PC not turning on.

Q: PC not turning on.

My sincere apogoly for (probably) posting this in the wrong section (if I did atleast).

I was playing a normal game of League of Legends a day or 4 ago with my friend on Skype, when suddenly my monitor's screen turned black saying there was no signal, my keyboard and mouse stopped giving light and there was no sound anymore either. My PC was still on (the light coming from my power button was still working), but I couldn't turn down my pc through the power button, so I forced it to shut down by pressing on the O button from the power supply. I pressed the button back to I, tried to turn my PC on again and nothing happend. There was literally no sign of life : The blue light that's supposed to come from my power button didn't work, I didn't hear any fan working, the PC does nothing at all. It's not making any beep sounds whatsoever.

So I was thinking of what the problem might have been. I thought it would've either been my motherboard that died on me or my power supply. I was testing if my power supply died by using a paper clip that was connected to the green and black wire. I did hear a boot sound but I didn't see any fan spin around. Is this a sign of a faulty power supply unit or could it still be my motherboard?

Computer specs :
RAM : Crucial Ballistix Tactical 2x 4GIG
Processor : Intel I5 4460 / 3.2 Ghz
Cooler : Gelid Tranquillo Rev. 2
Case : Cooler Master N300
HDD : Seagate Barracuda 1TB
Motherboard : MSI H81M-E35
Videocard : MSI R9 280 Gaming 3G Graphics Card
PSU : Seasonic S12II-Bronze 520W

Any help would be highly appreciated.

Kind regards,

Edit : I don't have a spare PSU unfortunately.

Preferred Solution: PC 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: PC not turning on.

Well the only way to really tell is by using a dedicated PSU tester or another PSU which is known to be in good working order.
You can remove your PSU and take it to the local pc repairman, chances are they might do the testing for free.
However keep your finger crossed, because sometimes when a PSU goes bad, it can take the mobo with it.

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.

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.

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?

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.

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

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.


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

Hi all,

I've had a similar issue like this before and I managed to fix it- so I thought. My computer RANDOMLY shuts off and sometimes restarts but most of the time just goes black screen and the tower power stays on. It never turns off completely.

I managed to get a new GPU and PSU (Brand new) to which the GPU fixed the issue. This was about 6 months ago. Now, the same issue is happening. Its mainly triggered during a game, where the screen will switch off whilst playing League of Legends (very low end game compared to most).

Since i replace the two MAIN culprits that most people tell me it could be, is there any ideas. I'm starting to think its the SSD im using which is 120 gb Crucial. It has the game loaded on it and im running the whole OS off it as well.

There's an attachment with details of my Specs.

I have recently purchased a new motherboard\cpu\ram & Hdd to upgrade my existing desktop computer. I have kept my exisiting PSU & AGP Card.

The system will bootup and allow start off the windows installtion but would then turn off after a few minutes. I then have to remove power cable and reconnect to get it to bootup again.

I can enter the BIOS setup without any pobs and it doesnt turn off whilst i in the BIOS setup but when i exit, instead of restarting the system goes off again. Sometimes i have to remove power cable for several minutes before reconnecting because if i reconnect straight away the machine will power on but the fan on the ATI X1950 Pro AGP card spins on full and there is no display on monitor. CPU fan and case fan also come on.

When i am able to boot into the windows setup the machine does POST but then goes off again around the same point of the windows installtion.

I have tried another AGP graphics card, memory modules but still have the same issue.

Does anyone have any suggestion on what the problem could be?

Hi all. Once again I got another problem (and again another story ).

It started about 4 weeks ago, I woke up and my other pc was on and making a bad noise, as I looked at it the HD light was flashing in sync with the sound . So I tried to turn it off by holding in the power button inÖ.nothing so I went to the wall and switch off the power to it. I turned it back on and the pc started up but its self , so I thought I would locate the noise as it was on. The noise was coming form the PSU so I thought that was dead.

I told some what had happened and they told me that where the HD light was going that the HD was dead. I check the master and slave in an external HD case and they both work.

The new PSU came today so I put it into the pc wired it all up and switch the main power and again the pc starts up by it self (without any bad sounds this time), I turn the monitor on and all what happens is the light flashes on then off and so on and nothing on the screen.

I donít know what it could be. Anyone got any ideas?

Ok, I was recently at Best Buy and they had the new Mac G5's on sale for about 2,500. It's got dual processors running at 2.0ghz each and has the capability to use 8Gigs of ram. Holy mother of god, I want one! But, the sad thing is, I hate Mac OS. I've grown up on Windows, and as much as I disllike Microcrap, I love WinXP. and I have recently learned that you can't run Windows on Mac hardware... why?

Anyway, is there currently a PC out that has near these stats for that price? I like the idea of having 2 processors and that much ram. Thanks!

This notebook was working fine, and I was replacing the screen hinges, but now it will not turn on (i've taken the screen fully off because thats another problem for another time). I know about the flashing lights and power indicators, but after I charged it for over 24 hours, there are no lights when the on button is pressed, not even the three flashing 'out of battery' lights. the only thing that lights up is the little light next to the charger input, so the notebook knows there is a charger in, and I believe it is giving out power, as the light next to the charger is on, and the power brick gets warm to the touch after a few hours (which leads me to believe it is giving out power) HELP!! please!!!

ok...so my girlfriend's computer, she has two. one is hers and the other is her moms. hers wouldnt turn on, turned out to be a bad psu. her mom's wont turn on, i think it may just be the power button. because it sticks, and just doesn't seem to work the way it should. but i asked if she ever spilled any liquids in there, and she said that her dog once pee'd on it...so yea, after washing my hands, i figured that would be the problem, but just in case, do you think any other thing would contribute to the power not working? everything is hooked up to the motherboard correctly, and the psu i believe is working normal. either way, i replaced the psu with the one from my computer, that i know works, and it still didn't work.

Hi, i just started building my own PC out of some parts my dad had given me, he says he tested and checked all of them and said they worked.

Im not getting any system power whatsoever, the red LED on the mobo lights up that indicates when a power supply is connected, but when i hit the power switch i just hear a click from the PSU and nothing happens. Would that be a bad PSU or could it be something else?

The PSU and CPU fan i just bought today brand new.

2 years old. Unit will not turn on. Totally dead. No lights at all. I have tried:- holding in the start button for 30 seconds and all times in between- Swapping chargers as I have two - both HP originals- I have removed all plug ins  (which was only a mouse transmitter)- I have left the unit recharging overnight direct into the mains (normally plugged into surge protector) but nothing.- the unit is sealed and I am reluctant to open it as I really don't know what I am doing. Further hints useful but actually my question is whether it is worth paying for someone to look at this or shall I ditch it? It is on a PC World lease and I have just discovered that this affords me no  protection at all -  buyer beware - so trying to get another 12 months out of it will help me immensely.

Why my PC suddenly turned off everytime I play videos on Youtube? Same with my broadband,the connection got disconnected? I currently use Google chrome browser and my operating system is window 7 1GB RAM.
Anyone of you who can help me solve my problem? Badly needed you help guyz.

A:turning off

Can you give a little more information? Do you receive any error messages? What do you mean your broadband got disconnected?

From the initial sound of it, if your computer is just shutting off with no error messages whenever you try to play videos, you may have an issue with your power supply. If your power supply is dying, whenever the computer requires more electricity than the PSU can deliver (such as when you're watching videos), then one of the things that can happen is that the computer will spontaneously shut down.

Okay, so I was getting into a game of League of Legends when my PC froze. I turned it off and on again, it got past the POST and then froze again. I turned it off and on again and this time it turns on for a couple of seconds before turning on again - repeatedly. No display or anything. I've tried removing the CMOS battery and putting it back, still nothing. I've had this PC for about 2 years now and haven't changed a thing except that I installed an SSD a few months ago.

I finally got round to putting all the bits of my new rig together yesterday. Heres my spec of what i built:

Asus A7V333 Mobo
AMD Athlon 2000+
256Mb Crucial DDR
3D Prophet II MX
300w Herolchi Electronic Co (hec) PSU (Brand New)

I got everything connected together and flicked on the PSU, but sadly, no air from back of fan? The single L.E.D that is on my mobo lit up, which gives me some hope, but the fan of the processor did not turn, and neither would the fan of the PSU?
Now ive tried all the obvious solutions, change Power Cable, plug in to a mains socket on its own, check, double-check, and triple check that PSU to mobo connection is correct. But hell if i know what could be the problem???? Apart from a faulty PSU that is :rolleyes: . Should the PSU fan work independant of connection to mobo? As it doesnt when i try it like that also?
Can you think of any suggestions that might help me get to the root of this? Some advice would be much appreciated...

Hi all! Hoping for some help with my laptop that decided to stop working! It was fine until yesterday when it suddenly went blank/lost all power. I restarted and it went fine the rest of the evening.  Checked it again this evening, it worked for an hour, then it shut down again, but now won't switch on.  It sits absolutely dead, except when I follow this pattern. I remove the power lead, then remove the battery, wait a few seconds then reconnect the battery. Now the flashing battery light is on. I reconnect the power lead, the light for it shows but very faintly. I then push the power or novo buttons, the laptop will start up but then immediately shut down again, less than 1/2 seconds later. If I press the power button again nothing happens, it's dead as a door nail!  There is no noise from the fan, it's clean and not overheated. I'm stumped,  does anybody have any suggestions?

Hi Bucketybuck , 
Welcome to the Community Forums.
How about if you remove the battery , unplug the charger , remove the harddrive , remove the RAM  then press down the power button for 12 seconds to power drain.
Check if the ac adapter is working ( or if you have a spare ac charger to test) .
Plug in the charger ( battery , ram and harddrive still outside) . Turn it on . How is the power LED ? It suppose to beep without the memory but should indicate power or activity.  If it does beep , then try to isolate RAM individually on the slot. 
Update us how it goes .

A:Pc Keeps Turning Of! Can You Help?

There can be several causes to this, but it sounds like it is heat related and that you were on the right track with trying to remove dust. I would want to be SURE that all the dust is out of this computer, all fans are operating, and air is free to move in, out, and around this computer. Sometimes that is all it takes. But if you have already done all of that in a thorough way and you still have the shutting down issue, then perhaps we should look elsewhere for the source of the problem.

I would strongly recommend using a can of compressed air that you can buy at any computer or office supply store, not the hair dryer.

Let us know.

Hello yyyyyy, It would be helpful to know the model of your system and the version of the operating system. This faulty condition could be caused by several different reasons. I would first make sure the system is clean. HP systems seem to get dirty very easily. You might remove the side panel and see if the system has a dirt/dust buildup inside the case. If it does, I would clean all the dust/dirt from the system, paying close attention to the processor heatsink/fan, and also the power supply. You might need to acquire some compressed air to blow the heatsink/fan assemble free of any dust/dirt. This compressed air can usually be found at any computer shop and other stores. Please keep us updated.

Hi, please help if possible, my computer turns itself off at irregular intervals. This can be anything from immediately to 4 hours plus.

I then can’t turn it on again until I have unplugged the power cable for a few seconds and then I can turn on the PC as normal. This is what usually happens but sometimes it differs slightly ( see below ). I built the system about a year ago with all new parts and it has worked mostly ok until about 3 weeks ago. When it goes dead the power LED on the case still stays on.

So far I have tried the following...

1)Checked that all the fans are working.... Pass
2)Checked CPU and MB temps which are about 28 C and 30 C.... Hopefully OK
3)Tried plugging into new socket with working power cable..... No change
4)Updated any drivers..... No Change
5)Checked for hardware conflicts..... Pass
6)Checked power management in Bios and Windows..... Seems OK
7)Run virus scan.... Pass

What I have noticed so far. I don’t know how relevant these points are but they may help.

1)This has happened four times, when I go to turn on the computer nothing happens, no power seems to get through and no case LED’s are on. I have to unplu... Read more

A few days ago, my laptop completely shut down on it's own while not being connected to the charging port. The next day I plugged in the charging port and assumed it was charging. Later on I tried to turn on the laptop and it didn't come on. I noticed that the light next to the charging port didn't come on either. What can I do to fix this problem. It's not charging or coming on at all.   Please help!!!
