Sometimes the problem can be mechanically affected. You can try using
an insulated (e.g., a plastic pencil with rubber eraser tip) rod to
press around and tap the chips and a few places on the PCB. Sometimes
there are bad solder joints that can show up this way and these often
are affected by temperature as well.

A CPU substitution might be a good idea if you have another unit. Be
sure and check the CPU voltage settings too.
