How many have experienced cpu failure--of any kind? Of those that have, how many could be attributed to some form of radiation degeneration of the cpu (or memory)? Much harder to access as without extreme analysis, there is simply no way to know.

I have experienced failure which, after extreme analysis, we could only attribute to radiation degeneration of a byte of memory - see Re: What do you know, and how do you know that you know it? for some details.

Later in the same job I was writing interrupt handlers for a new ARM-based chipset, and found a problem in that chipset - a bug in certain (characterisable) situations when a multiple-register store instruction crossed a 64k page boundary. Somehow that did less to shake my confidence in the perfection of hardware than the memory corruption problem.

    One was random, one was not. Very understandable.

    ... after extreme analysis, we could only attribute to radiation degeneration ...

    A somewhat less than definitive causality. But assuming that you are correct, that's 1 in n*100e6 computer users.

    I'm still inclined to believe that disk failure is probably more common :)

[marto]: xubuntu or lubuntu
[Corion]: :-D
[marto]: my desktop is a core2 duo, 120GB SSD, 4GB RAM, boots to (GUI) login in less than 10 seconds from cold start
[Discipulus]: mah, winbuntu 10...
[marto]: whent he boys start school I'll build myself as new machine, ryzen based
[Corion]: marto: That's cool! I think my (home) desktop spends 30 seconds in the BIOS...
[Corion]: marto: Heh - currently they seem promising, but I think I'll stay with nVidia+Intel for the time being, as I've been bitten too often by bad AMD drivers
Discipulus is (still?) not a big fan of notepad++
[marto]: Corion, I think in the past this was a big problem for them. GPU driver wise the improve all the time. I use the open source drivers on my machine (old R9 270, 2GB) and had no problems
