So i am having this strange issue, my system is running fine when i take out my graphics card but when i put my new gtx 1050 it gets very slow while booting and after windows logo it takes 15 minutes to start welcome screen of windows 7, and then when i use my system it very it cant even run songs and i can play new video at all.
Another thing i have noticed that my windows rating is weird, system has gave graphics card 7.1 something ratio and desktop performance for windows aero has very low 2.3 rating how can it be possible??
