USB Ports Have Suddenly Stopped Working?
Mar 31, 2011I have a Compaq Presario CQ62-215DX, running Norton Internet Security and firewall through Windows 7. I sucessfully installed new Wireless LAN and Lightscribe system software several days ago, along with the Live Essentials, Realtek and Windows 7 Updates. Everything was operating correctly yesterday, but when I booted up my computer today my wireless mouse refused to work. After trying a fix involving a USB stick, I realized that none of my USB ports work. The ports light up when I restart, until Windows 7 finishes logging in, and once it begins the drivers refuse to work. Is it because of the recent updates? Because I cleaned up my back-up copies?

Aug 12, 2011I have an older Dell Inspiron 5100 that's been rock solid since day one. I recently transferred all my music from my PC to my Seagate FreeAgent GoFlex so I could organize my files while I was out of town on business. When I got to my hotel and plugged the Seagate into the USB port the laptop would not recognize it. There's two USB ports, one of the USB ports does nothing at all when I plug the drive in (not even a 'Ding-Dong' sound). The other port at least responds but still not recognized. By "responds" I mean Windows responds with a "Dunn..." sound; not the happy two tone sound of a device actually being recognized and available, just a "Dunn..."I've used this drive before on this laptop on several occasions so I know it's compatible. I also came home and plugged to drive back into the PC to see if the drive itself responds. It does, and all files are there and happy. Also, when plugged into the non-responsive USB slot the light on the drive blinks a couple times, the platters spool up for 15 or so seconds then goes out. When plugged into the other USB slot (the one that goes "Dunn...") the light comes on and stays on and the platters spin untill I unplug the device. But it's still not recognized.

Jun 30, 2012Yesterday when I turned on my laptop windows wouldn't start and launched its error recovery. When I launched the startup recovery it gave me a black screen for 5 minutes, then an Acer desktop screen with nothing on it. The loading light will stay lit up for 5 minutes and turn off without the computer doing anything at all and stay at that screen for hours on end.

Jan 7, 2013MY daughter was having problems with it simply turning off. After looking at and running Real Temp and Prime 95, I believed it was simple over heating .It is under warranty so I took it in for repair, I just picked it up and they said the fan and vents needed cleaning, that is why it is getting hot and shutting down.Now I re-ran Prime 95 and it still shut down after 1 hour roughly. Real Temp said it was 89 Degrees C.
So is this normal for laptops??? I costume build my PC and it never shuts down on running Prime 95. Even I did overclocked it.

Feb 8, 2012Both USB ports at my laptop (Toshiba Satellite C650, Windows 7 home premium, SP1, x64) stopped working after plugging in and unplugging several Garmin Forerunner 305 watches in a row. Everything looks all right in the device manage (no exclamations marks). I have reinstalled everything that has something to do with USB in the device manager, several times. Updated BIOS and used Windows update to get all the latest drivers and fixes.I have taken out the battery and let the computer "rest" for several hours without any power supply.I have tried to do some changes in registry key according to these instructions: USB ports suddenly stopped working in Windows 7 RC1 - Microsoft Answers (I managed to delete Lowerfilters).And of course I have tried with different USB-sticks, mouses, external hard drive etc. There is no power in the ports. When I plug in my Garmin Watch it does not charge.I installed and tried two registry cleaners (TweakNow RegCleaner 2011 and Glary utilities). After using them I got some hope back when I got a bit of reaction from one of the ports. A few times after plugging in something it started to install the driver but stopped immediately - telling me that the driver cannot be installed because the device is not plugged in (while it is).
I consider to do system restore to factory settings but before that I have to copy and save everything which is a bit complicated since non of the ports is working. If the restore to factory settings does not work, then I believe there is a problem with the hardware and I have to get the motherboard replaced.
USB Ports Stopped Working?
Dec 28, 2011I am in a spot of bother since I have to give an important presentation and all of a sudden my USB ports (3) in HP pavillion dv6(running windows 7 64 bit) stopped working. I plugged my friend's ipod touch to charge from the computer and it did not work and after that none of the ports will work. I tried reinstalling the drivers,restarted the computer multiple times and even ran a virus scan but its of no use.Out of the 3 ports only one says "windows detected a problem with the device", the other 2 wont even say anything. I even checked at the registry keys to see if the USB ports are enabled and they were fine. My warranty expired this December so now I have to pay HP for any trouble shooting

Sep 8, 2011Yo people. So it was a regular day, found a program online and created a restore point before installing... suddenly about two hours later while surfing the interweb boom!! Internet Explorer stop responding so I think "it's not so bad... it happans timw to time" but the only differents is that the message doesn't pop up, like windows doesn't even relize it! But continuing on, I right click on the taskbar to start task manager because clicking the exit button fails the taskbar AKA explorer.exe caught the same flu as IE. So now I can touch the taskbar so Ctrl+Alt+Del is left... screen turns black as always when I do the keystoke but it stays black. So I shut off my computer. Start-up was a little more slow and worked fine before I open IE and it starts all over again. I try restoring, scanning (later with various other antivirus) nothing found, memory test (normal), and everything else like uninstalling unused programs and fixing the registry with Registry Repair. I got Startup Delayer which helped with the slow Start-up but nothing eles. But sometimes like 1/5 times my computer boots up and i perfect like before but when I turn it off it happens again on the next start-up

Apr 27, 2012My USB ports on my ASUS c90s laptop suddenly stopped working one by one. After reading around the internet it seems this is a windows 7 problem. When I go to device management I have other devices not working. Two Base system devices under a PCI bus category and an "Unknown Device". The unknown device is under the Intel(R) 82801GB/GR (ICH7 Family) LPC Interface Controller - 27B8 section. It has no driver, even though I downloaded the driver manually it still doesn't work. I've tried removing my battery and then replacing it. I disabled all the USB ports then restarted. I've even uninstalled them aswell as the unknown device.I went to theregistry:HKEY_LOCAL_MACHINESYSTEMCurrentControlSetControlClass{36FC9E60-C465-11CF-8056-444553540000}and found one solution to delete the upper and lower values. I had no lower values just a "lowerlogoversion" but I did delete the upper value. I then restarted and attempted to plug my mouse into my USB again and it was recognized for about a second and the red light under my mouse lit up but then went away.

Dec 12, 2012My laptop has suddenly slowed down considerably. I've run eset online scanner and scanned with my antivirus Trend Micro Titanium and found nothing at all. I've tried running Ccleaner and using the registry cleaner. I've also tried defragmenting my hdd but nothing is working. Overall its is generally slow but alot of the time Windows explorer freezes and stops responding and needs restarting.I have an asus K55VD notebook with Windows 7 Home Premium SP 1, quad core i7 processor, 8gb ram, 2gb dedicated graphics and over 200gb of free space on my hdd. If it makes any difference I have windows 8 installed on a separate partition although problems didn't start when I installed it.

View 8 Replies View RelatedUSB Ports Stopped Working After An Internal Power Jack Is Replaced?
Feb 14, 2012Basically, my HP DV6-3065EA running Windows 7 Home Premium (x64) laptop died. I went into a computer shop and asked how much a simple diagnostic test would be to find out how much a repair would be. He quoted me 90. Phew, jog on! That wasn't going to happen!Anyway, I decided to replace the power jack. No hard job, just a simple unplug and plug back in job. (looks abit like this Hp power jack image by chikyeung on Photobucket). I replaced it; everything is running fine. I tried to put a USB pen drive into a usb socket. Didn't work. Tried another, didn't work. I have tried several devices and they all work on other computers but don't seem to be working on mine. I have been trawling the internet for answers, and as of yet, nothing -.-! I wouldn't call myself a novice, trust me, I've tried everything, uninstalling and reinstalling all of the USB drivers, checking bits of the registry.etc. Nothing. So today, i thought, right, WIPE THE COMPUTER! I backed up everything, went back to scratch.

Jul 25, 2012My LAN and WiFi suddenly stopped working. It was working fine for several hours before now. I decided to take a break and pour myself some coffee and give a package to the postman. Gone for maybe 10 minutes at the most.When I came back, the LAN and WiFi mysteriously had stopped functioning. I know nobody touched anything because I am the only one who uses this computer. I tried disabling and re-enabling, as well as re-installing the drivers. This is a work network, and everyone else's connection seems fine, and I can't seem to figure out what's wrong. Keep in mind I can't just re-set the router because this is not a home network.

Aug 16, 2010The first thing I do after installing win 7 is apply the uxtheme patch. I've been running custom themes for a while, but yesterday decided to change the look of things. I applied a os x leopard type theme, it didn't work and now I've lost all desktop visual effects (transparency, themes, win+tab).I run the diagnostic and it detects that 'Windows Desktop Manager is disabled' - so I think "Ok, I'll just go into services and re-enable it"... but it's GONE! How the hell can a service just remove it self?So I run System Restore back to when I knew it was working, but still no damn transparency, that service or themes, just the default non-transparent Aero!
