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.
