Intermittent problems like this are often hardware-related. I'd start by
running a RAM checker, at least overnight, and then testing your
filesystems thoroughly.

Remove and re-seat (not just push down on) all cable connectors

The fact that this occurred just after a hardware change makes it even
more likely you have some sort of H/W problem.

Maybe that's not your trouble, but it's always a warm fuzzy feeling to
be certain your hardware is working properly.

BTW - The fact that a machine ran Windows without problems does NOT
prove the hardware is OK :-)
