If it's not a BSOD, the dump file is likely to be useless.

It could be hardware-related, like weak caps, RAM going bad or voltage fluctuation.

First move is to use another PSU to see if the problem persists.

And I will add the suggestion to look in Reliability History. (Event Viewer can be used in much the same manner but is not as user friendly.)

Windows may be capturing some error code, warning, or even some informational event that corresponds with the restarts.

"Once a day, at or about the same time, after some app has been opened or closed? Look for a pattern.

I have already tried : replacing PSU from 600W to 700W, replacing RAM , system format, I bought UPS, Replacing GPU, Replacing system disk, and the problem persisted

The S9-700 appears to be a decent quality PSU. If the problem persisted after trying it, I suppose that rules out the PSU as the main problem.

How long ago did you put the system together and how long have you been having the reboot issue? Did you make any hardware changes around the time reboots started? Do the reboots appear to be more frequent when you are doing something in particular (ex.: loading/exiting games) or truly random (happens about equally between idle, intermediate and full-load conditions) with no apparent cause?

Another common cause of random reboots or no boot whatsoever is IO shield ground tabs sticking into ports and shorting them out. In that case, the issue would usually be present from the time of (re-)assembly.

If you have any non-essential hardware in your system, remove all of it and see if that helps. If random reboots go away, then one of the devices that were removed might be the cause.

You sent a dump to Gardenman, he asked me to look. It doesn't really show a driver name
https://jsfiddle.net/cLgz9wvy/show
Oct 29 2013RTKVHD64.sysRealtek Audio System driver https://www.realtek.com/en/
oldest driver is Realtek Audio from 2013, I would question where you even got it from since the drivers on Asrock website are from 2019 - https://www.asrock.com/mb/Amd/B450 Pro4/#Download

I could guess you have a Blue Yeti microphone based on
Nov 28 2016CMUSBDAC.sysC-Media USB Audio Class 1.0 and 2.0 DAC Device driver https://www.cmedia.com.tw/


try updating lan drivers, 4th link down under WIndows here - https://www.realtek.com/en/component/zoo/category/network-interface-controllers-10-100-1000m-gigabit-ethernet-pci-express-software

try updating bios, it might help. https://www.asrock.com/mb/Amd/B450 Pro4/#BIOS

today i had pc freeze that i cant do anything , only restart pc manualy.
Run memtest86+ for ~10 hours, see if any errors come up. There shouldn't be any.

If you get multiple errors at the exact same few places, you have bad memory bits and need to replace the RAM or at least remove the offending DIMM until you can replace it. Other error patterns would indicate a bus issue which can be caused by the CPU, motherboard or the DIMM and its chips which may or may not be fixable with bus voltage tweaks.

its the top link on the asrock website

Realtek high definition audio driver ver:8730.1
This download contains only the driver package, the Realtek Audio Control will be downloaded via Microsoft store when an internet connection is available
their website is supposed to also link to this faq to explain drivers - https://www.asrock.com/support/faq.asp?c=Audio
You may need to download the realtek Audio Console from the windows store to control the audio once you get it
