I've noticed this ever since I installed RS3, and I've reinstalled it a lot so it's a consistent issue. When I first install Windows, it boots up super fast and the loading animation icon just rotates for 5 seconds and I'm already on the desktop. But after installing my drivers, I notice that the loading animation starts spinning, then pauses for about 3-5 seconds, then continues spinning and Windows continues to boot. I have the latest drivers listed below,. I'm on a RAID 0 setup and my laptop specs are listed in my signature: 1) Intel Chipset Software v10.1.1.45 2) Intel Rapid Storage Technology v188.8.131.520 3) Intel Graphics Driver v184.108.40.20649 4) System Control Manager v13.017.06089 5) nVIDIA GeForce Driver v390.65 6) Realtek ALC899 HD Audio Driver v220.127.116.1102 / Nahimic v2.5.19 7) LAN Killer E2500 Driver v18.104.22.168 8) Realtek S5250 Card Reader Driver v10.0.16299.21304 9) Killer WLAN Driver v22.214.171.1248/BT v10.0.0.448 10) Synaptics Tochpad Driver v126.96.36.199 11) Intel Management Engine Driver v188.8.131.524 12) ENE Radio Switch for Airplane Mode v184.108.40.206 13) Intel Thunderbolt Driver v220.127.116.11 Anyone experience this?
