Sudden loss of keyboard/mouse input

Q: Sudden loss of keyboard/mouse input

Good day,

Everything on my computer was fine this morning when I left for week, but upon my return I noticed that my keyboard/mouse wasn't working. I restarted my computer and confirmed that my keyboard works in the bios and whatnot, but when I get to the windows login screen, I get no response from the keyboard or mouse.

The mouse is a simple USB one, and I'm using a PS/2 keyboard, so I doubt it's some sort of sudden driver issue.
I tried logging into safemode, and I get the same result, can't move my mouse or use my keyboard.

Does anyone have any idea how to possibly fix this issue? I'm unable to restore from an earlier state either.

Thanks in advance for the help.

Preferred Solution: Sudden loss of keyboard/mouse input

I recommend downloading and running DAP. It can help sort out any driver and firmware related issues on your system

It's worked out well for many of us in the past.

You can download it direct from this link http://downloaddap.org. (This link will open the download page of DAP so you can save a copy to your computer.)

A: Sudden loss of keyboard/mouse input

Do you have a Windows Disk? If so you can boot to that and choose the repair option instead of the install.
If you don't have a Windows disk, can try another mouse and keyboard. If another mouse and keyboard work then the keyboard and mouse drivers can be removed and windows will automatically reinstall them on boot.

Welcome to TSF,

Some details of your system, brand name, model, desktop or laptop, CPU, RAM, age of the system.
Which OS have you installed?

Did you reboot after plugging in your external keyboard. Is it a USB connection?

Try this link to see if any of the suggestions cover your issue.

kind regards,

So I am having computer problems :(.... basically my computer's performance is much lower than it has been in the past... i have been using it for about half a year and then all of the sudden performance dropped... I have never seen my cpu go over 60%... the performance loss is most noticable in startup and when playing audio because of the skipping.

I really would appreciate the help because i think it must be some kind of virus.

Read other 16 answers

when I boot the computer, I do not have access to the keyboard or mouse. System restore is turned off. THe keyboard works in the boot menu and in bios. bios shows the mouse and keyboard enabled. I tested the mouse on another system, and it worked fine. I also tested another mouse on this system and it failed to work in the same way. If I go to last good config in the boot menu, I can boot and have use of the keyboard but not the mouse. I cannot get into safe mode because it won't let me do a combination of last good boot and safe mode, so I cannot type anything in the login window. When I go to last good boot and navigate via keyboard to the device manager, there is no entry for the mouse. when I open the control panel and then open mouse properties and go to the hardware tab, it shows no driver and no mouse.

The fact that there seems to be a logic to this leads me to believe it is a virus or rootkit of some sort rather than a hardware problem.

ANy help getting my computer back would be greatly appreciated. Hoping to avoid a reformat.

I can log on correctly, and join games normally. However, after I click the join game button, and the select class and spawn point menu comes up, my keyboard and mouse stop working in Battlefield 2. I can alt-tab out normally, and my keyboard and mouse will continue to work outside of Battlefield, and player icons and control points continue to change on the selection menu, but I cannot move my mouse or keyboard to even exit to the main menu. I am at a complete loss for what to do.

A:No Keyboard or Mouse Input

I am currently experiencing a similar problem with the Demo version. I have previously been able to play with no problems, until recently. I had changed nothing in the menu's, nor changed my mouse/keyboard/joystick or any drivers.
Originally, i was having the exact same problem, so i tried an un-install/re-install to see if this would fix the problem, now however, i can use my keyboard, but my mouse still refuses to respond while trying to select a spawn point.
I am totally confused by this, as my mouse also works fine when i alt+tab out to desktop.

Any help will be greatly recieved,

hello & welcome to TSF ,

have you tried to use PS/2 devices( wired )

normally when you have probs with wireless devices it is best to go back to the default type (wired ) then go to the device manager and check to see if you have any driver issues then try reinstalling the software if your drivers are okay

So this issue started with my new build. Originally I was using a Logitech G19 keyboard and Logitech Performance MX mouse. After building the PC, I updated to the latest BIOS version. After installing Windows and during the numerous reboots when installing updates/patches, I noticed that sometimes as Windows was loading, my keyboard would not be lit and thus I could not enter my password into the login screen. A reboot or two would usually resolve the issue so I was just dealing with it.

Now, starting two weeks ago when I upgraded to a Razer BlackWidow Chroma keyboard and a Razer DeathAdder Chroma mouse, EVERY time that I boot, the keyboard/mouse will light when the PC is powered on and remain lit until Windows splash screen. Then, right before the login screen appears, the mouse and keyboard lights will go off and I will not be able to login to Windows (ie: keyboard and mouse do not function). However, if I move the mouse as the lights go out, the lights will come back on and both will remain operational.

As this occurs towards the end of Windows loading, I'm leaning towards this being a Windows issue. I've just never seen this before and have no idea how to fix it.

I can give the full hardware specs if needed (or you can check my system details to the left), although I don't see how other hardware would be a factor.

Hey everyone.

I hope this is the correct place for this kind of problem.

I would say, about two months or so ago, i starten having the problem where devices that are plugged in to the USB ports stopped responding.

Mouse went dead (Using the Logitech G9x, and the "sensitivity" light would start flashing)
Keyboard went dead
Headset sort of died, i still had sound, but i am unable to use voice.

Only solution was a "hard shutdown" of the computer.

The problem have been there since then, with an average crash every other day, and some days up to 3-4 times.

I'm not sure what other information i should add, but let me know and i will supply it.

Thanks in advance

p.s. Might also add that during this time i have also had quite a few randomly apearing BSOD

In the left hand window click on the+ for the individual device groupings and they will open out to the variouscomponents.

Goon opening out further until you get to the device itself. click on it and itwill highlight. In the right hand window there will be a very detaileddescription of that device as in brand, speeds model number etc etc These arevery detailed and are just what is needed for searching for drivers etc.

I am trying to reuse a old HP Compaq machine as a CCTV server using iSpy: Open Source Camera Security Software.

Whenever I boot up the machine, everything is normal, UNTIL I get to the (Windows 9x style) login page, when mouse and keyboard do not work.

The keyboard works fine in the BIOS, but the mouse can't be tested.

I have a Windows XP Home Edition Service Pack 1a CD.
The OS on the HP is Windows XP Professional Service Pack 3.

I am without broadband, using a dongle to rely on for internet, so ISOs and torrents are a big no no.

This is using a wireless keyboard and a wired mouse, both USB. As I said above, the keyboard works fine in the BIOS. Both keyboard and mouse work on a Windows 8.1 machine, so I know it is the computer's problem.
Any ideas? Thanks,

I'm having a problem with the interactions between the mouse and keyboard and the computer. When using the scroll wheel, the webpage that I'm viewing will begin to zoom in and out. Clicking the scroll wheel usually fixes the issue. Sometimes I will left click to open a shortcut and receive the properties box, so in order to open anything I have to right click and use the open option. Sometimes clicking on anything will result in the File option opening at the cursors location and refuse to leave, instead just flickering. Keyboard works for awhile and then refuses to respond correctly, opening dialog boxes, not responding, etc.

Reinstalled all drivers, rebooted system, cleaned the inside of the computer, tried other mice and keyboards all with the same effect.

A:Keyboard/Mouse Input Issue

Go into the mouse properties window and see if the scrolling wheel is set to "Universal Scroll"(or something like that) and not set to "Zoom".

I hope I'm not wasting your time here, as I'm not positive this is a virus/malware/keylogger/whatever issue, but I came here knowing you're all knowledgeable in this and hoping you could at least cross this as an issue off the list. Recently I've had issues (I've actually only played Borderlands and Dragon Age: Origins to test this) with my input being lagged or delayed, not sure how to put it. Basically, if I'm standing still looking around, everything is fine, however, when I start moving my character, once I release the button (whether it be the movement keys or the mouse button while looking around) it carries on for anywhere from 1 to 10 seconds. I've tried many different game/performance things, such as Vsync and Mouse Smoothing etc. Anyways, I'm STILL waiting on the RootRepeal to finish (boy this has taken all day), but I'm hoping the DDS may lead to something while I wait. Thanks in advance.

*EDIT* I added a HijackThis log for a bit more info until this RootRepeal is done.

I tried to search for a solution for this problem but i dont know how to word the query. So i restart my machine and every things going good video display and i can press del to get into the bios, i can move around in there and change whatever. Once vista loads the keyboard and mouse still are receiving power (lights are still on) but are non responsive. Ive tried reseting the cmos and puting everything back to defaults in the bios menu but to no avail. The weird thing is that it happened out of no where. It was working fine and my roommate (and i believe him) came home turned it on to find these problems. Its seems like all my onboard input/output connectors are not working.

Hi, this is my first post, apologies if anyone has posted a thread on this problem.

I've had a problem with Oblivion over the last month, and no amount of google-based research has helped. It was playing fine, but now after a few minutes into the game, the keyboard and mouse controls simply lockup and i cannot make input to the game. The video display and audio remain unaffected, i.e. NPCs continue to act as normal, music plays in background. The only way to regain system control is to CTRL-ALT-DEL out of the game.

I've tried reinstalling the game several times, have uninstalled all third-party audio/video codecs (divx, xvid, ffdshow, ac3), have reinstalled directx 9.0c, have latest video-card drivers, have set the game to lowest performance settings...all to no avail.

Please, any advice on fixing this problem would be hugely appreciated. Thanks.

My optical mouse (USB) that I've used since day one on my month-old computer in place of the supplied PS/2 mouse began to fail last night. I replaced it with the PS/2 model, and it worked fine. I put the computer into hibernation, bumped the mouse as I got up, and it returned from hibernation. Weird. After checking all the background processes and power options and finding nothing new or unusual, tried a System Restore, with no change. I hooked up the optical mouse again, and it didn't return from hibernation with mouse movement. I thought I'd just get a new optical mouse and forget about the experience. After declaring my problem solved, tonight out of curiosity I hit a key on the PS/2 keyboard, and lo and behold, it returned from hibernation again. I now remember the computer starting up from hibernation the day after I got it, and I'm sure I probably elbowed the keyboard. It's definitely in hibernation and not standby, I've compared the two states and standby is much quicker.

I have an older dual core Windows 7 pc that I have been using as a file server. It worked fine until recently, when it started having little "freeze attacks". In Windows Explorer, when I would click on a file or folder, it would freeze up for a few seconds, then free up. If I then clicked on the folder again, it would highlight. When I would click on a different folder, it would freeze up again for a few seconds, then free up and allow me to click the folder. When frozen, the mouse pointer would still move around, but clicking on anything had no response. I should also point out that when I re-booted it, it would freeze at the Windows logo (all motion would stop) for several minutes, then would continue booting into Windows.

I wasn't sure if this was Windows 7, hard drive, or other hardware issue, but I have a faster pc to take over the file server role, so thought I would re-build it and see if that solved the problem. I formatted a different hard drive, and installed Windows 7 on it from scratch. However, at the end of the install, when it re-booted to start into windows, it froze at the windows logo (logo stopped moving). I waited for 2 or 3 minutes, but nothing happened. I left it for a while and came back to discover that it was at the screen prompting for new user name, etc. I tried to continue, but when I type about 2 characters, it will freeze for 15 or 20 seconds. Then I can type two more characters, and it will freeze again. I can't even get the thing ful... Read more

I've been having this issue since the last Windows 10 update, When I first power on the computer the mouse and keyboard are slow to respond as if there is lag between them and the computer. Also the HDD activity light is going nuts. When I restart the computer everything goes back to normal. I've disabled all 3rd party start up services and programs, and this did not seem to help. Any thoughts? I'm at the point where I am ready to do a fresh install of Windows 7 as I have that CD and the Windows 10 was the free upgrade.

Hi.So as the title states, I'm having a problem with mouse/keyboard input.  Occasionally (usually if I'm doing something that puts the CPU under load, not necessarily full load, but under load.), my keyboard and mouse will get this delay where if I press a key or press a mouse button, the computer doesn't seem to register it until a second or two later.  It will normally happen now and again in short bursts, not really something that happens consistently and continuously for a long and extended period of time.(Okay, so I'm gonna put the problem into a small list, since it's a little easier for me this way)>Pressing a button on the keyboard or mouse, the computer will not do anything with the input until a second or two later.  Example: Pressing forward, backward, then side-strafe in a game will cause it to not register for a second or two, then I'll move forward, backward, then sideways after that 1-2 seconds.  Typing in something like Trillian will cause it to register the first few keystrokes slowly, and then suddenly type everything out in a quick burst.>Sometimes, if I press a button quickly and not for an extended period of time, the computer will act as if I held it down for several seconds once it registers.>If I press enough buttons while the delay is still going or if the keystrokes are starting to register, the computer beeps. I've got filter keys, sticky keys, and bounce keys turned off completely with no way to activate them excep...

If they both use a unifying receiver you can link them both to just the one receiver. It sounds like you might have linked a device to two receiver's? I didn't think that was possible? Unplug one unifying receiver and see what happens. The unifying software will let you link and unlink devices. My keyboard came with a mouse I will never use. I just linked the keyboard to the unifying recover for my trackball. Then gave the mouse and its receiver to my father.

I have an Acer Aspire M computer with a touch screen that runs Windows 8.1. I was having issues with the touch screen, so I went to download the drivers from the Acer website. However, when I restarted my computer to complete the installation, it wouldn't allow me to use either the mouse, touch screen, or keyboard.
Normally, after loading, a personalized picture will appear on the screen, displaying the time, connectibility, and strength of the network. The user is then supposed to swipe up, click on, or press space to move the picture, at which point the login screen appears. My computer loads normally when starting, but won't allow me to use the mouse, touch screen, or keyboard to move the picture out of the way, so I cannot access the login screen.
I have already contacted the Acer company support and attempted to use the battery reset pinhole, but to no avail. Is there anything I can do, besides a factory reset or using it as a cat bed?

A:No touch, mouse, or keyboard input after computer reset

using it as a cat bed

Probably best.

You could uninstall those drivers, looks like you will need to do it from outside windows.

You would need a decent winpe., which you probably don't have, nigh on impossible to make one given your situation.

System restore to just before the problem may do the job.

Try that and see.

Hey gang,

Well to start of I'll describe the problem. My mouse sensitivity alternates a notch from normal to fast or normal to slow and back again whenever I am logged on to the computer i.e while browing, gaming or whatever. Also while typing and having typed correctly, mind you, something different is entered in the field i.e while chatting online or writing an email.

The steps I've taking to pin point the problem include buying several new mice and doing clean installs of windows and applications. I've also tried updating drivers etc. The problem persists.

Some background information. I've been playing world of warcraft for a couple of years now. Prior to this, I kid you not, I hadn't even heard of keyloggers. Malware, trojans and virus sure but not keyloggers and rootkits. My gaming account got "hacked" 2-3 years ago and that's when the bleep hit the fan so to speak. After that most of my email adresses got compromised and I started to have malware problems.

It has come to the point where I actually suspect the gaming company for introducing malware. Abit extreme but that's what malware does to you. So instead of going bonkers I've decided to, FINALLY, try and fix the problem. I hope you guys can help. Here are the files. Also to note: my computer has very few programs installed ast the point of the scan because I did a clean install of windows 2 days ago. The programs include avira, world of warcraft and google chrome. Anoth... Read more

I flipped the receiver to radio and it's fine. Typing on my backup computer now. The sound from this computer to a different input on the same receiver is fine.

The mouse and keyboard are fine here too. But none of my mice or keyboards work on my main computer. I have a wired mouse and keyboard bridging the two computers with a KVM so they can share the same screen too. On the main computer I also have a couple of mice and a keyboard attached wirelessly. This setup has been fine for a long time. Years.

But with the mouse and keyboard unresponsive (I've unplugged all but the wired one), there's no way to shut it down safely.

Can someone provide a plan to diagnose the problem or tell me how you solved a similar problem please?

A:Buzzing on audio output and loss of mouse/keyboard:can't shut down

First up is the machine listed in system specs the problem machine? Also have you tried other mice or keyboards wired or not on the problem machine.
Even if you can get at least a keyboard to work you can safely shut down using that.

Now the set up I do have a problem imagining it in my minds eye it sounds quite complicated. having said that if it has gone for years like that then maybe you have some serious hardware problems with either the plug in devices, the machine components or both.

Now I have Googled KVM (never head of that abbreviation and never used one) and find it is a piece of equipment too that could be going south?

Can anyone help me out here? I'm looking for a simple app I can run from my system tray, that when a certain hotkey is pressed, blocks all keyboard and mouse input, only unlocking it with a certain password (or hotkey press). It'd be a lifesaver and I'd love a suggestion.

I have a three year old inspron desktop running updated windows 8  Suddenly NONE of the input devices are working.  I've tried several different wireless mice, and I've tried both a wired and wireless keyboard.  NOTHING.  I've tried unhooking all, rebooting, then hooking them back up... still nothing.  Tried rebooting with them installed.  Tried switching USB ports.  ARRRGGGHHH.  Since I have no keyboard I can't do safe start (don't even know if that works with windows8 ).
I do have a "repair disk" that I created when the compter was new.... tried rebooting with it in the drive.... didn't do anything other than restart the computer with the same non-functioning input devices.  
I hear my external harddrive working... so it must be doing something... so I guess its not all USB devices that are down.
I did install new logitech software last week, but it worked fine for several days, just quit working when it woke from sleep.  I'd love to uninstall it, or do a system restore, but I can't do that since the mouse is not working.  
Any suggestions/help would be greatly appreciated.

I have a windows 7 computer here is the system info.
I7 quadcore. MS-7582, I think
Standard hdd and a backup.
1000 watt ps.
MSi 660 Nividia graphics cards.

I have two of these they are almost identical.
For no apparent reason the one I'm having trouble with just started shutting down the PNP that were plugged in.

I could hear the "disconnect" sound. First I thought I had overloaded the PS, but that doesn't seem to be the case, all of the power ports seem functional.

I can get the computer to start, and go the windows start screen but with on input device I can't do anything.

Can't safe boot, can't boot into bios, I've tried the install disks and it won't boot from there and a recovery disk didn't work either.

Cleared the CMOS, pulled the battery.

Nothing helps.

Installed a 3.0 USB card which will give me power to my phone charger but nothing else.

Tried an old PS keyboard with a USB adapter that didn't work.
Bought an old keyboard with the PS plug. That didn't work.

Pretty wierd

I know this is a PIA for anyone trying to help. So I'm going to thank anyone in advance that takes the time to help.

I can get a new hard drive it that might help.

I can LAN together the two computers if that might help.

I can make whatever kind of start disk from the other computer. I have all the disks and keys.

I purchased a A485 and worked well but quickly replaced Mech harddrive with SSD. After reinstalling windows 10 I noticed I loss the function of the backlit keyboard, as well as my mouse cursor kept freeze when using the Track point when I would use the middle button for scrolling. all drivers up-to-date and even tried reinstalling windows and drivers again...still have this issue the mouse freezing is the must fustrating since I primarily use the Trackpoint to control my mouse functions. I found that locking (windows + L) and login back in frees up the mouse again...but typically freezes shortly after pretty fustrating, especially when one of the main reasons I buy Lenovo is their trackpoint. I've seen people have similar issues but no resolutions in their threads.

I have a fairly serious issue on my hands.
2 days ago, my computer decided to stop taking input from anything (mouse, keyboard, and touch). I am unable to do anything past the Windows splash screen. Going into the BIOS shows that the computer is working normally, and my mouse, keyboard and touch screen work there without issues. I really hope I can get this thing working again, as I haven't backed up files to a cloud. Please help ASAP as I need my PC running!

I have a Dell D610 laptop w/ XP Pro SP2... or had.

I have a corrupted registry entry hosing the keyboard input. The mouse works fine up until the point when I kit the first key on the keyboard when under the Graphical Windows interface. After I hit any key, the mouse freezes as well. This happens if I use the laptop keyboard or an external keyboard connected to a PS2 jack.

I have performed hours of troubleshooting and it is not the keyboard hardware. Keyboard input works during all non-graphical UI (BIOS, Recovery Console, etc.). I even removed the drive and plugged it in to another computer. I made a copy of the WINNT\system32\config files (sam, default, security, system, software) and replaced them w/ a copy of these files from WINNT\repair. The computer boots to Graphical Windows and I am able to type in this session just fine.

How can I "erase" the keyboard driver corruption in the registry (or perhaps a corrupted driver file or set of files)? The problem is that I can't boot the system to a point where I can edit the "corrupted" keyboard entries. I can't use the Recovery Console because I don't have the Administrator password. So I tried to install SP3 from a bootable CD. The minute it asks me to type in the Product Key (a graphical dialog box), input is frozen a the first keystroke (even a key like Caps Lock). Can I actually edit the registry that resides on the boot drive while it is connected to another computer? Any other suggest... Read more

Well my Asus P6T motherboard has AGAIN stopped giving me a video signal. i wanted a last opinion before i send it back to Asus. Basically i restarted my computer and when i turned it on i didn't have video signal. after playing around with the internals and such i can get it to work but then after about 30 secs it loses signal again. (i almost got into windows when it worked) so it's POSTing. there doesn't appear to be any loss of power (my fans keep running at the same speed and all the LEDs are on) the vid card is brand new but i was playing on it earlier and at the same settings as my old one so i strongly doubt it's that. it appears the Mobo is losing connection to the PCI bus. i'm truly stumped here and any input would be appreciated.

I doubt i'm lacking resources in my pc:

950W psu
Intel i7 920 cpu
NVidia GTS 250 1GB
Asus P6T mobo
1TB sata drive

thanks in advance everyone.

PS: i've swapped in my old gfx card, reset the cmos, disconnected everything but the essentials to run it, moved the DIMMs around, everything. the first time i got this board it was DOA and i got it replaced (which worked). most problems of this nature say the board isn't going through POST but mine seems to be.

Hello. I recently upgraded from an old IDE drive to a SATA drive and installed everything fresh including my OS. After I got everything set up and personalized the way I had it I began installing games. The first I tried was Battlefield BC2. Ingame on a full 32 man server I was getting 50+FPS constantly with maxed settings in DX10. I played for a while and figured I had everything worked out with the new SATA so I started mass installing all of my games. After everything was finished, I rebooted, loaded updates, etc and the next day when I went to get on BC2, my framerates were in the toilet. 25-30FPS instead of the 50+ I was accustomed to. I checked the drive and it was 85% fragged for some reason. I defragged and tried again but got no performance increase. It was then I noticed that when the game is running my CPU usage is at 100% the entire time. I did a bit of overclocking (each core over by 200mhz) and noticed a bit of an increase in performance. I have stock cooling however and don't want to keep my CPU overclocked at 100% load with it. My question is, why when I had fresh installed everything and before I loaded all my other games onto the drive was BC2 working perfectly and smooth, but after I installed my other games the performance took a crap? Thanks in advance for any help offered.

I plugged in a new fan to help keep my hdd's cool, and i plugged it into the board (turned off), and when i turned it back on, everything was good, speed fan detected it and it was running smooth. But, i noticed that my hdd light was continually on, but the hdd's weren't reading, so i shut down, and i unplugged the fan, hoping maybe that caused it. When it restarted, suddenly it was in 640x480. So, i checked the display settings, now it suddenly had every resolution up to like 3400x2048, but not my resolution of 1680x1050.

Frustrated, i uninstalled the video card, and reinstalled, same thing. Sooo, i uninstalled the drivers and software, restarted, and reinstalled. SAME THING.
Frustrated, i slammed my fist on the keyboard, and then came here.

I have a Maxtor Fireball 40GB HDD connected via USB to my computer. It was working fine until a couple of days ago and I cannot now access it. I get a message stating that the drive isn't formatted. I've looked at the Disk Management utility within XP and the drive is shown (Only the drive letter), layout = Partition, Type=Basic, File System is blank and it shows as having 100% free space. The drive had a FAT32 File system and I suspect this has been corrupted some how. Is there a way of repairing the FAT without losing the data on the drive, or do I have to re-format?

I've recently upgraded my GPU and PSU to a GTX 650TI 2GB Boost Superclocked and Seasonic M12II 620W, and noticed a sudden loss in RAM after installing the new hardware. Originally, my PC had 6.00GB of RAM, but when I check the system information, it says that only 4.00GB of RAM are present. Is it possible that the introduction of these components affected my RAM? I'm completely in the dark with this one, any help would be appreciated.

For a couple of years, I have been using Philips GoGear Vibe MP3 plaers through a Belkin 7 port hub with no problem. A couple of days ago. the player was no longer recognized by the computer, eithe through the hub or connected directly to the computer ( Dell Dimension 8400 4GB memory).

The wireless mouse, which was connected via the hub, froze, and operated once I connected directly to the computer. Hard drives connected to the hub worked, but flash drives no longer did.

I changed hubs, changed cables, re-installed chipsets, etc., etc., but everytime I connected the Philips player, it, in fact, destroyed the hub's ability to handle all connections.I also tried a new Philips with updated firmware, and that did not work.

Philips' tech support has no idea what is wrong. Since I just installed another Belkins 7 port hub ( I also had the same problem with others manufacturers' products), everything works as it should, except that I stay away from connecting the MP3 player to the computer, either through the hub, a cable to the hub, or directly to the computer. To download data, I save to a flash drive, then use my notebook (W7 OS) as a transfer conduit from flash drive to MP3.

So, if anyone has an idea of what could be , or is, the problem, I'd appreciate hearing from you. Thanks.

A:A sudden recognition loss by XP SP3

Does the Hub have a power adapter? Is it the correct one? Be sure to use the power adapter on the hub. Be sure you are plugging the hubs power adapter directly into the wall and not through a Surge Protector or extension cord. Are you plugging the source USB cable (from the Hub) into the Back USB port of the computer and not the front? The back USB ports are stronger. Devices that are not being recognized or crashing while using a hub are caused by not enough power. Try the above and also try a different USB data cable from hub to the computer. Try a different port on the computer. Low powered USB devices like keyboards and mice can go in the front because they don't require as much power.
If all of that fails, then With the hub installed, go to Start/Run and type devmgmt.msc and press enter. In the Device Manager, do you see any devices with yellow marks? or under USB, do you see an Unknown Device? if so, right click it and uninstall it. Unplug the Hub and restart the computer then after it loads, plug the USB source cable back into a different USB port on the computer.
What is the make and model of your computer? If it is a name brand computer (HP, Dell etc) Go to the manufacturers support/download drivers site type in your make and model and download the Chipset driver for your model.

Hey there guys.

Basically all of a sudden my computer has started to dramatically slow down randomly.

It seems to be happening when I do something a little heavy like rendering, but generally doesn't go away and I'm forced to turn off my computer. If I try to ctrl-alt-delete to check mem usage I get an error saying it couldn't open. I have used this pc for a long time and it has always worked fine. I re-installed windows hoping this would help but it hasn't, leaving me to think its some kind of hardware error.

Hi. Just found this forum while looking for some assistance for a problem that has literally occured overnight. I inherited this computer from my son after he moved on to a new one.I am not exactly a computer noob but certainly no expert either. I have been using the computer for about 6 months with no problems. I was using it late Saturday night and there was nothing wrong with the sound. I turn it on and fire it up Sunday morning to see the speaker icon on the Taskbar has a little red cross along side it and a box telling me 'No Audio Output Device is Installed.' I found this forum and started looking through it trying everything recommended.I tried System Restore but that made no difference. I tried the Windows Help with the option to automatically fix the problem but it didn't. If I go into Control Panel...Hardware and Sound...Sound...Manage Audio Devices, I get a box with Digital Display Audio,AMD Audio Device,not plugged in.If I right click on this I find 'Show Disabled Devices' and 'Show Disconnected Devices' both ticked. I'm pretty sure I used to see a Realtek icon on the Taskbar but there is'nt one there now although I do have a Realtek folder in my Programs but there is no exe file in there? Anyway I would be grateful for any advice or suggestions you could give me.
Regards and thanks in advance.

I'm putting together a computer for my dad out of a few parts I no longer need and was creating a new partition on the hard drive in preparation for a format and installation of Windows.

However, whilst the the partition was being created the power died. Now the machine won't switch on. There is a red LED on the motherboard that lights up when the power button is pressed and the processor fan twitches, but doesn't start turning. There's no power to the CD-ROM drive.

I've tried disconnecting all disk drives, removing/switching position of RAM etc, but nothing seems to work.

The case and power supply are new and the machine was working fine for 30/45 minutes prior to this happening.

I'd appreciate any thoughts - I'm afraid it might be a problem with the motherboard, but am not really sure.

Thanks in advance, Jake
