What you've never understood about your computer is that it is scared to death of water, H2O, humidity or whatever you'd like to name it. & even though you do not see the water, actually there may be lots of excessive moist in the air killing your motherboard silently & slowly. No, your motherboard doesn't melt when in contact with water like the wicked witch of the west, but it dies of short circuit. Luckily, ASRock has a High Density Glass Fabric PCB design that reduces the gaps between the PCB layers to protect the motherboard against electrical shorts caused by humidity.
