Computer won't turn on

Question: Computer won't turn on

My father's Dell won't turn on. They have tried different power cords and still no power. No lights turn on, nothing. It's like it's not plugged in. Any ideas?

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.

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

Hi, I have a problem with windows XP.

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.

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.

Here’s what I’ve done so far

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.

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.

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.

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.

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

Answer:Computer peripherals turn off but not computer itself?

Get into the motherboards bios by pressing a key noted when you first power up the computer. Look for "hit F? for setup" or something like that. Reset the bios to defaults

Time to start troubleshooting, and, given this may be very valuable info, you might want to take it to a shop.
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.

I'm assuming the problem is a cpu seating problem. I have already rmad this mobo for crooked led's and rma'd the cpu last week because of this same problem, so the problem may actually lie in the seating of the cpu itself. Right now I have the mobo on a piece of cardboard to make sure it's not grounding out. I'm using a 400watt DURO psu which I'm suspecting to be the problem now. What do you think? Remember only think installed on the mobo is the cpu and hs. NO memory or video card. I just want to see some fans moving. I get a jolt from teh fans, which I have read is just the normal ATX thing. When I short the power on jumpers I get a "TSS" sound and the fan jump. HELLLLPPP MEEE PLLEEEAASE!!!

Answer:New computer won't Turn on!AT ALL

This might sound crazy, but it's worked many times for me.

Unplug the Power Supply from all componants in your machine.
Press the ON button a couple of times.
Plug the power supply back in
Then turn on.

See if that fixes the problem

Next, change the power supply over.

I have had my IBM Aptiva since 2000 with Win98SE. Never ever let me down, although the OS has, more often than not. I never used the hybernation feature until recently. It didn't work that well, but still I used it for half a dozen times. Everytime It came out of hybernation it would power-up with the hybernation window on the desktop and then go back into hybernation. On second power-up it stayed up and worked as usual. BUT, two mornings ago it failed to turn-on. The two LEDs just flicker.

No HDD noise, no CPU fan, no PSU fan; nothing but the short flicker.

I diassembled the PSU, cleaned it and looked for fried items or burnt smell; nothing. Was unable to test voltages as I do not have dummy load. Internal fuse had integrity and managed to read +5V on two internal leads. As all failed, I reassembled the unit and had another go. The PSU fan worked and thinking all is well, reintalled it. BUT, same problem again. Computer won't turn-on.

Any help is very much appreciated. Thanks!

Answer:Computer won't turn-on

I'm not familiar with the IBM Aptiva, is it an atx psu?
If so, short the green wire to any black, that should power it up.

Hope that helps, Rik.

About last week, I was just browsing on the internet and suddenly the computer shut down unexpectedly. The computer restarted shortely after that, and about 5 seconds later, it shut down again. It kept on restarting and shutting down 5 seconds later.

After 3 hrs, it finally started up and I was able to go on the desktop screen. At first I thought it wasn't going to happen again, but suddenly, after an hour or so, the computer turned off without any warning!

Then it kept on restarting and shutting down after 5 seconds and kept on doing that. Sometimes it doesn't shut off after 5 seconds and manages to go to the desktop screen, but it always shuts down unexpectedly.

It's been happening over a week now, and today, my computer wouldn't start at all. I pressed the power button but it wouldn't do anything. When I unplug the power cord on the back of my computer and reconnect it, the computer turns on, but it shuts down after 5 seconds.

I read some articles about why this could be happening. I thought it was the heating problem so i opened up the computer and cleaned almost everything. I know it can't be a virus because I scanned the computer when I was able to use it for a short period of time. I don't know whats going on! Please help me!!!

Answer:Computer Won't Turn On!

Usually the first thing that I would check would be the power supply. If there is an led on the back of the computer, near where the power cord plugs in, let us know if it blinks rapidly when you try to turn on the computer.

I have an older computer that will not turn on. It tries too. I can flip the switch in the back and push the button on the front and sometimes the light will come on and the fan will turn but then it stops.

Thanks.

Well I got up this morning and my computer won't turn on at all. And I don't really know what to do. Yesterday it was having some problems and just restarting over and over.. Uh, so I decided I'd see if there's anything to do in this situation. Thanks for the answers.

Answer:Computer won't turn on..

Are the lights coming on at all? If not, my first guess would be the power supply. A failing power supply will reset your computer. There are a myriad of other issues it could be (motherboard for one), but that is the easist to test out. If you are fairly knowlegable, find a computer that is similar to yours and see if you can swap the power supply. Just be very careful to put all the right cables back, and don't force them into place.  Good luck!

Hello everyone!I have a very serious problem, and I need help:I have an (old) computer:Asus p4p800-VMRadeon 9200 se Creative Sound Blaster Audigy SE SB0570The mouse, keyboard and screen, are connected to the computer through a switch (Edimax).The computer had problems before, and tried to fix them. I saw that the connections from the front panel of the computer case to the motherboard were faulty. I rearranged the connections to the motherboard according to the board's original user guide, which I downloaded from the original ASUS website, they are now set well.Having done the connections (and there for also the case speaker, which was set faulty), I began to hear a series of beeps (six) form the BIOS every time I turned the computer on.The beeps were irregular and did not match any of the tables on manufactures site (not uniform and differently sounding beeps (.Other than the beeps, the computer worked great.One problem it did however had, was that it would not return from standby mode (Windows XP).

Answer:Computer won't turn on

if this computer had problems before, which you didn't specify, then it sounds like your power supply is dead, I know you said it looks like it's getting juice but it may only be enough to turn the led on and maybe have a small amount to something else. All your components use different voltages and there is one thing you can try and that is to replace the cmos battery that would be the coin battery on the motherboard that looks like a coin if this is faulty then you computer won't boot or it will be erratic at best. If that doesn't fix it then I would get a power supply you know is good and hook it to your computer and see if it powers up.  The standby issue is probably set in your BIOS you can change that if you can get it to turn on. Try the CMOS battery first you can pop it out and go to the store and match it with another fresh one after you install that try turning on the unit.............gettingthere

I have checked all the chords from the PS and they all look good, there is a green light on the motherboard that is always on unless I unplug the main power cable that runs from the PS the the MoBo. Its not throwing any error beeps or anything.

Answer:My computer will not turn on

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.

Hello everyone,

Well my name is Nick and I've got a problem and I hope this the correct section to post it.

I don't use any antivirus I just run malwarebytes once a week. I ran it a couple of days ago and it found a virus but said it couldn't delete it so I tried but was told I couldn't either because the file could not be read. So I ask some people what to do and someone recomended to run the malwarebytes in safe mode. So I tried but could not get into safe mode from start up so I googled it and found a way to open Run and type MSCONFIG and tell it to always open in safe mode. So I did and it prompted me to restart so I did and now my computer won't turn on. Everytime it tries it goes to a blue screen and turns off. Then it turns on and gives me a list of options and eveyone results in the blue screen and restarting. What can I do to fix

Sorry if this is hard to read but I had to type it on my iPod.

Answer:Can you help me turn my computer on?

It could be the virus or you may have some corruption on the HD. If it's the HD, boot the WinXP installation CD and at the first screen hit R for the recovery console. You may have to select which drive or partition your Windows installation is on. At the prompt type "chkdsk /r" without the quotation marks and hit enter. This will run an extensive test on the HD and make any necessary repairs. It could take a long time depending on how many problems it find and how big the HD is.

sounds like a short in the connection to either your walll or to the powersupply. could be a faulty powercable.. seems like the most logical thing, try using another cable to connect from your pc to the wall. if that doesnt work, its a problem with the PSU or wall outlet. you can test the outlet with another device to eliminate that.

Ok, so my problems all started a couple days ago when my internet connection kept going from "Network Cable Disconnected" to Now Connected status alot, every second sometimes. But then it started to randomly stop sending a video feed, and my monitor would go to power save mode. It seems whatever it is doing is not just affecting the video, because it also won't shut down, I have my computer set to shut down the computer when I press the power button, but when I press it it does nothing when it goes into this Blackout. The computer seems to be running, it's not making any weird sounds and the MB isn't beeping at me.

But now it won't even start up anymore, I'll turn it on and it will just immediately go black as mentioned above. I'm not sure if it's the motherboard failing, or maybe the Power Supply not supplying enough power to everything? I can't even get to the Bios screen anymore.

I should note that while trying to fix it before, I turned off the power supply while the computer was powered down, letting the light on the motherboard go off, then flipped it back on, and it worked fine for a while, but that doesn't work anymore.

Any ideas? My specs are in my sig.

Answer:Turn Computer on and.. Nothing

i would say you're correct in saying its either the psu or the board. if you can borrow a psu from a friend and see if their psu powers up your system. if it does then get a new psu, if not, i would say your board is shot.

i'm leaning more towards the board being shot though.

I return to my computer one day to find that it is turned off, i try to turn it on and nothing happens. There is a green light on the motherboard when the powercord is plugged in, i replaced the powersupply and the problem still persists. is tehre a way to fix this?

Answer:Help please, Computer will not turn on


Start checking for loose cords, lose wires, etc. Double check the 12 volt molex is plugged into the motherboard and make sure the heatsink fan is plugged into the motherboard.

Know way, it would really help if you would list your motherboard, CPU, video card, drives, power supply watts and brand name, etc....etc. You get the picture of what would help us.

Post back after you take a look in that case.

The computer is a Compaq Presario 5000. It has a Pentium 4 and windows XP installed on it. Im not any sort of computer-wiz but i do know a little about electronics. A couple months ago, my friend tried to install a wireless card into the tower. after that, she said the monitor wouldnt turn on. so i put off working on the computer for a while because i thought it was just a problem with the video card. well turns out there is more to this problem than i thought. for some reason, dont ask me why, she told me she had to take out the power supply. she dropped a screw in it. ohh man. and now, as soon as i plug the power supply into the wall, the computer tries to boot without me even pressing the on button. the hard drive lights blink as well as the power light on the front and also the cd drive blinks forever. the processor fan turns on as well as the power supply fan. the problem is, it doesnt sound like the hard drive is spinning at all and it sounds like the power is pulsing a bit.

sorry, i tried to describe the problem to the best of my knowledge so if you have any other questions just let me know. please help!

Answer:Computer Will Not Turn On! HELP!

a BIOS setting decides whether or not to automatically turn the system on when AC power is applied (it's a post-power failure setting).

I don't know how you drop a screw into a PSU... lol but you need to get it out so it doesn't cause a short circuit.

but anywho.. he's what you should do. You don't have to remove the mobo from the case (although that is the best way)...

1. unplug all power and data cables from the mobo and all other components
2. remove the CMOS battery and if equipped with one, set the CMOS jumper to clear
3. remove all RAM and PCI/video cards
---at this point there should be nothing but the CPU and HSF attached to the mobo---
4. blow out any dust from the RAM, PCI, and video card slots
5. re-install only 1 stick of RAM
6. re-install the video card (unless it's on-board video) and connect to monitor
7. hook up the boot hard drive (no other hard drives, floppy drives, or optical drives)
8. put the CMOS jumper back into it's normal position and re-install CMOS battery
9. plug the ATX power cable into the mobo (and the 4 pin CPU connector)
---at this point everything else should be un-installed or disconnected---
10. plug AC power cord in and attempt to boot up

...let us know what happens

I see there have been a couple posts like this, but thought I would personalize it.

To start, on my old comp I had problems with it turning back on when I turned it off. It would just come back on by itself.

Then one day it suddenly shut down, and would not turn on. When I tried to turn it on, it made a litle noise (would later discover it was the noise of fans turning on for a split second) but nothing else.

I figured it was old and I wanted to update anyway so I didnt care.

I went and bought a new motherboard, graphics card, processor, new RAM and a new power supply.

They were:

GIGABYTE GA-G33M-DS2R LGA 775 Intel G33 Micro ATX Intel Motherboard

APEVIA ATX-AS520W-BK ATX 520W Power Supply 115/230 V CB IEC 950/ TUV EN 60950/ UL 1950/ CSA 950

Intel Core 2 Duo E6700 Conroe 2.66GHz 4M shared L2 Cache LGA 775 Processor

GeForce 8800 GTX

And Kingston ValueRAM 2GB (2 x 1GB) 240-Pin DDR2 SDRAM DDR2 800 (PC2 6400) Dual Channel Kit Desktop Memory

I installed everything into my old case.

When I turned it on the processor fan spun, fan on the power supply spun, and fan on the side cover spun for a second, then shut off.

I switched outlets and when I turned it on again, suddenly the processor fan and power supply fan both turned on and stayed on. However, the processor made a high pitched continuous noise.

I turned it off. I noticed the fan was a little loose from the motherboard so I tightened it and turned it on again. Again it turned on... Read more

Answer:New computer will not turn on

Even tho' 520w PSU should be enough, it may not have the needed amps on the 12v rail(s) to fire up the mobo.... hopefully that's all it is. My other thought is that maybe the heat sink on the CPU wasn't seated correctly and the CPU may have been thermally damaged. I know it doesn't seem possible that a CPU can reach critical temps that fast, but a friend burned up on old Duron 800 by turning on the PC for about 3 seconds without a heatsink; "I was testing my RAM and just wanted to see if would POST and didn't think I needed the heat sink..." - famous last words Double check everything: the RAM, video card, CPU, all power connections and data cables. Be sure everything is seated firmly. Maybe take the mobo out of the case and see if it powers up "on the bench". Maybe something in the case is grounding it.

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.

Check your BIOS settings, which power management options. The feature you stated is desireable, for example for a kiosk so it would recover automatically when a power outage ocurred.

Hey everyone, kinda new to the forum but I was hoping someone could give me some help. I've looked everywhere for my specific issue, but I've only found one or two things which haven't been all too helpful...

Alright...this situation is sparratic at best...sometimes it boots past post, sometimes it won't POST at all.

I have:
KS8-LA motherboard (OEM from Compaq),
Athlon 64 3400+ processor.
2 512 sticks of DDR ram
Geforce 6800+ GT OC Video Card
Audigy 2 ZS Audio
2 cd drives (one DVD & one CDRW)
1 80gig Maxtor Hard Drive and the other is a SATA drive that I can't get to show up but it's plugged in so i can try to locate it.
2 120mm fans

When I boot up my computer it won't POST. My monitor stays in Standby mode but for some reason my CDRW drive light stays on but won't open.

Sometimes I can do the following and it'll allow the computer to come on. I've reset the CMOS both by jumper & cmos battery removal. pulled the power/IDE from all the drives. I've even done as some have said to unplug the computer, push the power button in and hold it for 30 sec to a min. Not sure what that does but it's helped once.

The weird thing is, I was working on it on my living room table. everything was working fine and I was installing drivers etc. I went to move it after the final driver was installed and it went back to doing what it was doing. I was extra careful and only moved it 3 feet tops. This is driving me ... Read more

ANY help would be appreciated greatly.

Basically my problem is that my computer will not even turn on. When I plug in the power supply and press ON it does not start up.

The motherboard make is an abit AV8. It has an LED on it and the numbers 02 (possibly 0.2) and 3 appear, one switching with the other at seemingly random, short intervals.

I have looked up in the manual what these numbers are and it says they are POST codes. However, these specific numbers do not appear in the manual's list of these codes.

Thanks in advance for any help at all.

Answer:my computer will not turn off by itself.

Either a program is refusing to close or you have a bad driver installed. If this has just started, might try using the restore feature in WIndows going back before the problem existed. If that doesn't fix it, what have you recently installed? What error messages are you getting when Windows starts or shuts down?

I'm wondering if there is someone that has patience here with someone who knows hardly anything at all about computers. I was trying to install my norton anti virus but it wasn't installing properly so I tried un-installing it and re-installing once again. I continued to do this about 5 times and in the end gave up and turned my computer off. When I tried to turn my computer on the next morning all I could get was the "set up utility menu" . Any help you can give would be so much appreciated.

Hi guys,

I recently purchased an assembled computer from simlim. It was working until recently where i pressed the power button and the computer wont boot. The LED light on the motherboard is on and the fan wont move.

Tried turning it off and on in 5 mins interval several times but couldnt work. Tried testing the power supply also.

Any suggestions?

The specs that i know :

Processor : Intel core i3 @3.2 ghz
Video Card : MSI R6850 Cyclone IGDS Power Edition
OS : Windows 7

Answer:Computer cant turn on

How did you test the power supply?

Did you ensure that all power connectors are properly connected?

This is an issue regarding the power supply or motherboard. Since there's no POST beep code (is there?) or anything of the like, there's no other explanation other than these two. You will probably want to RMA it since you just recently purchased it.

Answer:Computer won't turn on....

Well, that certaintly maens that something in the power department got tripped. Check all power connections, make sure power supply is switched on, ATX (assuming your board is ATX) power is in, etc. There shouldn't be any other reason why your computer doesn't turn on, if something else was bad, it'd make a big fuss about it with the harmonios tune of your PC speaker.

Just remember, i could be wrong.

No image on monitor. Power supply?

Hello, sorry to start another thread on this issue but I have had a browse through the others and found nothing that seems to help. I have also looked at some of the tutorials to no avail..

I'm fairly noob when it comes to this but I was doing my regular thing when my computer shut down randomly. It reebooted automatically and got to the asus screen where it shut down automatically again. It did this once more. After the third time it no longer rebooted (i.e. it shut down and stayed shut down).

I tried to turn it on, but nothing. I noticed the LED on the motherboard is still on, so hopefully my hardware is still good.

Are there any easy things I can try before switching PSU/Mobo etc? I've already tried different power cable and the unplug+hold power for 30 seconds+plug back trick. Still no good....

Answer:Computer will not turn on

It would be helpful if you gave us the brand and model of computer or motherboard.

The fact that there remains a lit LED on the motherboard means almost nothing.
The board can be totally worthless and still have that light on. It only requires 1/8 to 1/4 of a volt.

Last night I left my computer on when I left for work. When I came home, I found it turned off, I thought it was no biggie, maybe my dad turned it off. But when I pushed the power button to turn it back on, nothing happened. No lights turned on, no fans or anything. I then unplugged everything and opened up the case. I plugged the power supply back in, and tried powering agian. Agian nothing happened. The only light that was on was the standby powerlight on the motherboard.
My intitial reaction is that it's a power supply failure, or a power on switch failure. However looking through some other posts on similar problems says there is a chance it is a motherboard issue.
What can I do to narrow this down to a single problem.
