hello guys i'm having a terrible issue , everytime i run any kind of game i'm facing a black screen delay for about 2-4 seconds then the game starts , also i'm getting the same black screen delay whenever i click alt+tab so i can switch from game to desktop , i just don't know what is the cause of this issue at all
things i've tried to do :
1) flashing the latest bios
2) reinstalling graphics software
3) reinstalling the game itself
4) and finally installing a fresh clean copy of windows 10

and yet still no improvement at all , i've compared it to my freind's pc and his pc responded very quickly when i click alt+tab in any kind of game on his pc the pc responds quickly and switches the windows to desktop. knowing that he has a lower specs than my pc specs :(

my pc :
amd r9 290x 4gb
intel i5 4690k
g.skill (2x4gb) 8gb 1866 mhz
gigabyte z97x gaming 7
WD 1tb 7200rpm
samsung evo 850 250gb SSD
