Hi,
A strange CPU behavior has appeared yesterday.
No matter, what I do, it rapidly heats up, and cools down.
In idle it's 30c and stable.
E.g I lauch browser - temp goes up to 50 or even more. (monitoring in aida64 and mobo onboard display), after the browser has loaded (1-2sec) the CPU goes back to 30c very fast. CPU fan rpm goes up and down, while the CPU temp jumps.
I click any link, open any document/programm (heavier than notepad or paint) and cpu temp jumps 30-55 and back.
In BIOS the fan is set to quiete mode.
CPU cooler attached well. (I think the temp wouldn't be 30 in idle if the cooler was loose).
Does anyone have any ideas?
