Ahh... Where do i find a spare 750w psu.... I don't have any, kittyfish. And maybe it's the mobo? Because i have Asus z170 pro gaming and it has some error led that would show u what's wrong. Now the only led that is lit is dram. I tried switch the ram
slot and still same. Then i removed the rams and listen if there any beeping sound. For the psu part, the psu led and fan are running fine. And my graphic card fans normally wouldn't run on boot or idle. The fans will only run under load but now even the graphic card fans are running.
