1) Motherboard doesn’t recognize/show peripherals. Although the problem can lie on the hardware itself, it can actually be the symptom of a motherboard that is going bad.
2) Peripherals will stop working for a few seconds or more.
3) Slow boot-ups could indicate that your motherboard is going bad, though it could be other components as well.
4) Computer won’t recognize flash drives, or monitor sometimes shows strange lines
(particularly relevant if you have onboard video on your motherboard).
5) Motherboard doesn’t POST (Power on Self-Test).
6) Burning smell or burn marks anywhere on the motherboard itself. If you happen to notice a burning smell emitting from your PC, then you should immediately turn off the computer. This means that the motherboard inside the PC is already overheated to the maximum and should not be used anymore. Despite of this if you continue using the motherboard, it can affect other components as well. Usually this caused when incompatible components are connected to the motherboard resulting in short circuits.
7) Bulging or leaking capacitors. A failing motherboard most at times shows of physical damages especially the capacitors bloated out. When the motherboard starts overheating, the capacitors present on it will be enlarged than usual. This is more common in old motherboard models since they are prone to overheating. However, a blown capacitor can be easily replaced but under some conditions. This requires precision soldering.
8) Computer freezing is another symptom of a failing motherboard. This can happen all of a sudden when you are working with your computer. But not all the freezes and glitches can be pointed towards the motherboard, there can be software problems as well.
However, if the freezing happens to occur frequently there are more chances the issue is related to the motherboard.
9) Blues screen of death. This is typically occurring when there are hardware problems. But there can be other variety of reasons too. For finding whether the blue screen of death is related to the motherboard, you can actually search the error code in google so that you can see if it relates with the motherboard. Even if after troubleshooting the error seems to reappear then the issue can be with the motherboard.
10) Beep Noises. Generally, when a motherboard encounters failure it will indicate then through a pattern of beep codes. In case if you can’t boot your computer at all, listen for the pattern of beeps given by the PC. Most likely if the pattern is followed by 3, 4 or 5 it is a sign of a failing motherboard (beep patterns vary depending on different motherboard
models). If the motherboard is already dead there will be no beep codes given at all.
