PC restarting on it's own.

Bollox. Of both the Utter and Fucking kind. Totally, I will let you
get away with as I don't know if the op has any knowledge of his own but
although I doubt it I am going to give you the benefit of some.

If you don't know what metal the plating is (assuming there is any) then
use the rough side of a piece plain white copier paper. Amazingly
abrasive on stuff like gold and silver edge connector plating it is.

 

Well, as mentioned its a technique thats worked fine for me for the last
15yrs.

If you use paper or a rubber then there is always a chance of leaving some
residue behind.
The most important thing is to make sure what ever you use to clean it,
ensure none none of it falls in the connector slot.

No it hasn't, you have left a legacy behind you. Besides it is worth
remembering that effectively paper is free and available everywhere,
gritty rubber ain't and you do want to be seen to be implementing cost
effective solutions don't you?

See, you are getting desperate to save face now aren't you. It won't
work you know.

 

Err.... no, my 386 is still running fine as a word processor for my aunt.
That was an MCA machine that had its SoundBlaster card and memory cleaned
this way.
Plus, the cirrus logic cards we cleaned had a below average field failure
rate.

No, not really, but thanks for asking.

 

May still be a hardware problem. Molly suggested the memory.

I suspect this has something to do with the technologies we are used to
working with. When I cleaned a contact it was on a machine where it
was expected I would clean it such that it would stay clean for 50 or
more years. Yours *will* be in the bin in 50or less months. I was
trained to perform a permanent fix, not one that had just had to outlast
a vase full of flowers. Different innit?

 

Indeed I do.

 

At Ericsson, we used to call that "slam and jam", cured a lot of faults
on an AXE10 anyway.

 

Which is what we're talking about here - PC's.
I don't know anyone who will keep a PC for 50yrs.
The PC has a refresh cycle of at the most - what 6 - 10 years at an extreme.
No matter what the contact is, or what environment its in, it will end up
tarnishing thru heat, or oxidising thru exposure ? Surely ?
I wouldn't of thought any contact would stay clean for 50yrs without being
hermetically sealed, greased or varnished, which doesn't do much for its
conductivity properties ?

 

As daft as it sounds, is the CMOS battery still ok? My Mum's computer
was doing the same thing a couple of weeks ago, I initially thought
that it might be the PSU or similar. When I checked the computer, we
were apparently living in the year 2019..

I replaced the battery, and voila, no more problems.

Yes/no. Depends dunnit.

Your modern PC edge connector is going to be covered in just enough gold
to be put together once or twice. A microscopically thin layer probably
laid down an atom at a time. Short life cheap shit innit? Don't rub it
too hard.

I was involved in the first roll out of wrapped (rather than soldered)
joints for the GPO in this part of the world. I had a course and
everything on it I did, All sorts of interesting facts about how
surfaces apparently "just in contact and bugger all else" can appear to
weld together over time and present a lower electrical resistance with
age. Lots of sums and graphs and stuff. Very pretty it all was and
very plausible too. I believed it, still do really.

 

Interesting reading here ....

I bow to your years of knowledge working with comms cables, but the method
as described by me works for me and has so far not let me down.

Not just comms. Don't rub too hard.

 

Yeah I had that a couple of years ago

No idea what it was - it cured itself

Is it networked and has it decided to go into wake up on LAN mode

...
Useful, aren't I ?

 

Sandblast the bastard - teach it a lesson
