system randomly lags only fixed by turning off psu
My system randomly goes into what I like to call stroke mode and starts lagging very hard. It happens in games and it happens at idle or even web browsing. when I check coolercontrol it seems as if my cpu is being limited to around 1.5 gigahertz at idle during stroke mode and the moment it is hit with any load it drops to around 500 megahertz. and when I check uefi it pins my cpu voltage at 0.9v. The only fix I have found is to turn the computer off then turn off the psu for several minutes. Stroke mode persists through regular reboots and often through a rebase. Side note my disk capacity is 2tb not 250gb idk why system report says that.

If "stroke mode" persists through regular reboots, then I should check whether your thermals are good.
Particularly your CPU and if you have it your NVMe SSD. When these starts throttling, you will notice it.
I thought that aswell particularly with the nvme but according to coolercontrol my cpu while in mh wilds is sitting at 60c gpu is 50c at core and 60c at mem and the nvme is at 43c. this is while not in stroke mode.
record your thermals for when it does go in "stroke mode". If the issue persists through a reboot it's either something with hardware or with firmware. That's the most likely.
It could also be a service that runs every once a while
have you checked the system monitor when this "stroke mode" happens?
if its a service that's eating your resources, it will show up there
when i check system monitor during stroke mode at idle it uses 10% cpu and shoots back and forth between 0 and 100% disk usage and when i hit it with any load cpu usage goes to 100%.also system monitor reports the cpu being clocked at 1.1ghz during stroke mode. Every time I have checked sys monitor during stroke mode I have not noticed any processes using weird amounts of resources.
could it be the performance governor that bazzite uses? if so is there a way to change the governor being used?
A reboot would reset it's state.
I think it must be something thermal or hardware related, because of
The only fix I have found is to turn the computer off then turn off the psu for several minutes.That really sounds like a thermal issue.
gotcha ill make sure to monitor thermals and see what they are when stroke mode begins.
