have a hp a610uk computer which every now and again gives of a whirling noise. having taken lid of have found fan on top of pc is constantly running. after 20 mins it may stop for a while then restart. it may do this for several hours then stop for rest of day.
the ventalation is ok as been the same for 2 years. any ideas????
an amendment...fan runs constantly but appears to "speed up" causing louder noise then after a while (maybe 20 mins) quietens back down
Noise from the bearings of fans is not unusual after a while. It is very easy to replace case fans when one does go faulty.
