My Win Pro X64 system has been humming along pretty nicely for a few years, but lately I've been getting blue screens approximately every 31 minutes or so. But only when it's "idle"; never when I'm doing something like typing or browsing the net or running a local program.
Bluescreenview shows clfs.sys and ntoskrnl.exe, and it says it was caused by clfs.sys, mostly CLFS.SYS+a649 or occasionally CLFS.SYS+3e73e.
Things done so far:
Inspected event logs; mostly information level stuff. There are many 1001 Bugcheck reboot events over the last two days and I see no issues in the log before the reboot.
sfc /scannow (multiple times, no integrity violations)
chkdsk /f /r
memtest (2x4 Gb modules, each tested separately)
Uninstalled programs, including avast AV, startup problems galore
Haven't done much with driver verifier, one time it resulted in me having to restart in safe mode to disable it. I let the computer sit for a while in Safe Boot Minimal and it did NOT crash. So I started removing drivers from boot. Removed all non-MS and Intel drivers. Still problems. At that point I had an additional entry in my minidump - HECIx64.sys - along with clfs & ntoskrnl. So after doing a bit of research to see if it was safe, I disabled that Intel driver as well as the heciservice. Left the machine on overnight and no BSOD so I re-enabled all my startup programs and previous disabled drivers, keeping the heci stuff disabled. (I did not reinstall Avast). No BSOD. I ran with this configuration with a day or so and then started getting the CLFS / NTOSKRNL BSODs again.
This is a very consistent issue in that something is going on every approximately every 31 minutes to cause the crash.
I have attached perfmon and filecollection (I did remove all the minidumps except for the most recent, as they are all the same) for my normal startup configuration. The only other change from my normal config is that last night I unplugged all USB devices except for the keyboard (I normally have a scanner, a Focusrite sound/recording device, Midi keyboard, and an old SimpleShare nas plugged in.)
Would appreciate any advice on what to try next as this is my primary home machine.
Thanks.
