It sounds like it could be a heat problem. Leave the case off and see if
all fans are working, especially the CPU fan.  If so then try directing a
portable fan directly into the case with the case open.  I had an
intermittent problem like that once and it turned out to be a CPU fan would
sometimes not startup.
