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.

Preferred Solution: Computer turning on, then not turning on

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.)

A: Computer turning on, then not turning on

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.

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...

Hi,
I built a computer a few months ago. It has been working fine until one morning I tried to turn it on and the lights ont the front (decorative not system lights) flicker on for a split second and then turns off, the case fans and graphics card fan also move for a split second then stop.
I then have to pull the plug out of the power supply then put it back in and the same thing happens again.
I have tried taking all the components out (and unplugging all wires). Nothing. I even removed the cpu cooler and cpu but still nothing. i have tried clearing the CMOS on the motherboard. I think the motherboard may be faulty.

Any othe ideas/questions

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.

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.

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?

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.

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

I ran the computer with half the casing missing, so i could see what's going on.
I felt everywhere for heat, and it turns out that the power supply is fine and it is in fact my graphics card (Geforce 7600) was extremely hot, but i'm not too sure if something else is causing the problem. I can't get into windows beacause it shuts off before i even have a chance, please help me, do i need to replace someparts or do i need a new hard drive?

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?

TK.

Hi, I have a brand new corsair psu 850 that i got for my birthday on July 17, 2010. Computer worked like a dream on Sat and sun. Monday it does not turn on. Fan briefly stutters then turns off nothing else appears to be running. HOweve the light on the motherboard indicates that it is receiving power and thinks it is turned on.
Please help. Any ideas?
 

A:Computer not turning on

It could be the power supply is defective. Corsair makes good power supplies and I use them myself but sometimes this can happen just like with any other component. Do you have access to another PSU you can substitute to test with?

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.

Hey, I did search this topic before i posted but there seems to be lots of variations of problems.

Anyway...

My computer as recently has been randomly turning itself off for no reason. At first this was once week but now every few hours. Once it turns itself off it won?t turn back on for at least 10 minutes.

I first thought it was the cpu temp but I checked it ands its 34'c and then check the graphics card temp which is also fine.

My friend advised to run virus scan which I do but every time its halfway through the computer turns off. Also I was importing a CD via iTunes and it also turned itself off.

All this really started happening after i replaced the graphics card so I could have 2 monitors running. All worked great until it started to turn of randomly.

I am running a pc with windows xp (Home edition - Service Pack 2)

Intel Pentium 4 CPU 3.20HHz, 512 RAM

Need some help, thanks way in advance

cheers

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 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.

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:

I recently decided to change the power supply of my prebuilt computer because it was making a lot of noise. I changed from an ATNG 800 watt power supply to an EVGA SuperNova 1000G3. When I press the power button nothing turns on. I tested the power supply to see if it was the problem. The fan of the power supply spun for a second then automatically turned off. Does this mean that the power supply is broken?

There is also a cable that I?m unsure of where to connect it to the power supply. The cable is connected to the front ports. Is this preventing the computer from powering on?
I included a picture of the cable and a few pictures of the inside of my computer. Did I plug anything incorrectly?

Case: Inwin 303
Motherboard: MSI X99A Raider
New power supply: EVGA SuperNova 1000G3

Any help would be greatly appreciated. Thank you guys!

Shortly after getting my motherboard and CPU replaced, my computer started shutting it's self off. It occurs mostly if I have been using it for a while, or if I leave it on for a while, but if after it shuts off, I turn it back on, and start using it again it will shut it's self off again, and it will happen more frequently until it rests for a few days. Do you think it is my motherboard or my power supply? I have a 533 MHz Celeron processor with 256 MB of RAM The fan was just replaced about a year ago.
Thanks for the help

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.

A:is my computer turning off?

it sounds like your computer is going into "sleep" mode instead of shutting off.

I would recomment just clicking start/shut down when ever you want to turn off the computer... its easier on the computer that way.

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.
