Try and change the PSU.

I found out some PSU, when getting older, don't provide as much power as 
they used to do.

Disk tests will work because they stress one disk at a time, but when 
all disks work together, they'll choke due to not getting enough power.
Also memtest86+ checks memory when all other components are idle: again 
when disks and CPUs start playing, the memory banks may fail due to 
insufficient power.
