Random BSOD, atikmpag.sys

Hello

Every time I try to use my pc, even if I'm playing or doing anything at all, the screen will turn pitch black, and then the blue screen of death appears. It says "Attempt to reset the display driver and recover from timeout fail" (as you can see below). My gpu is AMD Radeon HD 7800 Series. I tried reinstalling the drivers but that didn't work.

I also tried to fix the problem by following the instructions in the following post: atikmdag.sys error BSOD on startup [Solved] - Graphics Cards - Graphics Cards
It did not work out, because I still have BSOD.

The BSOD appears at any time, normally when I'm playing any game.

Please help!
