I bought a TV back in 1973, it would turn off after a while
and not work again for an hour or two. Took it back several
times to get it fixed. I'd get a phone call saying it was
working. The store didn't want to refund or replace it
since their shop (in-house Sears) didn't find anything wrong
with it.
I finally took it in and actually demanded to see the lead
technician so I could explain the problem so they would not
just plug it in and turn it ON, but would duplicate the
problem. It took about 24 hours, but they found the problem,
a cracked circuit board.
When it got hot the board would expand and the printed
circuit would move a few thousandths of an inch. When it
cooled the circuit would come back together. A little
solder fixed it..
You could have a similar problem on your mobo or a video
card, even the RAM. There are several ways to check for
cracks using dye tests, spot cooling, magnifying glasses or
a heat gun used carefully.
