If you suddenly find that your Windows desktop PC will not turn on, take a look at this useful guide to get an idea as to why it is mis-behaving.
We've listed the most common reasons why your PC may not turn on here and added a little explanation to each reason.
The first thing you should do is check all of the connections behind the machine. That includes the power, the keyboard and mouse, the display and any other connections you may have.
Here is a handy diagram of the most common ports on the back of your PC. Check that all of the cables you normally have plugged into these are in nice and snug.
Failing power supply:
If you press the power button on your computer and it does turn on, but suddenly shuts off again, you may have a failing power supply. In this case you will need to bring it in to us so that we can replace it for you.
Your PC turns on, but there is nothing on the screen and the box is beeping at you. This is your computer telling you that there is something wrong with the hardware.
Your computer will beep in a certain pattern. Each pattern is actually a specific error code, telling you which part is not working. There are hundreds of possible combinations across all of the makes of computers, so if your computer is beeping at you, get in touch with us and we will diagnose it over the phone for you.
If none of these apply, try booting the PC in safe mode. You can find instructions for this under our guide for booting in safe mode here
