Hello, I am using MSI afterbuner for monitoring my GPU temp. I don't know what happened but program shows my GPU temp is 0. But If I run an application eg. games which uses GPU, program starts to show my GPU temp. I reinstalled MSI Afterburner and my drivers but nothing changed. How can I solve this sitituation? I know mobile GPU is not supported but there is no problem some time ago. Also I don't know there is a connection but GPU1 was always Intel HD 4600 in settings of MSI Afterburner. Now GPU1:Geforce GTX850M and GPU2:Intel HD 4600.
Do you have Optimus? It uses the integrated graphics in low load situations and disables/powers down the discrete one, making the discrete GPU's sensors read as "0".
Yes I have Optimus and I found solution. New drivers cause that problem. I rollbacked to 397.64 and problem solved for now.
