True. I was thinking of it coming under the heading "swap components
until it works again", but it doesn't hurt to mention it explicitly.

It is possibly easier to try a different supply from another computer
instead of swapping cards.

Another one I heard recently is that SATA DVD drives, when faulty, can
interfere with and stall the boot process. Pull off SATA cable, try
again.

Btw I found memtest86+ to be only so-so. If it flags an error there is
a problem, but if it doesn't it means absolutely nothing.

Basically, good luck. If the lockups are only every month, or every
week, it's impossible to find the problem. Any fault that can't be
triggered can't be fixed (other than by total replacement).
