PC becomes very slow after some minutes or sometimes hours +(Kernel Power 41 event)

So right now im not sure what started to cause this problem, my pc was working fine like 1-2 weeks ago. This problem started lately im not sure if i messed it up by changing Power Plan settings or this came after some windows updates. But also i was getting Kernel Power 41 Event without BSOD. Please help me, thank you!

Thanks for trying to help me bro. Here you go:

*Brand is Xigmatek Centauro S C550

My pc is exactly 1 year old. And it has worked well/never had any problems until last week
Do you think there could be a problem with Windows security update 5005565 ( i heard someone was getting kernel power 41 after this update)
Also i saw im getting WHEA-Logger 19 every single minute

A corrected hardware error has occurred.

Reported by component: Processor Core
Error Source: Corrected Machine Check
Error Type: Cache Hierarchy Error
Processor APIC ID: 0

The details view of this entry contains further information

Will wait to see what Phil says. Thank you so much !

Thanks bro, I will look to change my PSU but bro please try help me with this, cause my pc never had a problem all this came suddenly.
Like now i can see that exactly after 3 hours of up time my pc becomes very laggy, like i cant even play 720p videos smooth and when i open browser cpu usage goes directly 100% for a second. A reboot fixes this but then after 3 hours the problem occurs again. The WHEA-Logger starts to appear more often when it becomes laggy, like it appears almost every second in the events viewer p.s the Kernel Power seems to be gone since i havent got it in the last 48 hours

Also i have seen that my BIOS Firmware version is very outdated, do you think that may cause something?
