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.

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?

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.

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

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?

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 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.

A:computer keeps turning off

I moved your post to a new thread, don't hijack other people's threads.

If your computer restarts during the installation it means you have an hardware issue.

Enter the BIOS at startup, locate the hardware monitor or pc health screen and report your temps, fan speeds and voltages.

Remove all the hardware that's not needed for the computer to start, leave only one memory stick, the system drive and the CD drive and see how far it goes.

What are your complete system specs ? Check the posting system specs link in my sig.

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

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.

If you feel confident momentarily short the 2 pins on the motherboard where the switch goes. Or alternatively, If the computer has a reset switch, plug the wires onto the pins for the On/Off switch and try starting with the reset switch.

Give this a try and report back to us.

Ya...I have an acer travelmate 290 (laptop) and it won't turn on. My brother, the genius he is , pressed a black nub on the corner of the computer (the one that puts it in sleep mode when you close/fold the laptop) and it went black and never started up again. When I press the on button, the cd device activates, the fan turns on for a few seconds then turns off. Nothing comes onto the screen. I've seen the troubleshooting book at the back, made sure the brightness is turned up and I even hooked it up to an external moniter but it was no use...I have no idea what happen or how to fix it...Plz Help!!!

The little button that you are refering to, is I expect the same as the one on the refrigerator that makes the light go out

I have one on my HP laptop as well. On my OLD laptop the button used to stick down occassionally, and I would have to tweak it to get it to pop up all the way.

Give that a try.

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?

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?

"Can it be the Psu still. Even if it worked with a jumpstart?"... In a word, yes

So I just spent 1400 dollars on parts and had my friend put it together for me since he's better with these kinds of things. It runs amazingly well, however randomly it will turn off and then right back on. All the parts are 100% new, so i'm finding it hard to believe it's the parts themselves.

The house I am in right now is rented since my house is being repaired from a fire, so it is possible it's the wiring in the house as well. From what I gather it could be just about anything though.. Would rather not have to spend a fortune having it repaired when I just spent 1400 dollars on it to begin with.

All help is appreciated! Thanks!

hey there... a few weeks ago i posted a question about my cpu that was not turning on. I went like a week ago to geek squad(rip-off) and they charge me like $70 just for telling me that they do not know what the problem is , anywayz, i gave my cpu to a friend and he checked for me, and he said that the problem is the hard drive. I changed the PSU because I though that the PSU was dead, and it was not that. I have no idea what it is. Could it be the hard drive? I don't think so.. any ideas guys?, thanks.

   Check the POWER settings -- your computer could be configured to automatically turn off the screen after 5 minutes of inactivity.  Change the setting to match your preferences.

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.

I have had my envy x360 for about a year and a half with no issue.  Last night it was running a little slow, most likely due to the programs running on it, but was working completely fine.  I had it on my lap, plugged in, and went to shift its position.  It immediately died, and could not be restarted.  The light next to the charger does not even turn on.  I have tried hard resetting it several times but no luck.  I'm a student and this laptop contains my life and ability to pass so please help.

I'm not sure whether this is a hardware or software problem so I thought I would post it here.

Basically at random times my computer just seems to lose power and shuts itself off. Ive have taken it too computer shops and had it looked at, they have done various things like change motherboard etc and none of that has helped. The last piece of advice I had was that it was probably software related and the best way to fix it would be to simply wipe the system and start from scratch but if possible id like to avoid that.

Sometimes the PC will stay on for 4/5/6hours at a time and run fine, other times after just 5 minutes it will shut itself off. Then when I try to turn it back on it won't switch on unless it is left for a while.

Does anyone have any idea what could be causing this?

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.

-Thanks

I would check the CPU temp in BIOS. Just switching off is usually due to overheat.

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
