Capacitor or IC on motherboard failed.
I checked my ASUS X99 Pro motherboard with the new Zalman Aircooler. Suddenly, a capacitor or IC failed, showing smoke before I powered it off. It still works when I try to turn it on. Is it safe to keep using it? What should I do to fix it without replacing the board?
This could involve several options, including a linear regulator or transistor. It seems likely it's a standard linear design, so checking the package label would be the simplest method—though burning might make that harder. If you spot similar components, you can identify them more easily. Another approach is to look at a high-resolution PCB image and examine it closely, though this isn't always reliable. A third option is using a multimeter to analyze the circuit; if it functions, you might continue using it. Keep in mind a computer may power on but not be fully stable. Before testing the motherboard, consider stress-testing the entire system.
If done properly and with the correct part, then yes—provided nothing else was harmed.
