Some questions Dell Vostro 3750...

[Blitz Blitz]

Hi, I bought new samsung 850 evo ssd. But I think, I don't get full performance of it, or there is problems with something else. Windows boots faster than ssd, installs also faster, but I feel lag, or stuck sometimes. Achi, rapid mode enabled, make system optimization and set to maximum performance, Maybe I need update firmware, or something? Install additional software?
One more question, should I use drivers from official dell website? Interesting about video drivers. I downloaded newest graphics drivers from intel and nvidia, but I think they are not fully compatible, or have problems. One more question, should I intall drivers first, or make windows update? Windows 7. Sorry for english...

To ensure full compatibility you should only install drivers from Dell's support website, that includes the graphics drivers.
