I'm quite unsure of why that is, but it's been happening for quite sometime. Whenever the system jump into sleep mode after a long duration of idle, my GPU fan starts to increase to 100% which in turns makes a loud sound. This bothers me and I'm not quite sure what to do or feel, because it'd continue even after I've force reboot it, since shutting it down is impossible when it starts; system locks up, screen turns black and I'm unable to do anything
I;m not really sure what the problem is other than it starts whenever Windows 7 enters sleep mode. Also it only recently happened, since I've never had to dealt with this problem before.
My current driver installed is : 15.301.2601.1002
OS : Windows 7 x64
