For some time I have the following problem:
When I start the PC, it sometimes happens that I can not get to the desktop. I have to restart the PC. When surfing, it often happens that my screen just turns black. Only when gaming my PC never crashes. I have already exchanged all components and I think its a GPU problem. Maybe a driver problem? I already deinstalled the driver several times... and installed it then...
I really dont know the problem 
I gave my gpu to my father but on his pc it works fine... but not on mine
this problem was there in windows 7 AND now in windows 10.
Current components:
Sapphire Radeon 290X
16 GB
CPU Type
Intel(R) Core(TM) i7-2600K CPU @ 3.40GHz
