Just put together my first build in years. Of course it doesn't go as planned. Boot loops every 30 seconds. Sounds like a jet engine with the corsair maglev fans at 100%. No video signal. No beeps. ASRock B450M pro4 microatx Ryzen 2600 2x8gb 3000mhz ram Rtx 2080 Seasonic 650w platinum So I've tried removing everything and "breadboarding" it but still the same. With only cpu, hsf, 8 pin cpu power, and 24pin mobo power it bootloops. If I remove the 8pin cpu power it actually stops bootlooping, but it still sits there with no video signal and 100% fans. Tried rtx 2080 as well as a loaner graphics card on either of my two pcie sockets. No video. RAM one stick two stick any slot no dice. Clear cmos pulling battery no dice. I suspect it's a bad motherboard. Don't know what else to think. Several other people on the internet seem to have similar problems with asrock boards. http://forum.asrock.com/forum_posts.asp?TID=8545&title=no-post-and-boot-loop-with-asrock-ab350m-pro4 |

Have you tried clearing CMOS at all? Pull the battery, disconnect from the wall and push the power button for about 5-10 seconds then use the clear CMOS jumper. Leave the system disconnected from power with the battery out for about 30mins then put it all back together and give it another shot. If that doesn't help, the most common cause of boot looping on new AM4 systems is RAM. There are still a large number of RAM models that are not compatible with AM4. If you can get your hands on a stick of RAM to test with, preferably from the qvl list, you can hopefully rule out compatibility. If you still have issues then we will have to dig deeper. -------------
