I've been suffering from repeated BSOD for a month or so. Very strange in that there doesn't seem to be a pattern for when they occur. They are all Kernel Data Inpage Errors.
Examining the error dump files with the Windows debugging tool, it seems this is "typically caused by a bad block in the paging file or disk controller error".
So I downloaded HD Tune Pro, and it is showing S.M.A.R.T errors in two categories for my Crucial M4 system drive. (05) Retired Block Count (also known as Reallocated Sectors Count) shows 24,576!
(C4)Reallocation Event Count shows 6 and also seems to warrant a notification of problems.
I've done what I can to eliminate any other possible sources for the BSOD's. Virus scans show nothing. Ran chkdsk. Went back to a saved image from months ago, when I know for certain that there were no problems in the system. Operating system is fully updated. New drivers for various types of hardware have done nothing. The system is not overheating, and in fact has been doing very well in video encodes for hours upon hours of 100% CPU use. Windows Memory Diagnostic and MemTest 86+ have shown no errors in memory.
There is no common program being used when the BSOD occurs. It even did it while idling, with nothing except background services going.
So, it looks like a hard drive beginning to fail to me. I've requested an RMA from Crucial, but haven't received a confirmation email from them yet.
The M4 does have the latest firmware. Any other ideas?
