I have a Inspiron 15R Special Edition laptop also know as 7520. I bought it nearly a year ago and now I have a few problems with it.
The system gets very heated up during gaming, even though I use coolers. I checked the general health of the system and I found out a lot of errors.
The device, AMD Radeon HD 7700M Series (Microsoft Corporation - WDDM v1.20), is reporting "tv_ConfigMgrErr43". This device will not be available until the issue is resolved. The Plug and Play ID for this device is VideoController2. I found out this was the cause of the heating.
I reinstalled the graphics driver and that didn't work. So please help me out.
