I just built a new Ryzen machine on an Asus B350 board with a .5 TB SSD and 4 TB HDD. I've been experiencing random system hangs, where Google can't access its cache, I can't save, etc -
feels like the system stops responding but the mouse keeps working - and I've finally isolated the problem to the SSD, based upon incidents like this on in Resource Monitor (http://imgur.com/6HaZzzL):
I ran chkdsk - no errors, looks fine.
I swapped out the SATA cable for another, made no difference.
I am not sure what else to do to diagnose the cause, if this is a bad drive or something about the motherboard (which is admittedly new). The 4TB drive doesn't get accessed nearly as much, so I haven't seen the same problem with it yet.
