Hi whatdyaaa.

All your recent BSODs are stop 0x76, which is a driver failure.

Most of the crash dumps are silent about the probable cause, but some of them are identifying BitDegender Active Virus Control filter driver as the failing/crashing element.
BugCheck 76, {0, fffffa800e9a2060, 177, 0}

*** WARNING: Unable to verify timestamp for avc3.sys
*** ERROR: Module load completed but symbols could not be loaded for avc3.sys
Probably caused by : avc3.sys ( avc3+232ed )

Uninstall BitDefender. At least as a test.
How to uninstall Bitdefender

Use Microsoft Security Essentials as your antivirus with windows inbuilt firewall, and free MBAM as the on demand scanner.

Let us know the situation.
