• CD/DVD drive not detected in 'my computer '.

  Ok.  That is the problem.  A few weeks ago, I couldn't find my CD/DVD device in 'my computer '.  I read the solution involving the modification of the registry.  Scary stuff, I know, but I did everything very carefully and removed the filters superiors and inferiors, and Wallah, it worked and my CD/DVD device appararurent again and I was able to open a CD and look at the files.  The same thing happened again, but when I look at the registry fix again he has no less and the top filter to remove.  I ran all kinds of diagnostic tools Microsoft Mr. Fix and after execution, gently, he finally tells me "the CD/DVD device not detected.  Well, DOH!  I already knew!  But how to fix it? I have a HP laptop with a build in the drive.  When I put a CD in the tray and close it I hear all the normal whirring etc of the currently playing disc, but nothing happens.  Absolutely nothing - a bit like these emails that promise miracles that if you pass them on to 10 people, absolutely nothing happens.  Please help - in non-technical terms please.  I am a user of the computer, not a grumpy, instructions must be simple.  Oh, I must add, after reading other topics of the forum, my tray works perfectly.  I can load and unload CDs.  Finally, my CD/DVD drive IS NOT doesn't appear in Device Manager if no suggestion re clicking on the disk or drive in Device Manager.  IT is NOT THERE.

  You have loaded CD/DVD programs just before this started happening? Often those who will compete
  for resources that load themselves into memory and the interaction parts cause strange problems.

  Check with HP Support, their drivers and documentation online and ask in the forums known HP

• Satellite L755D - Web cam/mic are not detected by Skype

  Good evening everyone,

  I just noticed that when I install and open Skype, my built-in webcam and microphone are not detected by the application. He has worked in the past, but I've not had to use Skype for more than a year, so never noticed until now.

  I checked the Device Manager and there is no webcam or microphone listed. I tried to search for new hardware, but it found nothing.

  Specifications of systems:

  OS: Windows 8.1 Pro
  Processor: AMD A8 - 3500M
  Memory: 8 GB of RAM (2 x 4 GB Kingston sticks)
  HARD drive: 750 GB Seagate Barracuda
  The version of the BIOS: Insyde Corp. 2.10 (28/06/2012)

  If any other info is needed to help diagnose and solve this problem, then please ask and I will provide.

  Thank you very much

  Michael

  I guess the laptop not was not preinstalled with Win 8.1 but updated you the Win 7 system to Win 8.1.
  Is this correct?

  I m application because it would be interesting to know if the webcam worked correctly using Win 7.
  The driver for the webcam using Win 7 to be installed to get the webcam recognised.

  To help to win 8.1 additional webcam driver is not necessary because it s already part of the Win 8.1 System. That is why the webcam should appear in the Device Manager without installation of the webcam driver.

  However, some models of laptop supports additional webcam POWER setting in the BIOS.
  Please check this option in the BIOS.

• HDD and dvd are not recognized in the configuration menu, what could be the problem?

  The hard drive and dvd drive are not recognized on the configuration menu for my desktop Pavilion a4316f.  What is a controller failure?  A PCI controller can be used to replace the motherboard controller?

  dhobs,

  Anguish, that the suffering of the faulty motherboard has been aggravated by your actions. Why you decided to perform a restore (which re - formate the disk, erase all your data files (documents, photos, videos to misic,) is really amazing.)

  You had a viable BONE, work and the data store. You he clobbered with recovery. As explained, the 'tattoo' reads the embedded hardware configuration and will stop at the resumption of treatment if it detects a change.

  Only temporary help I can offer is to open the computer case and install a small 12v on the NVidia chip fan. IF the chip is not 100% burned, you can earn low enough time to reinstall the operating system and then add the map.

  You can probably find more info here and maybe even the exact registry for your CD/DVD settings
  drive from someone with the same model.

  Use DevManView to locate the CD/DVD in the registry (be careful and do a prior Restore Point)
  nothing change) - find the DevManView device and then make a right click on it free in RegEdit.

  DevManView - free - an alternative to the standard Windows Device Manager, which displays all the
  devices and their properties in flat table, instead of the tree viewer

  I hope this helps.
