    Strange issue on pc with asus motherboard not sure whether to change the board or try just changing the processor first as cheaper option ?
    Basically the fault is very intermittent but it will keep shutting itself down ( a random controlled windows shutdown usually after 30mins not just a sudden loss of power )
    and then restarts itself several mins later and then repeats the process randomly ??
    I believe the issue has to be either the motherboard or processor as I have tried 2 different PSU ( was confident this was going to be the issue ) however this fault persists after changing PSU.
    So my question is do I order a board or a processor ?

    Can one of these items cause a controlled shutdown and then a random restart sometimes several mins after shutting down ?
    It has become most annoying because sometimes it can behave itself fine for several hours but is always present if left for 7 / 8 hrs and then switched on again from cold.

    motherboard is a ASUS F1A115-M LX Socket FM1
    I have also tried a new hard drive with a fresh W10 installation to ensure software not the issue.
    Bios flashed to latest version and have also changed bios battery.

    So can a faulty motherboard or processor be the cause of this fault ?
    thanks again guys for your valued comments :confused:

    Hi LatinMcG

    Thanks for the quick reply.
    Yes I too suspect the board as obviously it is always powered even when the PC is switched off so I assume some how its self starting and self shutting down randomly.
    Its most annoying as the symptoms indicate its a PSU fault but this is not the case :(
