Frame and operation lagging issue

[FossilCupid]

So I have had my current system for about 10 months and I am experiencing unstable frame rates lower then what I should be getting with the settings I have in the applications. The main game I am experiencing this in; as it is the main game that I have been playing since the issue has presented, is League of Legends. Before the issue started showing I would be getting 190-210 fps on high settings stably, now I am only getting a max of 64 fps but it consistently goes between 22-55 fps which is really jarring. My system is running a Ryzen 5 2600 and a RX 570. I have recently replaced my motherboard but it was doing the issue with the old one and is still doing it with the new motherboard. I am unsure as to why it is doing this now as the settings have not been changed since I got the PC. I also have been having issues with programs taking 10x longer to start then they used to before the issue started presenting.

Did you replace the motherboard with the same board or a different one?

 

If you replaced it with a different one, did you uninstall the old drivers and install new drivers? Ideally you'd do a fresh install of Windows too.

 

Make sure all your drivers are up to date. Perhaps install HWMonitor and keep an eye on your CPU and GPU temps, as well as clock speeds and utilization.

 

Are you overclocking your 2600 at all? How about the RX 570?

2600 is clocked to 3.8 through ryzen master and my rx 570 is set to 1265 mhz max which is its standard any higher and it becomes unstable. i had to replace the mother board with a step down going from a Gigabyte AX370M to a Gigabyte A320M so i would understand a little bit of a drop after i changed motherboards but the issue was happening before i changed. also i have gone through and done a full reinstall of the drivers and they are update to date according to the system. and the drivers were up to date on my old motherboard.
