Windows 8 - All USB Drivers Suddenly Disconnected Even After Restart
Feb 6, 2014
I am having trouble with my USB connections. They will all be working fine if the computer is idle, then when I start doing things all of the drivers get disconnected, and won't reconnect after unplugging and replugging them in. Restarts don't work.
my problem with my laptop is Windows 8 BlueScreen and also Restart my laptop Without display BlueScreen and sometime this happened for more than 1 time regularly. this problem is happend Sometimes more than twice a day, when i'm doing regular things like reading a .pdf or watching a movie or gaming.
note1: Here is the .zip file created after i've ran SF Diagnostic Tool Scott2020.rar
note2: 1month ago, Updated Windows 8, and components drivers (video, audio, ethernet).
note3: Last night, I installed last updates for Windows 8 Completely.
I have a Sony Vaio running Windows 8.1 Pro. I was on cs portable with a USB mouse and I pressed a few keys and the mouse stopped to work. It came up with the message that it was not recognized. I tried to uninstall the USB drivers, but had no luck. This problem has been going on for a few days. I tried other solutions but they didn't seem to work. The red LED light was on.
I don't know why but my external hard drive isn't showing up when connected.. Windows makes the connection noise when I plug it in but it don't show up in disk management, device manager or anywhere else... If I plug it into a regular usb port it works fine... And its a usb 3.0 capable drive it worked before....?" I tried the new hardware wizard in device manager and didn't see anything... drivers all look fine....
So I was using my computer the other day and suddenly my clickpad started tracking very poorly. Before it used to be accurate when it was tracking my finger, however now it jumps around the screen when I move my finger around on it and it takes a full second before the clickpad translates initial input to the mouse. If I put my finger on the trackpad and start moving it the mouse will jump to the location where the pointer should be and will not show the track that the pointer took. I uninstalled the driver and reinstalled it and I am having the same problem. I have restarted the system multiple times and it has still not resolved the issue. I cannot click on anything due to the insane inaccuracy of the trackpad.
I have a Windows 8.1 Lenovo notebook and a Toshiba Satellite Windows 7 laptop, and a mouse.
Well, the mouse has been working fine for 4 months, but suddenly, the mouse has stopped working in my Toshiba laptop. As I didn't know how to fix it, and as Toshiba laptop was full of crap, I've just formatted its HDD and made a clean install of Windows 8.1 and updated everything.
After that, I've plugged the mouse in and the same error: it connects and disconnects all the time. Sometimes, if I'm in the Device Manager refreshing the devices, mysteriously it start to work, but just for a few minutes. Sometimes, and just sometimes, the Device Manager shows that there's an unknown device connected to a USB port that is not working. The error code is 43.
That mouse works perfectly in my other notebook, the lenovo. I've connected a different mouse to the Toshiba and it works perfectly, in any port. So that makes me say this:
-The mouse is not broken, cause it works in my other laptop
-Toshiba's USB ports work nice cause any other device I connect works seamlessly
-After a clean install, it can't be a software problem
New Machine turn on after being disconnected from the power plug back in a few minutes later , turn on , BSOD ,, restarts then starts fine and runs no issues , shut down fine restart fine , take away from a power source wait a few mins plug back in turn on BSOD lol
We were sent some Surface Pro 2 Tablets at work. They were already setup with the programs we needed, however they were not behaving correctly. Kept getting network errors for the domain, as everything else on the network was working but that.
Apparently at least unjoins our domain, restarts, and now I cannot login for anything in this world. I cannot get any other user accounts to show up but the last person who logged in, who was an administrator on tablet under our domain, and the password simply does not work. I have tried restarting in safe mode with and without network and that doesn't work because it won't recognize the password for the user. So I thought system restore would work but apparently I need to login to the account to do that as well.
Also tried rebooting to the command prompt. I apparently need to login for that as well. I have tried rebooting into a password recovery/reset disc but I cannot get it to boot to the cd, or at least if it is, it's certainly not reading the disc (which I knows works for XP & 7). I cannot do a reset password usb because alas, I need to be able to login to be able to create one of those. I've looked at several online things but most of them start with "you need to be logged in".
Recently I bought a new lap top and installed Windows 8.1
I have an issue with the Mouse/s. I tried 2 different mouses and I encountered the same problem with both of them, so I know it's not a mouse problem. Note that both of these mouses work perfectly on my other/older/Windows 7 and previously Windows XP lap top, so it's not a mouse issue. It's either a driver problem or something else.
I have tried all 3 USB ports I got and it does the same thing.
When I turn on the lap top, if the mouse is plugged or unplugged and I plug it afterwards, it doesn't work. If however I turn on the lap top, plug in the mouse, and the restart the lap top, when it restarts the mouse works fine all up until the lap top is turned off again. And then to get it to work again I have to turn on the lap top, with the mouse plugged, or plug the mouse after it's turned on, then restart the lap top, and then the mouse works fine.
Apparently, this is not very convenient. It's a major inconvenience.
p.s I never had this issue before on any other PC computer or lap top, whether it was Windows XP or Windows 7. So it's either a Windows 8.1 issue or the new lap top issue, or a driver issue.
I have a clean Windows 8 install with latest updates. I plugged the computer into LAN via standard ethernet cable and everything looked alright, however, it seems that there is some problem with downloading files (be it through browser or a different service, such as win update). Usually the download starts normally, downloading about 5-7 megabytes, but then the download freezes, as if the internet connection had disconnected. Thing is, it hadn't, I can still browse websites and ping hosts. The downloading sometimes randomly resumes for another 700 kilobytes to 2 megabytes, though generally not more. Other computers not running windows 8 in the LAN do not have this issue, which leads me to believe it's not connected to router nor ISP.
Sometimes, it also fails to load a webpage, hanging untill a manual refresh is performed or untill I replug the ethernet cable.
- Update ethernet drivers
- Try different speed & duplex - Update windows to the latest - Disable windows firewall and smartscreen
My laptop has been giving me an issue for several weeks where it will not connect to the internet. When I attempt to do ipconfig commands it tells me "No operation can be performed on Local Area Connection 13 while it has its media disconnected." As well as Local Area Connection 12, Bluetooth Network Connection, Ethernet, and Wi-Fi.
I'm having an issue where if my USB devices are plugged in when i start my computer they are fine. but if i try to plug in a thumbdrive after it's already been turned on it won't recognize it. nothing.
Just Ran the SFC /scannow and i don't know what to make of it. it is attach The Attached file has the SFC details. not sure what to make of it.
Running Windows 8.1 x64 Gygabyte: z68a-d3h-b3 (will attach more if needed.)
I have an Asus PC running W864, I have a Seagate 2 TB Harddrive and I have two 2TB Hard drive connected by USB.
Sometimes when I leave my PC running while doing other things I come back to it after a few hours and the PC is showing a black screen the message "BOOTMGR is missing. Press Ctrl Alt Del to restart" This happens about once or twice a month, I can see no pattern or event that triggers it.
When I press Ctrl Alt Del the PC restarts and comes back to the same message.
If I reboot to a bootable repair disk or Windows 8 install disk my OS and Hard drive are not found, but my USB connected drives are.
I have to turn of my PC completely, I take out the plug, and switch it back on, sometimes it reboots properly to the Start screen but sometimes it just goes back to the black screen with the BOOTMGR is missing. Press Ctrl Alt Del to restart message.
What seems to work always is if I turn off the 2 USB attached drives turn off the PC then restart, that works 100% of the time as far as I can recall.
I suspect my had drive is faulty but I have taken the PC to the supplier and their tests show all is okay, even when I run Seatools for Windows it checks out 100%.
Seatools for DOS does not find the Harddrive, I believe this is a W7/8 issue.
I have repaired the BOOTMGR using the process shown here, How to fix bootmgr is missing in Windows 8 But since Windows 8 disk found the Harddrive I suspect the PC would have booted okay anyway.
Active SMART says it is okay and Event Viewer in Windows 8 does not show any related errors.
So I had to reinstall Windows 8 on my PC, and as usual i install Drivers and such first. Normally it worked, now after i restart the Computer to finish the Driver Updates, i get Black Screen after Windows 8 loading Screen.
My wifi only works correctly at home. When at home, I have no problem and a good, solid internet connection. When I am anywhere else (friend's house, school, work, even my phone personal hotspot), I can connect to the internet with no problem, and it even shows as "internet" on the wifi screen so I know it is getting it. However, when I attempt to load a webpage it shows as if there is no internet. I have tried Chrome, Firefox, and Internet Explorer. I have done the ipconfig renew and release, when I do release it says "media disconnected". I have also tried forgetting the network and reconnecting.
Unfortunately I don't have access to the internet in these locations to troubleshoot.
I have a problem with my microphone Sound Blaster recon3Di : it is shown as "disconnected" (both by windows and the sound blaster control panel) and does not work (it has never worked since I have the laptop)... I have tried to upload the drivers but it did not change anything...
I own an hp pavilion sleekbook 15. Just out of the blue my mouse and touch pad stopped working after a restart. I download a new driver from the hp website, synaptic touch ps/2, installed it and still nothing. After several tries I don't know what to do anymore. I checked the device manager and nothing is installed, when I check the control panel it says reinstall.
I have a Lenovo y50 and it used to boot in 12 seconds, but recently started to take over 30 seconds to boot. I've had this laptop for around a week now. It happened ever since I reinstalled my nvidia driver. Im not sure if its just a coincidence that it happened at the time I reinstalled it. I made sure all traces of the driver were gone before reinstalling it. The loading circle in the beginning of the boot used to move smoothly but now it visibly lags and moves slowly. I've tried the "Clean up my PC" option and it still has the problem. Here is the event log:Link
I disabled fast boot and shut off the computer and then turned it on again(not restart). Then I enabled fast boot and now it boots at the time it did before. Very strange lol. Now it boots even faster, in around 10 seconds as opposed to 12.
I upgraded my Windows from 7 to 8 pro using the 40$ offer and it worked like a charm Unfortunately, today my room-mate tried to install a cracked version of Microsofot Office 365 and he ruined my computer. My windows 8 become inactive and the Windows keeps asking me to activate it. I saw a lot of soltion for the error code 0xC004F074 here and all of them require the product key which I do not have.
Cant get any sound via built in speaker or headphone jack. Have checked settings through speaker volume icon lower task bar, Dell Audio control icon, and checked for audio enabled or not through device manager/soundvideogamecontrollers/Realtek high def sound etc. All looks perfect.
This loss of sound MAY have happened after running SUPERAntiSpyware that my ex-computer "expert" installed and instructed me to run regularly. I lost sound also when he last serviced my computer and installed SUPERantispyware (among other unknown things he did), but he somehow restored the sound through changing a power management option I think. I just tried that again to no luck.
But what it means when someone says "install new drivers" or "reinstall drivers" - my Windows 8 came preloaded and upgrade to 8.1 has failed twice so I gave up - nothing to do with this problem arising though.
I have suddenly got this problem. To the best of my knowledge I haven't installed anything prior to this happening. My pc used to take prob less than a minute to boot, but now takes around 10mins. Once booted it runs fine.
I have updated and scanned with Sophos AV and Windows defender and both show clean. I cannot boot to safe mode as the start up is so slow that nothing happens anymore hitting f8.
I have defragged and optimised both HDDs and run chkdisk.
No warnings in device manager. A few errors in eventlog but nothing major or consistent - I can get them if wanted. I used SFC /SCANNOW Command which initially failed so I used Dism /Online /Cleanup-Image /RestoreHealth this appeared to work and then on running sfc /scannow then completed successfully with no errors, but no change in boot speed.
I then used system restore to restore the computer to prior to this happening - this completed successfully, but still no change on the boot up speed.
I then downloaded and ran the Windows Assessment console and have the logs, but am unsure really where to go with them. They are attached (Axelog).
My laptop is never usually that slow but last night it was really slow and I restarted it but it took about 5-10 mins to get to the gateway loading logo an after awhile it said diagnosing but it didn't do anything, this morning I switched it on and it came on the login screen straight away but it took me like 5 mins to login cause it was being so slow but I finally log in and it takes like 10-20 seconds just to right click on something so I went on task manager to check if anything was full and disk was 99% full by things like system, AVG, service host, host process but I've never has a problem with avg.
I have a dual boot Win 7, Win 8 setup. Suddenly the audio has stopped working on Win 8. (Works fine on Win 7) I checked for driver updates, even "installed" an old driver which didn't actually install. The volume control shows its trying to work, puff of green comes and goes at the bottom of the slider.
However I've tried "cleaning" for other concerns and that made a real mess of the setups for several programs. I suppose I could do a refresh but that's equivalent to a re-install..
I have had Windows 8 for approx 1 year and just upgraded to Windows 8.1 last week.
I installed bitdefender total security at the same time and everything was fine for a few days until one morning I woke up my Laptop to find I couldnt open a software program. Further investigation has found that I can not alter anything on my machine.
I have only the one user account which has my name, email, Administrator and password protected showing.
I can use my laptop still but have no admin rights at all.
When i try to open command prompt (admin) it takes a few minutes to come back with an error saying cannot access specified path, file folder etc...
I cant even restore my system back to factory settings. How can I restore my factory settings from this point??
HP Pavilion with Intel Core i3 running on Windows 8 and NVIDIA GEFORE GT 630M 1GB
My relatively new (about 2 months old) laptop running on Windows 8 suddenly became slow. I noticed it starting yesterday when it became really laggy. Just a few days ago it was working just fine.
I tried to look for solutions online and was worried that it might be caused by malware. I did a quick scan with Malwarebytes and it found no infections.When I boot in safe mode, it seems pretty fine. I tried doing a system restore but I was also informed that it wasn't completely done probably because of an antivirus.
My antivirus is Norton Internet Security and I've read that Norton can be such a hog so I've tried disabling it though not entirely and it hasn't been uninstalled yet. I've also tried running a chkdsk /r because going to Tools > Check for Errors on my C: drive said that there were errors that needed repair.
It has become less laggy but apparently not totally (not to previous state). My task manager however still shows 100% disk usage. Previously Norton would be listed among the top but now it's usually "System" and I don't quite understand why.
