I had a similar problem recently. I added memory and although the system
passed memtest in all possible DIMM configurations, it was unstable,
frequently hanging just as you describe. On the occassions that it did
boot, the system showed errors when running the mprime torture test. As it
turns out, the solution was to up the Vdimm voltage in the BIOS, but I did
not do this until I checked the memory manufacturer's website to verify
warrantied voltages, etc. Probably worth a shot.
