Solution
Error Causes
The stop error 0x00000050 signifies that there’s a PAGE_FAULT_IN_NONPAGED_AREA problem. If you’ve seen this error on different occasions then you will find the parameters in the message to be varying. That is because they are dependent on your PC’s configuration. Not all Stop errors "0x00000050” occur due to a single issue.
However, the most common problem which is encountered which results in the stop error popping up is due to a pool corruption occurring in the Srvnet.sys file.
This issue might be caused because of software incompatibility or a defective physical memory which resulted in requests for data for a hardware driver or service which was not found in the memory.
If you find the error occurring after you’ve installed a new application or a device driver then you should access Safe Mode and uninstall, disable or remove that application or driver.
