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.

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.
Norton says no viruses.
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?

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.


please anyone....it's my moms monitor and she's gonna kill me, i blew it up.

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

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.

Heres the deal, i recently completed building another computer, but when i push the power button.. nothing happens, i've tested it out with a working button, nothing! The power supply works, in fact, when i turn on the power supply, the light on the motherboard lights up. Everything is plugged in, jumpers in their rightful places, everything is compatible. I have never had this happen before, well i have, but its always been something stupid i forgot to do. the system specs are: 600w PSU, ASUS p5nd2-sli (i've read the user guide front in back, nothing in there was helpful) Pentium D 830, 256 mb DDR2, dvdrw drive, 500gig SATA seagate barrucuda, geforce 7300 gs. the system isnt complete, i still need to get ram and a video card and an os, but i had some spare parts laying around and i wanted to test it all out, and install the drivers

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.

Recently my computer has been reluctant(!) to be active. When i connect my power cable to the outlet,the green light on my monitor beeps.But when I press the power button of the CPU then nothing happens i.e. the fans doesnt rotate or no images are viewed on the monitor.It looks like the motherboard isnt getting any power at all,but I believe my PSU is fine(the beeping of monitor lights as I said before) ,it looks to me that only the monitor is getting power,but motherboard doesnt. What should I do in this concern??

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? I'm not really that good when it comes to computers. thanks all!

A:Computer keeps turning off by itself

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.

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?

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

and ofcourse the cpu
u might want to reset the heatsink/fan incl' thermal paste

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.

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.

Lately when I turn on our computer it is taking forever for the desktop to appear. It shows the Windows XP background(the grass and blue sky) and after awhile the icons appear and the background is nothing. Is there something I can do to fix this?

A:Turning on Computer

You can check to see what programs are loading at Start Up by using the msconfig command in your run prompt (click Start, click Run, type msconfig in the Open box, and then click OK)

Try disabling some of the unecessary program to see if that will speed things up. Also remove any useless programs from the startup folder in the start menu. I would also look at what unecessary services are being started automatically by Windows (go to control panel>administrative tools>services) and disable any services that do not need to be started automatically.
You may also want to try a defrag on your system and check for any viruses and malware/spyware. Are you up to date with your anti-virus programs?

Today I got to my computer and it was completely dead. So I switched out the power supply with another computer. The power supply didn't work in that one either so I just figured it was dead. I put it back in and now the computer works fine. Any idea on what would cause it to not work for a 12 hour span? Sometimes the computer will randomly turn off, but only in the middle of the night if I have accidentally left it on and only every once in awhile. What would cause this?

A:Computer not turning on sometimes

Maybe the PSU is dying. Nothing else would usually cause this. You could try replacing your motherboard battery, though I don't think that's the issue.

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!

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.

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

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.

Hi, the other day i was just browsing the internet on my PC, and all of a sudden one of my fans started going crazy and it eventually started to slow down and stop. Iv taken my PC apart and discovered it is a fan on a nVidia heat sink attached to the motherboard. This heat sink has a metal rod that goes to the graphics cards of mine which are bridged 9800 GTs.

Can anybody identify this component so i can replace it/get a new fan for it if possible? Iv never seen one before, not brilliant with computers these days...

Thanks in advance for any help, heres the picture

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:

'System' Date/Time: 29/08/2011 6:16:47 AM.

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.

Hey all. I've run into apoblem with my computer. For some reason, it is not turning on. It wasworking fine yesterday but now it won't turn on. I've tried turning it on every now and then but with no luck. My computer is an eMachines,about 3 or 4 years old. Is there any solution to this other than hoping it will just turn on again sometime? Any help is much appreciated. Thanks.

A:Help! Computer is not turning on!

Warm welcome to the forum, paradox.

Have you checked the cabling at the rear of the computer?

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.
