My Computer Keeps Turning On and Off and Now It's Not Turning on

Q: My Computer Keeps Turning On and Off and Now It's Not Turning on

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.

Thanks,
G.

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.

My computer is HP with windows 7. I bought it in 2011.
This problem has been happening for a long time. Please help.

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.

If this doesn't fix the problem one of the Forum experts has prepared these troubleshooting guides with some additional suggestions.

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?

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.

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?

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 wou... Read more

When I turn on the power for the computer, the green light on the back lights up to indicate that there's power. But it wont turn on when I press the power button. I figured that something might've been wrong with the button so I took of the cover. The motherboard is a H-I41-uATX, here's a link for the specs and stuff: http://support.hp.com/us-en/document/c01903990I tried using the trick where you stick a screwdriver between some pins, but it didn't work. I did it on the pins in F_PANEL (You can see the motherboard layout in the support-link) I don't know if It's the wrong place, or if I'm putting it between the right pins, or the screwdriver is conductive, or if my power simply doesn't work.Please tell me if I should try again, if I'm doing someting wrong, or if I can try something else to fix this.I don't know if the battery (PS-5301-08HF) has died, but I don't see why it should, it all worked like 4 months ago.Also tell me if you need any pictures of the computer.Thanks in advance-Anton

My computer turns off by itself. I hate this problem so much. I'm not sure if this goes here but I have a Windows Vista so I thought it would. At first it would turn of once in a while. Now after an hour or so it goes off. It gets really annoying I don't even want to use it. Its fairly new - like 2 years. Can someone please explain whats going on and what I can do to solve it?

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.

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!) -
 
http://www.carrona.org/hwdiag.html
 
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 -
 
http://www.alcpu.com/coretemp
 
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?

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

Hello. I'm having a problem with my computer not turning on. It started when I moved my computer and plugged it back in. I've tried most things. Even jumpstarting the psu, which seemed to work by itself. I somehow got it to start randomly once and left it on until now. It worked pefectly fine once it actually started. Even beeped once, which indicated that nothing was wrong from what I read.
I tried changing the pins to use the reset button to start as well, but nothing. I also tried to unplug everything etc. Didn't start once.
But as I said, once I had tried all this I kinda tried every now and then to start it anyway, and one time it suddenly just started with one press.
Can it be the Psu still. Even if it worked with a jumpstart?

My left mouse button is not functioning correctly. The mouse itself is functioning correctly. The sensitivity, the right mouse button and the scroll wheel all work fine, but the left mouse button doesn't.
So I bought a HP Computer and I have had it for about a year now, with the mouse. The mouse is automatically connected to the computer wirelessly, but it doesn't require a USB slot (sorry, I don't know the specifics, I am very nooby when it comes to tech). Sometimes, when I play games, the mouse just stops working randomly, and I have to restart my computer by holding in the button.
My left mouse button recently has started to not function correctly. When I try to click on something, 1/4 times it will work. Most of the time I will have to click again or 3 times before it will click. I can, however, click the mouse button with an extra bit of force and it will work correctly, however, I am a gamer, and if I do this all the time, the mouse will probably break.
I don't know if this problem could have to do with my programs?
I have Windows 7, I run avast! (which I installed today, before my mouse started to not function correctly, however, it worked normally for about 8 hours after installing avast!)
I have gone to mouse preferences and tried to fix it there, but to no avail.

Any help would be appreciated, thank you!

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.

guys..ok well i jus replaced a cpu fan..to a better intel fan...and it comes up to my bios screen and i turn on the computer...then the cpu fan goes haywire and spins as fast as it can....then my computer automatically shuts down...

any clue??

i need a quick answer..cuz i got homework

A:computer turning on then off...

I've got two theories...

Either you installed the fan wrong... maybe you didn't use some thermal paste?...

or the fan is broken.


It sounds like your CPU is overheating... then trying to save itself it speeds up the fan (I assume you have some type of cool & quiet or other type of fan speed override enabled in the BIOS)... then as a last ditch effort, the PC is instantly shut off to save the CPU from becoming nothing more than a little brick of black chared metal.

I'd remove the "new" CPU fan... and make sure it's installed correctly... and if you didn't use any... make sure you put some thermal paste... and not too much. You should only use about the size of a pea of the stuff.... it's also possible that you put way too much paste on... in that case, remove some.

If you've already considered this and you've already ensured the fan is seated correctly on the CPU... did you buy the correct heatsink/fan combo for your processor type?

Not all fans are created equal...

also.... if your PC worked fine with the other fan, why did you replace 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.

Alrite i was reaching behind my tower to see plugs and all of a sudden i lost power to the cpu and now it wont start up. Randomly when i press the power button the computer fans spin once along with the mobo lighting up but turns right off again. It never fulls starts up. I posted it under hardware thinking it might be the psu, but im not sure. Any help would be great to get my comp running again

Open it up and check all your connections and cards to be sure they have not moved from their slots.

Be sure to run chkdsk /f to repair the damaged file system.

I just built a new computer today (specs are below), and now when I try to turn it on, the lights flash and the fans start and immediately stop spinning. Then, I have to turn it off and wait a few seconds before I can turn it on again. Can anyone tell me what could cause this sort of problem, and what to do to fix it?

Ok, ill explain. We do our thing on it then we go away (we dont turn anything off) we hit the enter button to bring back the blank screen ok, but nothing happens so i hit the button on the HUGE black box (sorry for my ignorance) in cubby hole at the bottom of the desk. Nothing happens. So i end up switching the whole lot off at the wall. The modem is all good and all lights are on. All plugs are in. My question is, why is it doing this. We have had computer (desktop) for about 5yrs. Im not computer literate so please speak in english. Hope someone can help. Cheers.

If this was new then I'd be looking at the power options, but download CPUID - System & hardware benchmark, monitoring, reporting which should show if it's an overheating problem and would you post a shot of its output.

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

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?

Hey guys,

For some reason my computer's just not turning on. The motherboard light is on, showing the PSU is working. But when I turn on the PC it just doesn't boot or even start at all.

Sorry for the vague description, just really unsure what the problem could be.

It might be your motherboard.

I need HELP! I have a computer and i think i have all compatable parts but it won't turn on. Yes it is plugged up. Please help me
 

A:Computer not turning on

little more information would be helpfull

Is this a new machine or older

Has it worked previously or is this the first boot.

By I think I have all compatible parts, what does this mean, have you done anything to the machine before the problem started.

If it's a new machine, please list the components you have installed, ie processor, motherboard, memory, add in cards, drives, etc.

If older, what os are you running, what does it do when you try to boot it.

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

Hello,

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?

Hey guys! Not sure if I'm in the right place to post this, if not please kindly redirect me.

So, I've recently purchased the parts to build a fairly top of the line gaming rig, have set it all up and had it running normally for about 3-4 days, now every now and again the computer won't turn on. It usually only happens on cold boots but has recently happened with restarting aswell.

The only way I can get the computer to turn on is if I turn the power supply off at the back, wait a few minutes and turn it back on (usually 50/50 chance that this works)

I have:
-updated bios to the latest version (0602) with no luck in fixing it.
-replaced the CMOS battery, aswell as reset the bios about 3-4 times now.
-checked the psu voltages, without any obvious problems (12.096v, 5.00v, 3.328v, aswell as Vol_CHAB=1.346v and Vol_CHCD=1.331v)
-I had previously had it overclocked via the ez tune wizard in the bios, with no negative side effects that I could find, so I redid the wizard on the last bios reset.
-have tried disconnecting the 4pin to the cpu as I read in one thread that if the 12v rails aren't identical that it could cause damage when the 8pin and 4 pin are plugged into the cpu socket on the mobo.

After I replaced the CMOS battery, it had about 5 cold boots working perfectly fine but then started faulting again.

I've ordered a 1kW psu to replace the 850w as I'm really hoping that its the problem, but I'm honestly not even sure anymore as ... Read more

BSOD issue originally appeared to be a hardware issue. It appears that was wrong.

I ran the Event viewer and I don't really know what it is telling me. I am concerned with the entry of Log:

I didn't even get out of bed until 10 am. Is there a virus or something trying to turn on my computer?

Any other info about the log would be helpful.

I bought all the parts to build a pc. I put the whole thing together and turned it on, but then it just started turning on and off. I unplugged everything except for the motherboard and processor and it is still in the on off cycle. I even cleared the cmos values to see if that would fix anything. What do I do now? Do I need to replace the motherboard now or is there something else I can do?

Specs:
evga supernova NEX750G power supply
Gigabyte Z170XP-SLI motherboard
Intel core i5 6500 processor
The light on the motherboard lights up. If everything is plugged in it all turns on but only for a few seconds and then it turns off again. And then back on again. And so on

A:Computer Keeps Turning Off

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.
