Hello,
Just got a i5 6400, before had pentium g4560, replaced the i3 with i5, pc turned on, everything was fine, until I opened a game, for example CS, it shows that im having there 40fps~ in menu, but before with the g4560 I had almost 300fps.
Tried to update the i5 drivers, downloaded several of them from Intel website, but after trying to open up the installation window, it shows that Something Went Wrong, and no Driver was found that can be installed on the current device, exit code 8.
Any suggestions?
