Hello.
Three days ago, I've built myself a new PC, consisting of these main components:
It's in Fractal Define S case, my CPU cooler is Enermax ETS-T40-W, HDD is Seagate Barracuda 7200.14 (1TB), SSD is Samsung Evo 840 (240GB) and GPU is ASUS STRIX GTX 960 but that's all irrelevant I think.
Everything was working fine, but then someone turned on a vacuum cleaner and it blown the fuses (I'm not sure if I'm using the right term, I'm talking about these). The PC turned off and when we switched the fuses back on, the PC wouldn't turn on. Like when I pressed the button, nothing happened, no sound, nothing started to move, nothing.
I tried disconnecting the PSU for a while, resetting the BIOS (I jumped the JBAT1 pins - all according to manual), taking out everything unneeded (the only things I left in there were the PSU, MB, CPU + cooler and RAM) and then turning it on, jumping the power switch pins (in case of broken switch - you can't never be sure I suppose) and nothing, the PC didn't turn on.
So I took out the PSU and tried different one (that I know for sure is working) with all these variations and still nothing.
I also did the paperclip test on the EVGA PSU and the fan spins - indicating that the PSU is okay.
My MB has these three LEDs that are supposed to light up if CPU, RAM or GPU are missing/broken, but they probably don't work when the PC isn't booted up - I think this is the case because I took out the GPU and the GPU missing/broken LED didn't turn on.
When I turn on the PSU, an LED next to the 24-pin connector on the MB lights up, but it isn't labeled and there isn't any mention about it anywhere in the manual nor the internet - I think it is just an indicator that the MB is getting power, but I can be wrong. Also, the LAN connector on the MB starts blinking.
When I had the GPU still in the PC, when I turned on the PSU, there was an white LED glowing, and when I disconnected the 6 pin PCIE connector from the PSU, the LED on the GPU started glowing red - indicating that it works, is connected to the MB, but doesn't have the neccessary power from PSU - this tells me that the GPU is probably working fine.
Also, with both of the PSUs, I tried cycling the RAM - taking out both sticks and then trying to start the computer with only one of them (I tried both of them) in the slot that the manuals says should be populated when only using one stick of RAM.
Can someone tell me from these informations which part is most probably broken and also why could it have broken? I thought that the PSU was supposed to prevent damage in case of power outage/surge (I don't know how to call it).
My guess is that there's something wrong with the MB, but it's weird since there are lights on it that work and also it was giving power to the GPU. But if the problem was something else than MB, something would happen when pressing the power button, wouldn't it? Like, at least for a few seconds or something, the fans would spin, or the beeper would beep or... Something.
Can you give me advice on how to solve this situation? Everything is still in warranty, so that shouldn't be an issue, I'm mostly trying to determine what is broken, so I can get that part replaced.
Thanks for all and any help.
