If it's a hardware-related issue, as Scott suggested, you can spend all the time you want fiddling around with the software and you'll never solve the problem.
Yes, you'll almost certainly end up swapping it out anyway, either all at once or piecemeal (power supply, memory, motherboard, etc.). It's probably not worth the time to try to diagnose it. Working hardware should stay up for years.
