Hello,

 

My laptop ACer Aspire 7720 is a little old now, 9 year old, but it has performed well, taking account of its age, until now. It started BSOD-ing 4 days ago, after trying updating its drivers  while it bsoded all the time and restarting I removed the battery (which btw doesn't hold more than 2min). It seemed not doing it for a day while starting again the next one. It is worth sharing that one or two nights prior to the crash I changed the power mode to never sleep while plugged in cause I installed a waking app for it to wake me up in the morning and than changed the settings back. Than it started bsod-ing a lot.

 

P.S 20 minutes ago I changed the power plan to saving mode and it hasn't crashed yet.

 

Here attached the requested files

 

Thank you for the answer

Hello, arsita,

Here's my analysis of the latest dump file (all of the recent ones are similar).

As you know, you had a STOP 0x0000009F: DRIVER_POWER_STATE_FAILURE bugcheck, indicating that a driver has failed to complete a power IRP within a specific time.:

0: kd> .bugcheck
Bugcheck code 0000009F
Arguments 00000003 89b11030 83331ae0 898025e0
The fourth parameter of the bugcheck is the address of the blocked IRP. Let's inspect it.
0: kd> !irp 898025e0
Irp is active with 9 stacks 8 is current (= 0x8980274c)
 No Mdl: No System Buffer: Thread 00000000:  Irp stack trace.

Ah ha, so a third-party driver seems to be the culprit! It's a decade old and was probably not intended to be installed on Windows 7:
0: kd> lm k vm snp2uvc
start    end        module name
82e1b000 82fcb200   snp2uvc  T (no symbols)           
    Loaded symbol image file: snp2uvc.sys
    Image path: \SystemRoot\system32\DRIVERS\snp2uvc.sys
    Image name: snp2uvc.sys
    Timestamp:        Mon Oct 01 02:59:45 2007 (47009AE1)
    CheckSum:         001BB7AD

    Translations:     0000.04b0 0000.04e4 0409.04b0 0409.04e4
Therefore, please reinstall your Suyin USB 2.0 Webcam driver. If issues persist, physically remove the webcam from your system.
