Mac Pro 2,1 unexpectedly shuts down and restarts
Mac Pro 2,1 shuts down without warning and restarts, the normal Apple "chime" plays and the Mac starts back up.
One problem that exists is a bad DIMM Riser -- the "B" DIMM Riser doesn't recognize RAM, could this be the root of the shutdown?
MacPro 2,1
Quad-Core Intel Xeon 3GHz
8GB RAM
OSX 10.6.8
Thanks for any direction.
