Computer turning on, then not turning on

Q: Computer turning on, then not turning on

Let me clarify. My brother brought his computer over for me to recable it. Simple process right? Not so much. Before I get into details, let me give you specs. Keep in mind since I did not build the system, I do not have all the information I usually would.

Windows Vista
4 GB of RAM (unknown brand)
Abit motherboard (unknown serial number)
AMD athlon 64 3.0 GHZ processor
4 250GB harddrives (In raid configuration to look like 2 hard drives @ 500GB each)
Antec 550 watt power supply
Nvidia Geforce 8600 GT Video card

Okay, so when I recabled everything and powered the system on, it would not boot at all. Everything was on and running, but the bios was not doing anything, and everything was at a standstill. Not knowing if the raid configuation and the motherboard had anything to do with it, I started swtiching the sata connections into different configurations based on what I think the individual would have done. In doing this I accidentally pulled a jumper from the motherboard. Setting it aside and not thinking it was important, I plugged everything back in and attempted to power on the computer.

This is where it gets interesting. Instead of even powering on like it did last time, it powered up for MAYBE one second before shutting off. Any other attempts to power it on were futile, and resulted in nothing.

After this, I replaced the jumper where it was supposed to go, and powered on the system again. The same thing happened. I want to think the power supply is toast, but I would like some ideas/advice on what others may think it will be before I go switching parts out and/or buying new parts for my brothers machine.

Thankfully, if I have to buy new parts, they should be inexpensive because the processor is fairly old.

Any help is appreciated. Thank you.

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.)

Make sure that you have the 24-pin main power connector and the 4-pin power connector both connected to the motherboard.

Here is the issue, when my computer goes to sleep after it's on for a while when I move the mouse to get the screen back up it shows the backround no icons or anything to click.
Same if I turn it off and turn it back on. I have to turn it off and on many times then go to safe mode and shut down then turn it on again for it to work. Just now I had to turn it on/off 4 times for it to show the icons and task bar. Usually it is left blank with nothing to click having no choice but to turn it off.

A:When turning off computer & turning it back on again screen is blank

Hello squirrels and welcome to Seven Forums.

I think I'd start out by trying to do a startup repair. It's been suggested that the startup repair be done 3 times (regardless of what the notifications say) and the computer rebooted after each repair.

Long story short, My computer suddenly shut off, And when i pressed the power button it would attempt to turn on then just fail and shut down completely[no signal to anything, only fans]
I cleaned out the pc and cleaned out the power supply, reassembled and it turned on as per normal. i used it for about 35 minutes, set it to sleep for an hour or two, turned it on, used it for about an hour and a half then it suddenly turned off again. When this happens it either powers on for 2 seconds then powers down, or it powers up all fans and mouse led but no signal to keyboard or screen whatsoever i assumed it was the power supply so i purchased a new one today and installed it, It turned on first try, i assumed it was fixed, i used it, set it to sleep as per normal and went to turn it on again and it turned on all fans but once again no power to anything else, just fans it seems. I tried everything[I have two sticks of ram so i switched them/used them singularly tried running without fans, Oddly it didn't beep even without video card or ram but nothing made a difference. I just borrowed a single 2gb stick of ram from a friend and it successfully powered on and I am using it normally.. But i just can't imagine the problem was just the ram and i expect it to power off again soon, Can anyone help?

My other half and son were using the computer yesterday, and then left it on to do some other things, upon returning to the laptop noticed that the power button was solid blue (should be flashing orange when in standby mode), with nothing on the screen, moved the mouse with nothing happening as well as CTRL+ALT+DELETE.

Powered computer down by holding the on/off button for 5 seconds, restarted but noticed that I could hear the DVD drive power up but that is where it stops/hangs, nothing comes on the screen. Have done this numerous times, as well as removing the battery and starting with just mains power on?

Can anyone help with what might be going on ??

Hi there, i have some issues with my monitor (awhhh).

It's working fine like 10-20-30 minutes and then it's turning off (for no reason) while the cumputer is running and the flash/button goes pink. I don't know what's this colour stands for. Blue is when the monitor is active, yellow is when the monitor is turn to sleep and when i shut down my computer, but PINK? What's that, anyone?

The monitor is turning OFF, not in a sleep mode or something.
I must remove the cable and push back in every 20 minutes. That's wrong.

Maybe it's the cabel, maybe something with drivers and stuff...i don't know.

Just few hours ago I was listening to songs on Napster. Then I played some online games. I had to reboot at one point since it was going slow on me.

For some reasons unknown, my computer turns off and tried to boot itself, but kept turning off and booted itself. Somehow it did that in a loop. I tried to wipe up some dirt from inside(it may not be completely wiped up). I even tried to rearrange the cables and such. Now, if I press the power button, it only shows the power indicator, but it won't boot. I'm just puttoping it to rest right now hoping that it would back up tomorrow when I turn it on.

I have Velocity Micro with Windows XP SP3 (update progression). Motherboard: ASUS. I posted this using my laptop. I appreciate any help or input.

hello !   is it bad if i never turn off a desk-top console, or even a laptop computer, if the equipment is not going to be used for several hours ?  is it bad for a computer if the computer is left in the "turned-on mode" forever, without being turned off, ever ?  i guess that it is necessary to define "bad for the computer".  does the computer wear out faster if it is not turned off and turned on regularly ?  thank you.

I have a Windows 7 x64 installation at work, and for some reason MSE keeps turning off, and I get a little popup telling me it is deactivated, and that I should turn it on. It happens most when I'm using my browser (Firefox), but I only visit specific websites that I have been using for years for work related functions.

Turning on MSE takes forever. I've run scans with both MSE and MalwareBytes and turned up nothing. I'm not certain what to look for in the event viewer, or in any of the logs to see why this is happening.

Does anyone have a suggestion as to how I could troubleshoot this problem?

Any idea as to why and how i can fix it?

A:Computer Keeps Turning Off

Hi Uncle Yang !

How many minutes remaining in the installation process when the computer turns off ?

First thing to check would be the hardware : enter the BIOS and check your temps, fan speeds and voltages. Report them here. See if your CPU and RAM are supported by your motherboard : check the memory QVL and BIOS release notes. Update the BIOS to the latest revision.

Tell us more about your system : brands and models of the motherboard, video card, hard drives, CD/DVD drives, PCI cards and RAM. Check the posting system specs link in my sig.

Use at least an XP SP2 CD to install, you can slipstream the latest service pack on your original SP1 or pre-SP1 CD :
Slipstream SP2
Slipstream SP3 (needs an XP SP1 or SP2 CD to start the slipstreaming process)

Unplug all devices that are not needed during the installation, leave only the system drive, CD drive, video card and one ram stick in the DIMM1 slot. Use a PS/2 keyboard and mouse. Unplug all other drives, pci cards and external devices. You can install them one at a time once Windows is installed.

dont know if this a virus or whats really going on with my comp, i will be on from 2 mins - 1 hr and it will just shut off into power saving mode.im wondering if anyone can give me any help or thoughts i have scanned a million timesThis could be many different problems. Lets start with so easy fixes to see if they work first. 1. Go to "Start>Control Panel>Power Options"2. Now under "Power Schemes" tab make it say "Always on" and also the "Settings for Always On power schemes area" Should all be set at "Never" click Apply and ok.3. If that doesn't work your computer may be overheating. Overheating is a major problem with computers turning off all of a sudden. If it is over heating try cleaning out the insides of your computer and also installing some better fans.

Hi. I have 3 computers at home - 2 laptops connected via Wi-Fi and 1 desktop connected via Ethernet. Last night randomly one of the laptops (windows 7) turned off by itself and I lost internet connection on the other laptop (MacBook Pro) at the same time but the internet was working fine on my desktop (windows 8).
At first I ignored it and thought it was coincidental but the windows 7 laptop wouldn't turn on that easily until after few minutes when I get internet back on my MacBook Pro. Then about 20 minutes later the same thing happens and it happens one more time later that night.
I restored my router (Arris model and has built in modem) to its original factory settings and then unplugged it. In the morning when I go to plug it back in, the desktop which is connected to it via Ethernet, suddenly turns on by itself which now makes this even more complicated.
What do you think is going on? Why would the MacBook Pro never shut off but the windows 7 laptop shuts off causing the MacBook Pro to lose internet connection? Also plugging the router into AC power causing the desktop to turn on by itself as well is something I've never dealt with before. I did many virus scans using Avast, Malwarebytes and SuperAntiSpyware on both windows 7 and 8 computers and nothing showed up. I have never messed with the BIOS or changed any settings on any computer or on the router but this problem is strange and I can't seem to understand what is going on.

So another problem with a computer not starting up. Basically I use this computer in my lab and when I left for christmas I shut the system down. When I returned about a week later and tried to turn it on the power would come on for about 2 sec and then shut down. It took about 5-6 tries for the system to boot up.

Two weeks later I move into a new lab and bring the computer in to set it up. Same problem occurs, where it will come on for 2 sec and then nothing. After 5-6 tries it gets into windows but I need to restart and when I do it just shuts down and will not come back on, same 2 sec power on.

So I proceed to open the case and clean out and dust in it and push down on the connections to make sure. Still nothing, so I take the heat sink off of the chip (Athlon 2800) and clean it off. I put it back on and now nothing will turn on, no 2 sec power up, nothing.

Figuring the power supply went (even though the green power light is still on the Asus A7n8X motherboard that is in the system) I buy a new Antec power supply and install it. Same issue, no power up what so ever and, but the green power light on the MOBO is lit.

So my question is does this sound like I killed the mobo/cpu? Since the loss of any powerup started after I took off then put back on the cpu heatsink/fan I am thinking something happened then. But there are no visible issues with the motherboard and the chip never was unseated, just the heat sink and fan.

Also I tried switching the power and reset button ... Read more

I checked my computer, and the green LED in the front was on but everything else had stopped inside. I tried to restart it with the switch in the back of the computer and the same thing happened; the green LED would light up, but nothing else would do anything (this includes the fans).

Sudden system shutdown is often related to excessive heat buildup. Be sure the laptop is elevated for air flow. Clean air vents with compressed air.

Hello I'm a little new to these forums but I have an annoying problem and I was hoping this place could help me come to a solution. I just bought new components from the store about a week ago now and what it does is that it will just turn off for no reason. I was told and have read that it could be from over heating my cpu usually idles at around 40C and the highest I seen it get was 61C. the other problem could be that I don't have a big enough power supply to handle my power but I don't think thats it. So if anyone could help me out with my problem that would be awesome thank you.

Hi.Why dosen't Windows shut down immediately instead of going through a prolonged rigmarole?

A:Turning Off Computer

It goes through a series of shutdown procedures and cleanup processes to avoid OS and registry corruption.
The more it has to do, the longer it takes to complete.
The actual speed windows spends on each task can be tweaked but a safer way to speed up shutdown is through the individual apps that may be causing an issue.
Does yours take longer then, say, 30 sec for example?

I have a Compaq (fairly old) that when you push the power button, it will turn on for about 1-2 seconds and then shuts back off. During the 1-2 seconds that the pc turns on, you can see the fans for the heat sink and for the power supply turn on. It looks like they both reach the peak of speed and then that is when the pc shuts off. If you keep pushing the power button none-stop, you can actually get the fan to stay at a steady speed (Probably not good for the pc but it may help solve the problem). I replaced the power supply, re-applied new thermal paste for the heat sink, and made sure everything is installed on the board correctly and firmly. Any ideas of what may be causing this? I do not have any tools to test the hardware. Thanks in advance.

Not a very fancy title, but I'm sure it gets the point across.

Recently, we've had a problem with our computer, in which it would continuously beep once start up. The monitor wouldn't do anything, but there would be whirring from the computer, and the power button would be lit up.

This problem was solved the first time, but we don't know how. We disconnected a few of the wires from the back, and put them back in. Simple and easily.

However, this problem came up again, so we tried once more. We disconnected the wires at the back, but that didn't work, so we unplugged/switched it off at the switch. This was done two times. The first time, the same beeping problem occurred when we turned it back on again. The second time, the power buton wouldn't respond when we pushed it.

We've had this problem with our computer a few times, all for different the reasons. The first time our computer was rendered useless was in a power failure. We weren't the ones who solved it, but from what we hear, nothing was actually wrong. The second time it happened, it just wouldn't turn on after a night. This lasted only an hour, or so. It just turned back on again.

This time, we're not sure. It's been like this for a day. I'm sorry if my description of my computer's model isn't helpful - after all, I couldn't run the scan which gave the information.

If possible, could I also get assistance with the beeping problem? That is... Read more

Can you describe the beep pattern? This may indicate which hardware is having problems.
Your specs indicate you have a Dell Inspiron 530. This one has a low quality 300W PSU, which is just too low for any system really and it's likely failed. Can you borrow a good quality PSU to test with?

I am having some problems with a computer switching itself off, it may be after 5 minutes or 5 hours there is no consistency in it. When it does switch off the power light on the fron of the case is on but all the fans are off and when you hold the case switch in for a few seconds the light does go out.
I have ran checks on the hard drive, motherboard and memory and all passed without a problem. I have changed the power supply thinking that may be the problem but still no improvement. I don't think its heat related because of the wide variation in times that it stays on and the hardware monitor in the BIOS is reporting a processor temp of 50 deg C.
I have checked for Adware and virus's and found nothing. I am thinking that it may be motherboard related but the check in Microsocope reported no problems, is it possible to use Microsope to differentiate between motherboard and processor faults?
Any suggestions would be gratefully received

Hi I recently upgraded my CPU to an Intel I7 7700 from a I5 6500, but now when I try to turn it on, it powers on for about 8 seconds and then turns off, then on again for about 8 seconds, then off and just repeats. The screen doesn't turn on either and the motherboard does support the CPU ( which is a gigabyte h110m-a). I don't think it's a overheating problem either because I have around 5 fans all around the case. Please help if anyone can.

Recently a computer in a different room was giving me problems. It kept turning off on me, usually within a minute after booting up... Sometimes I got to the desktop but then it would turn off.
So I put it in my room to work on it, and I thought I fixed it. I left it on for days in my room... no problems.
I put it back in the other room and within a minute it did it again.
I thought it was the power cable but I switched it with the one in my room and still the same problem. So I tried the surge protector, same problem. The power supply is fine, as I tested it earlier. I Plugged the surge protector in a different outlet, still the same problem. Also, everything plugged into the surge protector and everything plugged in, in the room works fine.
You think the problem exists in the circuitry in the room or might there be a computer problem?

Computer Specs for the computer are pretty outdated. Its an old custom built computer, for work purposes. Its around 6 years old. But as it worked in my room, I don't think it should be an issue.

Recently, my computers been turning it self off...and i can't seem to find why.
I originally thought the problem was 7zip...as it crashed everytime i was extracting stuff...the just a few minutes ago, it crashed while i was encoding something.

I don't seem to get a BSoD or anything, it just switches off.

The only other thing that seems to be the same time every time it crashes, is i'm talking to someone on msn whos on a phone...might just be coincidence.

I'm guessing the problem is it auto-shutting down when the cpu gets too hot, or something to that extent...though i have no idea how to fix that.

Hello guys!

I just joined up because my frustration has peaked beyond levels with which I am able to function logically. I custom built this computer about 6 months ago, did all the research, got some feedback, ordered the parts, and put it together. Well, it worked splendidly for about 3-4 months with little to no issue, certainly not with the hardware. Well, I moved from Wisconsin to Florida, and the tower took the trip with me, between car rides and a flight. It hasn't worked since I arrived in florida over 2 months ago. I did some trouble shooting, and I've replaced both the motherboard and the power supply... so far, it hasn't made a difference. And now with 120 dollars extra down the drain for no apparent change, I am prepared to break something. I could use a little help.

My computer specs are:

Asus A55BM-E Motherboard (new)
EVGA 600 B 600W Power Supply (new)
8 GB of Ram ( G-Skill Ripjaws)
AMD Athlon x4 CPU
Radeon HD4650 Graphics Card
All packed up in the HAF CoolerMaster 912 case.

I have tested the power supply with a paper clip as suggested, and I even did it after plugging in all of my fans and HDD/Disk Drive. All worked for the length of time that I had the paper clip in the slots until I tried plugging in the CPU outlet, at which point it would flash on, and then turn immediately off. When I plug the power supply into the motherboard, the power light comes on the motherboard, but the power button on the front of the desktop does not wor... Read more

1st thing to do is take the mobo out of the coolermaster case nad do a "out of case build"
put it on the mobo box
connect just the psu (24 pin & 4/8 pin power plugs)
one stick of memory
and ofcourse the cpu
u might want to reset the heatsink/fan incl' thermal paste
connect the monitor
touch the power on pins and see what happens

I posted this in the Ram and Power Supply section initially but was directed here. Will copy paste original thread and attach the perfmon+sysnative
Howdy all,
Specs First:
MOBO: MSI P67A Military Class II
CPU: AMD FX 4100 Quad Core
GPU: 2x Nvidia GTX 460 in Sli
OS: Win 7
RAM: 2x 4GB Gskill 1600
PSU: Corsair TX850w
System is ~5 years old
The Problem:
My computer has recently started suffering crashes. It seemed to be a power cut to me at first but now I am not so sure. It just happens every now and then, no reproducable trigger that I know of (except the memtest discussed below)
The computer just clicks off, black monitor, no power to the tower. It does not reset itself, but I can instantly power it back on if I hit the power button.  Unfortunately this also means no Crash Dump or Error Log, since the computer is just losing power in an instant.
I am running dual gpu's in sli so first I tried disabling one of them, then the other, then doing a clean install of new drivers in safe mode. The problem continues.
I ran combofix and malwarebites and did a scan just in case it was a virus (I doubted it was) but the system came back clean.
Next I tried running memtestx86 from a usb. The computer crashes within the first 10% of the test.
I have 2x 4GB DDR3 in my tower. Called Ram#1 and Ram#2 from here.
I removed Ram#2. Only Ram#1 in the tower. Ran Memtest again.
Failed within 10%. Black Screen No Powe... Read more

Hi Chameleon Jim & Welcome to the forums ^_^,
There are no dump files included in the list. The way you have described your problems, it is possible that we might be dealing with a hardware problem.
First of all, are you overclocking your system? If yes, then please revert back to STOCK Settings. Also, let me know in case you overclocked in the past because components tend to degrade faster when overclocked.
I also see that you have EVEREST from Lavalys installed on your system. Have you been doing Stress Testing?
Could you please run the below  free diagnostics (Thanks usasma!) -
While performing the above diagnostics, please make sure that you keep a report of the temperatures (I have a strong feeling that your system might be overheating because I have experienced things  with my laptop like you are experiencing now). I use the free software called CoreTemp to monitor the temperatures which you can download from the below link -
Also, while performing the Memtest, by any chance did you notice the Temperature field which is displayed? If yes, then what did it say?
Oh and yea, what is the wattage and age of the power supply installed in your system?
Let me know how it goes ^_^

hi, my computer is not turning on anymore
i woke up today to use it, but it didnt turn on anymore, but it worked yesterday
previously, sometimes my computer didnt turn on, so i turn the power supply off then turn it on again, and then the computer works

now, the computer doesnt turn at alll, except for making one beep noise and then shuts off. The motherboard is a A7N8X-E model.
could it be the PSU? or has my mobo fried up...?

A:Computer not turning on

Also, do you smell anything weird in your mobo? like frying metal or plastic?

Ok I will start with saying that I had a working computer and a newer empty tower with just a motherboard in it. I wanted to update my working computer so got a new power supply and video card and switched them out. When I tried to start it up it would not turn on but make a grinding like noise like a fan was trying to run but none that I could see were moving. I will also add that my hard drive is an ssd. Thinking one of the two new pieces were bad I put the old two back in but it continues to do the same thing. Thinking that I may have fried the motherboard I bought a processor for my other tower that just had the motherboard and moved the ram, older power supply, newer video card, and ssd over to that tower. The first time I tried to start it it done the same thing. The second time there was a pop but continued to do the same thing. I will also add there are no lights or beeping.

A "pop" is never good. Most likely, something just failed (ie: blew).

Hello guys. I tried upgrading my computer's RAM. When I did I tried opening my computer. It stars running for a few seconds and then shuts down. Then it starts up again and makes these beeping noises. The monitor was still blank and my tablet and keyboard indicates it not on. Can someone pinpoint the problem for me please? The beeps are long and they keep going.

My computer is a Dell Dimension 9150.

A:Computer is not turning on

Long continuous beeps: I suspect no memory, incompatible memory, bad memory or memory not inserted properly.

A:computer turning on but not then off


emachines 2230 about 5-7 years old

have you blown out the insides with compressed air to get rid of hair and dust?
blow out the power supply, cpu fan and any other fans.
this is probably a power supply problem, if you can get into your bios, post the temps and voltages listed.
emachines supplies do not usually last that long.

My computer isn't turning on, I've tried multiple power cables and different powerboards. How can I tell any signs of something breaking inside the computer (it's a desktop). What do I look for signs of?


A:Computer Not Turning On?

physical signs of damage are rare, occasionally youll see a blow capacitor or resistor, basically anything burnt and unhealthy looking is Bad!

but its not always the case, ifs of all id check your power supply. if you have a volt meter and or a degree of knowledge about electricity you could quickly determine if theres any life when you press the power button.

the power button is also a good place to start. unplug it and touch the 2 pins together with a screw driver.
if it turns on, its a simple fix, if it doesnt and you cant test your power supply, see if you can borrow one from a friend.
I have a super cheap ?10 jobbie from ebay that I use to test. I literally only plug in the essential cables and press the power button, if it turns on, I turn it off straight away and have my answer.

I have Windows XP on my computer. What is the worst case scenario if, when I want to turn the computer off, I would press the "on" button on the tower, instead of clicking Start, Turn Off Computer, Turn Off? Thank you. abx

A:Turning off the computer

The proper way to turn off the computer is to use the on screen buttons. Start, Turn off computer, ect. This will shut down windows correctly and any programs running. It only takes a few seconds.

My grandfather handed down to me a mother board and some other parts to a computer he couldnt get to turn on, the motherboard is brand new and its only about a year old.

i used the mother board with some parts from my custom built computer but it doesnt look like the computer will turn on. Nor does it show any signs of power. i tried replacing the power cord and eventually i tested the motherboard with another power supply. the one i use has a power switch on the back, but the one tested with has a green LED to show when the power supply is getting power. It was glowing green so its getting power, just not to the mother board.

Is there any other trouble shooting i can do? i really dont want to replace the mother board or test another mother board.:dead:
