Hard to run a memtest when it wont boot but got an update. I finally got it to boot from a Linux USB stick and everything checks out fine including memory. Loaded a fresh windows on the go install onto my external drive and booted just fine from that via usb but plug it into any sata port and again, starts to boot then goes black screen no signal. The problem seems to be sata related so either the board is fried or maybe you're right and the PSU isn't powering sata properly. I've got another psu burried in a closet somewhere so once I dig that out I'll give it a try.

I could be totally wrong and maybe someone will have an answer for both of us but this seems to be a quirk of some AMD boards. My 470 board with a 2600 and a vega 56 has never done it but my 350 board with a 1400 and 5x RX-580s does this all the time.

OK, a couple years ago I built an overkill htpc for my mother with leftover parts from upgrading my gaming pc. It has worked perfectly until a storm last week that seems to have killed it and her oven's control board. With some work I have got it to post to bios and everything looks fine there but it refuses to boot to windows no matter what. First the specs: I5 4670k cpu One of the high end Asus z87 boards, can't remember the exact model. 2x4gb of ram An RX-570 gpu. At first, it refused to post at all. First step was to clear cmos, then remove the gpu and try to get it to post just from the igpu, no dice. Then I started swapping around the ram sticks and sure enough, one seems to be dead but with just the other one in it, it will post to bios and everything checks out but won't boot to windows. The little dots in a circle pop up but then the screen goes blank and says no signal. After several failed attempts, windows recovery pops up. I tried doing a reset and that seemed to work fine until the first restart and once again, blank screen no signal. I tried another known good HDD with windows on it in another sata port with a new cable, same thing. I tried re-seating the cpu, same thing. I tried booting from in SSD in an external enclosure via USB, same thing. Finally I tried a fresh install of windows from a usb stick. It goes through the whole install process just fine until it restarts and again, blank screen no signal. I'm running out of ideas and think the board or cpu are toast but it posts so I'm not sure. My last idea is maybe that one ram stick is also toast but somehow good enough just to post. Is that possible? I don't have anymore ddr3 laying around but I could rip a stick out of my work computer and bring home for testing. Anyone have any more ideas before I order new parts?
