I changed the mouse
I changed the keyboard
I changed the power supply
Always the same - at random, 90% of boots (however done) give dead mouse
Then of these 50% give dead keyboard

It seems you have tried lot to rectify this problem

Why do'nt you try Hair dryer with your PC

It seems Motherboard has caught moisture, due to this it takes time to restart.

Have you checked in the Device Manager to see if there are any problems there?

Are you having trouble with just an initial boot (after the computer has been turned off), or with a reboot as well?

Have you run ScanDisk lately? It would be best to run it in Safe Mode, but if you have trouble rebooting, it may not be the best way for you.

My thinking about the earthing is that on turn-on various transients are going on (like degaussing of the screen) which put MAX strain on an earth connexion. I do not have eqpt to measure the pulse-impedance to earth.

Or it may be common-impedance in the supply wires (say due to the "surge protectors" they sell here in uk. Will have to find out how they work - e.g. series inductors in the wires?

The device manager says everything is OK (However it said THAT about my CD R/W that demonstrably was not wkg!)

The fact is EVERYTHING IS WORKING once you get it to turn on! (Even the CDR?W now I have a new one in).

NOw restarts, reboots and initial boots.
With the old power supply restarts (hot reboots) were frequent and reliable.
Cold starts got progressively more difficult. (Cold is defined as "From a zero power-on state")
With the new power supply ALL cold starts (except the very first) have been desperate nerve-shattering affairs lasting unpredictable hours! But since the new power supply there have not (yet) been any warm reboots.
I understand that in a warm reboot one of the power lines (5v one? 12v one?) stays on. So MAYBE my trouble is this line is NOT turning on quickly enough in a cold reboot?
(One power line (12 v one) MUST be on "all the time" to operate the on/off switch)

Following your suggestion I tried to run scandisk. It is NOT there - as confirmed by doing a start-find-search (or whatever they call it)
HOPWEVER during my traumatic adventures TRYING to start MANY TIMES it said (among many other things) "We need to check your hard disk" and went ahead and did it.
Many times it found "nothing wriong".
Many (other) times it found and "corrected" several things (orphan files etc)

Thank you so much for your persistent help and not giving up!

What an interesting idea! Very sensible and probable too! The winters here in UK are very damp, and we do not dry out with central heating like the Yanks

So next time it shuts down on me (say next month) I will try the drying-out idea before I waste 4 hours trying to restart.
Thanks fot a GREAT idea!
Very probably explains why the new power supply, straight from its box, DID work first time (but never reliably during turn-on since). But once on, keeps all dry by its warmth.

Wow......
Talk about the "Blind leading the Blind!!!"

It never ceases to amaze me how such mindless people are allowed to jump on the internet and use their stupidity to make someone else's problems worse.

The reason the Keyboard and Mouse won't work is because the power supply is TOAST and he needs a new one.

Also, the definition of Insanity is: is doing the same thing over and over again and expecting different results.
So if your PC is not working properly, don't turn it on & off for 2 hours straight hoping that the Computer Gods will help you. That's not only insane, but just plain stupid!

Get a new power supply dude. And the rest of you who have NO FREAKING CLUE as to how to answer his question: DON"T ANSWER ANY MORE QUESTIONS IN REGARDS TO COMPUTERS FOR THE REST OF YOUR LIVES!!! you people are USELESS!!!!!

First of all, you MUST turn your computer off. I suspect that you are severely overheating your motherboard, and it's about to fry.

I am having the same problem, with my kb going dead all the time. USB. Wondering if anyone else could help with that? AMI/ASUS motherboard.

I said the same thing. Their motherboard is def toast. Wondering if you could help me with the same problem though. I have an ASUS MB, and my keyboard keeps going dead. Has something to do with the USB drivers, I am sure, but I have uninstalled all USB devices, have reinstalled them, and same thing. over and over again.
