• Blue screen after installing the driver for windows phone 7

  Hi all

  I installed the new version of Zune. When I connect my Windows 7 phone (HTC Mozart) to my computer (Vista SP1), the driver will install automatically. After that, he tells me to restart. When I do this, and when windows starts again, theres a BSOD with the following message:
  Driver IRQL not less or equal
  This only happens when I installed the driver for my phone.
  Once windows restarts and gets me to error checking etc and after that, it tries to start Windows again go through the process of "update configuration". Naturally the updates are not properly configured, and it restarts and tries to restore changes. This pretty much goes in a loop forever, until I restart, run in safe mode.
  I have no idea why what is happening, and search on Google did not help so far. Any help would be appreciated.
  Thank you.
  Euler

  The minidump files show the recent errors are errors IRQL_NOT_LESS_OR_EQUAL (a) and the cause of the error is OA001Vid.sys.

  The OA001Ufd.sys also seems to be involved in the accident.

  These two drivers seem to be the drivers for the integrated webcam.

  What you might try is the next update for the webcam to the laptop:

  I bought a new hard drive. Re-install my windows 7 Home premium. I had no internet drivers so I install those wireless of my acer site. Still miss me driver, and now with my internet windows must be able to update. Whenever I hit the update via the web it says it's impossible. I don't know what to do because the acer site does not have the same names of those that I'm missing. His two drivers work of frame and the ethernet driver.

  If family win7 premium shipped preinstalled with Acer, did not create the recovery media according to the instructions of Acer, which would have included all the drivers?

  Updates of .net framework are not drivers

  All the required drivers are obtained on the Acer support site, specific to your model

• Random BSOD after installing the drivers of port replicator.

  Hi, my boss has just got a new laptop (TP T400s running Windows 7) and after setting up the it, it worked great. But then I installed the drivers for the port replicator with digital video and after the reboot, just after the login screen, USB ports it BSOD, complain igdkmd64.sys. Restarted again, he has not crushed during his connection this time, just a little while later, when clicking on the start menu. After several tests, the Replicator seemed to work, but not the digital video port. The DVI connector did not work correctly, just the mouse pointer has been posted. Try setting the resolution did nothing and switching output source through Win - P causes a strange flicker for a minute or two and then the machine automatically rebooted. Tried the driver found on the CD (1.0) and also those that are available via the Lenovo Web site of (1.5.6.8), always the same thing. Now, I uninstalled the drivers and the random BSOD keep reappearing.

  This problem is common? The duplicator is defective or is it the ThinkPad? The windows installation is screwed, peut it be repaired? What is the Lenovo return policy?

  I saw many complaints on this forum about random stop, it would be unacceptable to us that the current BSOD we meet a few. This is common?

  P.S.: We try to get the job done, not beta-test of Lenovo products!

  Thank you

  The driver win7 for Replicator usb with digital output is not released yet. So, you can not get it work under win7. I remember seeing an official brochure of the product, in which there is a line indicating that a win7 driver will be released in December.
