BSOD sometimes after i turn on my computer, sometimes just random BSOD

Hi julianiscool.

One of your crash dumps reports some malfunction of Avast. Uninstall Avast using Avast Uninstall Utility. At least as a test. Use Microsoft Security Essentials as your antivirus with windows inbuilt firewall, and free MBAM as the on demand scanner.
Though I am in doubt that the issue is really caused by Avast (sometimes it does), it is better to remove it as it is flagged.

Also test your RAM modules for possible errors.

Run memtest for at least 8 passes, preferably overnight.

If it start showing errors/red lines, stop testing. A single error is enough to determine that something is going bad there.

Let us know the results.
