  Audio drivers appear to be there and working, the drivers are inheritance this is just? It looks like a conflict somewhere. I went from Vista after network problems now XP has sound problems.

  Ideas please

  Hi David

  I ve checked your other assignments created here in the forum and it seems that you are an owner of Equium A100-027 PSAAQE series.
  Am I wrong?

  First of all, I would like to clarify a few things.
  Especially the yellow exclamation points appear in the Device Manager because anything could go wrong during the driver installation procedure or you have used everything simply a bad drivers.

  I think you first need to know if you have used the correct drivers!
  Please go to the page of the Toshiba driver and check again the driver versions and download again.
  I noticed that many users download the bad drivers and try to install it.

  On the Toshiba page, you will also find installation instructions. There are 2 txt files.
  One for XP and one for Vista.

  Please make sure you use the appropriate for the good OS installation instruction.
  Download all the drivers, then follow the order of installation mentioned in the txt file!

  Normally, everything should work ok and you should be able to install any drivers!

  Best regards

• Pioneer BLU - RAY and DVD discs not recognized by Windows 7

  The discs were fine until I installed Windows 7 Home Premium 64-bit. Before my hard drive crashed, I was using Windows 7 Pro 64 bit. The computer was built by a local store, so I don't know if they have done something special to get discs running, but readers are reported as compatible with Win 7.

  Readers are:

  PIONEER BDR - 205 Blu - ray

  DVD PIONEER DVR - 218L

  My motherboard is ASUS P6TD Deluxe, BIOS 0106

• Stor.e slim not recognized by Windows 8.1

  Hello

  A Stor.e slim external HARD drive is not recognized in Windows 8.1 (no problem with Windows 7). When it is plugged in, it s shown as a device not recognized. Driver is requested but not found.

  Hello

  Stor.E Slim external HARD drive is a 2.5 HDD USB 3.0 and 900mA power it requires to work correctly.

  I suppose that there is nothing wrong with this HARD drive, but with your laptop.

  8/8.1 win requires different drivers and you will probably need to install a suitable driver in order to get the USB ports work correctly (USB 3.0 as well as the driver additional chipset would be also necessary).

• Yoga Pro 2 - display not recognized in windows (hardware or driver problem?)

  Out of warranty by a month!

  Yoga Pro 2-256 gb, installed a new wireless card a month ago. Windows 8.1

  The touchscreen still work while the screen is black.

  System restarted after the mode 'sleep', in my opinion.

  The Lenovo logo is displayed, seems to load Windows, but when windows loads (I don't see it so it is a hypothesis of load) drafts of the screen and the black light is on.

  Can I connect an external monintor that connects after the return from sleep mode (odd). Who then off the backlight.

  When the external monitor, the internal screen is not yet recognized by windows.

  When I boot in safe mode, the internal display works fine with of course limited capabilities.

  I rebooted on the support site display drivers.

  Right now my internal monitor is not recognized by windows and is dark, and I can use an external monitor.

  Someone at - he of the clues as to what my happen? Hardware, driver etc?

  Can what information I provide?

  It is a pretty weird problem with contradictory observations.

  (1) screen working in Mode safe but not regular boot. (So not the hardware problem)

  (2) display on an external monitor in normal mode. (So, no drivers issue)

  Have you installed the wireless card yourself? You unplug the cable from the screen during the installation of the card?

  Could you re - open and check that all connections are good?

  The Wi - Fi card works well?

  I also recommend a complete reset of the laptop to eliminate the possibility that it is a corrupt driver. You can use the NOVO button to reset your laptop. Make sure you make a backup on an external drive for your personal files.

• HP Laserjet P1102w: HP Laserjet P1102w not recognized in Windows 8.0; driver needed

  Trying to install HP Laserjet P1102w on Dell desktop running Windows 8.0. The installer always stops and says to connect the printer by USB, but it is already connected and turned on. Had to remove peripheral devices after he worked temporarily, but now I can't find the driver - have the disc. How to recognize the driver on disk file?

  Hi @artjourneyer,

  I see that you have problems get printer recognised and you will need to find the file on the CD for the printer. I will definitely do my best to help you.

  The file would be .inf from the CD.

  I would say to download and use the latest drivers for Windows 8. HP LaserJet Full Feature software and driver.

  Turn on the printer and make sure that the printer is connected directly to a wall outlet. (do not use a hub or a surge protector) This ensures that the printer is full on and can help this situation. The USB cable should not be more then 6 feet. Make sure that the USB cable is connected directly to the computer. (not a station or a hub) Try a different USB port on the computer. You may need to try another USB cable.

  Try and print a self-test on the printer hardware to see if it is a hardware problem. If the printer is not in a ready state, the computer does not recognize it. Printing a Configuration Page. Select the method two.

  This can occur when the printer is already recognized as the USB connection and windows does not yet detect. Remove the USB cable plugged in, remove the printer from the Device Manager.

  To access the Device Manager:

  Press the windows key and press X on the keyboard at the same time in the office.

  Then click on Device Manager in the list.

  Verify that connections in Device Manager for the entries of the printer, under Bus USB controllers look for a USB print media or anything with an exclamation yellow, storage device or an unknown device. Right click and uninstall the device.

  Then reconnect the USB cable and it must be detectable again.

  You set up the printer on the wireless network?

  If you appreciate my efforts, please click on the "Thumbs up" button below.

  If you have any questions, please let me know what steps you have taken and the results. Thank you.
