PC Shuts off 10-20 seconds when started (after cpu upgrade)

[3nc4ypt3d]

One of my freinds had a computer with a r5 1400, asrock a-320m motherboard, with a 400w psu for a while and decided to start upgrading his parts, he got a new psu that is 500w a new 1660 super, and now got a new cpu (ryzen 7 2700x), and is planning on getting a new board because the a320 is just a massive bottleneck in general. We installed the new cpu combined with the wraith prism cooler. after we got it mounted we started up the pc... the fans, rgb and other lights all turned on graphics card started spinning. none of the peripherals recieved pwr output from the pc and there was also no video output, then after 15-20 seconds it just shuts off and reboots, and continues the cycle. we tried, unplugging the ac, clearing cmos by removing the onboard battery which made it not turn off on its own but rather keep running with no output then after like 15 mins we turned it off and then rebooted it and it went back to the classic turn on for 15 seconds and then shutoff... any ideas what it could be? i know that the a320 board is really not smthg u want to use for a 2700x but its supposed to be compatible with 2ng gen ryzen and even if it wasnt its just supposed to lower the clock speed. Either way hes gettin a new board soon but that could take a while. Anyone know anything about this kind of problem? all help or tips are welcome.

That board needs a bios update before supporting 2nd gen CPUs, did you update the bios?

No because we cant acces the bios, and would a required bios update have similar symptons to this i heard it would only impact performance and stabilty.

Put in the old Ryzen 5 1400 and update the BIOS.

You would need to update the BIOS before changing the cpu. With the old CPU installed update the bios, then install the new cpu.

Yes, these are the symptoms experience when your BIOS doesn't support a CPU.

If a BIOS version doesn't support a cpu, the computer will not boot up. There are minor BIOS updates that can increase stability, but in general they won't affect the performance.

Thank you for the information, were going to try this tommorow first thing. We fought this was way worse like a faulty cpu or smthg but that is pleasing to know that all it could be is a required BIOS update, we were searching for solutions for like 4 hours before i posted here and couldn't find anything that worked. so hopefully this works which it should.

We installed the 1400 back in and bow the pc just doesnt post, the fans spin in a wierd cycle, rgb works but no output for keyboard or monitor

If you have the new graphics card and power supply installed, try putting the old ones back in to eliminate as many variables as possible. Reseat the ram and try clearing the CMOS by unplugging power from computer, removing the CMOS battery, waiting about a minute, pressing power button, then put the CMOS battery back in, plug in power, and turn computer on.

psu wasnt faulty neither was gpu they both worked fine before we swapped the cpu, we cleared the CMOS like 300 times it doesnt do anything, there doesnt seem to be any physical damage on the motherboard (we checked capacitors) we also took out the ram and cleaned it, this changed the booting from no post booting back to the thing it was doing before, loop booting.
