Computer does not turn on

Question: Computer does not turn on

Hi. Recently, my younger brother, told me that his computer could not turn on. So, the first thing I did was to check if it was his charger's issue. It seems like it wasn't. Then, I decided to try again with my computer's charger instead on his computer. Well, I noticed something. When I plug my charger into the power outlet, there would be a light to signal power is flowing. And when I plug it into my own computer, it stays on. However, when I plug the charger into my brother's computer, the light vanishes. Is there something wrong with his computer? Thank you !

Preferred Solution: Computer does not turn on

I recommend downloading and running Reimage. It's a computer repair tool that has been proven to identify and fix many Windows problems with a high level of success.

I've used it in the past to identify and fix everything from blue screens (BSOD's), ActiveX errors, corrupt files and processes, dll/exe/sys errors, recover lost memory, Windows update problems, defragging, malware removal etc.

You can download it direct from this link (This link will automatically start a download of Reimage that you can save to your computer.)

Answer: Computer does not turn on

Sounds like his charger is bad. If your charger works, and his doesn't, it's bad.

I have a bit of a strange issue with my computer. Forgive me if I'm a little too descriptive, but I'm not sure which details are relevant and which are not for such a problem. First, the specs:

Model: eMachines T2984
Operating System: Windows XP Service Pack 2
Processor: Intel Celeron D Processor 340, 2.93 GHZ, 256K L2 Cache, 533 MHZ FSB
Power Supply Unit: Bestec Model: ATX-250-12E REV: P7
Motherboard: I can't tell, but it appears to be an Intel motherboard by the number of Intel labels on it
RAM: 512 MB DDR SD originally, added 1 GB a couple of months ago
Let me know if you need anything else...

Yesterday, I got home from shopping around 1PM, and I tried to start the computer. I pushed the power button, and nothing happened. I checked all of the cords, and they were all plugged in. Not knowing what else to do, I opened up the case to see if there was something obviously wrong. The only thing that I noticed (other than a bunch of dust) was that the power supply unit was still hot. I shut the computer down about 5 hours earlier after about 20 minutes of use, so it seemed strange that the power supply was still hot. I unplugged the computer just in case there was some sort of fire hazard.

At this point, I called a friend who suggested that the problem might be with the motherboard or the power supply unit.

A few hours later, I plugged it back in to try to get it to work. As soon as I plugged it in, the entire unit suddenly started "running" by itsel... Read more

Answer:Computer Doesn't Turn on, Fans and Some Lights Turn on Automatically

I would suspect that the Power Supply Unit (PSU) is going south. If you have a spare one laying around, install it and see if the problem goes away.
You can buy a new,better PSU from Newegg for about $40.00. I have used a Thermaltake 430 watt in one of my machines for some time now and it works well.
You will have to check the size of your PSU to be sure a new one will fit into the eMachine.
Here's the page with that PSU on it. It's the last one on the list.

I just put together my first computer 6 months ago. It abruply shutdow in the middle of writing a paper for school. I couldn't turn it back on right away. after trying a few times, it turned on. All the fans are working even the fan on the power supply, the motherboards lights are on. My graphic card in on the motherboard. I think it might be my power supply because when I first put it together I didn't plug in the smaller power connection to the motherboard and the same thing is happening, black screen. It's like my computer isn't giving my monitor any feed. I will have more info when I get home. I can't get in to bios or safe mode.

after serching all night to find out why his computer is in limbo, i leave my brother's house without finding needed help. his computer won't turn off...the fan, a couple little lights until he unplugs it from the wall. first, the computer did a restart all by itself, he said, then it would not turn on, except the fan and little lights inside that won't turn off. he took out the hard drive and it functions in his other computer...he puts the hard drive back into the new computer and it will not turn on or completely turn off that fan. he tried the "hold the on/off button for at least five seconds" step and nothing changes. he has had the computer for a year and a half, so he really wants to figure this out. how can he even get it to turn on so he could do a safe start up? so far we cannot find a way to troubleshoot. he have checked the cords, perhaps there was a freeze up that began this loop and that's why the fan stays on? please say this is something you have heard of and there may be a solution. the advice we have found usually goes back to buying a new computer. thanks in advance, tea

I am using a client computer that is connected to a modem via a LAN cable which is in a neighboring house as far as about 50 meters. The host computer is there. The host computer is only using Internet Connection Sharing (without a router) to share its Internet connection with me. Within this network there are only two computers, the one I use (as client) in my house and the other one is the host computer as I mentioned earlier.

How do I know that the host computer is being turned on or off?

The purpose is to know so that I can use all the bandwidth from the modem when the host computer is not turn on. Because there are no restrictions on bandwidth from the host computer, and I just wanted to use all the available bandwidth only when the host computer is not turned on.

Both computers use Windows 7.

I use my laptop for school and, by keeping it on power saving mode, usually get through two school days without charging my laptop. Ever since I've downloaded Windows 10, (1) my computer doesn't shut off all the way when I close it, which drains the battery, and (2) every time I charge it, it turns off the power saving mode, which is really annoying. This is especially annoying when I don't notice it isn't on and my battery drains even faster. Is there any reason it won't turn off? Is there a setting I can use to keep the power saving mode on at all times?

Answer:Why won't my computer turn off all the way and why can't my computer stay on power saving mode?

Your system might have a virus, try to scan using Malwarebytes, Superspyware , Trojan-Killer. Restart your system then try to download Hitman Pro then Run it. Then optimize your system using Ccleaner. Hope this would help.

First of, my monitor exhibited signs of flickering during start-up, but only minor ones and would just stop at the 'Welcome' screen of windows so I didn't give it much thought. Iv'e been using it with the cpu the same time I bought the monitor.

But after some time, the flickering got worse. It went from 1-2 second interval flickers to a whole 10 seconds of blackness before it showed anything.

Now,Iv'e got a new cpu but still using the old monitor. After a day or so, the monitor exhibited the first symptoms of my first cpu, so I just dismissed it. But after a week, It got a hell worse, before I even start-up my computer, the monitor doesn't show Analog/Digital at the top-left corner of the screen. PLUS my cpu keeps restarting after I pushed the ON button after 10 seconds or so.

My question, Is the monitor responsible for the restart and what could be the reason for the flickering?

Thanks for a fast reply.

Welcome Pokeman5 to the windows 7 forums.

The graphics card might be your culprit. Please update your system configuration settings under user cp so that others can maybe help you.
Usually the monitor won't stop your machine from booting. The graphic card most likely be the cause.

There is also the possibility that your power supply could be defective or going bad. Lots of possibilities.

i also recorded a video of how its sounds like:
so please help/B]

Answer:Solved: computer beeping sounds when i turn on computer

There are three possibilities here, all related to your memory.

1) You have forgotten to fit your memory back in.
2) Your memory isn't properly seated in its slot(s)
3) You have killed your memory because of not following antistatic procedures.

I'm suspecting it is either 2 or 3.

As the title said, my computer freezes during games. When it freezes the screen just stop at the last frame (so no black screen or anything like that) and I can hear the game for about a second before it turns to a low clicking sound. At which point I have to manually shut down the computer and restart it. Nothing else works. Then I get the usual question of how I want to start the computer, I always pick “start normally” and it’s like it never happened.

I think it’s because the GPU is overheating, because that’s the only component that’s really hot. When I check the temp while playing it’s usually building up to about 60C (24-30C on idle) and stays around that number. And it fells really hot when I touch it after it’s happened. The only problem with that theory is that I can play every game out there usually on the best setting (haven’t tried every powerful game out there) and not a single problem with lag or such. Then again, I’ve never had that problem with MW3, and the temp stays around 50C on that. Not to say that the GPU is really that great. It’s average at best, but I’m not a hardcore gamer or anything so figured I didn’t need the best.
I built the computer myself in June 2011. And it went fine without any problems until maybe 6 months ago, not really sure when it happened.

Ok well, my computer is pretty old, but its not THAT old, it has always worked very well, and all of a sudden one day it froze and i tried turning it off but when i went to press the power button it wouldnt turn off, no matter how many times i pressed the power button. so i had to turn off the power switch in the back of the computer. it did this consistently so i decided to format my computer and delete the partition stuff like that, but it still did it, and i even virus checked and there were no viruses.

my computer freezes out of nowhere at random spots (startup, windows, my desktop, etc) and when i try to turn it off the power button doesnt work so i have to turn it off by turning off the switch at the back of the computer, please help me, i don't know whats going on!

Answer:URGENT PROBLEM: Computer freezes, but can not turn computer off

Try holding the power switch in for at least 4 seconds. There is a entry in BIOS for instant off and 4 second delay. Yours is probably set to 4 seconds. Delay is good as it prevents accidential power offs from hitting the switch by mistake.

If you are hiolding the switch in and it isn't powering down there are two possibilties. Switch is defective or connector has came off the header.

I am having trouble with a 6 month old IBM R51 laptop - when I select TURN OFF COMPUTER from within Windows and the START button - the computer sometimes hangs and will not shut down. I have to press the power button to reset. Any idea what could be causing this?


Answer:Computer Hangs When Turn Off Computer Selected In Windows

Welcome to BC! There are many possible causes, however there is one common cause. Often XP's exit sound file gets corrupt and if it does not run then XP won't shut down. I am not sure based on what you have told us so far if this is the issue or not, but let's see:Go to:Start > Control Panel > Sounds, Speech, and Audio Devices > Sounds and Audio Devices > Sounds tabUnder Program Events scroll down until you see Exit Windows. Highlight Exit Windows by clicking on it once. Then under Sounds choose None. Click Apply and finally OK. Reboot if possible, or shut down computer and restart manually. Once it is up and running, shut down computer by going to Start > Turn Off Computer. See if it will shut down on it's own now.If it does, the only difference will be that you will not longer hear the 2 seconds of music that XP usually plays as it shuts down.

Hi TheRealDanny.

The crash dump (a Stop 0x3B one) is not saying anything in detail about the probable cause of the BSOD).

Test your RAM modules for possible errors. How to Test and Diagnose RAM Issues with Memtest86+
Run memtest for at least 8 passes, preferably overnight.

If it start showing errors/red lines, stop testing. A single error is enough to determine that something is going bad there.
If it does not show any error, enable Driver Verifier to monitor the drivers. Driver Verifier - Enable and Disable
Run Driver Verifier for 24 hours or the occurrence of the next crash, whichever is earlier.

Why Driver Verifier:
It puts a stress on the drivers, ans so it makes the unstable drivers crash. Hopefully the driver that crashes is recorded in the memory dump.

How Can we know that DV is enabled:
It will make the system bit of slow, laggy.

Before enabling DV, make it sure that you have earlier System restore points made in your computer. You can check it easily by using CCleaner looking at Tools > System Restore.

If there is no points, make a System Restore Point manually before enabling DV.

Just got a new to me P3 computer up and running. Sometimes during star up it does not recognize the PS2 keyboard. Which makes it hard to go into my password protected User ID. When trying to shut down it will keep a few things running like some fans and the CD drive. But it does not sound like the Hard Drive is spinning.

If I use the XP to shutdown it goes into this limbo stage of neither off nor on, same goes for the power button on the front of the computer. It will either start up the computer or turn it to the limbo mode. Upon starting up, I can use the mouse to get it all the way into a non password protected XP users screen but can't do anything without the keyboard working. In the process of setting up I have had everything working earlier today but this keyboard and limbo status has been an intermitent problem. What should I try?

Hi all.
I moved out of a 14-year-old case (Gateway) and into an Ultra brand Gladiator mid-tower.

I have an EVGA nForce 650i Ultra Motherboard, and a "Power Up" brand 450-Watt power supply.

The setup worked fine in the old case, though Windows was freezing regularly after 15 minutes. I figured that was related to the hard-drive, since it wasn't tightly mounted, and I wasn't using enough cooling fans. So I got a new case and cannabalaized a fan from an old computer.

The power outlet and cord are good, and I swapped out the power supply with a 230 watt unit, and pulled the switch from the old case, but neither powered on the computer. Nothing seems out of the ordinary with the switch on the case I bought.

Did I buy a defective unit? Is there something I'm missing or should try again? Something else? Thanks for the help.

Answer:Changed computer cases, now computer won't turn on

Have you considered that going from a 450 psu to only a 230 might have something to do with it?

Is the motherboard shortening out by any part of it touching the case?

Hello there, recently, I've been having an issue with my PC. Randomly, all peripherals (Monitor, Keyboard, Mouse, Speakers, etc.) turn off, but the computer stays on, and I need to turn it off by flipping the power off, and once I turn it back on, it boots normally and such. Like I said, the times this happens seem to be completely random, though I believe it has only happened at night, but that may be just coincidence. I have used virus scans, and nothing has come up, so I don't believe that's the issue. I haven't made any significant hardware changes recently either. Does anyone have an idea of what could be happening?

Thanks in advance

Alright, alright.. this happened to me once before.. although it wasnt exactly the same situation.Im not 100% sure why this happens, but sometimes plugging a device into the USB can cause it to completely lock up (freeze), after wich u can only close it via the reset button on the front, or in extreme cases the power cable on the back.Now, when this happened to me the first time, i thought it was something faulty with Windows so i have it installed again. However the problem came back, somehow the PC would totally freeze every time i plugged in that device. The only thing that does not overlap, is that u say ur PC does not turn on. Mine turned on but then froze again after only a little while.You say that ur PC DOES turn on, but the monitor dosent display anything. Does this mean that the monitor displays the "no signal" colorful hovering box, or is the monitor competely turned off and not even displaying the orange light next to it's power button. As in, is there no difference beetween when its ON or OFF?The PC working but the monitor staying blank (ON, as in the light near the power button is working.. but u DONT get the "no signal" box, as in its just black and nothing else) means that there is probably something wrong with ur graphics card. If there IS "no signal" then its probably not ur graphics card but some bigger problem.Can u answer my questions, and also get another monitor to test with this PC in order to see wich one is fualty?If ur ...

I have had some issues with my computer. Supposedly all is fixed says the tech I was using. Sadly this is not the case. He said my mobo was bad and it was still under warranty so got it replaced. He said my hard drive was bad and it was still under warranty so am getting it replaced. In the meantime I am using my back up slave drive now as my master drive. I try installing win2k on it but no go. After it says it is installed and reboots I just get a black screen with a blinking cursor. Tried that several times. Now when I turn on the computer I get a high pitched whining sound. This tech guy has taken up close to 6 weeks of time and as far as I can see with no resolution. So I have come here to see if anyone can give me any suggestions or directions to procede. Thanks.

Answer:Computer will not turn on

That's a weird one..I couldn't tell ya. I've never heard of that problem. It can't be a video issue since you do have a visual. Sounds like you'll have to wait it out until you get a new hard drive.

I plugged the charger in which the light on the adapter stayed green but the computer light didn't show it was charging. I also tried removing the battery, holding the power button for 20 sec, then plugging in the charger to turn on but it still didn't work. I ordered a replacement battery and charger and it still will not come on. Could it be the charging port needs replacing or could it be the motherboard?

Hey everyone,I have owned my computer for about two and a half years now, well three months ago it died so i had the motherbored replaced and i finally recived it.  Well i hooked everything up like its suppose to be, turned on the computer and it booted up just fine.  I started pulling some files of it onto my ipod so i could get it off.  Well about half an hour to an hour and it shut off.  So iwas like ok, maybe it over heated.  I did my best to check the fans, i even touched the heat sink to see if it was to hot and it wasn't bad.  I took off the other side of the case and put a fan into.  Well i waited about fiftieen minutes and i tryed to turn it back on but nothing happened.  Now could of the CPU burned up, i thought that it was programmed to shut itself off before it did that.  I have checked the video card, sound card, the power supply, the only thing i havn't checked is the motherbored its self.  I have taken the motherbored out of the case to make sure that it wasn't getting grounded but its not.  Any suggestions please thank you.  Im going to let it sit for a day to see if anything changes

The other day I had a very quick power cut in my home. My computer was turned on at the time and obviously when the power cut out the computer went off. When the power came back on I attempted to turn my computer back on with no success. I tried unplugging everything and plugging it back in, and tried turning it on again still with no success. I thought that the fuse might have gone in the plug but the monitor is stiull receiving power, and as this is connected to the power source through the tower I assume the plug is working fine! Does anybody have any ideas what the problem is and how I can fix it? Even if you can give me and idea of what to look for when I take the side off and have a look at my motherboard. I'm at a bit of a loss at the moment. Thanks again everyone. p.s. Im rubbish at knowing what technical info I should include so give me a shout for more info on this.

Answer:Can't Turn Computer On

The power is not reaching the Mother Board. Hence, i guess that means either the power supply of the tower has broken or the Mother Board is damaged. I would first test it by replacing the power supply unit. (you can borrow ....). If you are lucky & it works, you can buy a new power supply unit. Else, u could be in trouble as the MBoard might be damaged.

My pc was turned on when i had a power cut and it obviously switched off. It now won't turn back on. All the lights are on but nobody seems to be at home! Could something have blown? I'm not exactly a computer genius so not sure where to start. Please help!

Answer:Computer won't turn on

Ok, If your PC works well before the deadly power cut, and now 'died' after that, there's no need to think much.

& what do you mean by that 'power cut'? do you mean it's a lightning strike that cut the electricity power of your house? If so, maybe the lightning sent a powerful source of power from your house's electricity to your pc (that your pc power supply couldn't afford to bear the overwhelming power sent by the electricity flow (wire). This is also possible to kill your pc. I hope you understand what I mean (fheww.. english is sure tough to 'perform')

1. Turn on all power, push the 'ON' button of your CPU. This won't turn your computer ON but the purpose why I ask you to do this is to check your computer power supply. Give a sharp attention to your power supply fan (usually visible from the back of your CPU). While the 'wall' power is on, try to push the ON button continuously while checking whether your power supply fan is spinning.

2. Does it spinning? No right?? If not spinning, then you don't have to use that power supply again since it's 'dead'. Try replacing it with a new one. This surely solve the problem. (I think).

Don't know if this is the correct forum, but here goes. I just upgraded my motherboard, processor and memory. I've solved most issues that come with upgrading, but I've got one I cannot figure out. When I turn off my computer, the computer turns off as it is supposed to do and then, after several seconds, starts back up again and boots back up. The only way I can stop this process is to trip the switch at the back of the computer.

first of allll, i can't tell you my computer specs at the moment because i can't turn it on. and idk how to find that out without turning it on soooo (my dad built it, ok, i know, cries)

anyway, i will explain to you in detail what was happening that led up to the current problems.

playing computer. all is fine. leave for an hour, come back, and computer is off. i tried turning it on, and the fans and lights turned on for a moment and then turned off. switched outlets, powered on computer, and WOAH it worked again. i got on the internet and chilled for a few minutes, and then it turned off again. tried to turn it back on, no power at all this time. no fans, no lights. this problem persisted, and nothing i did changed that (checked to make sure everything was kosher on the inside (it was)).

so i took it to a repair store and after giving them time to look at it, they called and were like "yeah we have no idea whats wrong with your computer, we're gonna check out your motherboard" and the very next day, "uh, your computer appears to be working fine again!!!!" bring it home, plug it in to regular outlet, and no power. so much for my computer being fine! so we switched the storm/surge breaker thing we were using and this time the computer turned on and seemed fine for a day. today, just now, though, i was playing a game and the my monitor started acting like the computer wasn't on (it went into power save mode). the computer didnt turn ...

Recently i bought a new custom made computer from the online store Nirv Australia through ebay. I used it well for 1 day just installing anti virus and a few games and such nothing major, and then last night i went to dinner with the computer on and when i came back 20 mins later it was off. I cannot turn it on now. Although everytime i hit the reset button on the motherboard or turn the power off and then on and try to start it up all the fans and the blue lights will start up for a split second, (the lights flash blue and the fans move a tiny bit).

I've contacted the maker through email but they havn't replied and i was wondering if it was a small issue that could easily be delt with from the help of someone on here.

I have this computer that I'm working on and it won't turn on. I swapped out the PSU and still no luck. I inspected the mobo and saw no blown out capacitors or burns or anything that would suggest a power surge or fried mobo. I have even tried jumping the switch by touching both pins on the mobo together. All I get is a little twitch of the fans starting to spin for a split second and then they quit. It acts as if the mobo is being grounded out, but I suspended the mobo away from the case and it's still doing it. Is the mobo bad or what?

Edit: The motherboard is an Epox EP-8K9A1. AMD Socket A (462).

if you have replaced the PSU it sounds like the mobo you dont have to see signs of damage for it to be bad little bit of ESD will do the trick.

I don't know if this problem is already in here but I wasn't about to look through 50 pages of topics to find it if it is.
Last night the power went out at our house, my computer was on, and obviously it went off, I had a surge strip hooked up to it and all that stuff, but for some reason my computer won't turn on. When I press the power button the lights will flash on and the fans will start and will seem to turn on but there are no external beeps. Then I can't get it to do that again unless I flip the power switch in the back a couple times unplug it and press the power and restart buttons again. Then maybe I will get it to flash but not always.
I have a pretty powerful computer with a nice video card which uses up a lot of energy, I was wondering if it maybe was my power supply. My brother is very good with computers and I called him he said that maybe I need a more powerful power supply. Mine is 370.5W and he said maybe put in a 400W one. Is he right? Or is it another problem?

Answer:Computer won't turn on

if you had a power surge, it could have goofed up your computer. just beacuse you have a power strip doesn't mean you have a surge protector. it probally is your psu but the psu could have burned out somthing int eh computer.(no likely, but it could have happined) and if you do get another psu, jump up the wattage a bit more than just 370W to 400, go for at least 450, if you decide to upgrade later you will be happy you got it.

My computer has been working fine for about 8 months since I built it, and then today it randomly shut itself off. I unplugged it and let it rest (assuming the processor was overheating), then tried again and it does nothing. I've also cleaned the processor/heatsink and applied new thermal solution. There's no way for me to actually check the temperature since it won't turn on, but I'm pretty sure overheating is out.

You don't say what OS you are running. In most all the 4 second shutdown is standard and can be altered in CONTROL PANEL, POWER OPTIONS. Leave it alone and just tap the Power button. It should shut down same as if you went through the Shutdown procedure. Easiest way.

Hi, my computer won't turn on. It's weird, i've tried to diagnoise it, but can not come to a conclusion of where the fault is.

I have been usin my self built amd dualcore/asus mobo computer for several months now. Works perfectly very stable with no problem.

The other day when i was usiny my computer, i suddenly smelt this burning smell from my comp, it immeadietly turned it off. I looked inside, couldn't see where was wrong, so turned it back on. A while later the smell came back, then my comp just shuts off, and will not turn on again(no twitch wat so ever when i press the power switch).

I opend the case and had a look inside, the onboard fans seem to twitch for a second when i press the power switch, but thats about it.

I suspected it was PSU problem. I had a new skyhalk 500W psu lying around so i plugged it in. Same deal as before, but however this time, the fans(cpu, mobo, vidcard) will spin up fine as long as the power is not plugged into my SATA hd. As soon as power is connected to my SATA hd, nothing moves at all as before(when i press power switch ).

So i go pull out a old ATA hd from my other comp, and plug it into this dead comp, now everything spins up, but still i can not get my bios/mobo screen to load up(monitor no signal).

Answer:Computer won't turn on.

I'd try another known good power supply in this PC, try one from another PC if you have one otherwise you will need to borrow one or take it into a repair shop to be tested.

Computer will not turn on. Sounds like it is starting, but screen won't turn on and computer stops making noise, doesn't sound like it running anymore. But the power light stays on. Already plugged and unplugged all power cords and power strip, still nothing. Worked fine yesterday.

I just got a used computer that wasn't used much.  It was in a garage for 4 years or so.  We hooked it up a few times over the last few months and everything worked fine [smiley=thumbsup.gif].  The computer didn't have anything in it, except what was pre-installed.  We decided to keep it so I hooked it up and played around with it (not online) for a few hours.  I shut it down.  2 days later it wouldn't turn on.  It's a Dell with Windows 2000.  The power button blinks yellow, the keyboard lights come on and the monitor lights come on.  That's it.  We have tested the outlets where it  is hooked up and that's all fine. I know a little about computers as far as programs and things like that, but this has me and everyone I know, baffled!! :question  This was the second computer in two days that quit on me [smiley=angry.gif].  They were both fine until Monday.  The other is an OLD Gateway with Windows 98.  That one gets as far as the boot screen and shuts down.  If anyone can help me, please, I would appreciate it.  [smiley=cry.gif] I need one or the other to work, preferrably the Dell.

OK, so I was playing some earthbound via SNES emulator on my old XP. I was playing it for a little under a half hour when suddenly my PC went out. It sounded like it was off but the power LED was flashing like it was in sleep. I hit the power button to try and wake it up and nothing happened. I mashed buttons on my keyboard and nothing happened. So then I held the power button to turn it off, and after what seemed like an unnaturally long time it shut off.

After that I tried to turn it back on and nothing happened. I tried different outlets and power cables and nothing happened.

I have no idea what to do, somebody please help.

Answer:Computer won't turn on

Most likely a power supply failure. Replace the power supply and test the system again.

My computer won't turn on at all anymore. My monitor is working for sure. I can see everything light up inside my case so I don't think that it's a problem with the motherboard. My HD was making some loud clicking noises so I'm assuming that isn't the problem. How can I check to be definite that it's my HD and not my GPU? I'm running an old 8800GT, but don't think it's dead.

edit: My bios isn't loading either now that I think of it. Before, if I turned it on and off a few times eventually it would boot. Now, it's just a black screen. All the lights are on for it though.

I have a problem with my computer. It just won't turn on! Its an eMachines desktop with a Celeron D at 2.93 GHZ, 512 MB of RAM, and a 80 GB hard drive at 7200 rpm. It can't be more that 13 months old, and I think the model number is something like T4010.

Yesterday evening I went to turn it on only to find that it was totally unresponsive. Nothing happens, *at all*, when the power button is pressed. No sounds, no lights, no internal activity.

The computer and all accessories are plugged in. No wires/cables are damaged.

The only thing I can think of - and quite an obvious cause of damage - was the giant lightening storm we had here. But the computer was plugged into a UPS battery back up and surge protector, a very expensive one (Sigh). It was working and fully charged during the period I was away form the desk. Further, the power to the house never went out and the lights never even flickered. I tried another PC (which was also on and running during the storm) with this PC's cables and the UPS, it works.

It is completely protected by Norton antivirus, and supplemental AOL protection. (Not conflicting.)

I opened the case and didn't observe and physical damage. The power button is mechanically functional. (A small green light is visible on the motherboard when plugged in, but everything else looks totally dead.)

Any ideas what this might be? Thanks.

Answer:Computer will not turn on.

You could trace the power button wires back to the motherboard and make sure its seated on the pins securely. There is a tiny chance that it somehow worked loose (heating/cooling cycles). The switch also could have gone bad. To test that figure out what 2 pins it goes to and short those out with a flathead screwdriver, it doesn't have to be a continous connection (in fact that won't even work) just needs to make a connection between those 2 pins for about the same length you leave your finger on the power button.

If that fixes it then there you go. But it probably won't, in that case your power supply or motherboard could be screwed up. Check the cord plugging into the computer to make sure its getting 110-120V that little green light won't always indicate a good power supply.

Hi Guys,
I have a Compaq D510 SFF with 1.8 P4/256RAM/80Gb IDE HDD , which isn't turning on, no motherboard light, no sound, no nothing, just blank.Then a few hours later everything would be fine, its been doing this for about two weeks now. If any of you have any suggestions it would be much appreciated.

Answer:Computer won't turn on.

Sounds like a Power Supply issue. Try to remove the power cable, wait 15 seconds so it can drain the power, move the voltage switch (red switch on back, you will need a pen or flathead) to 230, wait 10 seconds then move it back to 115. Plug in the power cable and test it.

My computer was working fine yesterday night and when I woke up today I tried to turn the computer on but it would not turn on. I tried every step you can do to make sure if it is the plug. My monitor is working fine. The motherboard LED lights are working so it can't be the motherboard.

I touched the red thing on the back of the PSU and the power was on but as soon as I let go the power died. So is my PSU broken? Idk wat to do please help.

Answer:Computer won't turn on

By "red thing" I'm assuming that's a reset circuit breaker. And if it keeps popping then there is an overload or short. It sounds like the PSU is the culprit, less likely but still possible is a card (video, sound card, network) went bad or the motherboard had something go (yes that does happen and not as infrequently as you'd think).

So I'd try a PSU and go from there.

I know this is a pretty general subject but that's where I'm at right now. I have had my computer off for a few weeks and just hit the power button with no response. PSU rocker switch is in "on" position and there is no visible trip indicator for any kind of breaker built in. Only visible things are the voltage selector switch (currently @ 115V, I'm in the US) and the on/off rocker switch.

I opened the side of the case thinking maybe the connector for the switch came loose (tower sits on the ground near a closet door, I thought it might be possible that it got hit somehow) but the connector is still firmly seated on the pins it's supposed to be (motherboard has a printed position map for that area).

I guess the switch could be out and maybe that needs to be replaced, but the feel and sound it has when I press it is as it has been for several years. Note that this computer was purchased in the summer of 2002. The only recent thing that I've done to it was replace a fan and replace the video card, but this was done about 9 months ago and, up until a few weeks ago, the computer was on quite a bit and had no issues.

I figure the experts here might have a suggested list I should run through to try to determine the problem. Any help would be greatly appreciated.

Your going to have to eliminate possible causes. Start with testing your PSU, you can easiliy do this by following the video.

Okay well my computer has been taking an age to start up for a while now but no matter what I searched for I never found anyone with a similar problem on other forums and thus could never find an answer. I can't really afford to go get it repaired right now so I've just been living with it for months; essentially I get the initial splash screen, the windows loading screen and then blackness for ages! Sometimes the screen is black for a good six to eight minutes, then a little cursor appears in the centre and I'm brought to the screen where I can pick which user I want to log in to. From there it's all fine.

Ever so often though, the computer just hangs at the black screen forever, so I have to power it down with a hard reset, then restart and a menu comes up after the initial splash screen asking if I want to run startup repair. Whenever I do that it seems to get me back working again (still with a very long boot time) but it will uninstall either Google Chrome or ITunes. I don't think it's because either program is the problem, I think it's just cause the updates get corrupted when I use the restore manager to reset back to a prevous working state of my computer. Either way, I re-install them and they soon work fine and dandy. My problem is now that the computer won't turn on at all. The black screen holds forever and the startup repair manager says this is a problem it can't fix and simply sends stats to Microsoft.

Hey all! I've had this problem ever since I got this computer back in 2004, and I know I should have done something about it before, but I just always hoped it would have fixed itself. (Ugh, I know, I'm dumb!) Here's what I'm using:

Shuttle I 8600B
Windows XP professional
Intel Pentium 4 3.40GHz
3.42GHz, 1.00GB of RAM

And the problem is that my computer doesn't turn off all of the time. I go to Start --> Turn Off Computer --> Shut Down (I am 100% positive I am selecting Shut Down), and it goes through the normal process of shutting down. It gets all the way to "Windows is saving your settings..." and then the monitor goes black (like it should!), and it sounds as if my computer turns off. Except it hasn't - everything has stopped running except, apparently, the fan and the process light.

I've waited over 12 hours for the computer to turn off in this stage, and it never does. The only way to get the computer off at this point is to cut the power entirely. Holding down the power button on the computer itself won't turn it off. Only pulling the plug or turning off my surge protector that my computer's plugged into will, and I know that can't be good for it.

I've researched this a lot, but I've always given up. One person with a related problem found that the problem was because of the ethernet cable, but even if I unplug that before shutting the computer down, it still doesn't turn off all of th... Read more

Answer:Computer Won't Turn Off

Interesting Problem.

Have you tried running any type of virus or spyware scan?? perhaps you have a virus emulating the shutdown sequence and then keeping the computer running, (although it is pretty unlikely).

Have you ever tried running the computer without the surge protector??? perhaps the surge protector is faulty and is supplying some sort of abstract current that is keeping the computer running.

The next step would probably be to test some of your hardware, run a check disk scan to see if your Hard drive has any problems, test the computer to see if the PSU is faulty and is supplying power when it isnt supposed to be, and finaly test with another motherboard, perhaps the connects on the board are dodgy.

I think the person with the Ethernet problem would have had a problem with the computer booting even if it was told not to not shutting down, as the otpion in the BIOS is to allow boot on LAN activity.

Alright, so I'm new to this forum, so please excuse if I'm doing something wrong. But a few months ago I purchased a custom-built desktop from someone. My intent was to use it for minor-gaming, and so I did. It worked for a month or maybe a little more than a month and all of a sudden one day I got home from school and I tried to start it up, and it didn't turn on. It was working fine the night before, and the next day, nothing. I don't know what could have happen, but my father unplugs things every morning before going to work, maybe that could have done something. I opened it up to look around. One thing was unplugged, that was the power LED, the other thing is the ATX SW however, that was plugged in. I messed around with it for awhile and nothing seemed to work. I then shifted the wires a bit, and what I got from it was a blue LED light on the power button when the system is powered on. That didn't happen before from what I recall. I also took out the PSU and tested it using the paper clip method, and the method worked, the PSU fan was spinning, but when I plug it back into the MOBO, it doesn't work, nothing turns on but that blue LED light on the power button in the front. No sign of power, no fan, or anything. I also tried to remove my 4gb of ram memory, that did nothing. I don't know what else can be done, help please? I spent a decent dollar on it..

Answer:Computer won't turn on!

Not sure what the paper clip method is, but it sounds like the PSU is bad. It puts out a number of different voltages so testing one part may not work. Do you have another one to try in its place?

It all started with my motherboard not picking up any IDE drives, so i turned the pc off, took all ide cables out and stuck them back in, and the pc began to boot and i had windows loaded. After restarting it, the motherboard told me no IDE drives were being detected again. So i shut the pc down... done the same thing, this time around though, nothing will boot/power up.

If i take the bios battery out for 5 minutes or so, the entire computer will have power running to it as soon as i put the plug into the back of the powersupply, this is without pressing the power button on the front, all fans and mobo lights are up, but the PC will not turn off unless i flick the PSU switch or simply unplug it, after doing this though it wont power up normally.

I guess this is a problem with the motherboard and will probably need replacing, i just want to really be sure this is the case before ordering new parts.

Answer:Computer won't turn on, help

You do not need to replace the motherboard, but you have work to do.
First, we need the brand and model of computer, brand and age of hard drive, and other details about your system... OS, power supply, memory, age of components.
Did the failure to detect the hard drive happen suddenly? What antivirus and antispyware programs are you using. It appears you have some infestations or corruption that needs attention.
Have you tried replacing your cables?
As I understand your message, you have two issues: Your hard drive is not detected, and your computer will not turn off when asked to do so by Shut down in Windows.

Welcome to TechSpot

Did you put the memory back in its original place? Press it down all the way, so that both white clips slot into the openings on the side of the RAM-stick?
And if you added RAM, is it the exact same type?
Did you switch off the PC and disconnect it from the mains, before you pulled that old RAM? If not, you probably blew that RAM and is no longer useable.
Try it with only one stick.

Ok, here's the deal:

I had to update my motherboard back in May, along with my video card and chasis. Everything was well and good until one day in July, my roommate was playing LotR: BfME and all of the sudden it just froze. Nothing happened whatsoever, I tried everything. So, I resorted to a hard reboot. Next thing I know it won't boot up. Nothing happens on the screen.

So, I took the compy back to the shop that I had worked with before to get the new mobo and such, and after some testing they claimed that my mobo (socket 478) went bad, so they got a new one under warrenty. Next thing I know I get a call from them claiming that it was not the mobo, it was my processor. Evidently a bad chip, though I have been using it for the past three years (P4 3.0ghz, 800fsb, HT).

So, because I really had a hard time finding an affordable chip for the 478 socket, I found a deal on newegg that gave me an AMD mobo and chip combo. So, I just got it and replaced it tonight. I hooked everything up correctly, and hooked the external parts up. Nothing on the screen happens, though all the lights and fans work fine.

I tested my monitor by hooking it into an old laptop, works perfectly.

I do not get a POST beep until I just have CPU, RAM, and IDE1 (CD / DVD drives) hooked in, yet still nothing on the screen when I turn it on (the new mobo has onboard video, I have tested with both my video card and this). The beep is just a regular one beep.
