Tracking down random BSOD on windows 7
- by pehrs
I have gotten a computer running windows 7 handed to me that randomly, several times a day, bsods with a PAGE_FAULT_IN_NONPAGED_AREA (50) or WHEA_UNCORRECTABLE_ERROR (124). Crashes happens regardless of load. I am running out of ideas for how to track this down.
Analyzing the minidumps shows the crash to be in ntkrnlmp.exe/WMIADAP.exe
System has plenty of power (600w)
Ram checks out fine using memtest86+ over a weekend.
System is clean inside. No dust build up. Temperatures stay low.
As far as I know (and reliability history shows) no new drivers were installed for several months before the problems started. All drivers are now up to date.
sfc /scannow reports the system as clean.
CHKDSK reports the disks as clean
Removing the AV (Avast) has no effect.
Any more things that should be tried on windows 7 before I start replacing the hardware?
