Well, I tried clearing the CMOS and unplugging all the not essentials component with no luck, same problem. I neeed to make the paperclip test, the last test, but I wanted to add something that I noticed when trying the aforementioned steps:
when turning on the system, it powers off inmediately (the psu fan spins also, as the ones from the cpu and case), but after the first turning on, the next time it doesn't even turn on the half second that I said in other post. But if you mantain the finger pressing the power on button, then releasing it and turning on again, it turns on again for the half second and then turns off, but this time the psus fan doesn't spin, just the fans of the case and cpu.
I tried the paperclip suggestion (also suggested on the Corsair Technical Support) and found that my PSU is the problem, its fan spins half a second and then stops. But I will see if I can get other PSU to test if the other components work. My hard drive I will test with some friends PC, in an external enclousure, one of these days. I asked for an RMA to Corsair and I will send the power supply to them.
So which of the hundreds of caps on the bored do you think he should randomly replace?
If it was lightning, as he says, do you think those caps (which are on the output side of the PSU) would be the only hardware damaged? You may have gotten lucky a few times, but it is not that simple.
BTW, did you read the thread? He thinks he found the problem - power supply... who would have thought?Easy answers work well for you, it seems. Stick to chewing bubble gum.99% of the time when a component goes bad it is due to the capacitors in it.
On power circuits, heat is the enemy - switching components are most likely to fail. Capacitors, especially electrolytic (the kind that you are familiar with), tend to fail more often in outdoor applications (especially cold).
Point is, it is more complicated than just using bullshit figures (99%) or blindly selecting a component to replace. It is not impossible, but it is not pin the tail on the donkey either.
This needs to be said again: "The more you know, the more you know you don't know"
"...take a look at the caps to see if they are damaged."
