We have a CPA client running Windows 10 Pro with 1909 updates. For the past two weeks, he is getting a BSOD with PFN_LIST_CORRUPT message. One day last week he got two BSOD in one day and then three days without the error and one BSOD today. We had other customers with a similar issue after updates KB4524244 and KB4532693. Removing these updates appeared to resolve the other client issues but not for the CPA client. The removal was based on an internet article about Windows 10 issues after the updates around February 17.
We are asking for any suggestions for software or hardware for troubleshooting the PFN issue. This is a very busy time for all CPAs. Getting a BSOD in the middle of a tax return could result in the loss of several hours work. We have found several solutions such as checking RAM, hard drive, and drivers but would like any suggestions before starting the list of items to check so we can minimize any possible downtime of the computer. If we get replies pointing to a certain solution, we would like to use that as our next step.
Thanks for any suggestions or comments on resolving this issue. Please let us know if more specific information is required. IMG_2817.jpg
We can post an update when we can get access to the client's computer.
