Hello all,


I brought my PC with me and it doesn't seem to like Europe lol


I used the very same setup in my country where the voltage was 110. Here the voltage is 220. My PSU is a Corsair GS600, its tag says it handles from 100V to 240V.


I assembled the PC, it turns on, the bios gives a short beep, the hard drive and SSD seem to start and work nonstop, but I see no signal on the monitor (which I tested on my notebook and is working). The dedicated video card's fans also work. The processor's fan works.


If I take off the dedicated card and try to use the integrated video card, the motherboard gives 1 long beep followed by 3 short beeps (?).


Tried to take the mobo's battery off for some seconds and put it back again = nothing changes.


Tried to change the memory card's slot = nothing changes.


Tried to disconnect the hard drive = nothing changes.


I have Ubuntu OS in my ssd... after turning on the computer and waiting 1 minute, I push the power button and it turns off instantly. This means, in my opinion, that the OS didn't even load.


Please advise me on more troubleshooting steps, because I am out of ideas now.


My system specs:

MOBO: Gigabyte B85M-D3PH

Processor: Intel i7 4790

GPU: Radeon HD 7870

Memory: Corsair 8GB x1

SSD: Samsung 850 evo

HD: an old unidentifiable Samsung


Thank you all so much for the forum.

This is only a guess, but.... Although your PSU should 'auto-range' and find the correct voltage, that doesn't mean that your monitor will. These usually have their own separate power supply, and tend to be region-specific; I've never yet seen one with switchable voltage.


It's more than likely this is the problem, although.....don't take that as gospel! AFAIK, no Linux OS will boot if there's no monitor in a 'working' condition, as 'seen' by the OS; even a pure command-line set-up needs a working monitor just for your terminal. The only ones that will boot like this are server builds which are set-up as 'headless'; in other words, they're designed to be run by an administrator, from a remote location, using the admin's own system & monitor, usually via SSH (Secure Shell), and over a secure, encrypted broadband connection.
