I could use some help. I bought an old Dell Inspiron N5040 . It has no OS and what appears to be a new Samsung 850 EVO installed and 8 GB of RAM I installed. ON boot up the screen is very dim. Also when I tried to install Windows 10 on the SSD it's stuck on the opening Windows logo. It then shuts down. And once when I tried again after logo I got BSOD with "kernel Security Failure" and then it tries to boot into Windows again. I tried installing with USB and then Windows installation disc with no luck. Can anyone give me some idea what's wrong and what to do? Any feedback is greatly appreciated. I've read a few things on the Microsoft website on what to check for but I have no OS. Thanks. CPU is an i3 M380.
