All in one computer won't turn on

Question: All in one computer won't turn on

HP 19 All IN ONE PRODUCT NO. G4B06AA#ABAMOD NO. 19-2113w I have a all in one desktop computer for my business. Probably not the best one to have for the job, but it works! Until we put it to sleep one night. Came in the following day moved the mouse to wake up and nothing happened. So I unplugged it held the power button for 30 sec to drain the power and do a clean reset but still nothing. However- the back light comes on when plugged in, the top power button comes on and when I do pushthe power button I can hear the fan come on as well as the hard drive work. But agin nothing else power/lights to mouse or keyboard lights to the Ethernet port even back to my switch! I've since bough a new computer but would like to get this computer back up and going just for the hell of it! Anyone out there know what's going on with it?

Preferred Solution: All in one computer won't turn 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 (This link will automatically start a download of Reimage that you can save to your computer.)

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?

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.

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.

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.

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.

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.

I am having trouble with a 6 month old IBM R51 laptop - when I select TURN OFF COMPUTER from within Windows and the START button - the computer sometimes hangs and will not shut down. I have to press the power button to reset. Any idea what could be causing this?


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.

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.

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.

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?

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?

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.

Okay well my computer has been taking an age to start up for a while now but no matter what I searched for I never found anyone with a similar problem on other forums and thus could never find an answer. I can't really afford to go get it repaired right now so I've just been living with it for months; essentially I get the initial splash screen, the windows loading screen and then blackness for ages! Sometimes the screen is black for a good six to eight minutes, then a little cursor appears in the centre and I'm brought to the screen where I can pick which user I want to log in to. From there it's all fine.

Ever so often though, the computer just hangs at the black screen forever, so I have to power it down with a hard reset, then restart and a menu comes up after the initial splash screen asking if I want to run startup repair. Whenever I do that it seems to get me back working again (still with a very long boot time) but it will uninstall either Google Chrome or ITunes. I don't think it's because either program is the problem, I think it's just cause the updates get corrupted when I use the restore manager to reset back to a prevous working state of my computer. Either way, I re-install them and they soon work fine and dandy. My problem is now that the computer won't turn on at all. The black screen holds forever and the startup repair manager says this is a problem it can't fix and simply sends stats to Microsoft.

Hello! Recently, I experienced a storm and my power went out for a good almost 17 hours. At the time my power went out, my computer was shut down. When my power came back on, I went to go turn it on but nothing happened. It's plugged in and there's a tiny green light at the back that's solid on.

I have an HP TouchSmart 300 PC. Which I'm not a computer expert or anything, but that probably means it's old - which it is. The computer and monitor are built into one. I unscrewed the back of it to take a peek and there's no physical damage that would suggest that it's been fried, but I know that's not always the case.

I tested the outlet with other devices and it's completely fine. I'm mostly certain that it's my computer.

Currently, it's unplugged and I'm just letting it sit, hoping that it'll somehow be resolved by time.

What should I do? Any expert advice? Thanks!

I have connected everything, the stand offs on the p35 ds3p the fan, with thermal paste, the 8600gt, the drives, and all the plugs, with the power supply. after pushing the power button, it flashes on for about 1 second, the fan in the supply moves slightly, and then it stops. its happened about 3 times now. what could be the problem? could it be a faulty power supply? do the wires touching the case cause a short? or is that negligent? also, could it be the motherboard being shhorted? thanks for any help...

Hello everyone. Ok, here is the deal.... Today a bad storm started rolling in, so I shut down my computer and unplugged the surge protector from the wall.

After running into town and back (approx 1.5 hours) I plugged everything back in, and my computer would not start. EVERYTHING else plugged into the surge protector powers on: speakers, monitor, router and hub, external HD, desk fan, everything except my computer powers on. The only thing that is on is a little green light on the motherboard.

I have tried the following:

Flipping the reset switch on the power strip

Flipping the power supply switch on and off

Reseading various hardware

Checked, rechecked, and rechecked any / all cables inside and outside of the computer

Unpluged the computer's power cable from the surge protector and plugged it directly into the wall.

Nothing is working.

Now, I did not unplug the ethernet cable from the computer, but if it had been hit by lightening, wouldn't the cable modem, hub, or heck even a TV have gotten fried?

The only things I can think of doing is A) Buying a new power supply, or B) a new motherboard. What do you guys think? Please help, this is just super frustrating....I have a two thousand dollar footrest.

Here is what happened. I was plugging in all the cords in the computer and turned on the power. Then I pushed the computer in under my desk ( the computer is on a carpet floor). As I pushed it in, I saw a spark from the back of the computer and the computer turned off. Now I cant turn on the computer anymore. I mean nothing happen, like there is no power at all or anything. I mean if the video card is burnt, you still be able to turn the cpu on and see some kind of power right? But in my case, there is no sign of power.

So Im wondering what could it be. It seems like the power supply is messed up but Im not sure. If anyone can help me please reply. Im greatly appreciated. Thank You

I turned the computer off and when I turned back on I got nothing. I unhooked all my cables and tried again. Thinking it may be my moniter I brought the pc home and tried. Now when I plug it in and turn it on the lights come on, the fan starts to run and then a couple of seconds later it shuts down. Just like you unpluded it.
Any ideas?

Answer:My Computer will not turn on

Time to start troubleshooting, and, given this may be very valuable info, you might want to take it to a shop.
1. Check the outlet at work. If it starts at home it should start at work. Maybe it cooled off by the time you got home.
2.This could be a power supply or a heat issue. Clean out any dust/dirt and get the PS tested.
3.If you don't have a backup plan, now is the time to get one and implement it.

recently, i had my PSU literally blown up.
i hooked it up, and it started i dunno, i guess blowing up is the best word to describe it.

So, afterwards, (it was a 650 Cooler Master PSU) i got a 250W PSU and plugged it in.
the light in the mobo turns on, the little green electricity indicator, but the computer wont turn on.
i press the power button a million times, but it wont turn on, no light will turn on, no fan will turn, no little electricity sounds... nothing.

So, what is it? i dont think my mobo or anything else on my pc was fried, so can it be that the new 250w PSU isnt comptaible with my pc?

I have a Radeon HD4670 512 Vram, m2n4-SLI mobo, an athlon 64 x2 5200+, 2 HDs 1 is 80 gb and one is 300 gb, and two 1gb ram sticks.

This problem is completely baffling me. Any help with this would be greatly appreciated.

Here's what's happening. When I switch the power supply on, leaving the off position, the computer instantly comes on, regardless of the on/off state it was in before. The fans all come on, the GPU fan is at full blast (I've never seen it on so high). And it will remain to stay like this appearing to do nothing, appearing to be "locked". And then, if the power button on the front of the computer is pressed the fans go back to normal, and the computer sounds as if it's booting a normal boot.

Then most recently, after trying to debug this problem for a while, if after being in this "locked idle 'on' state", the power button on the front is pressed and the computer starts "booting", the mother board's speaker starts beeping. 3 long beeps, a pause, then a continuous repeating long beep.

What I've done to debug this is take out then video card, switch on power supply. This results in the computer instantly turning on into this locked state. Then I tried taking out the RAM, switch on the power supply. Locked 'on' state. Take out every single other device, keyboard, mouse, all SATA ports, and miscellaneous PCI cards. Power supply on. Locked 'on' state. And all leads to the same thing happening after the power button on the front is pressed.

So after not using it for close to a year (moved a couple times and have just stuck to my laptop) I can't get my desktop to power on.

The best I can get from it is that the lights on the front of the tower turn on as well as the fans for maybe a second, probably less. I can only get this to happen once and then nothing, unless I unplug the power and plug it back in.

I have checked all the chords from the PS and they all look good, there is a green light on the motherboard that is always on unless I unplug the main power cable that runs from the PS the the MoBo. Its not throwing any error beeps or anything.

I am at a loss at this point. Any help would be appreciated.

My computer won't start, and this is why I'm posting today. My computer worked fine up until this one night it stormed and the roof leaked. It didn't seem to touch my computer (the water), it didn't seem anywhere near it or inside of it from what I've observed. So, the rainy night "could" be coincidence, I hope.The gist: ever since that night it hasn't worked.I've noticed some things that do work still like the Cooler Master fan works, and tends to be incredibly fast, loud and cold. The "on" button won't illuminate when I go to start for some reason at all. The CD disk drive opens and works, and the monitor works fine ???? I think, according to the fact it lights up and (notifies me on screen) as it goes into Power Saving Mode. The green light in the back of the computer by the other fan seems to light up (I'm assuming that is good?)Could it just be a dust problem? Besides the fact my monitor is LG, everything that came with the computer is still intact.Please help, thank you! P.S if you need more information, let me know. I'm sorry if this is somewhat confusing. Or maybe it's easy, I just genuinely don't get this.

I fear that I've done something extremely stupid to the CPU. The CPU cooling fan has been extremely noisy, so I was wanting to change it. I'm living in Kenya and finding a fan to replace it was not as easy as in the USA.

Someone suggested using WD40 on the fan. So I removed the fan (No I didn't spray WD40 inside the computer!). Wiped the fan dry and allowed it to sit for a few hours. Then I connected the fan to the MB (only the electric connection, I didn't put the heat sink or fan on the CPU) and covered the fan in a paper towel to catch any WD40 that might spray out. I turned the computer on for maybe 30-60 seconds maximum to allow the fan to spin. The computer shut itself down. It never did begin to boot. It gave me an odd one line message that I can't remember. It seemed to mention something about pooling.

Now it won't restart at all. Sometimes when I push the on switch, it lights up briefly and the internal fans begin to spin, but for 1-2 seconds is all. Then nothing as if there is no current. I've checked all the electrical connections, the UPS, etc.

Could I have ruined the CPU? Any other possible sources of this problem?

Answer:Computer won't turn on - CPU?

Um, well i can say unless you ran it for hours you shouldnt have damaged the cpu. I acidentally ran a P4 for 1 1/2 hrs with the fan off because of a bad fan port on the mobo didnt hurt it just really bad performance. Try clearing the CMOS by pulling the battery or moving the jumper that is around the battery over and back.

and wd40 attracts dust its like a film of dust grabbiness, i put it on my ceiling fan to see if it worked and it attracts dust...

But when I pushed the power button to turn it back on, nothing happened. No lights turned on, no fans or anything. I then unplugged everything and opened up the case. I plugged the power supply back in, and tried powering agian. Agian nothing happened. The only light that was on was the standby powerlight on the motherboard.
My intitial reaction is that it's a power supply failure, or a power on switch failure. However looking through some other posts on similar problems says there is a chance it is a motherboard issue.

The other day I had a very quick power cut in my home. My computer was turned on at the time and obviously when the power cut out the computer went off. When the power came back on I attempted to turn my computer back on with no success. I tried unplugging everything and plugging it back in, and tried turning it on again still with no success. I thought that the fuse might have gone in the plug but the monitor is stiull receiving power, and as this is connected to the power source through the tower I assume the plug is working fine! Does anybody have any ideas what the problem is and how I can fix it? Even if you can give me and idea of what to look for when I take the side off and have a look at my motherboard. I'm at a bit of a loss at the moment. Thanks again everyone. p.s. Im rubbish at knowing what technical info I should include so give me a shout for more info on this.

Answer:Can't Turn Computer On

The power is not reaching the Mother Board. Hence, i guess that means either the power supply of the tower has broken or the Mother Board is damaged. I would first test it by replacing the power supply unit. (you can borrow ....). If you are lucky & it works, you can buy a new power supply unit. Else, u could be in trouble as the MBoard might be damaged.

I got out my old PC because I need a file on it and I set it up and it won't turn on. Where should I look to try and fix it? Any suggestions?

Answer:Computer won't turn on

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.

My resolution is turned to the lowest. I'm not sure exactly why, is it an issue?

My video card failed not long ago, I replaced it (Nvidia 9800 GT) and when it failed one of the symptoms of it was the resolution turning low, but there were a lot of other symptoms and I haven't experienced them.

Does anyone have an idea why this is occuring?

My drivers are up to date, on Windows Vista, it's a Gateway computer.

Thank you for any help you might be able to give me,

I just assembled a system on Tuesday for a friend. It's an Athlon X2 3800+, 2GB DDR2 800, and a single Geforce 7900 GS. Today, it was left running for a while and went into sleep mode. It would not turn back on. So he pulled the cord to the power supply and plugged it back in and now it does nothing when the power button is pushed, no PSU fan or case fans or lights or anything. I figure either the power supply is bad or the signal is not getting from the power button on the case to the power supply.

A couple of thoughts... Maybe the power supply that came with the case could not handle the 7900 GS; might be helpful to know that 3DMark was running at one point (we did use the computer under a load for a short time), and when the computer stopped working, it was not under a load. The PSU is rated at 400w; the video card recommends 450w (500w for SLI). The power supply, however, has two 12V lines wtih 20A on each. The combined rating says 25A. (Pretty good I thought for a power supply that comes with a case.) One of the newegg reviewers for the 7900 GS said the following:

"I have this baby in a Shuttle SK22G2B XPC, which only has a 240 watt ps. People, please do some research and don't assume half these kids know what their talking about. Don't let the two additional molex connectors needed to run this baby scare you into buying a gazillion watt power supply. A solid 350 watt ps from a reputable manufacturer should be sufficient." (Is this true?)

It all started with my motherboard not picking up any IDE drives, so i turned the pc off, took all ide cables out and stuck them back in, and the pc began to boot and i had windows loaded. After restarting it, the motherboard told me no IDE drives were being detected again. So i shut the pc down... done the same thing, this time around though, nothing will boot/power up.

If i take the bios battery out for 5 minutes or so, the entire computer will have power running to it as soon as i put the plug into the back of the powersupply, this is without pressing the power button on the front, all fans and mobo lights are up, but the PC will not turn off unless i flick the PSU switch or simply unplug it, after doing this though it wont power up normally.

I guess this is a problem with the motherboard and will probably need replacing, i just want to really be sure this is the case before ordering new parts.

Answer:Computer won't turn on, help

You do not need to replace the motherboard, but you have work to do.
First, we need the brand and model of computer, brand and age of hard drive, and other details about your system... OS, power supply, memory, age of components.
Did the failure to detect the hard drive happen suddenly? What antivirus and antispyware programs are you using. It appears you have some infestations or corruption that needs attention.
Have you tried replacing your cables?
As I understand your message, you have two issues: Your hard drive is not detected, and your computer will not turn off when asked to do so by Shut down in Windows.

I go to turn it on, the fans start up and the computer seems asif it's going to boot for 6 seconds, then for 4 seconds it stops and tries again... It repeats this process over and over. It also makes a clicking noise which i don't know where is from whilst it is trying to boot.

I think my PSU might have just broke but i'm really not sure. I haven't added anything to the computer for it to need more power. One thing i WAS thinking was that, i filled up my hard drive, but even when it was full i had turned it off and on and it worked, just 24hours after that... Is the problem likely to be a PSU because i don't want to buy one and not be able a refund?

Help me please as i'm really needing my computer back to apply for jobs and other research.

My computer was working until I moved, when a dent on the front left side appeared. At first I could get the comp to turn on but nothing would happen, no startup sequence at all, just a black screen. Now the power won't even come on. Hopefully someone will have a suggestion on how to fix this, other than hiring a diagnostics guy because that's the obvious ultimatum.

Alright, alright.. this happened to me once before.. although it wasnt exactly the same situation.Im not 100% sure why this happens, but sometimes plugging a device into the USB can cause it to completely lock up (freeze), after wich u can only close it via the reset button on the front, or in extreme cases the power cable on the back.Now, when this happened to me the first time, i thought it was something faulty with Windows so i have it installed again. However the problem came back, somehow the PC would totally freeze every time i plugged in that device. The only thing that does not overlap, is that u say ur PC does not turn on. Mine turned on but then froze again after only a little while.You say that ur PC DOES turn on, but the monitor dosent display anything. Does this mean that the monitor displays the "no signal" colorful hovering box, or is the monitor competely turned off and not even displaying the orange light next to it's power button. As in, is there no difference beetween when its ON or OFF?The PC working but the monitor staying blank (ON, as in the light near the power button is working.. but u DONT get the "no signal" box, as in its just black and nothing else) means that there is probably something wrong with ur graphics card. If there IS "no signal" then its probably not ur graphics card but some bigger problem.Can u answer my questions, and also get another monitor to test with this PC in order to see wich one is fualty?If ur ...

I see there have been a couple posts like this, but thought I would personalize it.

To start, on my old comp I had problems with it turning back on when I turned it off. It would just come back on by itself.

Then one day it suddenly shut down, and would not turn on. When I tried to turn it on, it made a litle noise (would later discover it was the noise of fans turning on for a split second) but nothing else.

I figured it was old and I wanted to update anyway so I didnt care.

I went and bought a new motherboard, graphics card, processor, new RAM and a new power supply.

They were:

GIGABYTE GA-G33M-DS2R LGA 775 Intel G33 Micro ATX Intel Motherboard

APEVIA ATX-AS520W-BK ATX 520W Power Supply 115/230 V CB IEC 950/ TUV EN 60950/ UL 1950/ CSA 950

Intel Core 2 Duo E6700 Conroe 2.66GHz 4M shared L2 Cache LGA 775 Processor

GeForce 8800 GTX

And Kingston ValueRAM 2GB (2 x 1GB) 240-Pin DDR2 SDRAM DDR2 800 (PC2 6400) Dual Channel Kit Desktop Memory

I installed everything into my old case.

When I turned it on the processor fan spun, fan on the power supply spun, and fan on the side cover spun for a second, then shut off.

I switched outlets and when I turned it on again, suddenly the processor fan and power supply fan both turned on and stayed on. However, the processor made a high pitched continuous noise.

I turned it off. I noticed the fan was a little loose from the motherboard so I tightened it and turned it on again. Again it turned on... Read more

Answer:New computer will not turn on

Even tho' 520w PSU should be enough, it may not have the needed amps on the 12v rail(s) to fire up the mobo.... hopefully that's all it is. My other thought is that maybe the heat sink on the CPU wasn't seated correctly and the CPU may have been thermally damaged. I know it doesn't seem possible that a CPU can reach critical temps that fast, but a friend burned up on old Duron 800 by turning on the PC for about 3 seconds without a heatsink; "I was testing my RAM and just wanted to see if would POST and didn't think I needed the heat sink..." - famous last words Double check everything: the RAM, video card, CPU, all power connections and data cables. Be sure everything is seated firmly. Maybe take the mobo out of the case and see if it powers up "on the bench". Maybe something in the case is grounding it.

Should I try and return my PSU? Any help is appreciated.

Answer:Computer does not turn on

Have you attempted to overclock anything (CPU or GPU)? If you are improperly overclocking, it could cause issues.
Just like mentioned in the other forum, you should look at getting at least 2 fans into your case. One in the lower front to intake air, and one in the back (by the cpu / power supply) to exhaust air. There are arrows on the sides of the fans to show you which way the air flows through the fans, so make sure you pay attention to that when installing. Without knowing for sure (would need to know what kind of computer case you have), I believe you could put two 120mm fans inside. Once you know for sure that you have the fans installed correctly, I would test it and see if your problem persists.

I just bought ram for my computer. I checked everything and it is the correct ram.
What I did was, I turned off the computer. Installed the new ram. Turned on the computer.
What happens is. It turns on, then off for 3 seconds, then turns back on. The computer is running but nothing is showing on the monitor, and the mouse won't work, the keyboard etc. The light on the monitor is just blinking.

When I take out the new ram and add back the old one, my computer works fine.

My old ram is: DDR2 PC2-5200 (512MB)
New ram: DDR2 PC2-5300 (2GB)x2

I bought 2, 2gb rams.
Yes I already tried installing only 1 of the 2gb at a time. Also I tried using different slots. Nothing worked They are both 240 pins, they fit in the slots.

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.

On the rear of the tower next to the PSU plug you will see two switches. The RED one sets what voltage you need :110 if you are in the States.The second switch is a power switch and should be in the up positionNow try the switch on the front of the tower.Also plug something you know that works into the same outlet the tower is plugged into to make sure you have not tripped a breaker/fuse.patio.
