No more BSOD, replaced memory working fine. System much better than before with Netflix - it might stutter, but audio doesn't start breaking up as it did on my old system.

I got one more BSOD, and running BurnInTest revealed 1 error. Decided to pull 8GByte of the memory and return to 1600 clock. 300 errors with BurnInTest even before it timed out. Swapped to the 2nd...

The smaller Samsung drive failed the long generic test; I ran chkdsk and found it detected bad blocks. Would this be the cause of crashing?

System crashed, then had one of my drives start clicking, like the disk drive click-of-death. Thinking it was the new 3TB drive, I removed it, put it on an external USB adapter and it was working...

The 'network card' is the motherboard. I do have a spare DLine network card I could try instead of the onboard one.

Another crash: DRIVER_IRQL_NOT_LESS_OR_EQ in NETIO.SYS

First BSOD after a while of running fine. This is a new build PC with a clean install of Windows 10. It crashed a lot after installation, then settled down.

Today, I'm running a download installer...
