Issue regarding CPU upgrade (boot looping)

[Evanokato]

Hello,
Long story, would really appreciatie if you'd take the time and read it.

So i was using a ryzen 7 1700 on a asrock B450 pro4 with stock cooler for 3 years apart from rare crashes and bluescreens there weren't any noticiable defects. I decided it was time for an upgrade. I updated the bios to version 5.00 before installing the new CPU.
I got a ryzen 5 5600x second hand and also bought a gelid solutions phantom cooler. The cooler was working fine with the 1700. At the guys house, the cpu was working fine, I kept in touch with him and it was clearly working on his pc so i dont think i got scammed. Then, when I first booted it with the new CPU, it would get into windows fine, and after 10 sec it would freeze and restart itself. After that, the period of time it gave us before freezing became shorter and shorter until it froze before letting me see the login screen. However, in secure boot (the option you get after the system restarts 3 times) It would sometimes give me a couple minutes before crashing.I could get into the bios and the cpu temprature was not high (34 - 43 Celcius) Once it even stayed on for about 30 minutes until I shut it down myself. After reading on a forum it could be an issue related to the ram so I reseated it. After then it got bad. Now its stuck in a never-ending boot loop. It boots, then just restarts itself after having all the fans spin at maximum speed for 25 seconds while the screen stays black.

Link to the mobo http://www.asrock.com/MB/AMD/B450%20Pro4/#BIOS

what we tried:
Different (the one I had in it first) cpu
Different RAM (tested on each slot)
CMOS battery reset 20 times
CMOS header reset via motherboard
Turned on without a video card
Clean install windows (back when it still booted)
New motherboard (still same issue)

Lmk if you have any questions i really want this fixed :(

changing the cpu did not make a difference

Do you mean that with either cpu installed, you still get the loop?

In this scenario, would anyone still suggest re-flashing the BIOS to an earlier version? This is significantly more risky, I'd imagine. He says he cannot boot into Windows at all now.

yes.

i got the 4.50 version in which they introduced support for ryzen 5000 series it didnt change anything

Also important note: i cant install windows. when i get to the final step which is booting it shows this message:

your pc got restarted unexpected or there was an unexpected error. the installation of windows cant continue. click OK to restart the pc if you want to install windows

and when i did that it just restarted and showed the same thing

also i get error codes

File: \BCD
Error code 0xc0000098

Error code 0xc0000001

Also, i followed this guide which didnt solve anything sadly

Those again point towards power issues, I really don't think this is BIOS related and any attempt to flash a BIOS with probable power issues will risk bricking your board, best thing to do is go replace the power supply, worst case you end up with a spare one.

Since you still get the issue with either CPU installed, I'm not entirely sure. I would make sure that the motherboard has all the power cables properly connected. Make sure everything is clicked in properly.

I know some motherboards have a CPU-4 or 6 pin and then another right next to it for higher powered CPUs. Please make sure you have PSU cables going to both of those CPU power connectors on the motherboard if you have more than one. Looks like you just have one 8-pin EPS connector on your motherboard so make sure if you have a 6-pin + 2-pin PSU cables that the +2 pin part is fully seated.

Make sure you also have every power connector on your GPU populated by a cable from the PSU, and it's the right connectors going to it.

Motherboards can only supply 75w from the PCIe slot. Each 8pin connector on a GPU supplies ~150W.


This definitely seems like a failing power supply, or improperly powered components/insufficiently plugged in.

Please make sure your motherboard not only supports 5000 series CPU's but SPECIFICALLY the one you're trying to install. Some motherboards will only support lower powered models of the 5000 series. I.E. a motherboard with only a 4 pin CPU power connector will not be able to sufficiently supply enough power to a Ryzen 7 5800x, or even a Ryzen 5 5600x. These are 105w and 65w tdp CPU's respectively, however the power surge to power these CPU's may easily exceed those numbers, as will putting load on them. My 5800x consumes about 140-160w at gaming/max load iirc. A 4 pin CPU power connector can only supply 155W, and 8 pin = 235w

EDIT: Also inspect your motherboard for leaking or bulging capacitors. This could cause an issue in power delivery. You said your motherboard is about 3 years old or older. I've had GPU's burst capacitors at only 1 year old.

I have checked all cables running into psu and mobo. There just seems to be an issue with windows becasue it crashes as soon as i want to load into it, clean install or the one i had. Also in safe mode, it would crash as soon as i put load on the system like opening discord which does point to a power issue

So I would opt to try another BIOS and try and flash to it using the more stable of the two CPU's using the boot flash options. I would maybe boot into BIOS first and see how long it holds stable there. If you can stay stable @ Bios menu's for 30+ minutes then use the bios flash option and jump to either an older or newer BIOS. You mention 5.0 but there are options up to 5.3 now and it looks like base model 5000 series support was actually added in 4.6, with 5.0 being the add for the G models.

Test bios stable then try flashing to either the newest revision, or back flashing to the first supported.

both cpu's are equally stable, i have not noticed any difference when using another one

I was getting random crashes in GTA V giving me "STATUS_ACCESS_VIOLATION" with the latest Windows 10 updates and my mobo's old BIOS. I was also getting a BSOD sometimes with the error saying "IRQL_NOT_LESS_NOT_EQUAL" instead of the game crashing. These errors/crashes pointed to RAM, but I did memtest, switched ram, turned of DOCP, etc.

However, I was also getting this issue on linux on the same game.

I updated my bios and the issue went away. Could be that Asrock hasn't released a bios revision to fix whatever issue is going on as of late unlike ASUS.

Or it could be that your motherboard's VRM is going out or your PSU is going out.

If you could test with another motherboard or power supply that would be ideal.

Another thing is, most of your bios revisions say that they don't recommend updating to that revision if you're going to use Pinnacle, Raven, or Summit Ridge CPU's.

Your Ryzen 7 1700 is a Summit Ridge CPU. As such, I would highly recommend doing bios flashes with the 5600x installed instead of the 1700. Sometimes doing something of the sort can cause for corrupt bios', or what have you.

i am doing that, i'm running 4.50 now with 5600x. could it have broken something when i booted with the 1700 with the bios update?

It could have reset some of the bios defaults to different settings from the 5600x when it asks you to run setup after detecting the new CPU, possibly? I doubt it would corrupt the bios or anything like that, however.

it didnt promp me with any setups it just 'worked' right after

I think most motherboards will prompt you with a "NEW CPU DETECTED, YOUR SETTINGS HAVE BEEN RESET TO DEFAULTS, PRESS F1 TO RUN SETUP"

So that's a little concerning. Load optimized defaults or clear the cmos again?

i have done both things i think more than 20 times :)

Without swapping the CPU's out again? I have no idea besides the PSU or caps thing man.

You've made sure neither of the CPU's have bent or missing pins? I can only think besides those things that maybe a pin broke off in the socket and isn't making proper contact, etc anymore.

nope, its runs semi-fine during bios and safe boot and i checked many times as well
