Death of a motherboard?
I am hoping to get some insight from someone who would have had a similar experience.
The situation is the following:
We have a computer that has been working for quite a while. Low power i3 3GHz, nothing fancy. One day it never came back from sleep, the motherboard seemed dead.
Thinking of a power glitch, I changed the motherboard, the power supply (Corsair 430W) and the power bar (APC). The motherboard is a Gigabyte H61-USB3 mini ITX; no card is inserted in the PCIe slot; video comes from the i3.
The computer died again about 4 hours after the switch. If power is applied to the board, LEDs are not turning on (well, slight single blink when power is applied showing the PSU is doing its job) but nothing else.
I am trying to figure out how this could be possible. USB ports are full (except 3.0 ports) but that is it.
Could a power surge do this? Go through power bar and PSU to hit the motherboard this hard? The scanner (old HP SCSI scanner) is still alive and well and is plugged to the very same outlet.
Could it be the CPU? (only thing left to change)
