Computer wont start, power supply wont start, blinking led

Q: Computer wont start, power supply wont start, blinking led

So I turn my computer off one day only to find it wont start the next day. I open the case up and see the led is on. I flip the switch on the power supply off then on and quickly press the power button. My computer starts but the following time I shut down the computer it again wont start and now the led is blinking. I've never had any issues like this before, any help would be appreciated.

I don't routinely use many usb devices, only my mouse and keyboard and every now and then my ipod. I figure the issue is likely either the power supply or the motherboard. The ps is almost two years old while the motherboard is only about three months old.

Preferred Solution: Computer wont start, power supply wont start, blinking led

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 wont start, power supply wont start, blinking led

It sounds to me like your PSU is the problem, get a hold of another and plug it to your computer and see if that will make it start, if it doesn't it might be BOTH your motherboard and PSU. A bad PSU will burn a motherboard.

So I just recently purchased a new desktop as my laptop fried. I bought this desktop with getting a new video card and power supply in mind. I purchased an ATI Radeon HD5750 which requires one of those 6 pin power cords. The new power supply had what I need.

When i switched out the old 250W for my new 500W, I received no results. The computer would turn on, all fans would run but I would get nothing on my monitor. The motherboard green light would also turn on. When i swapped back to the old power supply, everything still works great. Any troubleshooting tips? Im told that this might not be a great power supply either. Thanks in advance.

I have a pc that's been sitting for about 2 years now, worked great before. Went to plug it back in and it won't start. I assumed the power supply was at fault at first. The green standby light is lit on the motherboard, but just to test I jumped the green and black cables on the 24 pin connector and everything worked great. Reset the CMOS, still no luck. Then I went to check the power switch by jumping the two PWR SW prongs with a screwdriver.

Now here's the weird part, it started up fine the first 2 times. Went to connect the monitor and start it back up with the screwdriver...nothing. I used a different tool to jump the switch, and strangely it worked just fine again. Now, its back to not working, tried several different metal tools and nothing. I have no idea why the switch is only working intermittently? I just tested everything again by jumping the 24 pin connector and that still works just fine.

A:PC wont start with pwr jumper, power supply fine


Even more weird, I've found if I jump the green and black wires on the 24 pin, pc starts, remove the jump, pc shuts down, then I'm able to jump the PWR switch and the pc starts as its supposed to. I've tested this 3 times and it never fails
Why would the switch only work after jumping then removing the jump on the 24 pin???

My daughter has an HP Pavilion DV6, that I have fixed the symptoms of a problem but would like to get to the bottom of the cause. The problem was that it wouldn't start, when you switch on you can hear the fan, the led on the caps lock bilnks continuously, and the led on the wifi key is orange. (It is normally white when working properly.

Having trawled numerous forums including HP I could not find a resolution, many suggestions such as reset the power, clean the memory and slots etc etc, followed by loads of entries from people trying all of these without succes

I eventually came across a post that said he had fixed it by simply wrapping the laptop in a blanket, switching on, leaving for 20 minutes then switching off and on again. This post was followed by dozens of people saying this worked for them.
So, rather sceptically, I tried it and amazingly it worked. The laptop now starts every time without a problem. So aparantly problem solved.

However I would like to get to the bottom of this before it happens again. I want to find the actual reason for the failure and if necessary replace any faulty componants. I am thinking of selling the laptop but don't want to sell it to someone knowing it may fail in the near future.

My guess is that this must be heat related as wrapping in a blanket stopped the laptop cooling and it was very hot when I removed the blanket.
The laptop now starts OK regardless of the temp, I left it overnight and restarted OK.

Hi I made a thread yesterday regarding a minor PC problem I had while trying to install windows XP on my uncles PC the problem was solved thankfully.

I now have an even bigger problem of my own with my PC.
I turned my PC on in the evening and the monitor screen was blank and displayed a blinking orange light, the fan does come on. I doubled checked the wires to see if any were loose but everything is inserted correctly.

What’s weird is the PC that I was installing windows on yesterday was doing the same thing but once you turn it off and turn it back on it would be fine and load windows.
But my one is not even doing that, there is nothing wrong with the monitor has I have brought it recently and I also checked the PC using my brother’s monitor and the same thing happens.

Once I finished installing windows on my uncles PC I turned my PC on and watched highlights of a soccer game so it actually was working last night. But I have no clue as to what has happened?
Can someone please help me?

my computer wont boot and still it wont display.
i already changed a video card and stil it wont.
it have no beep at all and it will not display.

what should i do?

A:guys my computer wont start and wont have a display

does it beep any. if not this will indicate more major problems. (unless you dont have beep speaker installed) a mother board is programed with a set of beep to play if there is a problem like such as three beeps if the ram is not working, 1 long beep if the vid card is not working etc etc. I DO NOT KNOW WHAT YOUR BEEPs WILL BE. if you are not getting these then you need to find out why. see if you have a speaker inside your case. if you do and all of your fans spin but still no action from you pc then you may have a larger problem such as mother board or processor.

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 posted this in the hardware section because i know its gotta be hardware related. On one of my older computers, which is a HP(bought in 2002), wont start at all. Not even the Compaq logo will display, which means BIOS wont start either. so i cant boot at all, or operate the computer in anyway. This happened right after i installed a gig of RAM, i was upgrading from 512 mb to 1 gig, they were 2 different cards, 512 each, and both had 189 pins. I installed them, booted up and nothing.

I really dint think there is a solution for this though, because after that, i put the 512 RAM back in and it still didnt work. Im thinking the motherboard was fried, by static electricity maybe. if thats the case than ill just get a new computer. which leads me to my next question.
How do i access my Harddrive? I have a lot of valuable data on there and an expensive music collection, as well as a bounch of backed up movies.
Any help is really appreciated guys, thanks in advance.

Hi guys.

I am experiencing trouble with my server. There was an overnight power cut while the server was running.

I attempted to restart the server but there is no luck. A few things I have tried:

Disconnecting the hard disk and trying to boot the computer gives it power and the computer stays on, as opposed to when the hard disk is connected, the power of the machine comes on but immediately turns off (the LED's on the front panel blink very briefly.

It was running Windows Server 2000 and I am not sure what the next step is to take in restoring (if possible) the computer to its normal state.

Any help will be greatly appreciated and I thank you all for your assistance.

My parents pc is meant to bring the monitor out of stand by when it powers on, but since the other day it hasnt. I took the side off the other day meaning to test some components with it but didnt bother testing them so put side back on, and since then this problem has occoured.

I have tried the monitor with 2 laptops and they both work, powering it on out of standby when they start. Monitor has been a bit dodgy for a while now, it would have the screen tinted a red or blue/green colour (its just old I'm guessing, doesn't seem to be a loose connection) and it would be ok if you de-gaussed it a few times until you got the right colour, so its not perfect but it does work

I have tried 2 different motherboards in the PC, and 2 different video cards, both of which have worked in this PC in the past, its always the same.

If the monitor is on, but not connected to anything it will turn on and give a message on the screen "no signal, etc" but as soon as it's connected whether the pc is on or not it will go to standby.

This is a problem I had since a few months, but back then it wasn't that irritating. Sometimes when I tried to start my computer it would start up mechanically, so to say; all the fans were working and so were the HDDs, but not the BIOS. Nothing would happen, and the monitor was ever idle. A simple cold reboot usually solved the problem.

Now, like I mentioned, the problem got serious. The computer won't start at all, i.e. nor the fans, nor the monitor, nor the HDDs will ever start up. It just keeps restarting itself every second without any enhancement. I also found a solution for this problem by setting the power supply to 0, and then back to 1 after a few hours(!). Restarting after just a few minutes doesn't work. What's the matter? Have you ever encountered such a problem?

Check your power settings (while the 'puter is on AC, of course).

two other posibilities:
the battery contacts might not be in full contact - to fix: remove battery, clean contacts and make sure they still have a little spring or bounce to them. (if they don't bounce a little, they might not make full contact)
the battery may no longer be holding a charge - only fix for that is a new battery.

The notebook should work when only AC power is plugged in. You dont need the battery inserted.

Does the DC IN LED light up when you insert the AC Adapter?

If it doesn't light up, then either the AC Adapter is faulty, or the Mainboard or another component needs replacing.

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?

Hi everyone- This is my first time here and I need help!! I'm a newbie and not real technically advanced, but here's my problem... A few days ago I was trying to connect my scanner to a USB port and I noticed my mouse got stuck. I hit the power button on the front of the computer to turn off. I rebooted and then I couldn't enter my windows password because my keyboard didn't work either! I then turned off the computer from the reset button in the back. Then I flipped it back and tried to power on my computer and it has never turned on again! I should mention that when I try to turn on the computer there are no sounds, no fans moving. It's just silent and dead. It doesn't try to do anything. Could it be the power supply or motherboard? I tried using different outlets, and changed out the computer cord that runs to the outlet. My friend helped me build my computer about 2 years ago. I have left it running mostly 24/7, which I guess isn't good. Could I have worn out my computer faster? I don't even remember what kind of mobo I have or really anything (I have to look and my friend ordered the parts 2 yrs ago). The only repair I've ever had to do on it was replace the fan about 8 months ago.

Today I noticed that I could not open my start menu with neither the windows button, ctrl + esc, or a click of the mouse. I've also had a problem the last couple of days saving/opening files in one of the programs I used to make music. I tried to go into safe mode to do system restore, but the safe mode didn't boot. It scrolled all the system files on the screen but then just stopped and nothing happened.

So, I tried the other option (forget what it's called) that lets you perform various other system restoration tasks. I brought up the system restore screen from there, but got an error that said something about corrupt files so it could not perform the restore. I checked again, and all my restore points had been deleted.

Lastly, when I click computer, all the drives are blank with no names beside them, only the icons. I can still click them and they seem to be functioning normally, so I don't know if there is a relation to this. I don't know if some registry files were deleted or if there is some other problem. I didn't notice the start menu/safe mode/blank icon issues until I just recently installed the latest windows update.

Sorry if this seemed a little long winded, but I would appreciate help from anyone.

I used the reset button, but it was behaving oddly, the computer was still running but the monitor turned itself off. So I though that maybe I had installed the reset Switch the wrong way. I couldn't stop it anymore so I closed it with the Power Supply Switch. So I opened my case to see if everything was ok, Everything was as it was supposed to be. I played with the connectors a little bit to make sure they were well connected. I tried running the computers again, but it wouldn't start. It didin't make a noise, no fan running, no BIOS, nothing. I was very afraid to have killed my Power Supply or MOBO by closing it the wrong way.

I though that maybe it was just the power button of my new case that was the problem, so I connected the Reset Switch connector in the Power Switch. I tried turning it on and it worked. I was very releaved that it was just that problem. So I left it opened all night and went to work, I also accesed my computer remotely from work almost all day. But Last night when I finally came home the computer was closed, I though it was weird but opened it again and wen... Read more

A:Computer won't start anymore after closing it with Power Supply Switch

Hello and welcome to Techspot.

If after trying your other psu it`s still dead, It`s got to be either the mobo or cpu.

I think for whatever reason, you`ve had a short circuit of some kind and it`s fried either the psu/mobo/cpu.

You`ve seem to have tried all the right things, so I can`t really suggest anything else.

Regards Howard :wave: :wave:

I got a new p4 3 gig with hyperthreading pc. For a while it was working like a charm, on overdrive. But only after a week of use, I started to have problems. While playing very visually demanding games (Battlefield 1942, Medal Of Honor) I would keep gettin those dreaded blue screen of death thingies. I would get one of 3 errors. One said, "IRQL_NOT_EQUAL_TO_OR_LESS_THAN" another said, "PAGE_FAULT_IN_NONPAGED_AREA" although im not quite sure about the NONPAGED part, i know it said non something. And the other one I think I only got once and cant remember exactly what it was, it had something to do with IRQ.

Now on all of them it said it was shutting down my pc to avoid hardware damage. Which it did, I had about 3 seconds to read the screen before my pc shut down. After a while, It got so bad that I would get an error while just browsing the internet with explorer. I tried taking out my vid card and using the on-board video, didnt work. I dont remember if xp stopped starting or not, but I decided I should format my hd to fix the problem. I only have the xp upgrade cd so I had to install win98 first. Win 98 installed fine, except that on the first startup after installation my pc resarted itself and I got the "failed startup, choose an option" thing, I chose normal start up and it worked fine. So then I tried to install xp again. I got to the part where it restarts to install xp from the files copied from cd. During that installtion phase, It said... Read more

I have a DELL XPS laptop that makes beeping sounds and the screen is still black after I pressed the power button.
It makes 5 beeping sounds per interval and goes on until it shuts itself down. What should I do and who should I contact to help me fix my laptop?

A:My Laptop Makes Beep sound when I press power button and it wont Start

Hi AhLong
Thanks for writing to us. 
5 beeps usually means CMOS failure, now it could be the battery failure or the motherboard failure. If your system is under warranty we can get it repaired or else you can check with a local Dell authorized repair center and get it checked. 
You can try another CMOS battery if available.
Do provide us your system tag#, email address and name via private message.

when I press the power button on the front of my pc all the fans and lights come on and spin round as normal and the computer sounds normal (from the inside). But the screen and my key board and mouse (which are both USB) won?t work. This problem has started immediately after replacing my old CPU fan. In the process of replacing the fan we had to take out the mother board and other drives because of installing a new bracket for it to mount on. my thoughts at this stage are either that the mother board is broken (although the new cpu fan still works) or that there is maybe a little cable some where that I have not plugged in properly and is causing this problem. I would be very great full if some one could help and give me some pointers to what it could be and maybe what to check.

thank you

I have an Imedia x2414 and it is approxx 1 year and 3 months old.
