pefect computer stability

[Baby Astronaut]

Is there any modern PC or supercomputer design built so reliably that it doesn't ever go "blue screen", crash, or have glitches of a sort (where you must reboot it every now and then)?

 

Or if so...does every computer have a back-up system no matter how flawless its performance?

My computer is perfectly stable... When it's off!

tends to be software that causes 'bluescreens' and so on.

There's an operating system kernel that can be mathematically proven to do exactly what it should do:

Microkernels make a big effort towards greater stability by providing the bare minimum of services in the kernel and splitting everything else up into "daemons" that can be restarted easily if they crash.

 

Preventing user-space software (web browsers and such) from crashing is much harder, since the software is often huge (millions of lines of code). You can put as many safeguards in the operating system as you want, but you can't guard against programmers accidentally making the program do the wrong thing.

"prefect stability" is an abstract term, every OS no matter what has or has the possibility of having "stability issues". this, comes from many vectors; such as, poor hardware, an example would be a cheap mouse, or cheap video card. and poor drivers, etc these types of issues cause more problems then not.

 

also, software, 3rd party software added to your computer thats poorly written and or does things sloppily. also, causes issues. or, even things like AntiVirus software that adds things to the kernel. causes issues.....

 

all, OS's have these problems.... if, you want a very stable system, get good quality hardware, and load the OS yourself from the OS media not a restore CD.

 

now, security is a different matter do not get me started on that....
