As mentioned in the title,
Which part is responsible for the processing speed, that PC demanding programs work faster and that the system itself works faster?
How to determine if an upgrade of this part is possible?
Probably the processor, if no one is in it, just push glucose into the SD slot for the little man who is struggling…
That would be pretty much all parts (except the "funny flashing LEDs", etc.).
All components work together. However, one can say that e.g. When playing graphics card and process are important. However, one should not leave other components outside, then too slow a working memory can also become a bottleneck.
If you want to open programs quickly, a good hard drive should be used. There you should not, for example, put an HDD as a system hard drive, with an SSD you are better off.
Essentially bus, CPU and RAM - that must fit together.
The main sticking point is often the programming - a CPU with multiple cores and threads is of no use when it comes to an application that knows how to use only one thread.
And programs that swap / reload a lot run better the faster the transfer rate from / to mass storage or network.
You can determine whether an upgrade is possible by finding out whether there are components that fit the system and whether they actually improve performance.
It depends on what the program needs. The CPU does most of the calculations, but when it comes to 3D graphics (or calculations programmed for a graphics card), that's important too. The data must come to the CPU (faster working memory) and if it is an application that requires a lot of working memory, it is important that it is also large enough… Because if the working memory is full, modern PCs continue to calculate but write the data to the (much slower ) Hard drive which then slows everything down. When the PC starts, programs or games are loaded, a lot of data has to be processed one after the other that does not fit in the RAM, etc. Then everything depends on the hard disk or SSD. Then there's the mainboard, the components of which connect all of the things mentioned above.
Sometimes there's a single component that slows everything down, a bottleneck, bottleneck. Someone who knows his stuff can find that and replace it with something better, yes. But generally it depends on what you want to do.
Therefore, programs and games also have minimum requirements and recommended requirements. They should all be fulfilled so that it slips well.
I need tuning "on-button".
Wasn't there a website where you could download more RAM?
They were bought up by Apple…
So "funny flashing LEDs"? ^^
Well, what comes to mind: Technically speaking, the "power on button" is nothing more than a button, that is, a switch that is closed as long as it is held down.
You can tap 3.3V, 5V and / or 12V from a ATX power supply of your choice.
So:
Install a button that closes the switch contact and starts the system.
+ 5V and GND from the power supply to the Arduino Uno / Nano built into the housing.
… ArDuInO-MaGiE… Blinking lights, small texts / mini graphics on various LCDs / OLEDDs, a pong game that is operated via two buttons on the outside of the housing, possibly a program that is loaded when the system starts and signals the Arduino "Hello, i bims 1 operating system from PC. " (including corresponding flashing signals and screen outputs of the Arduino), etc.
Finished.
Motion detector sensor module and Arduino… And now the PC is on when I enter the room: -D jup, that saves whole seconds.
Then the Arduino needs an energy source that is largely independent of the PC.
Possibly. A built-in power bank and control electronics that switch to ATX mode when the main system is switched on.
Here is my idea:
Input of the PB at + 5V and GND of the PSU.
GND from PSU, Arduino and PB in ne 3 → 1 terminal.
Take a switch relay module and clamp the VCC of the Arduino to the middle output.
+ 5V of the PB to the NC of the relay, + 5V of the PSU to NO of the relay and (if necessary via an optocoupler / NPN / etc. To an input of the Arduino.
Wait on the Arduino for the input from 4. To supply the value HIGH (if necessary also simply by interrupt) and switch the relay as soon as this is the case.
(Optional) Clamp a "large" electrolytic capacitor between the VCC and GND of the Arduino to have enough juice when the PC is switched off to switch the relay back to PB. (UPS style ^^)
Alternative: Activate the relay directly via the PSU. (Possibly use one with 2 channels to inform the Arduino of the current status.)
Another idea: Arduino + PIN pad + LCD + relay = enter code to start PC. ^^
