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.)

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.

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.

Startup 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?

Can anyone help with what might be going 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.

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.

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).

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??

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.

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.

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

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.

I have a windows vista packard bell iMedia x2416 with no modifications which is not turning on. The fan goes for about 2 seconds and the harddrive ticks as if it is going to turn on and then it just stops. I had an issue a few days ago where it said there was an error with start up but I followed the instructions and it start fine afterwards. Any ideas to what it could be? I'm hoping its not the harddrive but I have a terrible feeling it is. Any help on the topic would be really appriciated as I have backed up all of my stuff but my parents haven't!

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.

here are my system specs:
3.2 Ghz hyperthreading processor
1 GB of ram
120 GB HDD

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!

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.

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.

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.

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.

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.

Any ideas?

My computer turns off, a while after it is turned on.

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?

I have a Pentium 4 1500 gateway. I turn on the computer and it starts to load.
I see the Windows screen then the computer just shuts down and restarts again.
It has done this around 40 times now in 4 days and just wont turn on.
Is this some kind of short somewhere in the computer.
I also disconnected it from the power source and tried a new one and still the same thing.
Can anyone give me advice what it could be>

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.

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?


Work Machine Specs:

Phenom II 965 BE
ASUS M4A79XTD EVO motherboard
1 x WD 500 GB drive
Sapphire Radeon HD6450 vid card
Logitech KB and mouse
Generic 450W PSU

A:MSE keeps turning off while using the computer

Does your work use another corporate anti-virus product by any chance?

If you upload the eventviewer log, I'll have a look if you like.

Dell Studio XPS 435 MT, 3 yrs. old, intel i7 CPU, 64 bit operating system, 4GB ram, but when you right-click computer, properties, it says 3GB ram. I have been having this problem for a month. We leave the computer on at night half the time and half the time turn it off. One morning it would not turn on, only had an amber blink when you pushed the power button. My warrenty from Dell is expired but I did get some tech support, and at one point got the pc on, which gave me a CMOS message, Dell told me I needed to call the Geek Squad, which I cannot afford at this time so I got onto this forum and read alot of posts by many user's and the end result was I bought a new CR2032 battery and installed it. Everything is good, pc powers up as it should, clock issue fixed. Let me just say, the only change to this computer, and it was around the time this issue started, was that I updated the graphics card, for an online MMORPG game that I play. The graphics driver is and ATI Radeon HD4350, I went to the AMD site and updated. RAM issue I just noticed before starting this post is that pc says 3.00gb ram, my invoice says 4.00, and I'm sure the computer has said 4.00 previously.
On to the issue!! After replacing the battery things worked fine. I like to leave the pc on at night, last week in the am I came to the computer and it was on but totally unresponsive, black screen, mouse movement and enter key made no difference. I held the power button down turned it off and of course it... Read more

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 ^_^

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.
