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.

Hi!
I have this issue that when I turn on my computer, the power LED does not turn on but you can hear the fans working properly. I don't the issue and I'm not much of an expert with computers. Please help me solve this issue because I'm completely clueless.
 

Answer:Try to turn on my computer but only the fans work and the power led does not turn on

How old is the computer, what was the last change you made to the computer and when you last shut it down did it shut down correctly?

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. Everytime I turn off my computer by clicking on "turn off computer," I receive an error message popup that states "Windows Explorer has encountered a problem and needs to be closed." After that pop-up message, the computer freezes for about a minute and goes back to its normal format (desktop) and the computer DOES NOT TURN OFF.

How do I turn off my computer without unplugging the computer? I try "ctrl+alt+del" to go to the windows task manager to "shut down" the computer but..the computer restarts again and doesnt turn off. Do I have a virus or a windows explorer problem? and how do i fix it? thank you

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.

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.

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.

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.

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.

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

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?

I just got this HP pavilion 762n last year. Now whenever I turn the computer on it won't respond(Goes to a Blank Black Screen) and the only way I can make the computer respond is to go to safe mode and UN-install the Graphic Card, then restart the computer back again. Once I've done that the computer would work, but I can't watch Videos or play Video Games on the computer. There also would be these little blue lines on the computer screen (Sometimes their would be alot of the lines and sometimes the lines would be made by the trail of my mouse).

- Un-installing and re-installing my graphic card (Nvidia Geforce4 MX420 graphics card with TV-Out) that came with the computer.

- Rolling Back My Graphic Card.

- Updating My Drive from Windows Update.

- I've tried using a program that test my computer and tells me whats wrong with it. It said I got a problem with something like the VIDEO MEMORY CARD and I don't know what that is.

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

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

So when I got home from work the other day my computer was turned off. (it is always on) I went to turn it back on and it will not turn on. Well it turns on in the sense that the lights come on and the fan in the back starts up but that only lasts for about 3 seconds then it shuts off again. After that it just keeps trying to start up but it's the same thing only for about 3 seconds. Does anyone know what the cause of this might be?

I had somebody that was going to upgrade my desktop for me, deal fell thur, but he had already taken the RAM cards out. I put them back in, but when I turn on the computer nothing happens but the fans turn on and the yellow light flashes and the dvd drives cycle thru, but nothing else. I can turn it off and on but it refuses to boot up

Answer:when i turn my computer on

Pull the RAM sticks out and then power on.If you get beeps, that's good. That means your motherboard/bios is working and has detected the missing RAM.If you plug in the RAM and do not get a display, and do not get any beeps, the motherboard/bios is not working. One of the RAM sticks is bad, or you are not inserting them correctly and it's stopping the motherboard from operating..The three most important things in computing:1. Backups, 2. Backups and 3.

Hi

I have a p5ke-wifi motherboard and a thermaltake 600watt power supply

what has happened:

I installed a 2nd 1tb harddrive into my computer plugged the fan back in. i put the harddrive case back into the computer, tryed turning it on and nothing, i noticed that i jammed the (red) fan wire which exposed the wire. i pulled out the harddrive case tapped up the wire and it turned on. i switched off the computer and put the harddrive case back in without jamming the fan wire again, went to turn it on and nothing. any ideas? there is still a green light showing on my motherboard. have i surged my power supply?

Okay, so this is a little embarrassing, but my desktop won't turn on. It was working fine yesterday, so I opened up the side panel and after blowing out a little dust, making sure things were connected, I tried again. It looks like the power source is working just fine as there's a light on it when it's plugged in, so I don't think it's the problem.

I don't know what else it could be. Any help would be appreciated!

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).


Can anyone suggest what possibly could be wrong? is there a chance that the mobo or cpu is dead? but why would they just die for no reason, i mean if it always has been working really well and i have never touched the... Read more

Answer:Computer won't turn on, HELP!!!!!!!

Never heard of Skyhawk, which means it's GARBAGE. Yes, 9 chances out of 10, it is your PSU, and I would replace it as soon as possible, because it can (if it hasn't already) fry your other parts.

Get a quality brand name PSU.

In a nutshell, my desktop computer won't turn on anymore.

This is a system that I have built. It has been working with the current CPU and Motherboard for over a year. The last hardware upgrade I made was a new power supply and an extra stick of RAM, but it's been working fine with those things for a few months.

Last week, I when I was trying to plug something else in near my desk I somehow pulled on the other cords and my system all went off. I pushed all the plugs back in, and everything else powered on - speakers, monitor, etc. but not the computer. I wiggled the cables, unplugged them and plugged them back in, all that stuff, and it still won't come on.

I don't think it's the power supply because I noticed that when I flip the power supply's switch to "on" my optical mouse lights up.

I'm just not sure what else I can try or how to test what else it might be. Any suggestions would be helpful. thanks!

Sometimes when powering down for the day, after selecting turn off Computer, nothing happens. The screen doesn't freeze but the computer doesn't turn off. I've checked applications with CtlAltDel but nothing is running. I've even tried restart computer but still nothing. The only option is to manually switch off using the power switch. This doesn't happen daily but can be a couple times a week.Will it hurt the system if the PC doesn't power itself down? Any info appreciated. Thank you.

Answer:Can't turn off computer

click here See my post at the bottom of the page. That's what can sometimes happen if the power is cut suddenly before the hard-disks have parked the heads and powered down. Try configuring the power button action to initiate a shutdown if it is not already set like this. You'll know if it isn't because you'll probably have to hold the button in and then the power cuts off.R-click anywhere on the desktop, select properties, screensaver, power and advanced.

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?

I was using my PC a couple of days ago when it suddenly turned off out of nowhere! When I tried to reboot it wouldn't switch on.My main suspicion is that my computer has been overheating for a long time. I have been meaning to get it fixed but kept putting it off. The CPU temp starts off OK, but then quickly rises to 50-60 degrees. I'm not sure what it's supposed to be, but I know it's not supposed to be that hot!I'm not really sure what caused it to overheat so much, as a couple of months ago it was fine. I haven't added any new hardware, but I have recieved a lot of errors and a massive system slowdown ever since I got the internet, which was about the time my system started overheating too.Is there any way I can find out what's causing my computer not to turn on? It could be a blown fuse, but I don't know how to check.Please let me know your advice.

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.

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 !

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

I know there will be alot of different possible answers but I figured I would at least post it up. I built my own computer a few years ago and it's been running great. I was having a heat issue at one point but I layed down some arctic silver and that fixed the problem.

Well two days ago my computer just started freezing randomly. I'd have to turn it off and back on only to have it freeze whenever it felt like again. (It could be 3 minutes in or 2 hours in).

I opened up the case and blew a bunch of dust out. Was hoping that it would fix this issue. It didn't.

I took the heatsink off the cpu and figured maybe I should clean off the CPU and heatsink and place new arctic silver onto it. Well when pulling off the heatsink the CPU was stuck to it and I bent two prongs. After swearing at myself I carefully straightened them out so they looked like all the others. After that I completly cleaned off the heatsink and top of the cpu. I place the arctic silver on, spread it out evenly and placed the CPU back on the motherboard. It fits back into it's spot nice and the little lever goes down to hold it in place. I attached the heatsink, closed up the case, re-attached all the cords, flipped the swith in the back of the computer, hit the power button..... and nothing! I checked to make sure everything was plugged in ok and everything seams to be in tip-top shape.

2. Welcome to Techspot, Fetter.

3. Sound like your power supply is shot. Please have the power supply tested to confirm that problem. If it does, here you go. Buy another one, it should cost you 20 to 40 bucks for generic one ( last 5 to 1 years ) or you will have to fork over 50 dollars for a quality one, such as enermax.

4. Like you explained, that you have a heat issues in the cpu area, i suggest you to go out and buy the dual fan power supply to eleminate the air circulation waste.

5. Did you bent your Pentium 4? Did you break off any pins? Can you please take it off and confirm that?

6. To make sure, your motherboard and power supply is on, you will need to refer to # 5 and # 3. Try # 3 first.

7. If you have to buy new pentium 4, the used pentium 4 should cost 15 to 70 dollars, no big deals. Make sure to check it up on tigerdirect.com

By the way, I can see the Pentium 4 3.0gHZ for 77 bucks. It is affordable. Plus, I don't think you have a HT compatible motherboard, since you haven't indicate what kind of board you are using. Please give us your motherboard information, so we can determine if you are able to run in HT.

Hello,
 
I have an Acer Extensa 4420. It's a really old computer, but it has been working up until about 2 months ago. I had put it away in storage due to not having a need for it anymore. (It was a bit slow.) Well, I went to turn it on one day, about two months ago, and it simply wouldn't. Now, this pattern does change. (I have the cord hooked to it to ensure that it is not the battery. The charging light comes on.) Sometimes the power button will turn green and then instantly blink back off. More often, though, the power light will turn on, the fans will start whirring, etc., and then it will shut back off. It will then turn back on, as if rebooting itself, and then shut off entirely. During, this process, the screen never turns on. There are times when pushing the power button will not turn the computer on at all.
 
The screen on the Acer is beaten up. It appears as if there is a nick in a small black cord on the right side of the computer that connects to the screen. I just replaced the screen about a year ago, though. I have also already tried to reseat the ram modules by popping them out and putting them back in. This did nothing. I then tried replacing the CMOS battery. This also caused no change. I did put electrical tape on the nick in the screen cord, but I don't know if that is even helping much at all.

I am posting on a laptop right now, but less than 4 hours ago I was on my computer. I took an hour nap and woke up and it was turned off. Usually it just turns itself to sleep mode and you hit the pwr button an it loads back up...

Well it didn't load back up it was off. There was an electricial smell so I unplugged it and checked around. The power supply felt very warm but other than that everything seemed fine.

It does not boot up at all. I press the power button and the fan lights blink for half a second, the side an top fans spin for half a second, an it turns off. No sounds or anything.

I tried pluggig it into a different outlet, same thing.

Please help why did this happen? My computer is cooled properly and the temps are always good to my knowledge

Answer:Computer won't turn on

What temps are you getting? I do not think this is heat issue.

Try turning off your PSU or pulling the plug, pressing the power button to release any charge. Put it back the way it was and press the power button.

If nothing works, disconnect and reconnect everything internally. Look for anything out of place, blown capacitors, charring on anything.

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.

I have a HP Pavilion a705w.  It has 512 mb ram, 40g hd, pentium celeron 2.0 ghz.  I tried connecting my laptop (new Acer Aspire) via USB.  A bubble came up that said usb power surge.  The computer locked up so i turned it off via the button on front of tower (ctrl alt del did not work).Now when I turn it on nothing comes on the monitor.  The fan comes on and the blue light on the power button comes on.  The lights on the keyboard do not come on and nothing on the screen.  I tried unconnecting everything except the power supply and the monitor and still nothing came on.This is a seperate and now far less important question but how do i connect my laptop to desktop?  I need to transfer about 20 gigs and i do not wish to try the usb again.If anyone has suggestion I would greatly appreciate them.

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. 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 just built a computer for my friend, and it won't turn on. When I hit the power button, the fans that are connected directly to the power supply turn on for a few seconds, than off for a few seconds, than back on for a few seconds and keeps repeating. nothing plugged into the mobo turns on. I have a new antec TruePower Trio 650Watt so i am pretty sure thats not the problem. It is a Gigabyte GA-965P-DS3 motherboard with a Core 2 Duo Extreme Proc. I also have a nvidia 8800GTS videocard, and 2 gigs of corsair memory.

Does anyone know why it isnt turning on correctly? any ideas would be greatly appreciated. thanks.

Answer:New Computer Won't Turn On

that's normal for the DS3 mobo when you first use it, it`ll continue to turn on and off its all in the manual . It should stop doing it the next time you boot.

I worried when it first happened too but it all works fine after awhile, I would also recommend turning off the fan controls because if you watch, it`ll stop and start and that just worried me too much so now it goes full speed.

I have a gateway 550 gr with windows xp.  recently it would boot up to the point where there is a single wight dot on the screen and i pressed f8 and started it in safe mode and then got it to start normally.  Now, i turn it on and it gets stuck on the gateway screen every time not allowing me to even press f8.  There is less than 5 free gb on the computer's hard drive which could be the problem.  Also I have an external hard drive attached and in the past it has caused problems but i don't want to remove it without using the safely remove hardware button.  Any ideas?

Answer:Computer won't turn on

I would whilst the pc is switched off remove the external drive and then see if the pc boots up properly...if it does then you know where the problems lies.

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.

Here's my system:

Albatron K8X800 MB
AMD Athlon 64 3200+ Processor
Geforce MX4000 8x AGP Video card
Powmax 400W power supply
Ultra 512mb DDR

I think those should be the only relevant parts. I assume this must be a power supply issue, or possibly RAM, but I'm poor so I don't want to just go buying parts, and don't have many extras to test with. Any suggestions?
 

Answer:Computer won't turn on at all

Ok, so a few weeks ago I tried turning on my computer and nothing happened. Someone told me it's probably the power supply, so I got a new 500W one, (had a crappy brand 450W before), but the problem still remains. When I connect the power supply to everything besides the hard drive the computer turns on ok, but when I connect the hard drive as well it won't turn on. (I know it's not a problem with the power supply, since thef ans move for a sec. when I try to turn on).
Anyone got any idea what might be the problem?

Question: Turn computer off.

Rather perplexed over here.  XPS8910 with a new M.2 drive installed with Windows 10 Home Edition.  If I select "shut down" or "sleep", the computer will shut down and then two seconds later it will start for a second and then go into either "shut down" or "sleep" as selected... I'm quite annoyed with this.  Is this a BIOS issue or is this a Windows issue?  What should I do to fix this?

First hello everyone. My problem is this. Just a few days ago I tried to turn on my computer and it seems like it tried to start up but went dead on me. I have taken the side panel off to get a better look at what was going on and here is what I notice. When plug in, there is a power light on the motherboard that is light up. When I press the on button, for a few seconds, the cpu fan, psu fan and case fan come on and then shuts down. Pressing the on button again will do nothing unless I shut the PSU off and turn it back on, press the on button once again and the fans come on for a short second. Nothing else happens, the hdd will not spool up.I have metered the power supply and there is 115 v going to it. Could anyone help me in trouble shooting this problem, thanks.Specs,The computer is about 6-7 yrs old.Intel 3.0ghz450 w power supplyWindows XP80 Gb hard drive1 Gb DDR2 ram

Answer:Computer won't turn on!

I am thinking age here - and possible failure of one or more PSU rails.I would wish to remove plugs on supply rails from their respective devices and see if all give feeds - looking for 3.3v, 5v, and 12v.  The mobo LED suggests I think 5v present but if something else is missing you possibly won't go beyond fans.Check this out first - seems you know how to use a meter, which helps.  If PSU is OK then maybe BIOS - wonder if BIOS battery has expired.

I recently bought a brand new case, and put my old computer into it. Everything seems to be connected right, and when I turned it on everything runs for a split second and turns off. Any suggestions? The motherboard is an ABIT AT7-MAX2. I believe the Power SW and Reset SW are the only ones neccessary, so I took out the LED's until I can figure this out. Both Power SW and Reset SW's were put in the way other friends has told us, but the same problem occurs. Any suggestions?

Thank you,
Ross

Hi,
recently, i had my PSU literally blown up.
i hooked it up, and it started i dunno, i guess blowing up is the best word to describe it.

So, afterwards, (it was a 650 Cooler Master PSU) i got a 250W PSU and plugged it in.
the light in the mobo turns on, the little green electricity indicator, but the computer wonīt turn on.
i press the power button a million times, but it wont turn on, no light will turn on, no fan will turn, no little electricity sounds... nothing.

So, what is it? i dont think my mobo or anything else on my pc was fried, so can it be that the new 250w PSU isnīt comptaible with my pc?

I have a Radeon HD4670 512 Vram, m2n4-SLI mobo, an athlon 64 x2 5200+, 2 HDīs 1 is 80 gb and one is 300 gb, and two 1gb ram sticks.

Thanks guys.

Well, the most obvious way to turn it off, is to sumply shut down the power supply or pull out the plug.
But of course, I'm assuming you want the deeper problem solved. Have you tried antivirus scans and antimalware scans?

"We have tried all the power tricks and still nothing"...

What exactly were the "power tricks" you tried? No lights and no fans at all? You can't "kill" a PC by using any keyboard sequence. You can corrupt a hard drive, but this "dead" system needs a new power supply first... after you check all on-off switches and power cord connections

Hello everyone. Ok, here is the deal.... Today a bad storm started rolling in, so I shut down my computer and unplugged the surge protector from the wall.

After running into town and back (approx 1.5 hours) I plugged everything back in, and my computer would not start. EVERYTHING else plugged into the surge protector powers on: speakers, monitor, router and hub, external HD, desk fan, everything except my computer powers on. The only thing that is on is a little green light on the motherboard.

I have tried the following:

Flipping the reset switch on the power strip

Flipping the power supply switch on and off

Reseading various hardware

Checked, rechecked, and rechecked any / all cables inside and outside of the computer

Unpluged the computer's power cable from the surge protector and plugged it directly into the wall.

Nothing is working.

Now, I did not unplug the ethernet cable from the computer, but if it had been hit by lightening, wouldn't the cable modem, hub, or heck even a TV have gotten fried?

The only things I can think of doing is A) Buying a new power supply, or B) a new motherboard. What do you guys think? Please help, this is just super frustrating....I have a two thousand dollar footrest.

So recently my computer would not turn on. So I automatically thought it was either my psu or my mobo. Since I was already going to buy another psu I just went for it and bought one. I installed it, and upon pressing the power button it fired up, I was happy.About 3 minutes later, after I was already on the internet, it shut down again. I pressed the power button to try to turn it on and nothing happened.So I tried changing sockets on the wall for some reason, and it worked. Computer came back up, I checked the bios for overheating but I was running at 34 degrees so I continued starting up, only to find the computer shut down upon window's startup.I tried plugging the cord into a different socket and every time it fires up again for only 2 seconds now. If I dont change the plug then nothing happens whatsoever.If I leave the computer alone for long enough, then I am able to use it for longer without it powering off, which I would believe would be linked to overheating but the temps are completely fine.Any Ideas?Please
