Provide a detailed description of the issue you are experiencing and the steps required to reproduce the issue.
Since changing previous GPU (Gainward GTX 770 2GB) my brother has problems with PC crashing during one game, Heroes of the Storm (LoL and DotA alike). I used 17.11.1 drivers back then. Everything works perfectly fine until crash. So far he received BSOD (apparently there was a problem with WiFi receiver Netgear WNA3100, it didn’t cause any problems with Nvidia), plain green screen and noise screen. During these moments speakers start buzzing and fan starts spinning very fast (it’s clearly audible. Although my brother is not sure which one it is). I have tried reinstalling system Windows 7 (because it was tad messy, too many unused programmes and files all over place) from pendrive, installed only necessary programmes and drivers (this time newer Adrenalin 17.12.1 were available). With newer drivers system doesn’t crash so often but it still occurs from time to time.
Details about applications/games affected (including version number)
Only Heroes of the Storm, latest version (it’s pure multi player, so always up to date).
Graphical settings used in the application/game (resolution and 3D settings)
Highest possible settings, Ultra. Resolution is 1920x1080
