Any ideas what this might be?
I was having a crash with instant power down. So I replaced the PSU with a Xilence, and for a while all seemed well. Then it happened again. Restarted. But to restart, I had to actually unplug the power cable. Only then did the power switch work.
All carried along fine for a week or so - I never turn it off, and ir ran just fine. Then just now, it happens again!
In the meantime afflicted by a sudden rush of nerves I have made a backup using clonezilla so its not going to be the end of the world if it goes south.
What happens is, try to use the power switch and nothing whatever happens. Then I connected up to a different power cable and a different socket, and it goes on. The Gigabyte board asks me to pick the last good boot, so I do. Then it powers down and restarts, and goes into the usual Debian login, after which it runs the disk diagnostic and repairs itself, and now its running just fine again.
What on earth could it be and what should I do?
See what is weird is that I am tempted to think maybe its the extension block, but the screen runs off that, and that is just fine. It seems reasonable to change out the extension block because they are not expensive. But I can't quite see how that could do it.
There is no doubt that last time it was the psu. It was totally dead, and replacing that first with the evo and then with the xilence, it did actually bring it all back to life. But this time its clearly not the psu, or could it be?
