Computer does not turn on

Q: 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 http://downloadreimage.com/download.php. (This link will automatically start a download of Reimage that you can save to your computer.)

A: 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

A: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.

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.

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

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?
Thanks

Hi everyone,

While turning on my computer the it turns on, fans are starting to move, but screen won't turn on, and the beep of the bios is not heard.

pressing the sleep/reset button next to the turn-on button computer goes off, pressing it again turns on the computer without any problem. (now I'm working with the same computer) i thought maybe it's the power supply that gives me problem but changed between computers, this still gives me trouble and other computer works good (besides its many problems ). any idea what to do?

Thanks in advance

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.

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.

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!

A: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.

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.



   Information
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.



   Warning
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.

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.

A: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 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.
 

A: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?

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?

I have a second computer which has a 478 chip,video card etc. For a longtime I have noticed when I go to and run pcpitstop it says my video card is performing badly...56 pixel while the average is 124.

Recently it wouldn't start properly and my monitor would flicker and die so I changed the monitor but got the same problem.

I had already changed my power supply so I took it back and asked if they would check my video card.

They said they had found a problem with my motherboard and solved the problem.

Although it starts up ok initially, after about 15 minutes it blacks out .

However the thing is still going even when I try to turn it off with the switch.

If I hold the switch in, it does go off after about 15 seconds, but when I let it go it immediately starts again but nothing appears on the screen. Eventually I get it going again and it boots up perfectly only to crash again within 10 to 15 minutes.

1. Check the outlet at work. If it starts at home it should start at work. Maybe it cooled off by the time you got home.
2.This could be a power supply or a heat issue. Clean out any dust/dirt and get the PS tested.
3.If you don't have a backup plan, now is the time to get one and implement it.

Hello, My computer will not turn off. The only way it will shut down is if I Hibernate. In the last couple of days there is a blank window for add or remove programs. Hope you can help. Roy.

A:Cannot turn off computer

You could hold down the power button to turn it off but that's not a very good idea. Have you tried running a virus scan or something similar to that? AVG is free if you want to give that a go. There are some other good programs too like spybot SD and ad-aware that are also free. Those could help too if it's a virus or something.

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.

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.

System manufacturer and model?

You say it won't rurn on...but it's turned on if there is power to the system. Do you mean it won't boot into Windows?

Is there any evidence that the monitor is working properly?

Hi.
Every time i wanted to shut Off the computer i used to click "turn off" icon and it used to turn the computer Off, but the last few days when i click "turn off" the computer icon, it doesn't shuts off , but restarts the computer, so i have to shut it off manually.

I'm using Win.Xp, and my comp. is: AMD Athlon[TM]XP 2500+

Thanks All.
 

A:Can't turn Off the computer

Did you install any new hardware or software just prior to this happening?

A quick fix might be to try a System Restore to a date just prior to the problem.

Start > Run: msconfig > Launch System Restore and select a date before this was happening.

System Restores can be "undone" if not helpful.

Yesterday i tried installing a new video card (ati radeon 9550, to be exact) and after installation and hooking everything back up my computer wouldn't turn on. i figured it was my power supply, seeing how it was only 250 watts, so i went and bought a 400 watt power supply. so i hooked up the new power supply and it still won't turn on, i'm thinking it might be a problem with my motherboard or something.

pc specs:
hp pavilion a420n
AMD Athlon(T) XP 3000+ 2.167 GHz
512 ram
160 hdd 7200 rpm
crappy onboard video card (reasoning on bying a new video card)

if anybody has any suggestion on repairing my comp, please tell me. thanks.
 

A:Computer won't turn on

did you try the old video card again?

Earlier today after my wife had been gone for a little while she got back on her laptop to find it was double typing letters, she'd go to type r and it would respond with rt for example. While i was trying to fix that we ended up removing the battery on the bios screen due to it freezing up on us. Ever since then I have not been able to get it to turn back on. I've tried holding the power button for 30 seconds unplugged battery removed, windows plus b key and power key for 1 second, unplugging the cmos battery to no avail. Any ideas on what the problem could be? Its a HP pavilion g7 notebook with windows 8.

Hey guys, hope you're all doing alright tonight.
Here's what happened:

I had formatted my computer earlier today, and noticed that my copy of CoD: MW2 was lagging a lot. After determining that it wasn't a hardware/driver problem (it was running just fine in the morning), I decided to try formatting again. I left my computer unattended, and when I got back, it was off.

I checked all the connections, tried a different power cord, different plug, tried removing and putting back the RAM sticks; nothing. What happens is this: When I plug the computer in, the PSU indicator light at the back turns green, as it usually does. Once I press the power button, it (the power button LED) flashes and both the PSU and the power button lights turn off. I have no idea what might've caused this without a single warning. Can anyone please help?

Thanks in advance.

Specs:
AMD AthlonTM 64 X2 Dual-Core Processor 4600+ , 2.4GHz
3Gb DDR2 RAM
nVidia GeForce 8600GT
320Gb Hard Drive
X-Studio 5.1 Sound card (installed about a week ago)
Windows 7 32-bit

Other than the GPU and the sound card and 1Gb of added RAM, everything is default: HP a1730n

If you checked all the connections and are good i would suspect the power supply.

Hello everyone,

I have a 5 year old machine, a gateway, with an Intel Pentium 4 - 3GHz. Windows XP Pro SP3.

Here's the problem: A few days ago, I noticed that my computer was off, when I thought I had put it on "stand by", but then it started normally when I pushed the button. This happened a few times, then I noticed the clock was off by an hour. And then it wouldn't turn on at all, I checked that it was getting power, and it was, I plugged it back in, pressed the button and it booted up normally.

OK so I thought the battery was on its last leg, so I replaced it. I thought the problem was solved, but it isn't. With the box open, and the power on, I noticed a very high pitched sound maybe coming from the motherboard (I can't be sure). there is this green LED on the motherboard, and the only way to start the computer is to disconnect the power for a few seconds (until the green LED goes off) and then reconnect the power and push the button.

So I wonder if I should replace the motherboard or the power supply. I ran a benchmark with the CPU at 100% for ten minutes and everything stayed cool (thanks to the 13.5 Cm. cooling fan) and the voltages stayed normal, so I don't think its the power supply.

Is there any other way to diagnose this problem? I know the power supply is usually the first suspect, but the on/off switch goes to the motherboard, so it controls the PSU.

Thanks in advance for your advice.
Aloha

power supply even when it keep voltage. change battery on motherboard the clock after replacing should stay at all time. Why power supply?? tell me the brand. check brand and google feedback about it propably is the cheapest one

Hey. So it looks like I'm back with a more serious issue this time.

I moved over the weekend and transported my PC with me. I went to plug it in today and the PC won't turn on. The monitor is fine and the LCD light on the front of the PC is glowing when it's plugged in, but when I click the button, nothing happens.

I have an E-machine model T2896. It's about 4 years old, I believe. I didn't have any problems with the computer prior to the move. All components are the original.

I took the computer apart and looked at it. Came to the conclusion that it had to be a power source issure or a switch problem. Bought a new power source- no dice. Then I tried tricking the switch into believing it was being pushed, by wiring the two wires together. It's still not working.

Both my dad and I are at a loss. We have no idea what it could be. We tried reseating everything. That didn't work either. Any ideas?

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.
 

A: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 additions to the quote....

I will caboose on to the end of this thread. I left the laptop unplugged with the battery out, which is shot anyway, for probably three months. Now at start up it beeps three times and that's all. Blank screen, fan runs. Tried to boot from a OS cd but the optical drive doesn't start. Ideas, other than chewing my hind end for leaving it unplugged....

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.
 

A: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 All - I'm hoping this is something I can do myself, but my desktop computer won't turn on. After pressing the power button I here a quiet high pitched squeal leaving me to believe that the power source is bad and the fan doesn't spin

Can you please let me know what my first step would be to try and get the pc back up and running.

Thanks in advance for any and all help.

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.

Hellow guys, i'm also currently have an issues where, when i switch on the main switch, the computer turn on itself, i didnt even press the power button! And after a few second, maybe 2 to 3 or 4, it turn off itself again. When i press the power button myself, there is no more power. I cant turn it on.

So, i do the same thing again. This time I switch off the main switch and turn it back on and the same thing happen again, the computer turn on and off again, and i also cannot switch on the computer after that. The same thing happen the next few time, so i assume there is something wrong with the hardware, or something loose? Any idea anyone?

And, to be more specific, when i turn off the main switch and turn on immediatly, there is no power and the computer is not running. But if i wait for maybe a few minute after turn off the main switch and turn back on, it run itself, the same process as i mention above. So is it weird? Hardware problem?

A:Computer turn on and off itself? Help

did it just start doing this out of the blue? Did you do something before this started?

The first thing I'd check is the power button on the case, as you say it does not work and if it's jammed on the ON it could give similar issues.
Open the case and remove the power button connector from the motherboard's pins, and if you can install in its place the connector of the reset button. Both buttons are the same under the hood so it's not going to hurt the board.
Now try using the reset button as if it was the power on/off button.
