  I have an Acer Aspire 7750 running windows 7 Home premium. When I insert a flash into the USB drive, I hear the sound that indicates the flash drive is inserted, but the drive does not appear in the window 'my computer '.

  Check if the same works in different USB Ports, in Device Manager if there are any unknown devices or try to uninstal and reinstall USB Root hub, that should help you. Let know if you have the same problem. You can also check with all other USB devices if works.

  Original title:-drive Flash USB port does not appear

  I have laptop Dell A 4 years and cannot use USB ports. My data flash drive lights flash but nothing shows up in 'MY Computer'

  It turns out that there is a problem connecting to the motherboard... so it ' s not worth repair. However, I believe that I can connect to the Internet by the yellow cable supplied with the router.

• Combo DVD/CD drive does not appear in Windows Explorer or the Device Manager

  The combo DVD/CD on my laptop drive isn't in Device Manager or Windows Explorer.  The door is not ejected.  You must use a paperclip, poking into the hole to open it.  I also re - it sitting, but it changed nothing.  We had this laptop for 1.5 years and the disk worked great until yesterday when trying to install Starcraft II.  Installation failed and it has messed up also the DVD/CD drive.

  We read some other difficulty advice and tried the upper and lower filters in the registry, but there was no entires of upper and lower filters in the key.

  Step 1: Please do all the same underneath if you did some before as is often total
  a process that solves the problem.

  Try this - Panel - Device Manager - CD/DVD - double click on the device - driver tab.
  Click on update drivers (this will probably do nothing) - RIGHT click ON the drive - uninstall.
  RESTART this will refresh the default driver stack. Even if the reader does not appear to continue

  Then, work your way through these - don't forget the drive might be bad, could be a coward
  cable or slight corrosion on the contacts (usually for a laptop) and other issues.

  Another possibility is that the cables are loose. Remove ALL power, then make sure that the cables in both

  Some DVD players do not use the Windows default drivers so check with the manufacturer of system and

  ===============================

  Step 2: You have disc problems as the CD/DVD is actually 4 discs in 1 case (CD & DVD
  Burn and CD and DVD read). So it is not unusual for 1 or 2 operational so that other parts
  do it right.

  Did you follow the Troubleshooting Guide for the reader who still does not work? There are

  Check with your Maker system and a device for the two possible firmware updates and

• product key does not match current Windows SKU

  I completely rebooted my laptop using the recovery DVD and completed the recovery process until the windows implementation required me to type my windows product key. I typed the key that was on the label of my computer case. However the phrase 'product key does not match current Windows SKU' is displayed. What should I do?

  Hi Michelle,

  Thanks for posting your query on the Microsoft Communities.

  I'm sorry to know that you encounter some problems using the product key. Let me try and help you with this question.

  Did you purchase this license from a merchant reseller?

  There are several reasons to why you get this error:

  > You made the it.
  > The product key you entered does not match the key assigned to Windows on your computer. The SKU is waiting for a key matching the installed version
  > The product key has already been used on another computer.

  If you are still having the same problem, then please contact Microsoft Service customer to confirm if the product key is the right one for the current version of Windows 7.

  How and when to contact Microsoft and support Customer Service

  Hope this information helps. If you have any other questions, we will be happy to help you.

• Windows 7 key does not match current Windows SKU

• "My external hard drive does not appear in Windows Explorer and cannot open 'Help and Support', an error message" Windows cannot open help and Support because a system service is not ongoing.

  Original title:

  Everything was fine until yesterday. Juice now, when I plugged the external HD into the USB port it does not appear in the 'my computer' window. It is recognized by the computer as it is present on the list of the "Disk Clean Up" and it also appears when I click on ' Safe Remove Hardware ' on the taskbar. But if she does not appear in the 'my computer' window I can't work with it or don't even know what it I have arquived in it.

Pops up a window saying that "Windows cannot open help and Support because a system service is not ongoing enforcement. " To resolve this problem, start the service named help and Support '. OK, I tried to open 'Help and Support' ' Start Menu ' and the same window appeared again to "not have a system service that runs". I don't know what her soul precisely and I have not the slightest idea of what I need to do to correct this 'disappearance' of Service 'system '.

• USB microphone does not work with Windows XP

  I have problems to make my USB Plantronics Gamecom headset mic works - be when the headset is plugged into USB port, or directly into the sound card. I think I checked all standard solutions: Windows OS updated, update driver for Plantronics, SB Audigy 2ZS Sound card driver updated, its mixer configured to capture a USB device to record the sound/voice and sound/voice playback (except when it is connected directly to the sound card, then I have this option is selected) , microphone not cut with setting the sound card and the "secret" on the micro iteself button is not on.

  Should there be an option to adjust microphone levels when I click "Open volume control" on the volume icon in the taskbar (lower right corner of the screen)? This option does not appear.

  Thanks for any advice you can give me!

  Norm

  Hello Norm58,

  I suggest that you install the drivers for the Plantronics device and check if it is enabled in the playback devices.

  a. Click Start, type Sound in the box to start the search.

  b. click sound in the results of search at the top of the start menu.

  c. click the Read tab.

  d. on the tab 'Read' it has listed the sound options at your disposal. It should read "The plantronics device" click on it.

  e. There should now be a checkmark on this option.

• CD/DVD drive does not appear in Windows 8

  My CD/DVD drive no longer appears in Windows Explorer in point 8.1 of Windows on my desktop HP Pavilion Slimline 400-034. The disc rotates during startup. I tried the troubleshooting of Microsoft Window 8 with no luck. I would try the HP troubleshooting which requires access BIOS when booting, but by pressing F10 at startup me does not BIOS but Windows load normally. Any suggestions to at least help me get the BIOS?

  Solved! No. thanks to HP. Even if I had never opened the file on my PC and make sure that the cable DVD could not be disconnected, I decided to look for. Much to my surprise, he has been disconnected - but not by me - by a HP technician. I remembered that I had to return the PC to HP to replace the power supply warranty in June 2014. Not only have they not reconnect the cable SATA DVD, they put the cable from the hard drive in the MB connector where the DVD cable was supposed to be. After trial and error and insert the DVD cable in the 3 open SATA connectors with no luck, and finally move the cable from the hard drive to another connector and put the cable DVD where the cable from the hard drive was, the DVD has been recognized by Windows and working correctly. Thanks to HP for the many hours I lost to try to correct their mistake.
