So, the problem is a quite interesting one. The thing is, a week ago, something happened to my computer out of nowhere. It was not turning on (the day before it worked just fine).
Symptoms: when I press the power button, fans spin for like 1-2 secs, turn off, and then the same repeats. Kinda like a bootloop, but there is no post, no beeps, nothing.
Okay I thought, lets diagnose this. Tried: unplugging ram sticks, booting without ram, with one ram stick, without gpu, without hard drives, still nothing, all the same.
What came to my mind is that either psu or my motherboard were bust. Brought my mobo with cpu, ram and gpu to a friend, hooked up to his psu, motherboard booted up to uefi without a problem. Happy to have recognized the problem, I ordered a new psu Corsair CX550.
And yesterday, I hooked up that new psu to my system, booted it, everything worked perfectly, I was so relieved having solved the problem. But now the worst part: I tried to boot the pc after night, and the symptoms are the same. It is not booting. Just like before.
What I will do now is take my psu to a friend and try to boot his system with my new psu. If his system won't boot, I will know that the psu is fried. I will get it to warranty and if I get a new one I don't really want to hook it up my system again.
Now my question would be, can a faulty mobo fry the psu? Maybe anyone have ever gotten anything same?
