hi everyone. intro i am not english , i can understand english but i am from italy , i would like to say this first because i might happen to not understand certain terms if they are to much specific , so i'm sorry if ever happen to ask someone to repeat the question or the mean of the things they are saying. i'm typing this message using my knowledge of english and i am not using a translator. how did i find this forum lately my computer begun to act a little strange , so i begun to search some answers on the net , the questions are , why is my graphic card heating up while my sistem is on idle ? why does my cpu jump from 0% to 50% from time to time ..always when my system is on idle ? regarding the first question i found this problem to be more common than i thought and many people says it can be a miner malware . i kept searching for results about mining malwares and here i am , google found this forum for me. wha's happening when i leave my computer for some minutes i hear the GPU fan running like hell , if i check it's Temperature with GPU-Z or MSI afterburner or windows 7 gadget it goes up to almost 90°C. plus i can see my CPU usage spiking from 0% to 51% every 10-20 secs , always when computer is in idle state. can you help me getting rid of this problem , or at least understand what is happening exactly ? thanks for your patienceù regards jumbott
