Anyway, I started unplugging things one at a time until I got the the 4 pin power connector for the processor. Once this was unplugged, the machine would stay on with no problems. I told him that it looked like a problem with the power supply, so we ran to Best Buy and grabbed on off the shelf. Hooked it up and it had no problems.
Fast forward about 2 weeks. He told me this morning, that the same thing is happening again. Try to turn it on and the fans spin for a second and the machine turns off. Anyone have any idea as to what the problem might be? The machine functions flawlessly other than this unusual problem.
