Hello,
My computer won't turn on anymore; everything was normal and it was working perfectly the last time I used it, this is very sudden... I used a different power cable but still nothing. One thing is certain, the power is not reaching the central unit.
Can you help me? Thanks in advance.

Good evening,
"The current can no longer circulate"... Nothing lights up? No lights or fans spinning?
If so, it's either the power supply that's faulty or the motherboard or an external card (I've experienced this with a faulty graphics card that must have had a short circuit, and as a result, the PC refused to start with the card, but without it, there were no issues, and with another card too).
Google is your friend.

Hello,
As previously mentioned, either the power supply has failed or the motherboard or a PCI card.
To test the power supply, you need to open the PC, then remove the largest connector from the power supply (20 or 20+4 pins), then using a paperclip, connect the green wire to any black wire (it's not always the green wire on older power supplies; you need to check the label to see if PS-ON is indicated and what color is specified).
Once done, plug in the power supply and see if it starts.
You can also try with another power supply from another PC or you can test the power supply with a power supply tester (there are cheaper ones: http://www.ldlc.com/fiche/PB00066394.html).
If the power supply starts, it is OK.
So if the power supply starts, remove any cards connected via PCI/AGP/PCI-E (graphics card, sound card, modem, network card...).
Check for any faulty capacitors (bulging or leaking), then plug in and turn on the PC; if it works, it means it's an external card causing a short circuit; otherwise, it's the motherboard that is faulty.
