Bug Check 0xC5: DRIVER_CORRUPTED_EXPOOL
The DRIVER_CORRUPTED_EXPOOL bug check has a value of 0x000000C5. This indicates that the system attempted to access invalid memory at a process IRQL that was too high.
Important Info If You Have Received a STOP Code
If you received a blue screen error, or stop code, the computer has shut down abruptly to protect itself from data loss. A hardware device, its driver, or related software might have caused this error. If your copy of Windows came with your computer, call the manufacturer of your computer. If you purchased Windows separately from your computer, Microsoft provides support. To find contact info for Microsoft or your computer manufacturer, Contact Support.
If you have experience with computers and want to try to recover from this error, follow the steps provided in the Microsoft article Resolving STOP (Blue Screen) Errors in Windows.
These actions might prevent an error like this from happening again:
- Download and install updates and device drivers for your computer from Windows Update.
- Scan your computer for computer viruses.
- Check your hard disk for errors.

Cause
The kernel attempted to access pageable memory (or perhaps completely invalid memory) when the IRQL was too high. The ultimate cause of this problem is almost certainly a driver that has corrupted the system pool.
In most cases, this bug check results if a driver corrupts a small allocation (less than PAGE_SIZE). Larger allocations result in bug check 0xD0 (DRIVER_CORRUPTED_MMPOOL).
Resolution
If you have recently installed any new software, check to see if it is properly installed. Check for updated drivers on the manufacturer's website.
To debug this error, use the special pool option of Driver Verifier. If this fails to reveal the driver that caused the error, use the Global Flags utility to enable the special pool by pool tag.
For information about the special pool, consult the Driver Verifier section of the Windows Driver Kit.
