replaced it with an unbranded type from PC world that cost about £40 after I told him to stay away from cheap ones... I got the HiPER as I was under the impression they were a 'half' decent brand and would have done for his system....

its just im worried if its something else causing it and will it happen again with new one? - although cheap it looked sturdy with a 12cm fan

Well if it still works it probaly just got hot without burning anything out. Now that they are in correctly there should not by any more risk of fire than otherwise. Some component may have weakened and not last as long now however.

I was playing a video game last night for only 45 minutes when my computer automatically rebooted on me. Next, I smelt a burning smell. It smelt like burning rubber. 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. Any suggestions as to what's wrong? I HOPE it's just the power supply in my computer and not something more expensive to fix...

A:Solved: I smelt a burning smell...

Sounds like a failed power supply. They aren't overly hard to swap out, but you need to make sure you get the correct type. And one with a bit more wattage.

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 dropped my pc the other day (a 2005 Dell Dimension 3000 stock), and then when I would start it, it would turn off 2 seconds to 10 minutes later. when rebooted it would say 'turned off due to themal error" then one time it did some scan thing and said drive was dirty and did a long start up scan... then later I turned it on and smelt burning from the psu. i took it out and inspected it and it looked ok, put it back in now it won't even turn on and a orange light flashes. Is the problem that i need a new psu?
should i buy one on ebay, they are only $20. also is a dimesion 2100 psu the same as a 3000? b/c one is for sale that comes with other items i need.
thanks for the help! I'm pretty newbie to computers sorry...

A:Dropped PC, won't start.. burning smell.. psu?

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.

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.

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.

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
Tagan 400W PSU
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:

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.

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.

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.

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.

I have a LaCie 500gb external harddrive that I use to back up my laptop and store large files. It has its own power supply and connects to my computer by USB. The other day I plugged it into the power supply and noticed it wouldnt turn on and there was an electrical burning smell coming from the plug on the harddrive. Is it possible that it is just the plug damaged and my data is still ok? Can I remove the data from the harddrive somehow? Would it be worth trying to get someone to repair it or should I just buy a new one?

I don't know alot about this sort of thing and any help is greatly appreciated!

Got a CyberPower CP1000AVRLCD Intelligent LCD Series UPS 1000VA 600W AVR Mini-Tower that seems to be working fine. But every now and then it gives off some kind of plastic smell. It had this smell when I first took it out of the box and the smell seems to emit every now and then while it's on.

I've touched it to see if it was hot, but it feels quite cool. So it doesn't seem to be overheating or anything.

I am connecting a new MB to my old case Switch & LEDs
the Blk & Wht wires go to the PWR-BT pins
the Grn & Blu wires go to the PWR LED and
the Yel & Brn wires go to the HDD LED
The original connections for the LEDs are not marked + or -
however the pins on the New MB are... the only indication on the old board is GRN /YEL (but not actually where these pins are) would that mean that the Grn & Yel leads are positive (+)? would anything drastic happen if I hook the LEDs up backwards? (so far I just have the power on/off connected)

It shouldn't hurt anything to hook the led's up backwards, they just won't lite up. So if they don't work you can reverse them.

There should be a wiring loom running from the front of the pc to the board, do a google on the motherboard and find out which connector is the power switch, it's usually next to the reset. speaker, HDD led and power led pins, once found short it out and if the mobo starts up its the case switch if not the mobo is dead.

Hi guys

got myself a silverstone ML02 case, Fatality F-i90HD mobo, quad core 6600 and 4 gig of ram. Problem is, it won't switch on!

I *think* i have connected it up correctly, the on-board red led lights up to tell me its got power, the front LCD screen lights up (everything showing). Problem is, when I actually try to turn it on, nothing happens. I tried also using the remote to turn it on with no luck. No fans spin up, no beeping, nothing....

The power cable appears to be an orange and white cable - which i've tried both ways round.

Any ideas?

A:Fatality f-i90hd won't switch on (Silverstone case)

By power cable I hope you just mean the small wires that go from the case to the MB. Are you sure it is on the right MB pins? They can be hard to read.

This is for an Antec case, where the inner, plastic coil on-off switch has come loose. The plastic pin retaining the flat, spiral coil on a side has broke (poor design, which is surprising for this make). The marginal mini pin snapped == case front is practically trashed. And if case front is no longer available, of course all components must be moved to fit inside another new separate case.

So looking for the best glue I can find to secure it back.

I hessitate to shoot glue, since every time the switch is depressed from the outside, finger pressure will be applied.

Anyway, what would be the best high strength glue for bonding plastic-on-plastic?
Is the glue gun better?

(notice that certain glues write out certain types of plastics under their recommended applications)

A:plastic pc case switch broke - looking for best glue

It is difficult to recommend a glue for this purpose for several reasons; but, my experience with vulcanizing plastics goes back over 50 years when I was assembling plastic model cars and I learned the difference between vulcanizing glues and what I would call surface glues.

Plumbers' glue for plastic pipes vulcanizes the plastic, meaning that it melts the plastic on the opposing surfaces and bonds them together with a chemical reaction. If done properly, the glued joint can be stronger than the rest of the object.

Read the label and apply the instructions as well as can be done for such dissimilar surfaces.

If it is a BIOS setting, removing the CMOS battery for a few minutes should clear it. Since you've already changed the battery more than once, it would seem that is not the problem. Considering what you already tried, it might be the motherboard itself or possibly the graphics card but my money is on the motherboard. Just to be sure do you have another graphics card to test with?

A:New Build no power-up: case's power supply or MB?

Well, I figured out the problem.
I am planning to re-do the older mini-itx system I have; it has gotten riddled with Trojan software for kids downloading games; it basically has been de-commissioned already.

So, I took the pico-psu power supply from that older computer, and hooked it up to the one I am making. Everything went perfectly.

So, I un-did that, removed the MB from case, disconnected the barrel-power connection from the case, unscrewed and removed the power supply that had been mounted in the case, put the pico-psu power supply back in place (I had to drill the hole for the barrel-connection out to be a little bigger since the pico-psu internal/external connection is threaded and held in place by nut with lock washer), and routed wires to be clear of cpu fan, screwed MB to stand-offs, and closed it all up.

now, everything is great. I like this linkworld case, but the power supply is worthless. I may try to get a few dollars back from the ebay vendor, to make me happy with a case that is less than what I should have gotten, but is working for me; I don't want to wait on returns, etc.

Not all motherboards are the same. To find the correct header pins you have to refer to the motherboard manual although sometimes the motherboard labels the pins clearly enough so you can figure it out. However, with the motherboard installed in the case, it could be difficult.

If you can't find your manual, try going to the motherboard's manufacturer site to download a copy of the manual (usually a pdf format). If you have a major manufacturer made PC (Dell, HP, Gateway, Emachines, etc.), you might have to try their websites. Good info from those sites might be hit or miss.

I am running a "private party" built P-II 333. I have recently had installed :

128 PNY PC100 RAM (upgrade from 2-32's)
Reused one 32 stick for a total of 160 RAM

Added a CD-RW 8/4/32 as slave
56x CD-Rom as master (old 40x apparently went bad)

Nothing I thought....

Now my system will not power up with the front intermittent switch unless I turn the switch off at the rear of the machine for 20-30 seconds. I turn the rear switch back on, push the front switch and the unit powers up normally. The unit is housed in a heavy piece of furniture that is difficult to move. This makes access to the rear switch difficult

What could have happened during these installs that would cause this change and what can I do to fix it??

A:Challenge! New M/B - New Case - No power!

There could be a short between the motherboard and case. it might be advisable to pull the motherbaord out of the case and set it up on an antistatic surface. Then only connect the powersupply, CPU with fan, one stick of RAM and the video card. This is enough to get the computer to turn on.

The jumpers mentioned are not the cables from the front of the case. they are little plastic caps that sit over two pins. Make sure the Clear CMOS jumper is in the normal and not clear position and that any Front Side Bus(FSB) jumpers are set right fot the CPU - refer to the motherboard manual for postitions of jumpers.

Of course, I checked the plugs, wires, switches, etc. I had to press the power button MILLION times before letting the computer to start and boot. Even after changing it to new case and new power supply, I will still have to press power button MILLION times to turn the computer on. Maybe my old motherboard causing this power failure? What can be other possibilities causing this stupid problem?? Please Help!!!

Okay, so this is a continuation of this thread: Help with Front Panel/Power Button Connector

Okay, so I don't know why, but when I have the 24-pin connector for my motherboard halfway in (or halfway out, if you're that kind of guy) all of my led fans kick on, but none of my front panel configurations can turn it on. Please see the above thread for more information!

Usually we don't use the power button on my custom-built pc, since we generally just leave the thing on all the time. So I noticed a few days ago when I did use it that it was sticky, like dust had gotten in around it or something. Then, a few days later, the pc started shutting itself off, at random, but usually within 5 minutes of turning it back on.

It's gotta be the power switch, right? And are these easily swappable? This one came with the case, built-in. I've never even tried to buy a replacement switch, so I have no idea. Hopefully I don't need to buy a whole new case or something.

Thoughts? TIA

Hi Now I have my new Motherboard and CPU up and running Socket A FSB Duron Everything works great except everyonce and a while usually after being on for a hour or more the computer starts making a funny noise every to seconds It is the sound the power switch makes when it shuts down But it doesn t shut down The graphics sometimes freeze for a split second but othere than that nothing happens becuase of it Is it the switch shorting Maybe the power supply is bad or not enough W The power LED switch is not connected I could not find the pins for it There is a casfan sure PSU? not switch CPU or power or hookup where the pwr LED was on my old board Could this be shorting on the frame of the case Or maybe is the CPU overheating even CPU or power switch or PSU? not sure with the fan It is a good quality fan made for Athlon s and other Socket A s which mine is Thanks for your help nbsp

I have a Dell Optiplex 240 that just quit getting power. I changed the powersupply and connected all of the cables correctly. I have tried different outlets and cords but still no power at all. I am guessing that it has something to do with the power button. How does this swith connect with the motherboard and how could I get the face cover off to make sure that I am getting a proper trigger. I have the P.C. open but it is really hard to get to or even see the internal side of the power button with out ripping the face of the P.C. off. Can anyone give some advice that has maybe ran into this same problem?

A:Bad Power Switch Please Help!

The wires from the case usually connect to a set of pins located in the front left corner of the motherboard (follow the wires from the front of the case). The small plastic connectors at the end of these wires hopefully will be labeled as will be the pins on the motherboard although the writing is not easy to see. On some cases the wires might be bundled together into one block connector--I don't remember if Dell does it that way, they didn't used to.

Anyway look for a connecter that says PWR or PSW or something similar. That wire comes from the "power" button on the front of the case. If you remove this connector and use a small screwdriver to short the pins touching the two pins that the connector went to you are
bypassing the front case switch. If your system starts up when you do this then you'll have a bad switch.

Hi all,

I just bought a new Stealth-S 375w case...and I want to know, should the fan power up when I switch on the main power switch (at the back)?. I noticed FrontPanel cables and I dont know if this should power on the machine if they are connected.

Hey guys,

A machine I have here (WinXP machine, though I dont think it matters in this scenario) will not boot up. It turns on (I can hear the fan going) but does not even get to the BIOS. There is a red light illuminated on the front of the case that usually isnt lit. (The symbol next to it looks like a cyllinder).

Any idea what's up?

A:Computer will not power on, red light on case

I inspected the CPU fan and it looks to be off axis and wasnt spinning right. Strange that I didnt hear a noise.

I then took out the processor to find out that the thermal paste between the heatsink and the cpu was singed...

Could that be it?

Hey I ve been having trouble with the power switch on my Cooler Master Centurion case It seemed to Problem Button Case Power be working fine for a short while then at one point my computer randomly turned off When I tried to turn it back on the computer would boot up and then shut off seconds into it It was acting as if I was simply holding the button down and then doing the standard ATX delay to shut it Case Power Button Problem off I disconnected the switch from the mobo and shorted the pins to boot up just to be sure and as I suspected everything works fine I left it off for a day or two and tried again with the same problem It seems like it s working for a short while and then without warning it shuts off again Cooler Master has said they would provide me a new one but I was wondering if there is perhaps Case Power Button Problem a way to fix it without having to send parts back and forth Any thoughts are appreciated Thanks -Mike nbsp

Hey everybody,
I have a case without power supply switch port and as I already know if I want to replace the power supply I have to find one without an power supply power switch on the back of it and I looked hard on newegg and on tigerdirect. I wanted an antec but thats out of the question because all 20 of them that newegg sells have switchs on them. The only one I found without a switch so far was on tgierdirect and its only 230w and thats what I have now. Also how many watts do you think I should get? Thank you very much

A:Power supply fitting in case

I am interested in adding some case fans to my computer. Inparticular one 60mm and two 80mm, and I was wondering in if my computers power supply could handle this. I have a 250W power supply and:
* Intel Pentium III Katmai 500MHz O/C At
* Just Cooler 25.5 CFM Triple Fan Heatsink
* DFI P2XBL R.D. Motherboard
* 524MB PC 100 SDRAM
* Dual IBM 13.5GB ATA-66 7200RPM 2MB Buffer
* ATI All-In-Wonder Pro 8MB AGP Video Card
* Dual ATI Xpert 98 8MB PCI Video Card
* Toshiba 3rd Generation 4.8x DVD-ROM
* Ricoh 6x4x24 CD-WR
* 56K V.90 ITU Fax Modem w/Voice Mail
* 3COM EtherLink XL TPO 10MB Ethernet
* Logitech Cordless iTouch Keyboard
* Logitech Cordless TrackMan Wheel USB -
PS/2 Port

Also if it helps there is only one more power plug left from the PSU, I don't know if this has any bearing though. I appreciate everyones input.

A:Power Supply going to be enough for case fans?

Not sure but you could get Mother board monitor It will track your voltages..

Hey all,
Im just wondering if anyone knows of any ATX tower cases out there, preferably with an aluminium/black finish and front door, that include a power supply capable of powering a Pentium 4 3Ghz that may be overclocked to 3.5Ghz in the future?
I haven't found any solutions where the case includes a powerful enough power supply. I'm looking to buy from England for about €150 / stg£90-100, and thats how I want to buy them, together in one package.


I have been looking at Chieftec Matrix and Scorpio cases which include 360w and 340w power supplys respectively. Are either of those power supplies capable of powering a P4 3.5Ghz?

I just replaced a motherboard (with a m758LR - pcchips) on a clone.
I tested the power supply with a power supply tester (all leads show green).

The computer does not turn on, the cpu fan and the chassis fan turn on for a fraction of a second after I turn off the power button.

I tested the power switch once with a multimeter - it showed no power.

Anybody have any suggestions other than retesting the power switch?

I don't think so you might need to RMA your machine.

where can i get them, i cant find them anywhere, mine snapped off by accident when my memory card fell down my comp, mines in like 1 thing an orange and white wires for the power sw and red and white wires for the h.d.d led, sorry i completely dumb to this

many thanks

A:h.d.d. led power switch cables

OK, exactly what broke off? Attached is a picture of kk connectors which I guess are what you are describing. Did the connectors just break, OR, did the wires break also?

The only place I know you could get complete new wiring assemblies would be from the case manufacturer, if they have them for sale.

If just the connectors broke, you can get new connectors here;

scroll down the page and you would need a pack of the BLS-2 (you have to buy a pack of 50 but they are cheap). If either of the connectors are 3 pin you would also need a pack of part # BLS-3.

If the ends of the wires broke off you would also need a pack of pins part # BLS-PIN/F and a crimper Part # PHT-DS-STMP

If you have a repair shop near you they should be able to replace the ends for you if the wires are broken off at the pins. Unless you do a lot of these on a regular basis kk connectors are a little tricky to crimp, and I suggest that you let a shop crimp on the new pins for the connectors, because if they are not crimped correctly the pins will not stay in the connectors.

The power switch on my Compaq Deskpro went faulty, so I bought a replacement generic switch. Installation seemed no problem, when I switch on power lights come on, but only for a few seconds, then system shuts down. I don't think I did any other damage when replacing the switch. What should I check out?

I've got a problem with my CPU

Whenever I switch on my computer,
I push the POWER ON button,
the CPU powers up,
the harddisk and cd drives all power up,
then everything comes to a standstill (all lights still on)
There's nothing on my monitor.
Monitor still in standby mode.

then i will have to press the RESET button,
then my bootup can continue.

anyone can help me with this problem??

A:Problem with CPU power switch

Hmm can you tell us more specific?

I mean this could happen if your monitor jacks are plugged out,
Graphics card damaged, heatsink installed wrongly, Some other components are plugged out. Even the mainboard battery is exhausted. btw the problem should not be the switch, otherwise nothing will happen if switch is spoilt...

try to write more about your system such as system specs and when is this thing started?
