My Dell inspiron 15R SE (7520) running super slow

 Hi , i have a dell inspiron 15r se with config:-

I7-3632, 8GB RAM, 1TB HDD, 1920*1080 display .

but my laptop is super slow , i think of upgrading to samsung evo 850 ssd and 16gb ram

NOTE:- my laptop didnt came with 32gb ssd

so my question is that will my laptop support this samsung 850 ssd and i can i use both ssd and hdd combination , and also why i my ram show 800 mhz speed, does this laptop ship with 800mhz speed ram

Boot your machine

Start Task Manager as soon as possible

Click on Disk

See what is the app clogging your hard disk (Microsoft) at startup

Go Task Scheduler - Microsoft - Windows - find out the app and right click it for: DISABLE

You can have only one internal hard drive, so the SSD will need to replace the hard drive.  If you want to use the hard drive, it'd need to go into a caddy adapter and replace the DVD drive.

DDR-1600 RAM is 800 MHz;  that's normal.  It's what double data rate means.

Does the system correctly identify the AC adapter or it it showing "unknown"?  F2 at powerup to check.

You might also run a full hard drive diagnostic (F12 at powerup).
