How do you troubleshoot a motherboard?

Answer 1

If the motherboard powers up but does not post, turn off and remove the memory sticks then restart, if the board is good you should get beeps from the board

letting you know that the board has a memory error, if no beeps then it is possible

the processor is bad, get a known good processor and if still no beeps then then the motherboard is toast

Answer 2

It depends on the issue. I am not going to explain them all. I will explain the most common. If the motherboard will not power up, check for loose cables, make sure it is plugged in. inside the computer check for burning smells when the power butten is pressed, always test the power supply with a power supply tester. Turn on the lights and when you plug it in or flip the main switch on the computer does the lights dim. If you see any popped capsiters or black streaks or discoloring on the motherboard, smell smoke then usually the motherr board is fired. Also when you plug it in, if you get a LED light lit then that means its getting power but dosent mean in the right places or the its not broken.

The most comman sythems of a fied motherboard is the light dims when power is brought to it, you smell a bunt smell when the power butten is pushed and its makes a high pitch quit squeek when power is lost or unplugged.
