Hi guys, I recently bought a new pc specs: i5 4440 , gtx 750 ti , msi b85-g41 pc mate mobo, 1 tb HDD, 700 w psu from aerocool. A few days ago my pc when i open it, it boots normally windows but after that being done there is a blackscreen for around 1 minute and then normally the welcome screen takes place. In a few words there is a blackscreen for 1 minute and nothing else in my pc has changed. I do not think it is a virous couse i got the bitdefender 2015 premioum and it didn't show anything so i am cool. I just hate waiting for my pc to open for that long and i get really frusturated about that !! Any ideas for how to fix it guys?
