My PC crashes often and when I play my FPS drops from solid 60-140 to 12-20 and my CPU usage from 60% to 30% every 20-30 seconds?

My PC often crashes and when I gamble, my FPS drops from solid 60-140 to 12-20 and my CPU usage drops from 60% to 30% every 20-30 seconds… The crashes not only occur when playing video games, but sometimes Even so… My CPU usage when playing without lags is around 60% and my GPU usage is at 100% (I don't know if that's normal), with the lags my GPU usage is actually always the same… The games I play are CoD MW2 Warzone, Cs: go, Fortnite, Apex Legends and Minecraft. The lags are hardly noticeable in Minecraft…

I have just swapped my graphics card with my buddy to see if mine is broken, but that is not the case… I also installed the latest drivers for my graphics card etc.

Here are my components: Graphics card: GForce GTX 1060 3GB processor: AMD FX-8300 RAM: 16GB power supply: 500W motherboard: ASUS M5A78L-M LX3 and I have 2 external fans if that helps.

I really don't know what the problem is.

Is it a pc or a laptop?

Clean and format from the inside, in Windows 10 you can also simply remove all programs and the operating system restarts itself.

A PC… (I also mentioned it in the text)

Yes I know. There are also people who also say Pc to the laptop have no idea why 😂
