It is not only minecraft cuz when i have nothing open and i move my mouse rapidly it consumes up to 40% of cpu but when my mouse is still is again like only 3%.
I noticed that almost every program i run let my cpu go up to 80-100% only a few programs doesn't and those are really low on cpu usage.
Also my sound uses up to 60% cpu but I formatted my laptop and installed windows again but it stills occur I think there is a problem with my hardware and not windows ...
I didn't had the time to open and check my laptop but I have in the weekend so then I check it.
but still thanks for the help everyone
