Hi,
We have a few different bugchecks attached here:
BAD_POOL_HEADER (19)
Usual cause is a device driver has a bug.
This indicates that a pool header is corrupt.
Your *19 appears to be faulting iusb3xhc.sys which is the Intel(R) USB 3.0 eXtensible Host Controller Driver. Ensure this driver is up to date via -

^^ Netgear Neutral Wireless Solution dated from 2007. See if an update is available -

DRIVER_IRQL_NOT_LESS_OR_EQUAL (d1)
A kernel-mode driver attempted to access pageable memory at a process IRQL (Interrupt Request Level) that was too high.
Usual causes are a device driver has a bug and attempted to access invalid memory, the pagefile has been corrupted or there is a memory problem.
SYSTEM_SERVICE_EXCEPTION (3b)
An exception happened while executing a routine that transitions from non-privileged code to privileged code.
This bugcheck is generally related to a video driver issue.
Ensure you have the latest video card drivers. If you are already on the latest video card drivers, uninstall and install a version or a few versions behind the latest to ensure it's not a latest driver only issue. If you've already tried the latest version as well as many possible previous versions, you can try a beta driver if available.
If the above do not help, enable Driver Verifier to see if we can catch any possible device driver conflicts:
Driver Verifier:
What is Driver Verifier?
Driver Verifier is included in Windows 8, 7, Windows Server 2008 R2, Windows Vista, Windows Server 2008, Windows 2000, Windows XP, and Windows Server 2003 to promote stability and reliability; you can use this tool to troubleshoot driver issues. Windows kernel-mode components can cause system corruption or system failures as a result of an improperly written driver, such as an earlier version of a Windows Driver Model (WDM) driver.
Essentially, if there's a 3rd party driver believed to be at issue, enabling Driver Verifier will help flush out the rogue driver if it detects a violation.
Before enabling Driver Verifier, it is recommended to create a System Restore Point:
Vista - START | type rstrui - create a restore point
Windows 7 - START | type create | select "Create a Restore Point"
Windows 8 -
Restore Point - Create in Windows 8
How to enable Driver Verifier:
Start > type "verifier" without the quotes > Select the following options -
1. Select - "Create custom settings (for code developers)"
2. Select - "Select individual settings from a full list"
3. Check the following boxes -
- Special Pool
- Pool Tracking
- Force IRQL Checking
- Deadlock Detection
- Security Checks (Windows 7)
- Concurrentcy Stress Test (Windows 8)
- DDI compliance checking (Windows 8)
- Miscellaneous Checks
4. Select - "Select driver names from a list"
5. Click on the "Provider" tab. This will sort all of the drivers by the provider.
6. Check EVERY box that is
NOT provided by Microsoft / Microsoft Corporation.
7. Click on Finish.
8. Restart.
Important information regarding Driver Verifier:
- If Driver Verifier finds a violation, the system will BSOD.
- After enabling Driver Verifier and restarting the system, depending on the culprit, if for example the driver is on start-up, you may not be able to get back into normal Windows because Driver Verifier will flag it, and as stated above, that will cause / force a BSOD.
If this happens, do
not panic, do the following:
- Boot into Safe Mode by repeatedly tapping the F8 key during boot-up.
- Once in Safe Mode - Start > type "system restore" without the quotes.
- Choose the restore point you created earlier.
If you did not set up a restore point, do not worry, you can still disable Driver Verifier to get back into normal Windows:
- Start > Search > type "cmd" without the quotes.
- To turn off Driver Verifier, type in cmd "verifier /reset" without the quotes.
・ Restart and boot into normal Windows.
How long should I keep Driver Verifier enabled for?
It varies, many experts and analysts have different recommendations. Personally, I recommend keeping it enabled for at least 24 hours. If you don't BSOD by then, disable Driver Verifier.
My system BSOD'd, where can I find the crash dumps?
They will be located in C:\Windows\Minidump
