Shutdown vs Restart

post #1 of 10
Thread Starter 
I was under the impression these two did the same thing with the exception of restart automatically rebooting once powered down.

I mean my PC goes through a complete post as it would if i had it off for 10 minutes. Is there any true difference as I got into a little debate with my co worker on this. By the way he calls the tower a hard drive smile.gif

Shutting down interrupts power, and resets memory devices to default.

Restarting does not interrupt power, or flush memory devices.

Wouldn't memory devices just be overwritten as the system reboots and all the processes reload.

Also it has to interrupt power to some aspects as a lot of my stuff turns off when i restart then starts back up. What parts remain powered, the mobo i would imagine is the only thing that truly is left powered.

And what is the difference between this and the residual power left in the pc when you shut it down. As i know that if i unplug my psu and then hit the power button it discharges some electric as the computer attempts to come to life for a split second.

Those follow up questions are a little more detailed than I can answer, sorry!

I'm interested to see replies though, I'm not too aware of exactly how the memory interfaces work for the hardware, nor the specific properties of the power system at different times.

I'll tell you in 6 months when I'm taking my hardware CIS course, haha.

Doesn't shut down clean up the cache that you build up from using the PC, while restart might or might not do that?

OT: where are you in NYC?? Join the club in my sig tongue.gif

To detailed for me too lol. Appreciate the responses. I am still sticking with the fact that a shutdown then power on will provide zero benefit to just restarting. In fact i have only encountered the opposite where i had a video card issue with cold booting and it never gave me problems when only restarting lol.

Power is cut from the RAM in a shutdown. In a restart, the memory remains "warm" and it is not ensured to be flushed before boot. In addition, if you restart via Windows I believe the POST process is usually skipped and adapters are not reset.

So yes, there is definitely a difference. If troubleshooting a hardware issue I would always recommend a complete shutdown in order to insure all memory is flushed, adapters reset and power cycled.

to each his own, they basically do the same thing, except a restart is ever so slightly faster, and requires less initial power cause some things have power already.
