Okay.

Okay.

AIUI microelectronics are now so small that an electrostatic discharge 
too small for people to notice may still be large enough to damage the 
electronics.

Okay.  Please post the information when available.

Okay.

Okay.  Please post the information when available.

I would run Memtest86+ for 24 hours first.  If it fails, replace the 
memory module with a known good module and run Memtest86+ for another 24 
hours.  If that fails, I would blame the motherboard.


If/ when your memory is good (and CPU by proxy), download the 
manufacturer diagnostic tool for your system drive and run that. 
Consider wiping the system drive.  I prefer bootable USB images.  For 
example:

Once your CPU, memory, and system drive are known good, then do the install.
