I had a motherboard fail with a similar set of symptoms.
Mine was due to bad capacitors on the motherboard itself.
Take a look and make certain that none of them are swollen
or pushing material out the top.

Heat also leads to random resets - is your fan still running
smoothly or is it covered in dust and cat hair like mine..?

Best of luck - hope this helps,
