Computer Freezes, Reboots After 6 Seconds of Post

[MStephensRich]

This is a new one, that I have never experienced.  Regardless of if I am trying to boot into a hard drive with installed Windows 10 (which I have tried), booting into a Windows 10 install media to install Windows onto a blank drive (also tried), the motherboard will post for a few seconds, crash and freeze, and reboot.  It will reboot for ~3 times, and then generally crash with fans whirring, but no visual posting to the monitor.

 

Here is the system build rundown:

CPU: AMD 2600X
Mobo: ASRock B450M Pro 4 (Used Bios control to auto install latest bios)
HDD: Tried installing to Samsung 840 EVO SSD and WD Blue 500 with no luck
Graphics: Nvidia 980 and AMD Vega 56 (tried both cards to see if it was a graphics issue)

PSU: Corsair 550 watt

RAM: Team Vulcan 8GBx2 (total 16 GB)

 

Any insight or thoughts are greatly appreciated!

Have you tried taking out out a ram or placing them in different slots? Could be that or maybe a power supply issue if it wont post to your monitor

Indeed tried reinstalling/moving RAM to different slots, no luck.

Motherboard with will post, but only for a few seconds.  (Boot into Windows, then crash on login screen). Would this still be indicative of a bad PSU?

Not so sure? A dead psu wouldn't get pass the windows loading section. And you tried a windows installation usb? Does it crash while you're setting it up or before you can even see the installation?

Before install.  Windows logo will load, and will get the dotted, spinning circle load animation for one or two animations, and then crash and reboot.  Very weird.

Have you tried a bios reset with either the cmos or jumper pin? Also try booting with one stick of ram

Will give it a shot on jumper pin and report back!

Reset CMOS with no luck. Computer will not boot to flash drive nor hard drive with preinstalled windows.

To close this topic and provide the solution - it was the RAM.  While the RAM was advertised as working with AMD, it was not Zen-ready.  ALWAYS DOUBLE CHECK YOUR MOTHERBOARD RAM LISTINGS WITH CERTIFIED RAM!!!
