Based on the fact that the 64 bit version I was using is now fully corrupted and unavailable from Miscrosoft, it may be possible it was not a good file I used to install the software. I saw that one of the other senior members posts a like where I could get a good download of MSE, so I'll try that.
As far as the stability of my comp, I'm running in exactly as I was prior, just without MSE or any other AV and I've not had any crashing with downloading or playing videos yet. I did have a random restart without a BSOD, so no crash dump, but the event logs showed the following:
Session "Circular Kernel Context Logger" stopped due to the following error: 0xC0000188
The maximum file size for session "Circular Kernel Context Logger" has been reached. As a result, events might be lost (not logged) to file "C:\Windows\system32\WDI\LogFiles\BootCKCL.etl". The maximum files size is currently set to 104857600 bytes.
At the time of this restart, I was putting a large amount of data from a compressed folder into my C drive.
I really don't know what this means, but when I googled it, I saw that it could be further issues with the motherboard. I'm already leaning towards RMA due to the possible issues with the LAN port, so I'm wondering if this is further evidence of MB problems.
