Desperately Needing some advices here. I am trying to put together a pc with the following configuration but was not able to boot up at all. Asrock x399 taichi mb Threadripper 2950x 128gb (32x4) Corsair vengeance RGB pro DDR4 3200 (PC 4-25600) C16 (I?™m not planning to oc) EVGA supernova 1300w G2 PSU (I got 1300w because I planned to add 2 gpu) Gtx 1080 ti Samsung 970 EVO 1tb Barracuda had 2gb Be quiet dark rock pro tr4 cooling fan Lancool II case When I first turned on the power on PSU after putting it all together, none of the cpu/case fans ran, neither did the psu fan, only the blue LED behind the asrock gear lit solid (no flashing). Nothing changed whether I pressed the power button on mb or on the front panel. And dr. debug is not lit at all so there is no debug info. To troubleshoot, I first verified that the PSU is functioning correctly by plugging the 24pin mb power, and 8 pin atx/cpu power into a PSU tester (note that I did plug in both 8 pin and 4 pin to mb when I tried to boot up. But the tester only takes one 8 pin). It appeared to produce the right voltage. Furthermore, the psu fan turned, which I did not observe when connecting to mb and powered on. Then I decided to take out the mb from the case and remove one component at a time, including removing ram, cpu, the situation remained the same. I have also tried to swap out the Corsair ram and put in with another two sticks of gskill ripjaws v 8gb, 3000. Then tested it along with just cpu, no luck. Tried to reseat the cpu, same thing. Also note that the psu fan did not run at all. A picture is provided here shows what it looks like https://imgur.com/a/oSoo4yE I have to admit that the last time I put together a pc myself was ten years ago so I hope I didn?™t miss anything obvious here. In this bare minimum testing, what should I observe in terms of psu fan, dr debug, etc.? Also, I did press the power switch on mb, nothing changed. Anything else I need to do? Btw, I also tried the cmos switch, and take out and put back the cmos battery. I saw some discussion about bios update, but not sure if it?™s relevant at this point. Any suggestions? |

Faulty motherboard?
I mean if RAM is faulty, you get dr debug or some LEDs light up and warn you, if GPU is dead, you also get everything light up and tell you GPU is dead. I'm yet to come across dead CPU, so have no idea how system behaves with dead CPU. |
