Bottom line first : if you have boot-up issues (even if you think it's DOA), remove & re-insert your RAM sticks.I've been using my ASRock Fatal1ty 990FX Pro motherboard for 8 years (it still runs solid). That was my first Asrock MB ever. Having built my PCs for 3 decades; all my previous (Asus-Gigabyte) MBs wouldn't last for more than 3-4 years (mind you; I never overclock - I'm not a gamer). Having such a solid performance with Asrock; I wanted to both have a backup MB (in case if that dies after 8 years) and also to upgrade M2 PCIE disk.AMD FX8350 is a quite powerful CPU for me and I wanted to stay on that platform for years to come.So my target was only to change MB and not re-install Windows 10 (as I have tons of photography software installed, I didn't want to go thru hassle of re-activating all my software). So I chose this ASRock 970A-G/3.1 MB. Actually, as of today if you want to have M2 with your 8350 CPU; that's the only single choice you have. For that reason; (few remaining sellers) did increase their price on this (not top of the line) MB of it's time.So I cloned my C drive (SATA SSD) to a new Addlink M2 drive (using AOMEI Backupper Pro software). Then I transferred all my other existing components (video card, 4Xram modules, power supply and other drives) on to this MB. Therefore only new component is this new MB. Windows 10 initially automatically updated few drivers and didn't even need to be re-activated (that was so smooth transition for my situation).But then I noticed an interesting thing : on every SECOND boot-up; BIOS screen doesn't come up. Power supply turns on (drives spinning up - LEDs on) but no activity on MB. Interestingly; even the reset switch doesn't function. I had to keep power switch down for 5 seconds to power down. Then on second trial everything works just fine! Then next bootup; same issue. Something was simply hanging MB - and letting work on second try. So I first suspected M2 drive (potentially freezing PCIE bus?). MB manual says that; onboard M2 socket share the data bus with PCIE4 socket. It also ask you to use PCIE2 socket for your video card. I had a PCIx16 riser for M2 drives. So (to make sure the onboard M2 socket is not the causing the problem); I took my M2 drive off of MB socket and placed it on a riser card (I had) and installed it on PCIE4 socket. Same exact problem. Then I swapped my video card to PCIE4 socket (although the manual doesn't suggest) and put my M2 riser in to PCIE2 socket. Same problem. In mean time I played with all available BIOS settings; nothing helped. Then I thought that may be my ram modules somehow didn't have exact compatibility with this particular MB. Luckily I had another set of 4XDDR3 RAM sticks. I swapped them; this time MB even doesn't boot at all (after many trials). So I put back my original RAM sticks (in picture) and my problem suddenly disappeared. Now I can boot just normal every single time. No issue whatsoever with Windows 10 or anything else.That tells me; either my particular MB RAM sockets has an intermittent loose contact issue or the sockets Asrock used on this MB has slightly rigid mechanical tolerance (that you have to insert it strongly, in order to have them establish full electrical contact).Asrock seem to released this MB in 2016 (almost final days that AMD FX CPUs were being phased out for new Ryzen platform). Then no BIOS updates at all. BIOS on this MB is a bit quirky as well (specially UEFI); once your Windows boot is settled down; it forms a "Windows boot" item in BIOS boot options (check attached pic). My previous Asrock MB didn't have that item in UEFI. You can also choose "UEFI boot" or "hard drive" boot from boot priority list. But once it boots up fine; next boot will default back to "Windows boot" option anyway. There is such organic interaction between UEFI of this MB and Windows 10.Another interesting quirk is; USB 3.0 and USB 3.1 ports take few seconds to become live as you are booting. In other words; they don't activate immediately - but USB 2.0 ports does. I have an external very high speed (UHS-II) SD card reader which is connected to USB 3.1 port. It has a power LED on it. When I turn on my PC; main power LED on my case turns on immediately. But LED on that SD card reader only turns on about 3-4 seconds later. Another clue I had was; (I have Logitech wireless KB+mouse set with USB dongle). Initially I had randomly connected to USB 3.0 port. But then I wasn't able to go to BIOS (by hitting delete) during bootup. Why? Because that USB 3.0 port wasn't active first few seconds (then it boots Windows straight). Now I switched that dongle to USB 2.0 port and it works instantly.Very particular MB indeed, that you have to patiently solve mysteries layer by layer...My Addlink M2 drive is of the latest PCIe Gen3x4 type. Of course on this MB it runs on PCI Gen2 data bus. But still; my previous SATA SSD 380MB/s read / 410MB/s write times have jumped on this M2 drive to 1570MB/s read / 1430MB/s write. Quadruple performance gain for me - no complaints there.There are quite some negative reviews here that this board dies after few months. Only time will show longevity. I'm hoping that it'll last as long as my previous Asrock MB. Even if not; I have that one as backup.Also there are quite some DOA feedback on on other reviews. I suspect that some of these instances might have to do with my above mentioned RAM stick observation.Last tip (if you want to get maximum computing power from your 8350 based PC); consider upgrading your RAMs to 32GB (if you are not already there). Search that other famous marketplace for 4X8GB DDR3 1600 RAM and sort for low price. You'll see some red & green (never heard of brand) Chinese memory modules for almost half-price of known brands. No fancy heat-sinks etc. But they perform perfectly well (that's what you see in my other pic). This MB also supports 64GB total memory. But 16GB RAM modules are very rare and incredibly expensive.
