Computer will NOT turn on! Please HELP!

Question: Computer will NOT turn on! Please HELP!

Ok, this problem was created by me messing with something I shouldn't have been so none the less "lesson learned", anyway this is how this debacle got started:I use my computer in my car alot for work, GPS, paperwork that kind of thing so instead of tying up my power outlet with my computer I thought I would install a permanent power supply (Genius). Lucky me there was already a power cord in my car from a previous computer but the connector tip was not compatible with my computer, so I applied logic, right? The obvious thing to do would be to get a cord that would fit my computer replace the cord in the vehicle with it and WHALA!! Right? WRONG! The resulting damage was this:- With the power cord plugged in the battery would hold charge but would NOT charge, nor did the battery icon indicate that the power cord was plugged in. With the power cord unplugged the battery ran off what remaining battery power it had until it went dead, and now.....nothing.......nodda........zilch! What have I done? Is my $1200.00 computer fried? (by the way....the waranty.....expired.....LAST MONTH!!!) Have I really F'd up this time? I guess the obvious thing do to do would be to find away to charge my battery and just use the A/C plug all the time but I would rather fix the problem if possible and put this embarrasing incident behind me! Any help you guys can provide would be GREATLY appreciated!!!!Thanks!!!The system is a Dell XPS Laptop model M1330 runing Windows Vista Home

Preferred Solution: Computer will NOT turn on! Please HELP!

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.)

Answer: Computer will NOT turn on! Please HELP!

will it boot up off of AC power? if so you may have just fried the battery and purchasing a new battery may solve your diliemma. If it wont boot off AC power it may have done a lot more then that.

I have a bit of a strange issue with my computer. Forgive me if I'm a little too descriptive, but I'm not sure which details are relevant and which are not for such a problem. First, the specs:

Model: eMachines T2984
Operating System: Windows XP Service Pack 2
Processor: Intel Celeron D Processor 340, 2.93 GHZ, 256K L2 Cache, 533 MHZ FSB
Power Supply Unit: Bestec Model: ATX-250-12E REV: P7
Motherboard: I can't tell, but it appears to be an Intel motherboard by the number of Intel labels on it
RAM: 512 MB DDR SD originally, added 1 GB a couple of months ago
Let me know if you need anything else...

Yesterday, I got home from shopping around 1PM, and I tried to start the computer. I pushed the power button, and nothing happened. I checked all of the cords, and they were all plugged in. Not knowing what else to do, I opened up the case to see if there was something obviously wrong. The only thing that I noticed (other than a bunch of dust) was that the power supply unit was still hot. I shut the computer down about 5 hours earlier after about 20 minutes of use, so it seemed strange that the power supply was still hot. I unplugged the computer just in case there was some sort of fire hazard.

At this point, I called a friend who suggested that the problem might be with the motherboard or the power supply unit.

A few hours later, I plugged it back in to try to get it to work. As soon as I plugged it in, the entire unit suddenly started "running" by itsel... Read more

Answer:Computer Doesn't Turn on, Fans and Some Lights Turn on Automatically

I would suspect that the Power Supply Unit (PSU) is going south. If you have a spare one laying around, install it and see if the problem goes away.
You can buy a new,better PSU from Newegg for about $40.00. I have used a Thermaltake 430 watt in one of my machines for some time now and it works well.
You will have to check the size of your PSU to be sure a new one will fit into the eMachine.
Here's the page with that PSU on it. It's the last one on the list.

I just put together my first computer 6 months ago. It abruply shutdow in the middle of writing a paper for school. I couldn't turn it back on right away. after trying a few times, it turned on. All the fans are working even the fan on the power supply, the motherboards lights are on. My graphic card in on the motherboard. I think it might be my power supply because when I first put it together I didn't plug in the smaller power connection to the motherboard and the same thing is happening, black screen. It's like my computer isn't giving my monitor any feed. I will have more info when I get home. I can't get in to bios or safe mode.

I am using a client computer that is connected to a modem via a LAN cable which is in a neighboring house as far as about 50 meters. The host computer is there. The host computer is only using Internet Connection Sharing (without a router) to share its Internet connection with me. Within this network there are only two computers, the one I use (as client) in my house and the other one is the host computer as I mentioned earlier.

How do I know that the host computer is being turned on or off?

The purpose is to know so that I can use all the bandwidth from the modem when the host computer is not turn on. Because there are no restrictions on bandwidth from the host computer, and I just wanted to use all the available bandwidth only when the host computer is not turned on.

Both computers use Windows 7.

after serching all night to find out why his computer is in limbo, i leave my brother's house without finding needed help. his computer won't turn off...the fan, a couple little lights until he unplugs it from the wall. first, the computer did a restart all by itself, he said, then it would not turn on, except the fan and little lights inside that won't turn off. he took out the hard drive and it functions in his other computer...he puts the hard drive back into the new computer and it will not turn on or completely turn off that fan. he tried the "hold the on/off button for at least five seconds" step and nothing changes. he has had the computer for a year and a half, so he really wants to figure this out. how can he even get it to turn on so he could do a safe start up? so far we cannot find a way to troubleshoot. he have checked the cords, perhaps there was a freeze up that began this loop and that's why the fan stays on? please say this is something you have heard of and there may be a solution. the advice we have found usually goes back to buying a new computer. thanks in advance, tea

Hi, I have a problem with windows XP. Everytime I turn off my computer by clicking on "turn off computer," I receive an error message popup that states "Windows Explorer has encountered a problem and needs to be closed." After that pop-up message, the computer freezes for about a minute and goes back to its normal format (desktop) and the computer DOES NOT TURN OFF.

How do I turn off my computer without unplugging the computer? I try "ctrl+alt+del" to go to the windows task manager to "shut down" the computer but..the computer restarts again and doesnt turn off. Do I have a virus or a windows explorer problem? and how do i fix it? thank you

I use my laptop for school and, by keeping it on power saving mode, usually get through two school days without charging my laptop. Ever since I've downloaded Windows 10, (1) my computer doesn't shut off all the way when I close it, which drains the battery, and (2) every time I charge it, it turns off the power saving mode, which is really annoying. This is especially annoying when I don't notice it isn't on and my battery drains even faster. Is there any reason it won't turn off? Is there a setting I can use to keep the power saving mode on at all times?

Answer:Why won't my computer turn off all the way and why can't my computer stay on power saving mode?

Your system might have a virus, try to scan using Malwarebytes, Superspyware , Trojan-Killer. Restart your system then try to download Hitman Pro then Run it. Then optimize your system using Ccleaner. Hope this would help.

As the title said, my computer freezes during games. When it freezes the screen just stop at the last frame (so no black screen or anything like that) and I can hear the game for about a second before it turns to a low clicking sound. At which point I have to manually shut down the computer and restart it. Nothing else works. Then I get the usual question of how I want to start the computer, I always pick “start normally” and it’s like it never happened.

I think it’s because the GPU is overheating, because that’s the only component that’s really hot. When I check the temp while playing it’s usually building up to about 60C (24-30C on idle) and stays around that number. And it fells really hot when I touch it after it’s happened. The only problem with that theory is that I can play every game out there usually on the best setting (haven’t tried every powerful game out there) and not a single problem with lag or such. Then again, I’ve never had that problem with MW3, and the temp stays around 50C on that. Not to say that the GPU is really that great. It’s average at best, but I’m not a hardcore gamer or anything so figured I didn’t need the best.
I built the computer myself in June 2011. And it went fine without any problems until maybe 6 months ago, not really sure when it happened.

Here’s what I’ve done so far

Answer:Computer Hangs When Turn Off Computer Selected In Windows

Welcome to BC! There are many possible causes, however there is one common cause. Often XP's exit sound file gets corrupt and if it does not run then XP won't shut down. I am not sure based on what you have told us so far if this is the issue or not, but let's see:Go to:Start > Control Panel > Sounds, Speech, and Audio Devices > Sounds and Audio Devices > Sounds tabUnder Program Events scroll down until you see Exit Windows. Highlight Exit Windows by clicking on it once. Then under Sounds choose None. Click Apply and finally OK. Reboot if possible, or shut down computer and restart manually. Once it is up and running, shut down computer by going to Start > Turn Off Computer. See if it will shut down on it's own now.If it does, the only difference will be that you will not longer hear the 2 seconds of music that XP usually plays as it shuts down.

Answer:Solved: computer beeping sounds when i turn on computer

There are three possibilities here, all related to your memory.

1) You have forgotten to fit your memory back in.
2) Your memory isn't properly seated in its slot(s)
3) You have killed your memory because of not following antistatic procedures.

I'm suspecting it is either 2 or 3.

First of, my monitor exhibited signs of flickering during start-up, but only minor ones and would just stop at the 'Welcome' screen of windows so I didn't give it much thought. Iv'e been using it with the cpu the same time I bought the monitor.

But after some time, the flickering got worse. It went from 1-2 second interval flickers to a whole 10 seconds of blackness before it showed anything.

Now,Iv'e got a new cpu but still using the old monitor. After a day or so, the monitor exhibited the first symptoms of my first cpu, so I just dismissed it. But after a week, It got a hell worse, before I even start-up my computer, the monitor doesn't show Analog/Digital at the top-left corner of the screen. PLUS my cpu keeps restarting after I pushed the ON button after 10 seconds or so.

My question, Is the monitor responsible for the restart and what could be the reason for the flickering?

Thanks for a fast reply.

Welcome Pokeman5 to the windows 7 forums.

The graphics card might be your culprit. Please update your system configuration settings under user cp so that others can maybe help you.
Usually the monitor won't stop your machine from booting. The graphic card most likely be the cause.

There is also the possibility that your power supply could be defective or going bad. Lots of possibilities.

Ok well, my computer is pretty old, but its not THAT old, it has always worked very well, and all of a sudden one day it froze and i tried turning it off but when i went to press the power button it wouldnt turn off, no matter how many times i pressed the power button. so i had to turn off the power switch in the back of the computer. it did this consistently so i decided to format my computer and delete the partition stuff like that, but it still did it, and i even virus checked and there were no viruses.

my computer freezes out of nowhere at random spots (startup, windows, my desktop, etc) and when i try to turn it off the power button doesnt work so i have to turn it off by turning off the switch at the back of the computer, please help me, i don't know whats going on!

Answer:URGENT PROBLEM: Computer freezes, but can not turn computer off

Try holding the power switch in for at least 4 seconds. There is a entry in BIOS for instant off and 4 second delay. Yours is probably set to 4 seconds. Delay is good as it prevents accidential power offs from hitting the switch by mistake.

If you are hiolding the switch in and it isn't powering down there are two possibilties. Switch is defective or connector has came off the header.

Hi TheRealDanny.

The crash dump (a Stop 0x3B one) is not saying anything in detail about the probable cause of the BSOD).

Test your RAM modules for possible errors. How to Test and Diagnose RAM Issues with Memtest86+
Run memtest for at least 8 passes, preferably overnight.

If it start showing errors/red lines, stop testing. A single error is enough to determine that something is going bad there.
If it does not show any error, enable Driver Verifier to monitor the drivers. Driver Verifier - Enable and Disable
Run Driver Verifier for 24 hours or the occurrence of the next crash, whichever is earlier.



   Information
Why Driver Verifier:
It puts a stress on the drivers, ans so it makes the unstable drivers crash. Hopefully the driver that crashes is recorded in the memory dump.

How Can we know that DV is enabled:
It will make the system bit of slow, laggy.



   Warning
Before enabling DV, make it sure that you have earlier System restore points made in your computer. You can check it easily by using CCleaner looking at Tools > System Restore.

If there is no points, make a System Restore Point manually before enabling DV.

Just got a new to me P3 computer up and running. Sometimes during star up it does not recognize the PS2 keyboard. Which makes it hard to go into my password protected User ID. When trying to shut down it will keep a few things running like some fans and the CD drive. But it does not sound like the Hard Drive is spinning.

If I use the XP to shutdown it goes into this limbo stage of neither off nor on, same goes for the power button on the front of the computer. It will either start up the computer or turn it to the limbo mode. Upon starting up, I can use the mouse to get it all the way into a non password protected XP users screen but can't do anything without the keyboard working. In the process of setting up I have had everything working earlier today but this keyboard and limbo status has been an intermitent problem. What should I try?

Now whenever I turn the computer on it won't respond(Goes to a Blank Black Screen) and the only way I can make the computer respond is to go to safe mode and UN-install the Graphic Card, then restart the computer back again. Once I've done that the computer would work, but I can't watch Videos or play Video Games on the computer. There also would be these little blue lines on the computer screen (Sometimes their would be alot of the lines and sometimes the lines would be made by the trail of my mouse).

I've tried lots of ways to fix the computer. I've tried:

- Un-installing and re-installing my graphic card (Nvidia Geforce4 MX420 graphics card with TV-Out) that came with the computer.

- Rolling Back My Graphic Card.

- Updating My Drive from Windows Update.

- I've tried using a program that test my computer and tells me whats wrong with it. It said I got a problem with something like the VIDEO MEMORY CARD and I don't know what that is.

Is the Only way I can fix this is to buy another Graphic Card. I do not want to waste $200.00. Please Help Me!

Hi all.
I moved out of a 14-year-old case (Gateway) and into an Ultra brand Gladiator mid-tower.

I have an EVGA nForce 650i Ultra Motherboard, and a "Power Up" brand 450-Watt power supply.

The setup worked fine in the old case, though Windows was freezing regularly after 15 minutes. I figured that was related to the hard-drive, since it wasn't tightly mounted, and I wasn't using enough cooling fans. So I got a new case and cannabalaized a fan from an old computer.

The power outlet and cord are good, and I swapped out the power supply with a 230 watt unit, and pulled the switch from the old case, but neither powered on the computer. Nothing seems out of the ordinary with the switch on the case I bought.

Did I buy a defective unit? Is there something I'm missing or should try again? Something else? Thanks for the help.
 

Answer:Changed computer cases, now computer won't turn on

Have you considered that going from a 450 psu to only a 230 might have something to do with it?

Is the motherboard shortening out by any part of it touching the case?

Hello there, recently, I've been having an issue with my PC. Randomly, all peripherals (Monitor, Keyboard, Mouse, Speakers, etc.) turn off, but the computer stays on, and I need to turn it off by flipping the power off, and once I turn it back on, it boots normally and such. Like I said, the times this happens seem to be completely random, though I believe it has only happened at night, but that may be just coincidence. I have used virus scans, and nothing has come up, so I don't believe that's the issue. I haven't made any significant hardware changes recently either. Does anyone have an idea of what could be happening?

Get into the motherboards bios by pressing a key noted when you first power up the computer. Look for "hit F? for setup" or something like that. Reset the bios to defaults

I don't know if this problem is already in here but I wasn't about to look through 50 pages of topics to find it if it is.
Last night the power went out at our house, my computer was on, and obviously it went off, I had a surge strip hooked up to it and all that stuff, but for some reason my computer won't turn on. When I press the power button the lights will flash on and the fans will start and will seem to turn on but there are no external beeps. Then I can't get it to do that again unless I flip the power switch in the back a couple times unplug it and press the power and restart buttons again. Then maybe I will get it to flash but not always.
I have a pretty powerful computer with a nice video card which uses up a lot of energy, I was wondering if it maybe was my power supply. My brother is very good with computers and I called him he said that maybe I need a more powerful power supply. Mine is 370.5W and he said maybe put in a 400W one. Is he right? Or is it another problem?
 

Answer:Computer won't turn on

if you had a power surge, it could have goofed up your computer. just beacuse you have a power strip doesn't mean you have a surge protector. it probally is your psu but the psu could have burned out somthing int eh computer.(no likely, but it could have happined) and if you do get another psu, jump up the wattage a bit more than just 370W to 400, go for at least 450, if you decide to upgrade later you will be happy you got it.

Hi, I have done a heap of research on many, many sites in an attempt to get through this problem. I am hoping someone here can help me with my problem:
I have a Asus P5B Deluxe Motherboard. I have a ThermalTake TR2-550 power supply. I run Windows XP with all updates. I won't go into what else I have in this unit, only because I don't think the other items are causing my problem, but if you need the other details please let me know.

I have had this computer which I built myself just over a year ago. I have only medium skills with computers so go easy on me. I do a format about every six to 8 months just because I can and I like to clean it all out.

Two weeks ago I did my usual format and reloaded xp. All went well and got everything up and running again Ė I may be wrong but I donít think this problem is related to the format as I have done this many time before with no problems. Suddenly two days ago, I went to shut down windows xp and all went as normal - except when windows shut down, I noticed that the power light and hdd lights stays fully on and also the fans inside keep running - never happened before.

The only way to get this computer to stop completely is to unplug the power supply (or flick it's switch). So I did this, and the turned it back on. The same lights and fans kick in again and it just sits there like this. So I then press the power switch and then I am told that CMOS checksum bad, overclocking failed and CMOS Date and time are not set... Read more

I have a problem with my computer. It just won't turn on! Its an eMachines desktop with a Celeron D at 2.93 GHZ, 512 MB of RAM, and a 80 GB hard drive at 7200 rpm. It can't be more that 13 months old, and I think the model number is something like T4010.

Yesterday evening I went to turn it on only to find that it was totally unresponsive. Nothing happens, *at all*, when the power button is pressed. No sounds, no lights, no internal activity.

The computer and all accessories are plugged in. No wires/cables are damaged.

The only thing I can think of - and quite an obvious cause of damage - was the giant lightening storm we had here. But the computer was plugged into a UPS battery back up and surge protector, a very expensive one (Sigh). It was working and fully charged during the period I was away form the desk. Further, the power to the house never went out and the lights never even flickered. I tried another PC (which was also on and running during the storm) with this PC's cables and the UPS, it works.

It is completely protected by Norton antivirus, and supplemental AOL protection. (Not conflicting.)

I opened the case and didn't observe and physical damage. The power button is mechanically functional. (A small green light is visible on the motherboard when plugged in, but everything else looks totally dead.)

Any ideas what this might be? Thanks.
 

Answer:Computer will not turn on.

You could trace the power button wires back to the motherboard and make sure its seated on the pins securely. There is a tiny chance that it somehow worked loose (heating/cooling cycles). The switch also could have gone bad. To test that figure out what 2 pins it goes to and short those out with a flathead screwdriver, it doesn't have to be a continous connection (in fact that won't even work) just needs to make a connection between those 2 pins for about the same length you leave your finger on the power button.

If that fixes it then there you go. But it probably won't, in that case your power supply or motherboard could be screwed up. Check the cord plugging into the computer to make sure its getting 110-120V that little green light won't always indicate a good power supply.

Answer:HELP! Computer won't turn on...

Is there a switch on the back near where it plugs in? It should have a "O" and a "-" you want it on "-" assuming yours has one (some PSU's don't have these, mostly DELL's and HP's).

It wouldn't be a software problem, because they wouldn't affect the computer until the software loaded, so it is definately a problem with your hardware.

Answer:My computer won't turn on

Sometimes electrical components needs to have all power sources removed and reintroduced to work properly.  Try performing a hard reset first, if it doesn't work then we'll move to the next step.  To Perform A Hard Reset Shut down the computer by going to the Start menu and selecting shut down. (If you have no display, hold the power button down for  5 seconds); (if the computer doesn't power on, move to the next step)Disconnect the AC Adapter from the notebook.Remove the battery from the bottom of the notebook.  There will be a switch/button to eject the battery.Wait at least 1 minute with all power sources disconnected.Re-insert the battery and reconnect the AC Adapter and then attempt to power on the notebook.

HI everyone.

Recently i bought a new custom made computer from the online store Nirv Australia through ebay. I used it well for 1 day just installing anti virus and a few games and such nothing major, and then last night i went to dinner with the computer on and when i came back 20 mins later it was off. I cannot turn it on now. Although everytime i hit the reset button on the motherboard or turn the power off and then on and try to start it up all the fans and the blue lights will start up for a split second, (the lights flash blue and the fans move a tiny bit).

I've contacted the maker through email but they havn't replied and i was wondering if it was a small issue that could easily be delt with from the help of someone on here.

Has anyone ever encountered such a problem or can anyone help me with it?

Thanks so much.

Sorry for this odd question, but someone who knows a lot more than me about computers, told me that it's not good for a computer to be turned on and off a lot. Let's say, for example, I use my computer 5 times per day, and I turn it on and off each time, would it be better to leave it on all day, and just turn it off at night? To me it shouldn't matter other than the on/off switch getting a little extra wear. So, is he right? Thanks. Ed.
 

Answer:Is it ok to turn computer on and off a lot?

Well i would say no it would not harm it.I do it some times but most of the time i leave mine on all the time.Turning it off and on should not harm the computer.Its kina meant to be turned off lol thats way they invented the off and on button just make sure you log off with the windows it self not the button unless you don't have any other option.

I know there will be alot of different possible answers but I figured I would at least post it up. I built my own computer a few years ago and it's been running great. I was having a heat issue at one point but I layed down some arctic silver and that fixed the problem.

Well two days ago my computer just started freezing randomly. I'd have to turn it off and back on only to have it freeze whenever it felt like again. (It could be 3 minutes in or 2 hours in).

I opened up the case and blew a bunch of dust out. Was hoping that it would fix this issue. It didn't.

I took the heatsink off the cpu and figured maybe I should clean off the CPU and heatsink and place new arctic silver onto it. Well when pulling off the heatsink the CPU was stuck to it and I bent two prongs. After swearing at myself I carefully straightened them out so they looked like all the others. After that I completly cleaned off the heatsink and top of the cpu. I place the arctic silver on, spread it out evenly and placed the CPU back on the motherboard. It fits back into it's spot nice and the little lever goes down to hold it in place. I attached the heatsink, closed up the case, re-attached all the cords, flipped the swith in the back of the computer, hit the power button..... and nothing! I checked to make sure everything was plugged in ok and everything seams to be in tip-top shape.

Answer:Computer won't turn on!

1. did you slapping yourself loudly? If you does, can we have a video of that?

2. Welcome to Techspot, Fetter.

3. Sound like your power supply is shot. Please have the power supply tested to confirm that problem. If it does, here you go. Buy another one, it should cost you 20 to 40 bucks for generic one ( last 5 to 1 years ) or you will have to fork over 50 dollars for a quality one, such as enermax.

4. Like you explained, that you have a heat issues in the cpu area, i suggest you to go out and buy the dual fan power supply to eleminate the air circulation waste.

5. Did you bent your Pentium 4? Did you break off any pins? Can you please take it off and confirm that?

6. To make sure, your motherboard and power supply is on, you will need to refer to # 5 and # 3. Try # 3 first.

7. If you have to buy new pentium 4, the used pentium 4 should cost 15 to 70 dollars, no big deals. Make sure to check it up on tigerdirect.com

By the way, I can see the Pentium 4 3.0gHZ for 77 bucks. It is affordable. Plus, I don't think you have a HT compatible motherboard, since you haven't indicate what kind of board you are using. Please give us your motherboard information, so we can determine if you are able to run in HT.

Here is the link.

sup,

i just got my six channel diamond DT-688 PCI sound card in the mail and the thing is giving me some crazy problems:

after some time trying to find out what the problem was it came down to the fact that as long as the sound card is inserted into any of the PCI slots the computer refuses to turn off as long as the power cord is attached to it. i installed the drivers correctly and the sound card works perfect, except for the major problem that it won't allow my computer to turn off!

i checked the bios, reinstalled the drivers, attached it to different pci slots, and took a look at the windows xp power saver options. i even messed with the jumper cables on the card itself and that made no difference what so ever.

my friend and i came to the conclusion that the card is defective but i'd rather find out a fix to this problem then mail it back and all that. hopefully someone can come up with some more ideas for me to fix this problem, i know it's kinda out there.

I have had my IBM Aptiva since 2000 with Win98SE. Never ever let me down, although the OS has, more often than not. I never used the hybernation feature until recently. It didn't work that well, but still I used it for half a dozen times. Everytime It came out of hybernation it would power-up with the hybernation window on the desktop and then go back into hybernation. On second power-up it stayed up and worked as usual. BUT, two mornings ago it failed to turn-on. The two LEDs just flicker.

No HDD noise, no CPU fan, no PSU fan; nothing but the short flicker.

I diassembled the PSU, cleaned it and looked for fried items or burnt smell; nothing. Was unable to test voltages as I do not have dummy load. Internal fuse had integrity and managed to read +5V on two internal leads. As all failed, I reassembled the unit and had another go. The PSU fan worked and thinking all is well, reintalled it. BUT, same problem again. Computer won't turn-on.

Any help is very much appreciated. Thanks!

Power switch or power supply. Watch the fan blades at the back opening of the power supply as you press the power switch. If they turn 1/4 to 1 turn then quit, it is the power supply.
Used ones for an old machine will work fine. About $5.00 Easy to replace with a Phillips #2 screwdriver, removing four screws, then unplug a few cables, plugging new ones in the same place.

How did you test the power supply?

Did you ensure that all power connectors are properly connected?

This is an issue regarding the power supply or motherboard. Since there's no POST beep code (is there?) or anything of the like, there's no other explanation other than these two. You will probably want to RMA it since you just recently purchased it.

I have a Dell Dimension 5000. For the last few months I have intermittently been unable to switch on the p.c. The first time it happened the button I press turned to flashing orange instead of green and pc wouldn't power up. Even when i disconnect it from the mains the power button will still remain lit as orange for a while. I put it into the local repair shop and when they pressed the button it started first time. They checked everything inside the p.c. but could find no faults. motherboard, fan, power unit etc working fine. Cost me £60! I've turned off hibernation , stand by etc. If i leave the p.c. for several hours it will switch on. it's really frustrating. Does anyone have any clues what has gone wrong?

Answer:Computer won't turn on.

I had a Power Supply that acted like this once.It's impossible to deduce what may be the problem, many different parts might cause it - you'll only find out by substitution. Try unplugging the PSU from the motherboard, and firmly replacing the connector first - then try another PSU."Even when i disconnect it from the mains the power button will still remain lit as orange for a while."That's normal - it usually takes a fair few seconds for the power from the PSU to die fully away.

Hello everyone,

I have a 5 year old machine, a gateway, with an Intel Pentium 4 - 3GHz. Windows XP Pro SP3.

Here's the problem: A few days ago, I noticed that my computer was off, when I thought I had put it on "stand by", but then it started normally when I pushed the button. This happened a few times, then I noticed the clock was off by an hour. And then it wouldn't turn on at all, I checked that it was getting power, and it was, I plugged it back in, pressed the button and it booted up normally.

OK so I thought the battery was on its last leg, so I replaced it. I thought the problem was solved, but it isn't. With the box open, and the power on, I noticed a very high pitched sound maybe coming from the motherboard (I can't be sure). there is this green LED on the motherboard, and the only way to start the computer is to disconnect the power for a few seconds (until the green LED goes off) and then reconnect the power and push the button.

So I wonder if I should replace the motherboard or the power supply. I ran a benchmark with the CPU at 100% for ten minutes and everything stayed cool (thanks to the 13.5 Cm. cooling fan) and the voltages stayed normal, so I don't think its the power supply.

Is there any other way to diagnose this problem? I know the power supply is usually the first suspect, but the on/off switch goes to the motherboard, so it controls the PSU.

Thanks in advance for your advice.
Aloha
 

Answer:My Computer won't turn on

power supply even when it keep voltage. change battery on motherboard the clock after replacing should stay at all time. Why power supply?? tell me the brand. check brand and google feedback about it propably is the cheapest one

At all.
Yes, it is plugged in
I press the "on" button, and NOTHING happens, no fan, no lights, nada.

One thing, there was like a red switch above my power socket on the computer, (where the lead goes into) with 230v and 115V, and I switched it, from 203 to 155, and then it didn't work. That might be the problem, I don't know. But when i switched it back to 203v, still, nothing happened.

The last time I turned it off, I'm pretty sure I just shut it down, like I usually do, instead of putting it on stand-by.
 

Answer:Computer will not turn on!

Not sure where you are located but if in US, and you turned it on after switching that, then you blew out power supply though it sounds like it was blown anyway and is your issue. I hope it was blown before you threw the switch because if not you may have done considerably more damage then that. Personal;ly it is time to take the power supply out and to a shop fopr testing...perhaps the whole tower.

I'm going to try to give as much detail as possible.

The PC is a P4 2.53 (I think 915E mobo)...512 ram (1 stick).

PC was running fine. I decided to install a DVDrw. I opened it up and noticed a lot of dust. I used air to blow all the dust out. All I did was put the DVDRW in and plugged it in making sure I didnt dislodge any leads or any other cables. Tried to turn it on...nothing.

The motherboard has a green light that comes on when I plug the power in. When I press the "on" button the CPU fans spins once and stops. I never hear the HD or anything else try to turn on.

I've taken out the memory and put it back in trying different sockets. I've unplugged all the cables and plugged them back in. I've also tried a different power supply which didn't work either.

Now before this happened my pc from time to time would give me the blue screen of death (xp pro system) saying that the memory was overloaded and needed to reboot. But like I said, before I opened it and blew the dust out it was running fine...a little slow but fine.

Any suggestions?

Answer:Computer Won't Turn On!

Hello zepp1, and welcome to T.F.!

Using caned air can cause condensation to form on the surface of what your using it on because it is cold when it decompresses. Give your components ample time and ventilation to dry off. It is possible a small bead of water can be causing a short some where. If it won't boot to POST I would try flashing the BIOS. and double checking critical components. One thing you can do is take out all non essential components like sound card, hard drive, disk drive, even your ram is not needed for the thing to turn on. If it will boot to an error screen saying its missing ram then you can start plugging things back in one at a time to find the culprit. If you still get nothing. try removing and reseating the CPU.

Well, i've had my laptop for about 2 and a half years. i don't use it much for anything, just writing, typing, checking e-mail, listening to music. I was on it one day. I lft and came back and the blue power light was on, but the screen was black. i turned it off and on again, but it was still black with only the lights on. a few hours later, i tried to turned it on and it worked! After that, it would do it again randomly and i'd have to wait two weeks. then it'd be normal with all of my stuff still on it. now i've trying to turn it on for about 2 months and it's only come one twice! yeah. i'm so confused, the compurter is barely used!

My computer won't turn off. What I've been doing is sitting on the off botton for 4 seconds, which works. syrk
 

Answer:computer will not turn off

Hi Syrk,

You don't say what OS you are running. In most all the 4 second shutdown is standard and can be altered in CONTROL PANEL, POWER OPTIONS. Leave it alone and just tap the Power button. It should shut down same as if you went through the Shutdown procedure. Easiest way.

Good Luck, Jim

After waking up this morning and walking over to my (custom built) computer to wake it up (I always leave my computer on), I noticed my computer was going extremely slow. It took a minute to wake up and show the login screen and then after logging in (I could type at normal speed with characters being entered in on the screen at the same time I type them though) it took another minute to show the desktop. When it got to the desktop, there wasn't any mouse. I tried hitting control+shift+escape to get to the Windows process manager but that wouldn't come up. It was almost like my computer was frozen. I then attempt to hit the restart button on my case, nothing happens. I held down my power button on the case for 15 seconds, nothing happens. I switched off the power feeling like no other options left and kept it powerless for several seconds, and now it won't turn back on at all.I'm thinking it might be the motherboard that has gone? Any ideas on what it could be or how to test it?(As a side note, I am not sure if it matters, but I just put a new GTX770 in it this week too)Thanks guys!!
 

Answer:My computer won't turn on now

I found the issue. I am able to turn my computer on via a button directly on the motherboard. I believe the buttons on the front of my case to turn it on/off and reset are busted. Well at least it was that simple!

I recently installed an internal media reader and had to reformat my hard drive (don't ask...). When I set everything back up, everything works fine, however, when the computer is off, it tries to boot back up by itself? You hear the drives (CD and hard drive) get power, lights go on, on the tower, and 3 seconds later, it shuts off. It sporadically does this. Any ideas?

Check in BIOS, if you have Wake on LAN enabled.

Hi, I downloaded the vista transformaion pack from windowsx.net or something like that. Then I downloaded the seven transformation pack from the same website. First I got a criss cross of seven icons and vista icons. Then a few weeks later, I pressed the power button of my computer, it was booting when the vista sign came up. The "working" light on my computer didn't light up. And was frozen there.

My computer won't turn on at all anymore. My monitor is working for sure. I can see everything light up inside my case so I don't think that it's a problem with the motherboard. My HD was making some loud clicking noises so I'm assuming that isn't the problem. How can I check to be definite that it's my HD and not my GPU? I'm running an old 8800GT, but don't think it's dead.

edit: My bios isn't loading either now that I think of it. Before, if I turned it on and off a few times eventually it would boot. Now, it's just a black screen. All the lights are on for it though.

I have an older computer that will not turn on. It tries too. I can flip the switch in the back and push the button on the front and sometimes the light will come on and the fan will turn but then it stops. I have checked all the cables, power supply cable, I even opened the power case and checked to make sure nothing was loose. I don't know why it will try to come on but will not. Any suggestions? Thanks.

A couple of days ago I turned on my computer as normal, it started up, made the usual beep sound, but then I realized something wasn't right.

After switching it on it came to the usual start up screen with packard bell on, then I waited and waited for over half an hour but to no avail ? I'm just wondering what is wrong with it, it has never done this before.

Any help or guidance would be grateful.

Many thanks

Answer:Computer will turn on but won't

Hi,

Try performing a checkdisk repair and fixing the master boot record. Boot the computer to your windows xp cd and follow the on-screen instructions. When you get to the main menu make sure to choose "R" for repair. Then the computer will take you to a black prompt screen which is the recovery console.

The computer will ask you to choose the operating system so I believe, choose #1 for c:windows. The computer will ask you to type in an administrator password but simply press enter to skip the process if you don't have an admin password.

Then type in "chkdsk /r" and make sure there is a space between "chkdsk" and "/r". This process should take about 1hr to 1hr 30min. After the checkdisk repair has been done, type in "fixmbr" to fix the master boot record. Then after that type in "fixboot". Fixmbr and fixboot should only take seconds. Restart the computer and see if your computer is able to boot up.

The computer is a Compaq Presario 5000. It has a Pentium 4 and windows XP installed on it. Im not any sort of computer-wiz but i do know a little about electronics. A couple months ago, my friend tried to install a wireless card into the tower. after that, she said the monitor wouldnt turn on. so i put off working on the computer for a while because i thought it was just a problem with the video card. well turns out there is more to this problem than i thought. for some reason, dont ask me why, she told me she had to take out the power supply. she dropped a screw in it. ohh man. and now, as soon as i plug the power supply into the wall, the computer tries to boot without me even pressing the on button. the hard drive lights blink as well as the power light on the front and also the cd drive blinks forever. the processor fan turns on as well as the power supply fan. the problem is, it doesnt sound like the hard drive is spinning at all and it sounds like the power is pulsing a bit.

sorry, i tried to describe the problem to the best of my knowledge so if you have any other questions just let me know. please help!
 

Answer:Computer Will Not Turn On! HELP!

a BIOS setting decides whether or not to automatically turn the system on when AC power is applied (it's a post-power failure setting).

I don't know how you drop a screw into a PSU... lol but you need to get it out so it doesn't cause a short circuit.

but anywho.. he's what you should do. You don't have to remove the mobo from the case (although that is the best way)...

1. unplug all power and data cables from the mobo and all other components
2. remove the CMOS battery and if equipped with one, set the CMOS jumper to clear
3. remove all RAM and PCI/video cards
---at this point there should be nothing but the CPU and HSF attached to the mobo---
4. blow out any dust from the RAM, PCI, and video card slots
5. re-install only 1 stick of RAM
6. re-install the video card (unless it's on-board video) and connect to monitor
7. hook up the boot hard drive (no other hard drives, floppy drives, or optical drives)
8. put the CMOS jumper back into it's normal position and re-install CMOS battery
9. plug the ATX power cable into the mobo (and the 4 pin CPU connector)
---at this point everything else should be un-installed or disconnected---
10. plug AC power cord in and attempt to boot up

...let us know what happens

This is freaky. I have a computer that won't turn off. It runs Windows XP. So you do your start turn off computer thing, and windows shuts down and the whole thing turns off.

But then, anywhere from 10- 30 seconds later, it turns back on by itself!

What the heck could be going on?

Hellow guys, i'm also currently have an issues where, when i switch on the main switch, the computer turn on itself, i didnt even press the power button! And after a few second, maybe 2 to 3 or 4, it turn off itself again. When i press the power button myself, there is no more power. I cant turn it on.

So, i do the same thing again. This time I switch off the main switch and turn it back on and the same thing happen again, the computer turn on and off again, and i also cannot switch on the computer after that. The same thing happen the next few time, so i assume there is something wrong with the hardware, or something loose? Any idea anyone?

And, to be more specific, when i turn off the main switch and turn on immediatly, there is no power and the computer is not running. But if i wait for maybe a few minute after turn off the main switch and turn back on, it run itself, the same process as i mention above. So is it weird? Hardware problem?

Answer:Computer turn on and off itself? Help

did it just start doing this out of the blue? Did you do something before this started?

The first thing I'd check is the power button on the case, as you say it does not work and if it's jammed on the ON it could give similar issues.
Open the case and remove the power button connector from the motherboard's pins, and if you can install in its place the connector of the reset button. Both buttons are the same under the hood so it's not going to hurt the board.
Now try using the reset button as if it was the power on/off button.

I have a second computer which has a 478 chip,video card etc. For a longtime I have noticed when I go to and run pcpitstop it says my video card is performing badly...56 pixel while the average is 124.

Recently it wouldn't start properly and my monitor would flicker and die so I changed the monitor but got the same problem.

I had already changed my power supply so I took it back and asked if they would check my video card.

They said they had found a problem with my motherboard and solved the problem.

Although it starts up ok initially, after about 15 minutes it blacks out .

However the thing is still going even when I try to turn it off with the switch.

If I hold the switch in, it does go off after about 15 seconds, but when I let it go it immediately starts again but nothing appears on the screen. Eventually I get it going again and it boots up perfectly only to crash again within 10 to 15 minutes.

Video card is a nvidea 9700 GT driver is right up to date as are my other drivers.

Answer:Computer won't turn on

Boot up failure

There are many reasons that could cause this problem. It could be a faulty power switch, solution, find where the power switch connects to your motherboard and trip the two pins with a screwdriver. Your motherboard could be grounding out somewhere. In that case you can take everything out of your computer, set it all up outside the case and try it then. It could be the motherboard which means you would have to replace it. Try those things and get back to me if it still does not turn on.
