I'm using SoftPerfect Ramdisk 3.4.6 on Windows 7 Professional SP1 32 bit.
Recently when my computer tries to hibernate after some idle time, it will show bluescreen with code 0x9F (DRIVER_POWER_STATE_FAILURE).
I suspect the drivers of the ramdisk may be the cause, so I use verifer.exe to check them by creating custom settings (for code developers) and selecting all drivers not provided by Microsoft.
(Well, I'm not familiar with driver develop at all, I just try that from an article on the web.)
After restart, BSOD 0xC4 (DRIVER_VERIFIER_DETECTED_VIOLATION) comes and it says spvve.sys is the cause. Then I select spvve.sys only in verifier.exe, and after restart BSOD comes again, but if I choose any other drivers, no BSOD.
BTW, if I use DATARAM ramdisk, there's no issue when computer enters hibernation state.
So, would you please help test that and see whether spvve.sys will cause verifier.exe to BSOD in your environment? Thanks!
