With current hardware prices you are probably better off just replacing
anything that doesn't work right, especially intermittently because
you'll never know when you can trust it. I wasted a lot of time with a
machine that had a RAM problem (took days of memtest86 to show it) and
even after it was fixed the problems kept popping back up as the
alternate copy of raid mirrors were read.
