Curious, is there a possible fault in the power supply that could cause power surges to the hard drives? I think, silly me, the house current is eliminated leaving a connection or possibly loose part in psu?
I'm attempting reason with insufficient knowledge, due apologies. Puzzle time.
Since reason in this case is eqrivalent to WAG is there any significance to the HMDI socket ceasing to work (if it isn't monitor, since it still works on vga?), if its the socket not the monitor?
Don't know current draw for GPU, shouldn't affect psu?
