BSOD 0x09F, happens on shutting down and at random times

[Twiglight]

This is my second post the first time it was, seemingly, resolved but the problems came back. Now the BSOD happens almost everytime I try to restart/shut down my laptop, and it happens at seemingly random times. The first time I got these advices:
uninstall avast! and update bios I did this and the problems were gone for about a week but recently they have been coming back, does someone have any ideas to solve this?

My information

Windows 7 is
- x64
- original installed OS
- an OEM

- What is the age of system (hardware)?
I bought my laptop in the summer so i think it is approximately 7-8 months
- What is the age of OS installation (have you re-installed the OS?)
I did not change this so about 7-8 months.

Did you update your BIOS?

I see you went from AVG to Avast. As indicated last time we recommend you install MSE in its place at least till you have resolved you problem.


Most recent crash is from Feb 28. Have you still been crashing?

I have updated my BIOS already and I have installed MSE already avast! and AVG are long uninstalled and the most recent BSOD was actually today but the minidumps don't show up in the minidump folder, and I don't know why. Any ideas?
