I've read your first 5 errors. One did not give anything specific as to the cause.
Two that are of definite interest is the 0x8E error that are almost always caused by hardware and are particularly a strong indicator of corrupted memory. The minidump only cited hardware as the cause.
The other error is 0x7E: SYSTEM_THREAD_EXCEPTION_NOT_HANDLED
A system thread generated an exception which the error handler did not catch. There are numerous individual causes for this problem, including hardware incompatibility, a faulty device driver or system service, or some software issues.
This one specifically cited corrupted memory as the issue, thus a hardware issue.
The other two errors cited the drivers navex15.sys and SYNTDI.sys which belong to your Symantec/Norton internet security software. We have seen many people having issues with this software.
However, due to the cited memory corruption along with your random BSODs it is first and foremost suggested that you run Memtest on your RAM. See this link and follow instructions:

Let it run for a LONG time. The rule is a
minimum of 7 Passes but more is quite okay. There are 8 individual tests per Pass. Many people will start this test before going to bed and check it the next day.
If you have errors you have corrupted memory and it needs to be replaced.
Also, with errors you need to run this test per stick of RAM. Take out one and run the test. Then take that one out and put the other in and run the test. If you start getting errors before 7 Passes you know that stick is corrupted and you don’t need to run the test any further on that stick.
