I have a pc with high specs but unfortunately, it slows down from time to time so I checked the usage of the processor and ram [i7 processor and 64 Gb of ram] then I noticed that there are no pressure on the processor or the ram, so I thought it may be the heat that is causing the pc to slow down but when I checked the temperature of the cpu it was 57C maximum, and then I said it may be the viruses so I formatted the pc and reinsstalled windows 10, still my pc is slow !!!, and now I have no clue why is my pc slowing down.
It slows down for seconds and then returns to normal, If it happens once in an hour I would be ok with it but it happens very often, what makes me confused is that I have a pretty powerful pc and It is slow how that happens.
Note: It wasn't like this when I bought it it was fast but after 4 years it became slow.
sorry for the basic English, English is not my mother language.
