Question Pc keeps crashing 10 seconds after boot

[ReCCoR]

I tried to reduce the clock speed of my ryzen 9 7900 using MSI center's profile configurator and I accidentally set it too high forgetting the (,) and I was met by a black screen instantly.
Now pc takes really long to boot up and crashes 10 seconds after boot. I tried enabling pbo, disabling expo, nothing changed.
When the pc boots I can see my clock speeds go up to 5,10ghz and 10 seconds after it goes to black screen and reboots.
I need serious help because I dont have any idea what else to try...
Motherboard: msi x670-pro wifi
Cpu: ryzen 9 7900

To explain how amazing my mistake was, I set the clock speeds to 3050 while trying to make it 30,50 under the customized profile... My cpu was idling at 70C which looked extreme since my gpu was at 45C (notorious for its heat problems rtx3080) and I just wanted to make it idle cooler since I wasn't going to be using the pc for the next couple hours.
I am not at my primary residence right now and dont have a clean windows installation with me, I hope there is an easier way of fixing this.

First things first is to get rid of MSI Center, uninstall it. It's the follow-on to MSI Dragon Center which was pure garbage and all accounts make this one equal levels of garbage coding. Hopefully when uninstalled it completely removes itself, especially any services that it installed. Otherwise you should chase them down and remove...quite likely using "SC /delete" from command prompt with admin rights. Considering what has happened elsewhere it's quite likely one or more of them are essentially back doors that phone home at every bootup.

Then, reset CMOS. It's not clear from the post whether this is a new build where that's something you should have done anyway. But since MSI Center was fiddling with things in an indeterminate manner it's best to just start with a clean slate and resetting CMOS will do that for you. Actually, this may be needed first in order to get into Windows long enough to un-install Center.

If you really need to use a Windows based method of tweaking CPU or memory overclocks install AMD's Ryzenmaster utility. But much preferred is to do it in BIOS.

And last: abandon any ideas of fixed frequency/voltage overclocking (unless using sub-ambient cooling methods). It's been true since 3rd Gen and it's especially true with 5th gen CPU's: PBO is the best way, with Curve Optimizer for per-core undervolting. These CPU's are already being pushed to their thermal limits in stock configuration by their boost algorithm so there's no tolerance left for a fixed OC to work safely.

Even resetting cmos didn't make that msi center app to stop so my solution was to start the uninstaller for msi center by navigating through the folders and finding it before pc freezes and crashes. As soon as I hit uninstall it let my cpu speeds to the default unlocked speeds. I wasn't able to boot into safe mode either for some reason.
After I have seen that nothing changed even with the cmos reset and different bios stuff to stop the overclock I thought my best option was to just get a fresh windows install.
I had too many problems with msi dragon center when I was using a 3600x and I thought if they made a new app they would surely fix some things. MSI center is a downgrade from MSI dragon center..
Build wasn't new, I have been using it for a couple of months, I primarily installed the msi center app to monitor everything from one place. Even that is a straight downgrade because the monitoring is delayed...
And to add, my reasoning behind the fixed OC was an underclock to make my fans calm down a bit since it was late in the night and my internet speed requires me to download games over multiple nights of idling. I used to do this with my ryzen 3600x before I saved money to buy a scythe fuma 2 cooler (which I still am using)
To sum up if anyone else has the problem;
If you can, just uninstall msi center from the safe mode, if you can't boot into safe mode for some reason you can try to do what I did. Remember to take out the cmos battery too for the bios reset for anything else that app may touch.

Get HWINfo64 for monitoring...everything. Temps, core clocks, voltages, activity levels, fans, and much more. GPU too, all in one place. Ryzenmaster also monitors but it's quirky and not nearly as complete as HWInfo64.

The way to control fans is to...control fans. Using the BIOS fan profiles. I run a low fan speed up to 65 or 70 C since it doesn't do anything to spike fan speeds for processor boosts at idle. What's low enough depends on how quiet you want it; quiet running fans let you run them pretty high.
