No Power to keyboard, mouse or monitor

edited Dec 2011 in PC Building
This morning I woke up, the picture I was working on was up on the screen and no mouse. Frozen... so I unplugged and now I have no power to monitor, no power to mouse or to keyboard, yet I get all the startup action on my tower.. lights etc. I tried a remote login to see if I showed as online.. but it says I am not.

Any ideas?? I have a ton of images on that computer, I am a professional photographer and I am one step away from major panic here...

Thanks in advance

I am on my secondary computer now... waiting... trying to phone all the tech ppl I know, but you guys are the pros.

    Power off to everything.
    Turn the monitor on, now turn the computer on.
    You get power and drive lights right?
    Do you get any 'beeps'?
    Does your monitor think that it is getting a signal?
    You may need to slave your hard drive into another machine to retrieve you pictures.

    It sounds like you may have mobo issues. How good are you with hardware work?
    This could take some trouble shooting.

    Thanks for the reply, I am not good with hardware, when I do all that I still get fans turning, light on mobo comes on, but monitor sees nothing, mouse does not recieve power and neither does keyboard. I have reseated everything and that about uses up my hardware ability... pathetic, I know. So off we go this morning so I can beg my computer supplier to save my sorry a$$ because I have no clue how to fix it and I have two weddings on my HD that seriously need saving... I think I backed them up on my external two days ago though... we'll see.

    Thanks anyway, I will post the answer to my problems when I find out, just to help anyone else with this problem.

    My desktop did a similar thing a few months back, but bleeped intermitantly(possibly spelt wrong) I switched the power supply off, unpluged it, waited about 5 mins pluged it back in and switched it back on then held the on/off button for about 5 secs. It reset and had no probs since. It worked for me but doesn't mean it will work on any other computer! Worth a try though.

    I have a similar problem: when I turn the PC on, hard disk is working, no power to monitor (does'nt turn green), no power to keyboard, and probably no power to mouse too. I don't hear beeping sound. Is this a motherboard issue? I'm thinking of buying a motherboard if I can confirm that this has something to do with the motherboard. Appreciate any help. Thanks.

    With what your describing it could be mobo, PSU etc. have you changed anything recently? Can you tell if your fans are spinning up?

    Could you also list your system specs?
  • edited Jan 2006
    I didn't change anything, nor did I move it. It was working fine when it just powered off by itself and couldn't power it back on ever since. Fans are spinning up. I can open/close the cd rom. I tried changing the battery on
    the motherboard but it has no effect at all.

    It's a Compaq presario 5000, with Windows Me and Intel Penitum III. No idea on the RAM and hard disk specs though.

    I have an identical issue. Would you mind guiding me in narrowing down if the motherboard is trash or cpu or ... ? Current status: I have an ASUS P5LD2-VM motherboard and for some reason when I went to turn it on the other day, nothing seemed to function. After verifying all connections, I replaced the power supply with a ThermalTake 600, more than enough power. CPU fan spins, hard drive spins, green light on motherboard lights. But, no beeps and no power to keyboard or monitor. I have reset the CMOS as direced in the manual. - no difference. What is the next logical test to narrow down motherboard or cpu or ...? Thank you

    Well, you need a duplicate system just about to test if it's the CPU or Motherboard.

    I can give you one way to find out if it's the CPU or not. IF the fans stay spinning, it's not the CPU.
  • edited Jan 2008
    Since the fans continue to spin, I will assume that it is just the mobo. Thank you. Now I won't feel bad about ordering another mobo without cpu. Thanks again.

    Hi, everyone I have the almost extact problem as all of you but I have replaced my mobo and I still get no power signal to monitor and no power to keyboard, mouse. I have been trying to fix this for about a month now off and on, on my own and still no luck anyone got any ideas that I have missed to try. I get a green light on the motherboard, all fans come on, sounds like it power ups all right but I get nothing of a beep code can't remember if I supposed to.

    What I have tried is reseting everything, taking everything out and puting back in, tried using monitor, keyboard, mouse on other systems they work fine. Also tried using video card on another comp worked fine, tried powering the system on/off several times to no affect. I have tried different power supplies still nothing. I have even tried puting parts in piece by piece and powering it up still nothing on monitor, keyboard, mouse, I hope I gave you all enough info on whats going on with it. Please anyone help me

    hi, i know this is an old thread, but it is one of the first that showed up when i searched for a solution.. i had the same problem as the ones above - no response from monitor, mouse or keyboard.

    This is what worked for me
    I had 8 gb ram installed - 4x 2gb, i removed 2 of the bricks and tried to boot and it worked. then just put the others back in. and boot again - try it, mabe it works for you too :)

    Hi all, it seems that i have had a similar problem, I took the time earlier today and cleaned the interior of my PC. After powering it up, I noticed that there was no supply of power to the mouse and keyboard, also the monitor displayed that it was not receiving a signal from the video card. There was NO beeping of the motherboard that is common with detecting problems. My initial response was to check the the exterior and interior connections, when they checked out I turned to the net. I came across Matsg's post and followed his suggestion, removing my ram from the PC and starting it up. The mobo was now giving out the troubled beeping, I reinserted the ram and the PC started flawlessly. Thanks for the helpful advice Matsg and hope this will help others

    I'm experiencing a similar problem. I tried to install a dvd rw drive to a system that I had received from a friend. After installing the dvd drive and powering on the pc, I had received the following messgae from Windows XP: "Incompatible ATAPI device"
    I had pressed [OK] then decided to restart the pc. After restarting the pc, the monitor screen was black and the power light was yellow.

    My system has been this way ever since the attempted installation. I have noticed that there is no keyboard or mouse and the screen is black. The fans work and all of the lights on the mobo are green. I cannot seem to solve this problem. I just tried to remove the RAM sticks and boot as suggested above and I the mobo beeped. I reinstalled the sticks and booted the pc but still there is no keyboard, mouse or monitor.

    Any suggestions?

    Check all of your power connections, unplug the drive, see if it resolves. If it does, there is something wrong with the drive or your PSU/grounding.

    I had followed the same steps as stated in the above statement and found the the computer would in fact start up correctly again but with only the orginal ram blocks being used. Now the tower starts up as normal but have lost 2gb of ram. Is it anyone's thought that the ram blocks went bad all at once or is it an underlying problem causing this action. I have hammer and screwdriver ready to go to work on it. Thanks Lots for any Help!

    WORKED FOR ME #3


    Same problem, no monitor, mouse, keyboard or any other peripherals. Tried many cold starts and tinkering with wires. Then I removed 2 sticks of ram of my 4 total (2gbx4 sticks) and the computer fired up just fine...Not very happy about loosing 4Gb of RAM as I use this computer for gaming so I am going to perform shutdown and try installing the sticks again.


    UPDATE: BEST COMPUTER PROBLEM I've probably had, I learned something out of it and didn't have to replace any parts!


    MOBO had me worried for a few seconds but I replaced the same RAM in the same location and fired up the machine and all is working as it should in great condition! YAY!
  • edited Sep 2011
    I've been having this issue for the last 2 months. Unfortunately, I've been so busy, any tinkering I can do is sporadic. I think when I get home tonight I'll try booting my PC with no DIMMS in it, then seat them in one at a time.

    My PC:

    ASUS P6T Deluxe
    i7 940
    EVGA GTX 480
    Corsair 1000w psu
    Corsair 6G (2x3) 1333MHz

    I hope this works because I've been without gaming on my PC for too long. :(

    Check the specs of the mobo. Is poss that one of the two banks of slots may take different ram from the other, or I have noticed on some boards to run all four slots 1 & 2 can be DS (double sided) and 3 & 4 need to be SS or some other such combo.

    I have literally never heard of a motherboard that you are supposed to use "different" RAM in different slots, but if you have an example, I'd be glad to see it. More than likely he either had a stick go bad/damaged it or the stick isn't in all the way. It is "easy" to damage RAM when poking around your PC "cleaning" ... who knows what was being used to clean, etc.

    I was recently given a computer. Gigabyte GA- 7N400 Pro 2 motherboard with AMD Athlon CPU. Had 430w power supply but swapped for 350w from another comp. Had variety of cards : SPDIF, TV, etc. Has no onboard graphics so have installed Geforce FX5200 so can attach monitor. Had no Ram so put in 2 x DDR 400 512mb as per mobo specs. Had no HDD and replaced a faulty DVD RW drive. Removed heatsink. cleaned and reset with new ArcticSilver 5. Cleared CMOS and Bios. Have detached all PCI cards except FX5200. When power on fans run so CPU is good. There are no beeps. Have usb optical mouse which lights up but no keyboard, either usb or ps2, and no monitor so can't access bios. Have tried the ramless boot but no luck. If perhaps this thread is still running does anyone have a suggestion please?

    Your PSU should be adequate, assuming it is known good. The mobo should have an AGP connection on it, but you may not have that ancient cable :D . The fans spinning up do not necessarily indicate a good CPU.

    The most important part I saw in your post was the lack of beeps, which can mean a bad mobo, especially if you get no beeps with either CPU or RAM not in the board. How do you plan on accessing the computer without a monitor for at least initial setup?

    Thanks for the reply. As far as the beeps go, I get no beeps with or without ram installed. If I remove CPU I get loud buzz and power switches off. The ATX power supply works but showed low voltage (2.89) on the 3.3v in bios on computer it came from but still ran. Aside from ps2 x 2, USB x 4 and Ethernet as well as usual audio connectors the only other available ports are an LPT and 2 x 9pin serial. Would the onboard AGP connector be one of those please? The other odd thing about this board is it is Dual Bios (has 2 bios chips). I only assumed that fan spinning means CPU works because someone stated that earlier in this thread but logic suggests that only indicates power getting to the board.

    Well, power supplies can go partly bad, or weaken so that they go to low voltage, and underpowered power supplies can also undervoltage motherboards and RAM and other things like video cards. That can hide the problem with a set of other things looking like they are bad (they could be bad, but PSU is likely also to be bad or damaged inside).

    The PSU I would replace with a new one as a try at fixing - many times with many computers things have been fixed with a new power supply after a surge got to it and it gracefully partly died rather then surging other stuff.

    Thanks John. I know the power supply to be faulty. The computer it came from was crashing periodically and the 3.3voltage in CMOS was showing low and there are no more crashes after I replaced it. I was hoping it would at least boot this machine as I don't currently have a spare PSU. I'll shelve it until I can get another and then try again. Thanks for the help. This has been the most responsive forum I have joined and I'll be back with any future issues I have. Thanks again.

    Houston, we have liftoff. I was about to pack up and leave the machine until I could replace the PSU when I thought I'd give it one last shot. I thought perhaps there might be a device trying to draw off the faulty 3.3voltage suplly and if I disconnected any unnecessary devices it might work. The only cards that I had left in aside from the graphics card were a modem card and a 3 port USB 2 card. I removed those and voila it boots up. Am now loading an OS onto drive and will eventually replace the PSU. Needless to say, this makes me very happy.

    The metal box is a case in computer-speak. The video card might have been loose in the place it goes into (socket), or dusty and then being overheating real quick(which would make it turn off), or bad.

    I'm currently having this issue. I just moved my computer from my old apartment to my new apartment and before i packed it up i cleaned up the CPU a bit it was clogged with all this dust.

    Right now my computer doesnt have power to the keyboard and mouse and i have no functioning monitor (both monitors have power). Fans are running. No beep sounds when i turn it on.

    I tried to unplug all the ram 4x1024 corsair ddr2's and turned it on but it still doesnt work.
    tried replugging power and all.

    Try this: careully remove the Battery, keep it out for 30 seconds to a minute, put back in. Then see if it starts. If not, read motherboard manual to find out what jumper needs to be set.

    Why: some motherboards come with a jumper block (little thing that connects two pins) disconnected, so the BIOS is not enabled (then computer will not start up or show video at all, no power to run the Setup program automatically that adjusts settings for stuff and then lets computer start up). Some come with tape on CMOS battery that needs to be removed. Please tell us if this does not work at all.

    Hi squeeze me, It's possible that when you cleaned the dust from the CPU you may have loosened a connection inside the case. Check all connections and make sure all cards are seated correctly. If you removed the heatsink to clean it then you may need to reseat the heatsink with new thermal paste. Generally speaking if the heatsink is not seated correctly then you'll get a loud buzzing sound when you try to boot.

    As a tip I use a small electric compressor (can buy for about $10) with a needle valve attached (used to pump up footballs). This way I can get inside the fins to blow the dust out. Especially useful on laptops and avoid having to take them apart.

    Hope this helps.

    I have an ASUS P5VDC motherboard which requires a jumper to be set depending on whether you are using a 4x or 8x graphics card. May be worth looking at. Also, if there is an onboard agp, connect the monitor there and remove ALL pci cards. If it boots then reconnect the cards one at a time starting with the gfx and you can find out which is causing the issue. I had exactly the same issue with a GA-N7400 mobo. It didn't have any onboard agp so had to leave the gfx card in, but when i removed the ethernet card and a multi port usb 2 card, the machine booted up. I was able to later reinstall an ethernet card and all has been fine since. Also if you get it to boot as far as the Bios settings hit the default settings. Also try resetting the cmos. Assuming the mm keyboard is usb, try it in a different slot. Or go back to the old keyboard. Hope some of this is usefull.

    hiya, thanx for the reply, but it only had 1 card in, and that was gfx card,, but i tried that in diff pc and that was ok there, i did a soft build, with just hard disk in for start, and nothing still, i will try removing the litle lithium battery as i heard thats 1 way of resetting bios to defaults,, other than that i havent got a clue, weird that all i did was plug a new usb keyboard in and this happened, im quite good with pcs anyway so i know i have all my data safe, and if i really have to will build another pc, jst that i really liked this 1 and im confused as to why this would happen,, its been running great for well over a year, and i look after it,, another help on the matter would be really appreciated, thanx again for the reply,,

    Ok, weird old question-- even some modern BIOSs still have this quirk with USB cards (and not built-in USB sometimes):

    When you get video, can you try enabling Legacy USB? in your BIOS Do you then, after powering down and inserting card, get video?
  • hi guys, thanx for all support here, but ive fixed rhis prob now,, i took out lithium battery, left if for half hour,, stripped it right down to bare bones, plugged battery back in, and reconnected parts 1 by 1 until i finally heard bios beeps, luckily didnt take long as i only had hard disk, dvd rom, and gfx card to plug in 1 by 1, but glad to say its all workin again, then was just a case of updating info in bios and few settings here n there, but was well worth the few odd mins,, thanx sooo much for help,, if any1 has same prob, thats what i did to solve my prob, so may work for any1 elses,, cheers again guys,, im a mooocho happy man again, lol
  • Hey i had the same problem with my hp desktop. my computer was down for a year due to a bad power supply. i replaced my power supply. then it powered on, fans running,cd drive running. but i had no connection to monitor n no power to mouse or keyboard. I then replaced that little round lithium battery that is on the motherboard n it started up!!!! The first screen was a recovery screen n i got all my old files back.

    You should check your RAM with Memtest86+ while it is installed. Also try flipping their locations into different slots and see if the issue persists/follows a stick.
