This initialises the RAM and the PCI bus.

The CPU begins executing the Power On Self Test (POST) in the BIOS or UEFI code. This tells the motherboard to release the reset line, which allows it to return to +5V.

This puts the CPU into a known start state, with default values loaded into all the registers, and sets the instruction pointer to the start address of the BIOS.īetween 0.1 and 0.5 seconds later, the voltages from the PSU have stabilised and it signals this by putting +5V on the Power Good line. Pressing this button signals the motherboard to tell the power supply (PSU) to fire up and pulls the voltage to 0V on the reset pin for the CPU.

When your PC is switched off but still plugged into the mains (or laptop battery), the motherboard still receives power on the 5-Volt standby rail, providing power to the circuitry that monitors the power button. If you can complete a sudoku you can learn Python.

You can learn the basics for free in a few weekends at Google's Developer website. Python is a good language to learn first – it's a widely used, serious language, but designed to be readable and simple. Happily, programming is easier to learn now than ever. Programming is such a useful skill that it should be compulsory for all five-year-olds, never mind aspiring Tech Gurus.

And if you can write even a modestly useful app or a mod for a game, then your computer itself will be demystified to a degree that's impossible to overstate. You can teach yourself to strum some chords without it, but you won't become a great musician that way.Īs soon as you can write a simple program, more complicated programs lose their mystique. Programming is like classical music theory for computer troubleshooting. Programming means debugging, and the mindset you for it is the same as for diagnosing every other computer problem. When you understand how the house is built, you'll know which walls you can safely remove and which will bring the ceiling down on your head. It's a collection of discrete integers and floats and strings. Memory isn't just a quantity, like the fuel in your tank.

Programmers are like Neo: they don't see files and icons, they see resource handles. Lots of command line operations become easier if you know a little programming, particularly in Linux – but much more importantly, it teaches you what a computer really is. Programming is an extremely helpful skill for a Tech Guru. This is useful for novice users.Learning Python is straightforward, useful and free Learn to program If the applied settings lead to unstable operation of the graphics adapter and there is a high probability of a «fatal outcome», the program can automatically reset everything to the factory standards. Then you can start a new selection of settings for the current video card. If the settings are too high, the program will reset everything to the factory standards. This way you can avoid critical consequences. The program allows you to check the frequency settings before applying them. We urgently need to reduce the core and memory frequencies in this case. The program monitors the current parameter in real time and issues a corresponding warning if a critical point is reached. During overclocking, the core temperature increases significantly. In case of failure, you can kill not only the video card, but also the entire motherboard.

However, you need to experiment with this carefully. Increasing even a few steps can make the graphics card work much faster. The frequency of the memory bus of the video card also affects the speed of the graphics adapter. But without a good cooling system, you should not do this. This increases the overall performance of the graphics adapter. The program allows you to increase the operating frequency of the core (of course, within adequate limits). The core frequency is exactly what affects performance in the first place.
