Windows will not boot with a Stop Error 0x0000007B

A very common BSOD (Blue Screen of Death) is a STOP error 0x0000007B and may indicate either a hardware, software or driver issue.

Please see the great troubleshooting guide put together by Tim Fisher on about.com

One thing that Tim does not mention is that sometimes it is necessary to slipstream the AHCI SATA Controller Drivers into your Windows XP or Windows Server 2003 installation media.  This can easily be done by downloading and using nLite to slipstream drivers and updates into your Windows XP or Windows Server 2003 CD Media, you can get the application from http://www.nliteos.com/

Common AHCI Sata Drivers include:

Intel – http://downloadcenter.intel.com (Look under Chipset, Chipset Software and then Intel Rapid Storage Technology.  You will need the F6 Drivers for either x86 or x64 depending on you using 32bit or 64bit windows)

Nvidia – http://www.nvidia.co.uk/Download/index.aspx?lang=en-uk or http://www.nvidia.com/Download/index.aspx?lang=en-us

AMD/ATI – http://support.amd.com/us/Pages/AMDSupportHub.aspx

Verify the Health and Operation of your Intel® Processor with the Intel® Processor Diagnostic Tool

A 32 and 64 bit version of the IPDT or Intel Processor Diagnostic Tool can be downloaded from here: http://www.intel.com/support/processors/sb/CS-031726.htm

You can also see a video on how to use it here: http://www.youtube.com/watch?v=tpPOqh_Bq78

You can use the diagnostic tool to test the various features of your Intel Processor and perform a stress test to ensure that it is operating in a  stable manner.

A Windows Based Computer that is connected to your network via an IP Phone (NAP-Enabled) may not connect to the same VLAN after resume from hibernation

This issue applies to Windows XP – SP3, Windows Vista – SP2, Windows Server 2008 – SP2, Windows Server 2008 R2 – SP1 and Windows 7 – SP1.

This issue occurs on networks that use IEEE 802.1X authentication where the client computer or server machine is connected or bridged via a NAP-Enabled device such as an IP or VoIP Phone Handset.

The issue will not be resolved for Windows XP because it is now outside the mainstream support cycle.  Hotfixes for the other operating systems listed above can be obtain via Microsoft KB 976373 http://support.microsoft.com/kb/976373

Windows Vista and Windows 7 – USB Audio Device or USB Headset can cause High CPU Usage and you may notice skipping in the sound playback

If you use a USB Headset, USB Speakers or USB Sound Card under Windows Vista or Windows 7 you may notice that the CPU Usage is very high when you are listening to sound, music or gaming.  You may also notice that the audio lags or skips as a result, this will normally occur every 10-20 seconds and may get worse over an extended period of time.

This is most likely to occur when the device is connected to a USB 2.0 EHCI (Enhanced Host Controller Interface)

The issue is caused by a problem with the usbport.sys driver that is part of Windows

The issue can be addressed in Windows 7 or Windows Server 2008 R2 by upgrading to “Service Pack 1”

The issue can be addressed in Windows Vista – Service Pack 2 or Windows Server 2008 – Service Pack 2 by applying the hotfix from http://support.microsoft.com/kb/981214 which includes an updated version of usbport.sys
