i have acer 6920 g .. and my cpu fan made a noise sound one day so i cleaned it with blower and it stops working at all .. so i replaced it with another fan .. not the same one but it works but before the original fan was defected i noticed that my cpu usage is alwaays above 50 % and when i try to open movie or any thing that us the cpu well ... the computer becomes very slow
so after i change the fan the same problem appeared .. and btw the temperature of the cpu is normal not high .. and i noticed that there's a file sometimes it takes alot of processing usage "audiodg.exe" but this file is not the reason of cpu usage always
so what i have to do ? buy the original fan ? and what if the problem continues ? because i had it before the original fan is defected ?
or maybe its software problem ? or maybe a virus ? btw i have kaspersky internet security and updated everyday
