Built a new system using a Asrock Z370 Extreme 4 mobo. Processor is a Intel 8800k and PSU is a Corsair HX1000.
Got it together and hooked everything up. It posted and I went into bios and began setting up. I observed two of my HDD harddrives were not listed. Neither was my Asus DVDRW. The bios showed those SATA slots as empty despite them being hooked up properly. I began to fiddle around, fearing I had a bad motherboard. This consisted of me testing different SATA cables, different power cables, and even bringing in a new PSU. That's where the problem arose. When I hooked in the new power supply, a Thermatek 750watt, the mobo would not even turn on. The lights on the mobo came on briefly, then went off suddenly. So I went back to the Corsair and now it's doing same thing. Mobo lights come on for a split second and immediately go off. Wont turn on again, won't post.
I did paperclip test on both PSU and they both passed. Is the mobo fried? If so, how could that of happened by switching the PSU and using the same cables? They are both modular so it was a simple switch. Unfortunately my supplier no longer has any Asrock mobos available so this is likely going to be a month delay on getting this system up. Is there any chance the mobo is okay and I'm doing something wrong?
As a side note, I have since taken the mobo out of the case and set it on a bench. I was worried maybe it had moved slightly and was shorting out on the mobo mount. However, this changed nothing. When flipping the PSU unit to the on position, the mobo lights up for a split second and then is dead.
UPDATE: Placed mobo back in case. New screws used. Case checked thoroughly for anything that could be causing a short. Using 750 watt power supply mentioned earlier, plugged in just the 24 pin, CPU pin, and one SSD. Turned power on PSU and lights lit up, brief second, then went dead again. This time after I unplugged the power supply and turned it off, a few seconds later the lights illuminated again for a split second.
