Computer only boots up sometimes, power light on if it doesn't

Q: Computer only boots up sometimes, power light on if it doesn't

Hello,
I would greatly appreciate help with my problem. My PC, an Acer Aspire AM5641-U5630A with Windows Vista, only starts up sometimes. When I press the power button, the blue power light comes on and the fans start sounding. However, after it quiets down there is no beeping noises and a display does not come on. On times in which the computer does turn on, a beeping noise is heard and an Acer logo display comes on before it proceeds to start up like normal. Once I'm past the Acer logo the computer works fine. It seems to be random as to when it powers up but I have tried an upwards of 20 restarts before.

Thanks,

Preferred Solution: Computer only boots up sometimes, power light on if it doesn't

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 only boots up sometimes, power light on if it doesn't

This is most likely caused by a weak or failing power supply. Open up the case and make sure that the fans are running and everything is free of heavy dust and other debris...

Hey, i've got a major problem, probably motherboard issue, so i'm posting it here, to make sure it's my motherboard.

-When i turn on my computer, it does really nothing, even the power light on the front isn't flashing, only the one below (there are two LEDs outside) blinks once! Then it turns off.
-When i remove every other hardware (Except the ones inside the comp.), same happens.
-My computer is connected to the power cord, and when i start up, i clearly hear the fans.

Thanks for helping.
 

A:Computer doesn't start, and no power light

first thing to try would be to swap power supplies...

if new power supply works, then the old one is dead
if new power supply doesn't work, then the motherboard or CPU may be dead
memory may also be preventing the computer from starting, so remove a stick

if you are using an internal speaker, does it beep in pattern or nothing at all?

I’m working on my daughter’s MSI A6200 laptop running Windows 7, Home Premium, 64 bit.

The computer was freezing up from time to time and then stopped working. It hung up when I tried to reboot. I went to safe mode, used msconfig to turn off all system services and start-up programs, rebooted but no change. Rebooted in safe mode with networking but all network connections are gone, the wireless adapter seems disabled but it does show in Device Manager. Interestingly, the “sleep” light on the laptop is lit. I opened control panel and clicked on Power options but nothing happens.

I downloaded Norton’s emergency bootable recovery tool and booted via a USB drive. I scanned the laptop and it found a virus but I’m embarrassed to say I didn’t write down what it was (I foolishly thought I was done). I ran it again and it came up with nothing. There may be a log somewhere but I couldn’t find it this morning. I have a feeling the virus did some damage before I removed it.

Can you help me repair my laptop? Get my wireless adapter back and resolve the power/sleep mode issue?

Thanks very much!
Steve

A:Laptop only boots in safe mode, no wireless, sleep light lit, no power options

That really, really sounds like a motherboard problem.

To eliminate hardware as a possibility I'd back up the data and reinstall to see if it fixes it or not.

Alternatively, you could try booting it off of a linux live distro CD to see if it keeps up its shenanigans.

People write bugs to do strange things though. Is the sleep light lit prior to windows actually booting, or only when in windows?

Occasionally I have this problem occur once in a while but I usually fix this problem by unplugging
the power cord to and replugging it back in. I think the problem lies in the graphics slot or the graphics card itself. I have disabled my on board graphics card and added a PCI graphics card for 6-7 months now. Like I said it happens once in a while but now this solution isn't working for me. Any ideas?

When I got home from work tonight, my Win7 desktop appeared to be asleep, which is normal. I hit the power button to wake, it, walked away, and when I came back, it was not up as I'd have expected.

I looked more closely and something really weird was happening.

The fan would turn on and the power lights would come on. Not sure if I heard the HD (there's an OS C drive, and mirrored data D drives). Three seconds later, it would power off, without anything ever displaying on the monitor, no bios screen, nothing. This would just keep repeating.

I managed to get the CD drive open and put a boot disk in, but the whole sequence happens so fast that it doesn't even recognize the CD or try to boot from it.

Right now I have the computer turned off and unplugged, and hope that this will rectify itself with the passage of time.

I'm kind of stuck here...

First what happened: last night my computer froze so I turned it off and then back on. However, when I did, the monitor just remained in standby as if the computer was not on. Everything on the computer seems to be working ok (fans going, lights on, etc). I also don't hear any beeps during the startup.

I've been browsing a lot of forums trying to figure out what is wrong, but I'm somewhat lost. I don't know that much about computers...
It seems some of these forums say the main culprits for a problem like this are the graphics card or the motherboard? Is this true?

Since every thread always has someone asking for specs - here they are:
Intel i7 940
Asus p6t intel x58 chipset sle/crossfirex mainboard triple-channel x
800w power supply
1 TB SATA II 3.0 gb 7200rpm HD
3 x 2GB DDR3 PC3 PC1333
1 x EVGA nvdia gtx 260 896mb pci-e
windows vista home premium

What I've done so far:
I have tried unplugging it and holding down the power button in the front for about 1 minute. 90% of the time this did nothing. One time it started to boot correctly with the monitor only to freeze during the windows load up bar and 1 other time it didn't even make it that far...
I have tried using another monitor on the computer. Same problem. I have also tried using my main monitor on another computer and it works fine.

I've been fighting this problem for months and haven't found an answer anywhere but maybe you guys can help. My computer seems to boot fine, but nothing is displayed on the monitor. The power light on the monitor ON button just blinks amber. If I wait a minute or so and then hit the reset button the computer reboots and the monitor comes on. The computer started doing this about 6 months after I built it. Once in a great while it will boot up on the first try, but it's very rare. I was thinking video card, but have unseated and reseated it a couple of times to no avail. I also got a new battery on the motherboard thinking it was having a problem. Now I'm thinking power supply or BIOS - any ideas?

hey,
When i went to bed my computer was working fine. but when i woke up (8 hours later or so), When i press the power button nothing happens, not even a choke to try and start up. The weid thing is that when i turn on the rear power switch, the motherboard green LED is on. So im not sure if this is consistent with PSU failure? I would have that PSU failure for sure but now im not certain.
i have tried:
Using a known good power socket.
switching the power and reset buttons on the motherboard to see if it was the siwtch
Short circuiting the on switch on the motherboard.
When i unplug the motherboard power cable from PSU, the green LED turns off, when i plug it back in it turns back on.

Does anyone know if its a PSU problem or somethign easier? Because it's really throwing me off. I think i have to be getting power, since the mobo LED is on.
Thanks
Andrew
 

A:Computer doesn't turn on, but mobo LED light on

Hello and welcome to techspot.

I'm not good at all when it comes to this case, but coincidentally, i have the same issue last year.So i decided to write some possible reasons :
1. PSU failure (+12V A rail is too low)
2. Capacitors leaked
3. Heatsink and thermal gel not installed properly
4. Few drives problem such as HDD or optical drive
5. short circuited cables inside the case.

So far, when this problem happens to me, i could not turn on the PC whenever the HDD is attached. But when i unattach it, the computer would on.
Or another issue, i have a fan in the case which i have not installed yet. Accidentally, when i move it with a pincer to the correct position, the metal parts of the fan get in contact with the CPU case. Straight after that my computer turned off, BUT the CPU LED is on.

Well, let's find out more about your computer, can you give your system specs here?

Hello!
My father-in-laws desktop computer is acting funny. When the power button is pushed on the light around the button comes on and the fan starts but thats all it does. The fan usually comes on and is quite loud and then it quiets down and you hear the rest of the computer booting up.

Hello,

I replaced a video card in my computer and now the power light will not illuminate (see attached photo). The computer is functional. The card has lights and they are working fine.

I've been told to make sure the connections om the motherboard are secure and have done that (or so I think). I was also told that I'd need a new case by the store that I bought both the computer and video card from. The power light came on perfectly prior to video card replacement. Reason for the replacement was that I wanted 4 ports instead of 3 on the card.

What are your thoughts on the issue and/or alternative suggestions for a fix? Since the computer boots and is otherwise functional to include the new card, I will just deal with lack of a power light if the case needs to be replaced.

Thanks for the help!

A:Computer shuts down with blinking power light

It sounds like you have a driver problem, and the blinking light suggests that the computer isn't actually shutting down, its actually going into what vista now calls 'Sleep', or standby in XP.

I had the same problem with my desktop the computer, try updating your motherboard drivers and video drivers from the relevant manufacturers websites. Give that a try and if it doesn't work then let me know and i'll give you another possible solution.

Sure doesn't sound good

Off top of my head, fan spins, nothing else comes 'on', possible

Memory / CPU / Video card / Motherboard malfunction.
PS: if fan comes on, but no power light, could be a faulty/buggered up power supply too I suppose ( I woulda thunk the power light would come on before any fans spun )

DOH !!! can't even blame Microsoft on that either.... its hardware.

I can't get my computer to boot at all, not into CMOS, not anything. It doesn't power up. And the green LED light that comes with the power supply is constantly flashing.

This has happened before, normally when I wait a while before trying to boot, I can get the fan inside the power supply to spin just a little bit. The last time it happened, I fixed it by taking out one of the memory sticks.

I have no other power supply to test, so I don't know whether it's a problem with the motherboard, or the power supply. However, I notice that when the 24-count connector pin isn't connected to the motherboard, the light doesn't flash, it just stays lit green. When I plug it in, it starts flashing again. Maybe it's the motherboard, maybe the pins are bad, I'm not sure what that suggests.

Is there anything I can do to diagnose this clearer?

Desktop Computer Won't Boot Up, Monitors are off, but Power light is on

Guys, this is what has happened.

(1) A few times, when I get home from work, my computer had unexpectedly turned itself off
(2) After pushing the ON button, the light turns on, but it doesn't BEEP and doesn't boot up
(3) The monitors are blank
(4) The fans are on

I've tried taking out all the components and wires and putting them back in, but nothing is doing the trick. The funny thing is that this has happened many times recently, but when I turn the computer on, it's fine. Now, this time, it just won't boot up, even though the power is on. My computer was behaving normally prior to this event.

I have an Acer AM5630-U5209A with upgraded 600mw power supply.

Thanks a lot for any help guys,
Josh

Help please! My family and I own the HP Envy 23 all-in-one PC. Unfortunately most recently it has stopped turning on. There power light doesn't show nor are there any noises/ beeps. We have checked the power source, so that doesn't seem to be the problem. We purchased a new adaptor (120 W). I've tried the F10, down button, enter button sequence using the wireless keyboard. Nothing has worked.

dell xps m2010 wont start up ,blue power light and bluetooth light stay on,i have been searching posts in other forums as well as this one and i thought i`d narrowed it down to the graphics card,i was right to an effect,my approach was to take the xps apart following dells website documents,while i had the top (dvd drive) off ,i noticed that the graphics card screws were really loose (this was my first job)...i tightened these.The top(dvd drive ) i re-connected ,but propped it up at an angle so i could still see motherboard and parts,(warning!be carefull!!)electric!! ...attached power cable and pressed power button after half a dozen times pressing this it came to life.I noticed my fans were working and thought this might not be my motherboard after all ,no overheating happening...then it froze on windows xp ??it was a start !another 6 to ten times pressing power button it worked again this time not freezing.went into bluetooth with usb mouse and paired keyboard ,made system restore point and restarted .It took maybe 4 times with it being glitchy(freezing ..not powering up) ,but when it does load xp without freezing try restarting windows xp and then it eventually finds its feet!!!my xps 2010 is running ok now.jimb

I will turn it on and after a minute or two the monitor goes to power save mode and the hard disk light goes from off/blinking to solid on and the power light stays on.

I have reinstalled the operating system and i thought that fixed it. I had SP 1 i installed all of my updates and SP2 and it starting to do it again (it will do it in SP1 but not nearly as often or when i run a flash heavy program: PSP Video or even the Scion website).

It will not do it at all in BIOS as i did every test on the diagnostics page for my hard drive (all pass) though if it turns off it usually turns on and runs dskchk and it wont stay on for that

In safe mode it is also fine it will not turn off once

I dont know what i did last as it was fine then i was gone for a month and I had it unplugged etc., came back hooked it up and it started doing it after a little while

I have taken a can of air to every inch, switched the Flat cord going to the HDD from the Motherboard.

All fans run fine

Thats all i can think of right now ask me anything else you need to know

I'll give this forum a couple of days/a week maybe then i'll take it to a local shop to diagnose it

Much thanks to anyone who has any idea's

Hi. Tonight I had a problem with my laptop. It was in sleeping mode, and when I open the lid there were no mouse function and no touch screen function. So the only thing I could do was to press the power button for 3 seconds to turn it off, but it didn't completely, because the screen turn off, but the power button light is blinking just like when it is on sleep mode, and I'm not sure if the hard drive light was on, off or blinking before this, but now is blinking. I press the power button and nothing happen, I press it for 3 seconds and nothing happen. I even did the HDMI connection to another monitor, but both monitors don't show anything, not even recognize that something is connected to the HDMI port in the new monitor. There is no sound, nothing, just the 2 blinking lights. What should I do? Thanks PS: I'm not sure if it's Windows 10 32-bit or 64-bit. It was upgraded from Windows 8

I have an HP desktop. I accidentally hit the standby button on the keyboard. It started to put my computer into standby but seems to have completely powered it down. I couldn't turn it back on at all. I've tried hitting the power button and unplugging the computer. Nothing works. There is a green light near the power cord in the back blinking and that's it. I've tried unplugging all peripherals before plugging the power back in. I've also tried unplugging it and pressing the power button a few times before plugging it back in. I just can't get it to turn back on.

I have a Compaq Presario, Windows Vista Basic, around 3 gigs of RAM.

I recently rearranged my room, and when I went to go plug everything back in for my computer, the power supply light started to flicker when it was fine the day before.
I don't remember this ever happening before; it's still green, it just flickers rapidly and I can hear it.
I thought it was a temporary thing, but my power button is completely unresponsive and it will not turn on.

I have had my power supply replaced twice prior, and I fear I may have accidentally surged my power supply when I plugged it back in.
I would like to know if this is the only cause, I have tried different outlets, and even checked to make sure that I didn't mix up my power supply cable with my monitor or printer, but the results are the same.
Even when I unplug any power source, the light flickers and gradually dies, as compared to going out immediately.

The last time I replaced my power supply was around October of 2009, due a faulty fan.
The time before, was October 2007, when the power supply just shorted out.

This time I am completely confused since it was working the day prior, and wonder if my moving it would have caused something. It seems so unlikely, but due to my bad history with power supplies, I am prone to assume it is the same problem.
But if anyone has any other suggestions, please help.

Thank you for your time.
 

A:Solved: Power Supply light flickering, computer won't turn on

Since you moved the computer I would open the case and make sure all the powersupply connections to the mobo and peripherals are tight.

Good afternoon, couple of days ago my computer which is not paid off yet and out of warranty went into a no boot with a soiid Amber light. When I cracked open the case I found my cpu fan was nearly frozen very stiff to turn. I cleaned it out but now curious if my cpu died or the PSU? The interesting part if I unplug all external perpherals from the computer and test it get the solid amber light and on the back by the PSU the green light is out as soon as I turn on the power. If I unplug the power let the system discharge then plug the power back in before turning on the power the green light on the PSU is lit.
Does this sound like a PSU issue? Could it be the CPU? I'm getting no post beeps or anything powering up. Also is this a specialized PSU or can I use any standard ATX PSU this is in a mid tower. The service code is <ADMIN NOTE:Service tag removed per privacy policy>.
Thank you for anyone's help in advance just frustrating making payments on a paperweight.
Sincerely,
Jouster

A:Solid Amber power light computer won't boot Dell Inpiron 530

Does the processor heatsink fan rotate freely?
Does the power supply fan work?
A solid amber power light indicates there may be a power problem or an internal device malfunction.
The Inspiron 530 Troubleshooter and Diagnostic Codes are HERE.
Most generic standard ATX power supply units can be installed, with either a 24-pin or 20+4-pin main motherboard power connector, with or without the on/off switch.
You should be able to buy a compatible power supply from either a local or online computer store.
Note: A power supply with four SATA power connectors, is required.
The power supply replacement procedure is HERE <ADMIN NOTE: Broken link has been removed from this post by Dell>
