Before I continue I have a short and relevent anecdote for you...
It's sometimes noisy where I live, what with the nieghbours horses, lamas, donkies and cockerel's and the fact that there is an army training ground at the end of my road. There are almost always aeroplanes flying back and forth. So loud you can't hear anything else and so low the whole house shakes. When we came to view this property, before buying, I had a word with the nieghbours...
"So what's it like living here then?."
"It's really quiet, just the way we like it."
After we moved in and I found out what it was really like, I said to the nieghbour...
"You told me it was quiet here, what about the planes, the army and the animals?"
"Oh yes, well, you get used to them"
(Monday Oct 15 2018), there has been a developement. It was quiet here, which allows me to tell you something about my PC. As of this morning, when I switched the on my PC there aren't any light's and absolutely no sound's.
Further to this, I noted something else that I really don't understand. I have 3 PSU's the one that was in the PC when all this started (850w), the one that used to be in this PC before I upgraded (750w) and one I took out of an old gaming machine (300w). They all worked when last used. However, now I know that the (850w) isn't working, niether is the (750w) and weirdest of all neither is the (300w). I tested them all this morning, by plugging them directly into the mains socket, but without the first or the last one being connected to he PC. How could I tell that they weren't working?. Because none of their fans were moving.
I have a large selection of power leads, but after I tried to start all the PSU's with four or five leads (to no avail) I gave up. So I imagine the fault lies (oddly) with all 3 PSU's and not the power leads. when I plug anything else into the power socket they immediately work. So it's looking increasingly that I won't be getting a new case and MoBo just yet, but perhaps another PSU instead?.
